What makes a particular solar generator the best? How do we quantify a solar generator to know how it will work during emergencies, RVing, camping, or during blackouts? There has to be a variable that is comparable across all the best solar generator systems so they can be properly compared against each other.
3 Factors to a Good Solar Generator
There are three main factors when it comes to a solar generator: 1. Battery Capacity. 2. Inverter Size. 3. Solar Input.
Factor 1 – Basically, the battery has to be large enough to run everything necessary at a minimum through one night. Preferably, it needs to be a large enough battery to get through 24 hours or more of no sunlight to account for cloudy, rainy, and snowy days. Usually, this is a minimum of 2,000wh for very basic emergency items.
Factor 2 – The inverter needs to be large enough to run all the necessary equipment. Most common for emergencies that equipment is a fridge, freezer, small a/c, fan, phone chargers, laptop chargers, CPAP, HAM radio chargers, LED lights, sump pumps, microwave, toaster, coffee machine, washer machine, saws, tools, and so on. It does not have to be able to run all of those things at the same time, it just has to be able to run them when needed. Usually, this is about 1,500w, preferably 2,000w, all depending on what your needs are.
Factor 3 – The solar charge controller has to be large enough to accomplish two tasks. It has to be able to let in enough solar power to fully recharge the battery in a single day, which is 5 hours of sunlight. Secondly, it has to let in enough solar to run the necessary equipment during the day, while still fully recharging the battery. This generally means the system needs to be rechargeable in at least 3 hours or less in order to still run vital equipment like a fridge and freezer during the day and still get a full charge on the battery. Usually, the charge controller needs to be at least 1/3 of the capability of the battery capacity. For example, a 2,000wh battery should have about a 700w solar input. In 3 hours of sun, it would be fully charged.
I’ve also made up a fourth factor so that it’s easier to compare the price between all the units. Since this monetary measurement has never been created before, I invented it, I call it “Unit Wattage.” Basically, I take the 3 factors on the size of the battery, inverter, and charge controller, and see how many watts or watt-hours the unit will divide into the price of the unit. Then I take the average of those 3 numbers and it makes the average “Unit Wattage.” You’ll see as you go through each unit.
The Top 8 Best Portable Solar Generators
These solar generators compared here are based on specs that have been compiled into this comparison chart. There are some factors that are hard to account for and so positions in the chart can change.
#1 Best Solar Generator – Titan
The Titan, as a base unit, comes with 1 battery and 1 power module (inverter and charge controller). The battery is lithium-ion and has 2,000wh of capacity. The power module (top half) has a 3,000w pure sine wave inverter. The charge controller is 2,000w!
Of the top 8 best portable solar generators reviewed here, this has the largest inverter and largest solar input. But on top of that, has expandable batteries. This means I can use more Titan batteries to expand the Titan itself vertically, the Titan batteries stack on each other which is awesome, or I can use other batteries externally, such as the Lion Energy UT 1300s. The Titan batteries are rated to 2,000 cycles.
It is recommended to use lithium-based batteries. Lead-acid batteries are a thing of the past.
The solar charge controller is 35-145v and 30a at 1,000w. There are two of these solar charge controllers built into the power module which allows it to input up to 2,000w of solar.
It has the largest battery expandability, largest inverter, and largest solar input. But then doesn’t all of that come with heavyweight? Yes. But the Titan batteries can separate from the power module and other batteries to make it no more than 35lbs each piece which makes it one of the easiest to transport, especially for the power it has.
It is recommended to have at least 500w in solar panels on this unit because that can be charged in a day if you’re just running a fridge, fan, and a light. Really, it’s best to have at least 1,000w so that it can be charged in a few hours while still running lots of equipment. The Titan has a 2-hour charge speed with 1 battery and 1,000w of solar. Or if you have 1 battery, and 2,000w of solar, it can be charged in as little as 1 hour! The absolute fastest charge rate of any system, period.
The Titan has been running my off-grid cabin non-stop for about a year at the time of writing this. We have expanded it to have 4,000w of solar panels and 6,000wh of battery capacity. Since the charge controller is limited to 2,000w (which is almost 3x more than the next best unit) we can only input up to 2,000w per hour. But, since we have 4,000w of solar panels, this means we have 8 to 10 peak hours a day rather than just 5 hours.
