GRECELL Portable Power Station 300W, 288Wh Lithium Battery, 60W Fast Charging, Up to 300W(Peak 600W) AC Outlets, Solar Generator for Outdoor Camping RVs Home Use

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.]

Works great! I haven't used it alot as I just got it a couple of weeks ago, but so far I have run my home fridge/freezer with it. Power station was at 50% after 12 hrs. Also ran my washing machine off it. Ran a regular cycle and had 91% left. Im pleased. I feel like its a great addition to the backup gear at home. And it arrived well in advance of the estimated arrival date.

It's a great little generator for small stuff. I've been testing it on different things. It can't run a coffee pot or hot water kettle. But it can charge your phone, wireless ear buds / airpod and at the time of me typing this review, I have both plugged in to the generator. The generator is at 39% battery life and still have enough to charge both those items for 17 hours! Only takes less than an hour to charge my android phone so I know i won't run out of battery life for it soon. When the generator is at full charge, I have observed it can charge my phone and run a box fan for 4 hours. I haven't tried it with the solar panel yet. Will edit this review when I do. Instructions were simple and there's no noise at all coming from the generator. It's lightweight too.

I purchased this before a predicted ice storm. No generator, so i at least wanted my phone to work. Took a while to charge, and it never got beyond 99%, but after a couple of weeks, it has maintained that charge. Haven't tested it on my phone yet, but will update review when I do. Price was affordable for what it offers. I'll eventually get one with the capability to keep my router and wifi running, or power a coffee maker.

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.

Excellent power supply, and great value considering it was also of the better, safer LiFePo chemistry. Packaged better, more smartly than other powersupplies I've tried. Pure sign wave AC runs my sensitive electronics (behringer mixer, Shure wireless mics, minifridge without a problem and without a hum. Charges fast.

It has 1200W of power and a 672Wh LiFePO4 battery that offers very good performance and longer useful life. I have used it as a backup at home and it works excellently to keep essential equipment connected.

Well, do you feel lucky? I purchased a GRECELL Portable Power Station 600W which failed to operate properly (12VDC section would not turn on) 3 days after the Amazon 30 day return policy ran out. Working with Amazon customer support was unfruitful. GRECELL was totally unresponsive. So now I have a $300+ portable phone charger.
