GRECELL Portable Power Station 300W (Peak 600W),GRECELL 288Wh Solar Generator with 60W USB-C PD Output, 110V Pure Sine Wave AC Outlet Backup Lithium Battery for Outdoors Camping Travel RVs

Small, but powerful
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.

Surprisingly Powerful for the Size
I bought this GRECELL 300W for camping and it works better than I expected. It’s small, easy to carry, and the battery lasts long enough to charge my phone, iPad, and run a small fan. The 60W USB-C port charges my laptop fast, and the AC outlet is stable with no weird noise. I also tried it with a solar panel and it recharges fine. Overall, a solid, reliable backup power source for the price.

GRECELL Does It Again! A Must-Have for Any Outdoor Adventure
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.

Powerful and reliable
This unit delivers a steady 300W continuous output, with a 600W surge capacity, making it ideal for powering small electronics like laptops, tv, mini fridges, CPAP machines, drones, and even low-wattage cooking devices.

It’s especially useful for camping, tailgating, or emergency home backup during outages. While it won’t run large appliances, it’s more than capable for powering essentials and keeping your devices charged and connected.

I tested it out and it works for my coffee machine, which I wanted. I am sure it will work with other things too.

I have owned other large brands of power supplies and this one is the best. You can’t be at the price and it’s never let me down. It’s actually running my entire camper van that I live in full time. Absolutely love it!

I was very impressed by this. It lasted a long time, and recharged quickly.