Normally there are 5 solar peak hours a day depending on location and season. 5 hours x 2,000w in solar equals 10,000wh made in a day. But since we make 2,000w for more than 5 hours a day, we can actually make upwards of 16,000 to 20,000wh of power every sunny day. That is incredible!
Since upgrading our system to more batteries and more panels, we have never run out of power once. Not even during the darkest time of winter. The only time we ran out of power before was when we only had 500w of solar and we were running lots of equipment.
The Titan is customizable with however many batteries each person needs and up to 2,000w solar input. For some the Titan 500 Kit will work, others will want the Titan+ 2000 Kit because it includes an extra battery and more panels. The Titan allows you to find out what works for you. No other system really does that.
The Titan is at a fair price of $2,995 which means its Unit Wattage price is $1.33/unit wattage. This is the lowest of all 8 best solar generators. That means the Titan is literally the best bang for the buck, and it will actually cost you less to get this system over time than any other of the 8 best solar generators.
#2 Best Solar Generator – Bluetti AC200P
The Bluetti AC200P is rather new but has had quite the following due to their successful launch on IndieGoGo. Originally, they started with the AC200 which had lithium nmc battery cells in it. Then they switched to the LiFePo4 batteries because they had more power, lasted longer, and were available.
The Bluetti AC200P is not expandable with batteries or more solar panels, so what you see is what you get. It has a good-sized battery at 2,000wh which meets the minimum recommended amount. Because the Bluetti AC200P solar generator uses LiFePo4 batteries, it has an incredible lifecycle rating of 3,500 cycles!
The pure sine wave inverter is also a very good size at 2,000w which means it’s capable of running all the things necessary during an emergency such as a fridge, freezer, coffee machine, microwave, toaster, small a/c unit, and so on.
The solar charge controller is rated to 700w solar input at a rate of 35-150v and 12a. This means that this system, like the Titan, can be over-paneled, allowing up to 1,400w of solar panels to be connected. It will still only let in 700w max input, but this allows nearly twice as much power to be made in a single day.
Having the extra panels means that it is easier to fully recharge the battery each day while still running essential equipment. The Bluetti AC200P will charge in just under 3 hours for its fastest charge time from 0% back to 100%. That means it meets the minimum recommend charge time and will still recharge in a single day while running essential pieces of equipment.
The biggest downside to the Bluetti AC200P solar generator is the weight. It comes in at 61lbs. It cannot separate the batteries from the inverter which means it has to be carried all at once which makes it very heavy. It is recommended that a furniture dolly or some form of wheels be used to move it around for those who wish not or cannot carry 61lbs easily.
The Bluetti AC200P is readily available on Amazon and is at a fair price of $1,998 which puts its Unit Wattage price at $1.63/unit wattage. 2nd place unit also has the 2nd place pricing.
Complete Bluetti AC200P Kit:
7-14x 100w Solar Panels
2x 15 MC4 Solar Cable (only if you have more than 7 panels).
1x MC4 Branch Connector (only if you have more than 7 panels).
#3 (Tied) Best Solar Generator – ElecHive 2200
Before you read too much about the ElecHive 2200 solar generator, you must know that as of the writing of this article, it still has not been released and so it is untested. The only prototype that has come out has been very buggy and had many issues. Zero Breeze said it was buggy and had many issues before they allowed the prototype to be tested so they are aware of the issues and said they will have them fixed when the production model solar generator is released.
That being said, if it does everything it says it will do, it is definitely #3 on the list of the best solar generators. Anything below #3 I have a hard time recommending. And as of right now, I cannot recommend the ElecHive 2200 solar generator because it hasn’t been released yet. But I digress.
The ElecHive 2200 solar generator has amazing specs, especially for how much it weighs. It has a 2,400wh Lithium battery. With a 2,200w pure sine wave inverter. And a solar charge controller built to let in 800w at 35-150v and 12a.
This means it has nearly the same charge controller as the Bluetti AC200P solar generator but allows an extra 100w of solar in. But because of the charge parameter, it too can allow for over-paneling and allow up to 1,400w of solar panels to be connected to allow for great solar input throughout the day. This makes it easier to get a full charge while running essential equipment.
But what sets the ElecHive 2200 apart is that for its capabilities it is only 42lbs. That is considered lightweight with these specs. And on top of that, it doesn’t use the standard 18650 lithium nmc battery cells that most solar generators have, which means it takes up less space and less weight on the battery. Very smart.
