GRECELL-4000W Portable Power Station 5040Wh Solar Generator with LiFePO4 Battery 6 AC Outlets 7000W Peak 1 5H Fast

For it's size, this power station is impressive. It came already charged at about 80%, so I plugged it in to fill it up. I don't recall how it long it took, but it wasn't too bad. I tested it out to see how quickly it would charge my cell phone, and it went from under 80% to 100% in about thirty minutes, which is nice, and only lost 1%. Theres only one AC port, three USB A ports that use quick charge 3.0, and one PD 60W USB C port. It's compact and not as heavy as I expected, which makes it super portable and easy to carry around. I appreciate the accessories, which include a charging cord, a lighter cord to charge it from the car, and a third one that I'm not sure of. It might be the one to connect the optional solar panel. It's listed in the manual as an included accessory, but it doesn't say what it's used for. It comes with a storage bag for all the cords and manual, which is a nice addition. The flashlight is bright, and I can see it being handy in a blackout. My plan is to use this to keep my router going when we lose power, which happens more often than it should. I have a UPS strip currently, however it's noticeably declining in lifespan, so this station will be helpful in extending the time I can keep the internet alive at home. Read more

It’s lightweight, easy to carry, and the screen makes it simple to check power levels. Not strong enough for big appliances, but perfect for lights, fans, and electronics. Read more

I've been a huge fan of GRECELL ever since I bought their smaller 240W portable power station, which has been incredibly reliable. So when I needed a larger unit for my longer camping trips, I didn't hesitate to go with the GRECELL 300W model. This power station has quickly become one of the best pieces of gear I own. The 288Wh capacity is more than enough to keep all my devices charged. I've used it to power everything from my phone and tablet to my drone and even a small mini-fridge. The 60W USB-C PD port is a huge bonus, as it charges my laptop incredibly fast. I also love that it has a pure sine wave AC outlet, which is crucial for sensitive electronics. It's surprisingly lightweight, very quiet, and just works exactly as advertised. If you had a good experience with one of their smaller units, you won't be disappointed with this one. Read more

The media could not be loaded.

The pure sine wave AC output at 110V ensures clean and stable power for sensitive devices, a big plus over modified sine wave alternatives. Weighing just about 8 lbs, it's lightweight and easy to carry with a sturdy top handle. The build feels durable, and the control panel with LCD display is intuitive and easy to read showing battery level, input/output wattage, and status icons.
