GRECELL Portable Power Station 300W, 230Wh LiFePO4 (LFP) Battery, 1.5hrs Fast Charging, 2 Up to 300W(Peak 600W) AC Outlets, Solar Generator for Outdoor Camping/RVs/Home Use

So far so good! It charges your phone, you can plug a lamp or plug any number of things into it to charge or just run, and it just works. I'm very happy with my purchase, so happy I bought a second one with a solar panel for each. It's easy to use, just push the power button and plug a device into one of the USB ports or outlets. You can also wirelessly charge your phone on the top pad. Awesome battery for the money. It's not heavy at all so it's easy to carry.

Original review: Fresh out of the box, it only charges to 92% using the charger it shipped with. No errors on the screen. Tried usb-c charging as well. No fan running and it’s cool to the touch (indoors). No solution in the manual. Can’t figure it out. Other than that, looks and seems like a pretty nice unit that checks all the boxes. I ordered a second one to see if maybe this first unit is just a dud. Will update the review with my findings. Update 1: Fantastic documentation! Can’t say enough great things about the specifications and documentation. Very impressed! Unit 1 definitely has some display issues because the charge level indicator and output indicators are off. For example, it will say 120 watt output and the receiving device will show 140 watt in. Unit 2 seems perfect so far. Love the pass thru charging! I wish it shipped with a 100 watt charger and a 100 watt usb-c cable, but that’s a minor gripe. Very happy! Update 2: After conversing with the seller, we figured out that if I drain it 100% to 0%, then fully charge immediately to 100%, the gauge will reset. Now both units seem to charge and work identically, and I can no longer determine which is which. Paired with a 130w dell DC7455 plug size charger, it charges at ~99w on ac alone, and can be plugged into USB-C charger to charge even quicker if needed. I drain them both daily and am extremely happy. Debating on getting a 3rd. Compared to others, it is a fantastic sweet spot of a deal. DC Input DC7455 ; DC Output DC5521; Recommend getting the 130w dell or greater charger as the 90w dell one tends to over heat and shuts down after an hour because this battery will pull 96w from it. That’s a good thing on both sides. Very happy! Update 3: Many months later…I now own 4 of these, one permanently charging from 100w solar (~70w input according to battery), one as a battery backup for a computer (on a cheap outlet timer to make sure the battery gets a workout daily), and two others floating around. I can’t say enough great things about them. I encouraged my family members to buy them as well, and they use them from camping, remote working and etc. These are simple, well built, hardworking and the price point is perfect. [I wasn’t paid to say this.]

Great little power station. I bought this due to the approaching blizzard (which we're going through right now) to have on hand to have emergency power for lighting, charging my phone and tablets, and other things I may need power for. The power station is powering the light pole which has 0.5w C7 Candelabra LED Light Bulbs installed (shown in this review). These bulbs are brighter than the incandescent bulbs that was installed, and much more energy efficient. This power station is so good, that iI calculated that it could power those three lights for almost 2 weeks nonstop. As I do not have a phone to use the top charger, I cannot test that, but I get good results with the USB DC ports. And on sale for $99.99, this is a steal. You will thank yourself for getting this. If the power goes out and you cannot install a whole house generator where you live, this will certainly suffice.

Works well for general use. Didn’t work for I bought it for which was a small space heater and it takes a while to fully charge it. Now it’s just a backup power supply in case we lose power.

Great little power station, powers my router so I can use my free Wi-Fi, and my laptop during power outages. It's lite weight, and fits just about anywhere. The EB300 blows up air mattresses with ease, and even has wireless phone charging!