You may be asking, why isn’t this in second place then? The ElecHive 2200 has a larger inverter, larger battery, and more solar input than the #2 Bluetti AC200P. The reason is the lifecycles. It is only rated to 1,000 cycles on the battery which is too bad. If it had at least 2,000 cycles for the Lithium NMC battery it would definitely be #2. But effectively, the Bluetti AC200P will last 3x longer than the ElecHive 2200 solar generator, and for that reason, it is #3.
The ElecHive 2200 started on IndieGoGo at $1,099 for the unit. That is crazy cheap! But, it is still very untested and truly doesn’t exist yet, so it’s quite the gamble since the prototype unit didn’t do so well. It is said that the price will be about $2,500 for the ElecHive 2200 once it is being produced and shipped.
This means the ElecHive 2200 at $2,500 will be pretty fairly priced right at $1.77/unit wattage. Starting to get up there a little bit in price.
#3 (Tied) Best Solar Generator – Lion Energy Safari ME
The Safari ME solar generator, like the Titan, has been out for a little over a year now. It is a long-lasting and powerful unit.
It has a powerful LiFePo4 battery that is rated at 2,500 lifecycles. This is definitely going to be around for a while. But, the biggest issue with this solar generator is that only has a 922wh base battery built into it. That is quite small and will only run a fridge for about 12 hours and not much else.
It’s hard to recommend this unit without also getting the Safari XL battery expansion or also know as the Safari ME + Expansion. The extra Safari XL battery is 2,048wh which is plenty big just like the Titan batteries. Only 1 Safari XL battery can be added to the Safari ME solar generator, but it brings the total battery capacity up to about 3,000wh.
The Safari ME solar generator has a great pure sine wave inverter that is rated to 2,000w continuous output and 4,000w surge. It is fully capable of running all the essential emergency items or an RV/van.
It doesn’t have the largest solar charge controller, but it will allow up to 600w of solar power to go in it. Because it has a 30-60v and 10a charge controller, it doesn’t have the ability to over-panel. If I’m using my typical Rigid 100 solar panels, which are each rated to 100w output, I can connect them in a 3×3 series/parallel combo configuration and get 600w of solar attached to it. But with that, I am maxing the solar charge controller parameters and can’t add any more panels beyond that.
With 600w of solar input, it will recharge the base battery in just 1.6 hours which is incredibly fast. It’s only fast because the battery is so small but still, it’s fast. With the expanded Safari XL battery installed it will take about 5 hours to fully recharge the Lion Safari ME solar generator from 0% to 100%.
It does have a nifty 12v/25a DC output port so if you need lots of DC power for a Van, RV or HAM radio setup, then that is a really good option.
The base unit weighs 46lbs by itself and the additional battery weighs 44lbs, so in total it is 90lbs when put together. Luckily, it doesn’t all have to be carried at once.
It is priced right at $2,350 for the base unit without the expansion battery. With that it gives the Safari ME solar generator a high priced $2.55/unit wattage rating. That is nearly double what the Titan is.

#4 Best Solar Generator – Inergy Flex 1500
The Inergy Flex 1500 solar generator is a very unique and cool unit. It is essentially a mini-Titan. It has half the inverter size, half the battery capacity, and one quarter the solar input and is about half the price.
The Flex solar generator battery is 1,069wh as well as each expandable battery. They are lithium nmc and are rated to 2,000 cycles just like the Titan batteries. However, the Flex solar generator batteries are only capable of running 1,500w continuously for 80% of their total capacity.
The Inergy Flex has a pure sine wave inverter that is rated to 1,500w continuous output and 3,000w surge. One of the biggest issues I’ve had with Inergy systems like the Apex and Kodiak has been the battery to inverter capacity. Essentially, the battery is not capable of running 1,500w for very long.
Inergy has said that with the Flex solar generator, it will not be limited like the Apex and Kodiak was in the past. The Apex, which was the model before the Flex, was only capable of running 1,500w for about 4 minutes before it would shut off. I hope that the Flex doesn’t have the same issue especially since they are claiming it can do more than the Apex and Kodiak.
It has a solar charge controller that Inergy says will allow 600 watts of solar power to go into it. The charge parameters are 14-90v at 30a. This means you can supposedly use either a series or parallel solar panel configuration to get the 600w, but is that true?
