The Bluetti EB70S is a good portable solar generator for travel, portability, and on-the-go use. However, it is not ideal for running a home or emergency prep for the long term.
While the other comparable solar generators of its size have Lithium NMC batteries, the Bluetti EB70S power station has a LiFePO4 battery. While a heavier battery than the Lithium NMCs, the LiFePO4 battery will last significantly longer than its competitors, meaning that were this unit to be drained every day down to nothing, it would last for almost ten years before going down to 80% efficiency, as it is rated for over 3,000 cycles.
While this is a nice feature to have, it is debatable whether this is necessary, as it cannot power a full house, and is more useful for travel than home or emergency prep use. In the event of an emergency, despite its long life, the Bluetti EB70S solar generator would be unable to power a house simply because it doesn’t have the output ability or battery size. Despite this, however, it remains a good solar generator for travel and portable use.

The Bluetti EB70S solar power station comes with multiple ways to recharge. It comes with a wall plug that will charge it in roughly three to four hours, as well as a 12v car adapter that will allow it to charge in roughly seven to eight hours, convenient for long trips where power will be needed, adding to its portable functionality. Having the car charger is another great way to be charging the unit while it’s running a DC fridge while on the road trip.
It has a max input of 200 W from solar panels, and with advanced MPPT technology that ensures faster solar recharge rates, this power station can be fully recharged via solar in three to four hours with the full amount of solar panels, though that can be affected by cloud cover.
At 12.6 x 8.5 x 8.7 inches, the Bluetti EB70S is a convenient size for transportation, featuring a sturdy handle that folds down into the top for easy portability. Though it does weigh more than some of the comparative generators such as the Ecoflow River Max and the Jackery, which are both slightly smaller, the battery life makes up for the extra weight, and even though it weighs more than the other units, it is still light, weighing only 21.4 pounds, which is still a convenient weight for carrying when needed. The weight is well worth it for the LiFePo4 battery, compared to Jackery and River Max’s Lithium NMC/Lithium-ion batteries, which are lighter but will not last as long.
It has a 12-month warranty, allowing plenty of time for testing before the warranty expires. It comes with a corded wall charger, a car charger, a USB-c to USB-c cable for fast charging small devices, a solar panel connector, and a simple, easy-to-read and understand user’s manual.
For a smaller unit, the Bluetti EB70S has a lot of ports, adding to its functionality. It comes with four 120 V AC outputs that can supply 700 W. These AC ports also have a peak output capacity of up to 1400 W, which is a nice added safety feature.
The Bluetti EB70S also has one DC, 12 V, 10A car port. It also comes with two DC, 12 V, 10 A, outports that measure 5.5 mm x 2.1 mm. There are two USB-A outputs with 5 V and 3 A capabilities, which are convenient for charging phones. A unique feature that the Bluetti EB70S has is two 100 W type-C PD outputs.
Most similar models don’t feature a 100 W type-c charger. The closest comparison is the EcoFlow River Max, which only has one, whereas the Bluetti EB70S has two, adding functionality for charging rechargeable batteries. The Bluetti EB70S has a 15 W wireless charging pad, which can be used to charge compatible phones if the other USB-A ports are being used, something which is both convenient and unique to this solar generator and the BougeRV 716wh solar generator (which is identical to the Bluetti EB70S). The Bluetti EB70S also has LED lighting that can be set to full bright or SOS flash mode for emergency use. The input port is a 12-18v, 8 A, 200 W Max port, which can be charged in a variety of ways (see Recharge).
The 200 watts of solar input is impressive for a solar generator of this size. The Ecoflow River and Bluetti EB55 are the only comparable solar generators that have the capacity for equal solar input. The Jackery and other comparable solar generators have only 100 watts of solar input, allowing the Bluetti EB70S solar generator to charge far faster than its competitors.
Another strength of the Bluetti EB70S is that it can both charge and discharge at the same time. Allowing you to charge the solar generator at the same time it’s plugged into and charging from solar panels, the wall, or a car. This means that the Bluetti EB70S can be running non-stop, not needing to stop to charge as long as whatever is running is taking less from the power station than what is being input.
After fully discharging, the Bluetti EB70S remains surprisingly cool, not even feeling warm to the touch on any portion of the surface. The fans are quiet and not annoying at all, an important feature of any generator that will be used for portability or travel, particularly if it will be used when camping or in an RV or trailer.
The 200 W of the Bluetti EB70S solar generator is capable of running a laptop, a USB charger, a fan, LED lights, and other small appliances, making this convenient for travel and adventuring.
The Bluetti EB70S can run a fridge, but only for about six to eight hours. Helpful in a pinch, but long term, it’s not strong enough to run a house or major appliances for long. A minor annoyance, though it doesn’t affect the function of the solar power station very much, is that of the display screen.
The display screen doesn’t stay on, and there is no button to turn it on. This is a common complaint on many solar generators. Though they have nice display screens, they won’t stay turned on, and it makes it very difficult for the user to see what’s going on with their generator.

The inverter is not quite as efficient as desired, running a little low at about 75% efficiency at a 1c rate (1c rate meaning it is running at the capacity that it is rated as, or full capacity). Were it to be run with a lighter load it would be more efficient, but it’s important to know just how much a generator can handle before you decide what to buy (or what not to buy).
Two other units that are similar in size and capability to the Bluetti EB70S are the EcoFlow River Max and the Jackery 500. Both are midsize solar generators, good for portability like the Bluetti EB70S, but neither has the charging speed, number of ports, or lifespan of the Bluetti EB70S.
With a 200 W solar input capacity, the Bluetti EB70S has the same solar input capacity as the EcoFlow River Max (which can take 200 W), but more than the Jackery 500 and most other solar generators similar in size and capacity. The two 100 W type-C PD ports are unique to this solar generator, with the only comparable being the EcoFlow River Max, which has one, and the identical BougeRV 716wh, which has two.
The two ports allow the Bluetti EB70S to be more efficient in charging small devices, whereas the other comparable solar generators have both less charging speed and less capacity for charging things like cell phones and other small devices.
The Bluetti EB70S is currently available and in stock ready to ship. Though it is similar to the EcoFlow River Max and the Jackery, the Bluetti EB70S will last significantly longer due to the LiFePO4 battery, rather than the Lithium NMC batteries of the EcoFlow River Max and the Jackery.
For a comparative price, the Bluetti EB70S will last 2,500 cycles more than the EcoFlow River Max (rated at 500 cycles), and 2,500 more cycles than the Jackery 500 (also rated at 500 cycles), which is particularly useful if you are an avid traveler in need of constant portable energy, as this means you will not have to replace your solar generator for quite some time, making it a more cost-efficient choice.
Though the EcoFlow River Max has the capability to take the same amount of solar power at 200 W, the Bluetti EB70S has a battery that will long outlast it. With more ports and more cycles, the Bluetti EB70S seems to be a more utilitarian choice, allowing for longer life and more versatile use than the competition for a portable solar generator. While not ideal for powering a house or being the sole source of power in an emergency, the Bluetti EB70S is a great choice for on-the-go and portable use.
