Customer Ratings & Reviews

Super compact & light. Great product for every man who’s going to go to the camping or wilderness. To charge my old iPhone 12 Pro you use 3-5% battery per 1 charging. Immediately charging on 100W solar panel exposed on Californian sun in September.

Good product, does what I need it to do. Bought it for a battery backup during our Florida storms. I haven’t had a chance to test it out yet but it charged quickly. Less than an hour from the ac outlet. There is only one outlet on this model, so I’ll have to use a power strip to run more than one thing at a time. But it also has 2 type A usb ports for charging phones or other tech. It can be charged through your vehicle power outlet as well, just don’t try it without the engine running or it will drain your battery. It comes with the cable for charging from the car and the wall ac. I have a solar panel to hook up to it soon so I can run the lights and a fan in my shed and charge my batteries. That requires me to purchase a cable, they are easy to find on line and pretty cheap, but which one you get is determined by the connector on the solar panel you have.It is smaller than I expected, about the size of a child’s lunch box. And the li-on batteries make it very light, so I can keep it hooked up to the solar panel for my shed and bring it in the house to run lights and fans during storms, or put a mini fridge in the shed and use it with the solar panels to keep some of my food cold after the hurricanes. Either way it will be a very useful purchase.

Glad I picked up the Jackery because it provided so much power at our popup tent event. Our event lasted from early morning to the evening when it was dark. It powered my register, string lights, charge card swiper, and all our phones and still had a lot of battery left! So concenient and powerful. We didnt have to stress about power.

I do a lot of outdoor markets and need to set up my tent with lights. This will keep them powered the whole day, plus I am able to charge my phones. I would definitely recommend!

This is my second Jackery, cuz I love it so much! Our power goes out frequently, and it is perfect for when you want to power a few things without turning on the generator. Also good for when you are away from the house and need power.

Provides enough power for laptop and other small electronics. Small enough to be portable and convenient to travel with in the car so we can work during road trips. Plus, we got it on sale!

I use it every weekend when I hunt and it’ll never drop below 60%. Great battery back and would recommend

Nice, solid design. Not sure why they call it a Solar Generator though - it's just a battery pack with outlets and an inverter. I guess you can get a solar panel to charge it with, but I would only do that if I were going to be camping where there isn't an electrical outlet to use to charge. I think it will serve my purpose very well - to power a telescope tracking mount. I got what I think is a really good price, but if I had thought about it/read up a little more, it probably would have been better to get the newer model that uses the Fe battery since they seem to last longer. The standard Li-ion battery will probably last me a few years, though.

I got this item due to worry about the hot summer weather approaching in 2022 in the Northeast USA. I do have smaller portable power banks, but I wanted something that could use solar panels as an option in an emergency. A warning about the shipping. This Jackery was not available for local pickup. Only shipping was available. I received the item in a poorly packed, beat-up, rain-soaked cardboard box. The shipping box had way too much open space; so it was sliding around in transport. I can see large curved indentations where the empty space gave way to heavier stacked items. Best Buy sure has untrained and inept packers and shippers for their items. If this were a fragile laptop, I would have immediately shipped it back and got a full refund. At least the retail packaging actually have custom shaped foam in its own box that protected the Jackery. The Jackery 290 is small and not very heavy. I tested the AC port and the two USB connections simultaneously with and iPad and two smartphones. The iPad power adapter felt warm in the AC adapter. All three devices were drawing 30 W of power. The LCD display is simple, yet informative. I don't need those colorful displays that would even use more power. I did not test the 12V port. This port does not have a dust cover, so take care not to get dust inside it. I tested charging this unit via the included 65W AC adapter. Be aware that the AC brick is extremely hot while charging. You should not leave this unattended charging near flammable items. It took about four hours to charge from 38% to 100% via the AC adapter using 61 W of power. I noticed the input was dropping from almost to zero watts as the Jackery went from 99 to 100 percent. This is a good safety feature. I will store this for three months and take it back out to see how much power has been lost.

Great portable battery. Got a 100w solar panel too and it is fun to optimize my daily electricity use. The battery feels sturdy and is easy to use.

Took this camping and it was great! Lasted the whole 4 day trip and still had some. Used it for phones, mattress blowers, tablets, small cooler

We have taken this camping a couple of times and we can run a box fan on it for the majority of the night, which is the main intention.

If you're looking for a reliable, high-performance portable charger, the Jackery is a game-changer. I’ve used it during power outages, and it’s never let me down. Thumbs up!

This is not going to keep you warm in a storm or keep your refrigerator on for any length of time. However, its great for short amounts of time, and recharging phones. A tiny 120v heater ran for 2 hours or so with this generator fully charged.

This little powerhouse kept my multicolored camp tent lights going all night long, and still had juice for my phone charging, and air up air mattresses with pump. Amazing little tool. I actually plugged in 2 box fans and was only at 150watts (75watts x's 2 fans). I almost bought a second one. Will look into a solar panel as a next purchase.

We just took it on our trip to Disneyland since my dad just finished cancer treatments and needed to take a mobility scooter. It fit nicely in the little locked storage box on the back and came in so handy - we charged our cell phones on it and then at lunch he charged up the scooter. It gave it a nice charge to finish the day. Very convenient.

GREAT UNIT - highly recommend. Small but powerful

Exactly what I needed -- just in case I lose power, I can still keep a few things on such as light, cell phone and laptop.

Works. Weight: light enough for this arthritic old lady to carry, Only negative so far: like so many products, for some reason they make the on/off/control buttons the same color as the background (black on black) making it hard to see where those buttons are, improve by making it easier to see these buttons.

It is a great product to use to travel. Especially for camping