They claimed the same 600w limit on both the Apex and Kodiak too but it wasn’t possible. When we look at a typical 100w solar panel, it will make about 21v VOC (Open Circuit Voltage). Or in other words, the absolute max voltage it can make is 21v. It will often be closer to 18v in normal use, all depending on the sun and weather.
If we take six 100w solar panels and connect them in series which increases the voltage but not the amps, that would give us 6 panels x 21v = 126v. That is WAY more than the 90v limit. So that’s definitely not going to work.
If we look at it from the perspective of the amps, each 100w solar panel makes about 5.5 to 6 amps in full sun. Most of the time 6 amps is the max a 100w solar panel will make. If we connect the panels in parallel which increases the amps and not the volts, we get 6 panels x 6 amps = 36 amps. That too exceeds their charge parameter.
The only way to make this work is to do a series/parallel combo for connecting the solar panels. This means we will have three 100w solar panels connected in series (panel to panel to panel) in one group and then another three 100w panels connected in series in another group. There will be two groups of three panels. Then each of those groups of panels will connect together through an MC4 Branch Connector (as long as the panels you are using have MC4 connectors, not EC8 connectors). At which point you will have a 3×3 series/parallel panel configuration that makes about 63 volts and 12 amps.
Since Inergy doesn’t use common MC4 connectors on their panels, I can only hope they make some sort of branch connector to make their panels work in that 3×3 configuration. They definitely are not going to get more than 500w in series or parallel on the Inergy Flexx 1500. After many years of being in business, you’d think they’d stop advertising 600w solar input when it is truly limited to 500w. The same goes for the inverter, don’t advertise a 1,500w inverter, if it can’t actually pull 1,500w constantly until the battery is empty.
It is said that it will have an MSRP of $1,500. It comes in right at $1.63/unit wattage. That is pretty low, but not the lowest price per unit wattage. But that will go up greatly once more MPPTs and batteries are added on.
#5 Best Solar Generator – MAXOAK Bluetti EB240
In many ways, the MAXOAK Bluetti EB240 is also better than the Inergy Flex. The Bluetti EB240 doesn’t have the expandability that the Inergy Flex has and for that reason, it doesn’t beat the Inergy Flex.
But the Bluetti EB240 has a large battery at 2,400wh which is the largest so far, out of these top 8 systems, for a base sized battery. It is also different from the other units because it does not use Lithium NMC batteries which is the most common type of Lithium-Ion battery.
The Bluetti EB240 uses Lithium Polymer batteries. Most commonly lithium polymer batteries are what are used inside of cell phones. Instead of being the 18650 small cylinder cells, they are flat. One of the advantages is that it takes up less space inside the unit and therefore it doesn’t have to be as big.
One of the biggest differences with this battery is it is rated at 2,500 lifecycles. I am not sure how they got that number but according to their user manual, website, specs sheet, and so on, they claim that it has 2,500 cycles before it hits 80% efficiency which is great! 2,000 cycles is really the gold standard, so anything above that is phenomenal.
If you do the math, 2,500 cycles ÷ 365 days/year it will last just about 7 years (6.85yrs) before it reaches that 80% efficiency level. That is if you do that math based on using one full cycle per day.
The inverter is nothing to write home about. It is pure sine wave, which is great, but it is only rated to 1,000w of continuous output. This means you are absolutely not going to run anything big off of the Bluetti EB240. The EB240 is seriously only going to be good for very basic preps such as running a fridge, freezer, lights, fan, CPAP, etc.… It is not going to run any corded power tools but could recharge cordless tool batteries.
The peak output of the inverter is only 1,200w which is really low. Typically, the standard is to have at least 2x the continuous output as the peak. In this case, it should be at least 2,000w.
I have had a few different people write to me and tell me that they were using their Bluetti EB240 solar generators and they stopped working suddenly. What had happened is they were running a fridge, and a freezer at the same time and both of those units happened to kick their compressors on at the same time, causing a large surge, and overloading the system.
The biggest issue with the surge is that it doesn’t notify you if anything happens as you can see in my video. There’s no loud beeping or noise to let you know that it needs to be reset. This is another time I recommend using outlet timers because then you can schedule the fridge to run for 30mins, and then the freezer to run for 30mins, alternating when they run. This will eliminate the worry about them surging at the same time and causing that overload.
It has an MPPT charge controller that will let in up to 400w of solar. It can be over-paneled up to 600w of panels. The charge parameter is 16-65v and 12a. FYI, their earlier models were labeled 10a max input but can actually input 12a.
The MAXOAK Bluetti EB240 beats the EcoFlow Delta 1300 because the Delta has the same solar input, but ½ the battery size. The Delta has a larger inverter but it’s almost pointless to have a large inverter with a battery that small. I explain this further down.
The Bluetti EB240 is usually about $1,700 but you can use this coupon to get some savings. That brings it to a total price of $2.22/unit wattage which is a bit on the high side.

4 – 6x 100w Solar Panels
2x 15ft MC4 Solar Cable (only if you get more than 4 panels)
1x MC4 Branch Connector (only if you get more than 4 panels)
#6 Best Solar Generator – EcoFlow Delta 1300
The EcoFlow Delta 1300 had a lot of hype when it was first introduced. With a large inverter and lightweight size, it was boasting to be one of the best units available. As we can see, since it is in 6th place, it didn’t really accomplish that.
It has a rather small battery at 1,260wh total capacity. It uses lithium nmc cells like many units on the market. They are the 18650 cylindrical cells.
One of the amazing things it is capable of doing is it can run the 1,260wh battery at 1,800w output for the entire capacity of the battery. Most batteries will not push out more power than their total capacity. That means that a 1,260wh battery generally will not push out more than 1,260w of continuous power from the inverter. But the EcoFlow Delta 1300 can.
The inverter has a continuous output rating of 1,800w which is way better than the EB240 and the Flex. But, with such a small battery behind the inverter, it’s kind of hard to justify having such a big inverter. It will peak up to 3,300w off of the inverter which isn’t quite 2x the continuous rating but it’s definitely better than the Bluetti EB240’s.
The reason it is in sixth place is that it is not a big base battery. It is barely enough to run a single fridge for a whole night. This means, if it’s cloudy the next day, there’s no chance of it lasting more than a whole night which almost makes this unit useless. If it’s sunny every day then it will still be able to run the fridge all night, then continue to run it during the day, and get a full recharge.
With its same sized MPPT charge controller as the Bluetti EB240, it will let in up to 400w of solar. The charge parameter is 14v-60v and 10a. I have been able to get it up to 12a without any issues, which means it’s fully capable of running a 3×3 series/parallel configuration and having 600w of solar panels attached.
In fact, it’s impossible to attach up to 400w of solar to the EcoFlow Delta 1300 without using a series/parallel combo for the solar panels. I definitely recommend having at least 600w of solar panels on this unit so that it can be putting in the max 400w for as much time it can per day. If my fridge uses about 80wh and I’m making 400w, then I get a total input of 320wh into my battery each hour that the solar panels are making full power.
With a 1,260wh battery, it will take about 4 hours to fully recharge each day while still running a fridge. (1,260wh ÷ 320w = 3.93hrs to charge).
One very unique feature of the EcoFlow Delta 1300 is that it is able to chain together up to 6 other Delta 1300 units. Sadly, each unit will not allow you to add more solar panels, use 240v power, or increase the inverter output. But, you do get the added battery capacity. It’s a very bitter, and sort of sweet configuration. I can add more batteries which makes it expandable, but I have to pay for an entirely new unit to get that expandability.
I think they could’ve very easily made an expansion battery option that would allow solar panels to be connected to the battery itself which would double the solar input and double the battery capacity.
The biggest issue I have with the EcoFlow Delta 1300 is that when it’s used hard running lots of equipment, it tends to get very warm. When it gets that warm, it stops charging. When I did that test in my video, it wouldn’t charge again for a couple of hours. Those are very precious hours that would be lost recharging the unit, which could mean that it won’t get a full charge before sundown.
All in all, it will only cost about $1,400 which is a fair price but will end up costing $1.88/unit wattage which is not on the high side, but not on the cheap side either.

#7 Best Solar Generator – Goal Zero Yeti 6000X
Goal Zero was really the first company to make solar generators a big deal. They launched their Yeti 1250 Lead Acid system many years ago and have developed a few new generations since then. Unfortunately, and surprisingly, they have not kept up with customers’ demands since they are still selling systems that are not as good as I would’ve expected. Since they’ve been around the longest, you’d think they’d have the best systems.
The Goal Zero Yeti 6000X takes the last place in this top 8 best solar generator review because even though it has a very large battery, it is very limited in other ways.
The Goal Zero Yeti 6000X has the largest base battery size of any of these systems. It has a 6,071wh battery capacity that is supplied from the Lithium NMC battery cells. This thing is a monster. I thought the Bluetti AC200P was heavy at 61lbs, but the Yeti 6000X weighs in at 104lbs! That is a lot of weight to be moving around.
Of course, you can’t have a larger capacity without the weight, so that’s to be expected for such a large battery. But, it only has 500 cycles on the battery. That’s basically 1 year and 4 months of continuous daily use of one cycle per day before it reaches 80% efficiency. Not a very long time if you’re someone preparing for an EMP or long-term grid down situation. For camping, probably not a big deal.
The inverter is a 2,000w pure sine wave inverter that has a surge output of 3,500w. The surge/peak output is not twice as big as the continuous output which is okay, but I still would’ve liked to have seen a 4,000w peak. Overall, the inverter size isn’t necessarily bad, 2,000w is a pretty decent inverter just like the Bluetti AC200P and the Lion Safari ME.
The solar input on the Goal Zero Yeti 6000X is quite lacking. With only a max solar input of 600w, the Yeti 6000X will take over 10 hours to charge from the sun.
The Goal Zero Yeti 6000X has a charge parameter of 14-50v and 50a. The 50amp input is quite impressive, none of the other systems will allow up to 50 amps. This means the system is capable of over-paneling, but it’s not as easy as the other systems.
The average 100w solar panel will make about 21v. When panels are connected in series, the voltage is multiplied by however many panels are in that series. For example, two 100w panels in series have a total voltage of 42v (21v x 2 = 42v). When panels are connected in series the amperage stays the same. The average amperage per 100w solar panel is about 6 amps.
That means in order to just get 600w of solar panels connected to the Yeti 6000X I have to make three sets of two panels (2 x 2 x 2) making a series/parallel combo. Doing that will give me 42v at 18a. Technically, I can have up to eight sets of panels where there are two panels in each set (2 x 2 x 2 x 2 x 2 x 2 x 2 x 2). Which means I can over-panel the Yeti 6000X up to 1,600w of panels and still be within the 14-50v and 50a charge parameter. The only issue with that is companies don’t make MC4 branch connectors larger than 6 to 1. So really, it can over-panel up to 1,200w. This is good, but for every set of panels, I will need a 15ft to 20ft panel cable just to reach the branch connector.
All in all, it’s a lot of work and extra accessories to get the Goal Zero Yeti 6000X to put in all of its power from the panels. Not my cup of tea. Even the Titan+ 2000 Kit has 20 panels to set up, and it’s easier to set up those 20 panels on the Titan than it is to set up the 12 panels on the Goal Zero Yeti 6000X.
With how complicated this system is, the low cycles, long charge time, and weight, it’s really taking the very bottom of the Top 8 Solar Generator list.
The Goal Zero Yeti 6000X is the most expensive of these units at $4,999.95. That gives it the highest price per unit wattage of the top 8 best solar generators at $3.89/unit wattage. Yikes!
Complete Yeti 6000X Kit:
1x Yeti 6000X
6-12x 100w Solar Panels
1x 100ft Heavy Gauge MC4 Solar panel Cable
1x 15ft MC4 Panel Cable (every two panels)
1x Branch Connector (up to 6 to 1 combiner)
There is no doubt that the Titan solar generator is the best one available. It beats every system in every way. It has the best battery expandability, best solar input, best inverter, best portability for its size, and it is also the cheapest per unit wattage price. It seriously wins in every aspect.
If you look back to the video comparing all of these units or the picture, you will see that it is simply the best system to go with, bar none. The Bluetti AC200P is in second place, but truly, only good for basic emergency power needs. The same goes for the ElecHive 2200 and the Lion Safari ME.
The Titan sells out very quickly. The best thing to do is get one ordered as soon as possible so that you have the absolute best system around. Think about it, the Titan has been out for quite some time now, and the other top solar generator companies such as Goal Zero, MAXOAK, Lion Energy, Inergy, etc. still have not made a better unit even though they have released new units since the Titan launched.
The Titan is going to be around for a very, very long time. Get one now before the power goes out.
