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

I like this for not being too expansive. Worked well in my initial testing. It can hold battery and charge phone and small appliances. Also has lights which is very helpful. All in all I prefer this over gas powered ones , since I just need to keep it charged. I think the money worth it , very portable ,.light in size and with many fe as tires such as USB ports and conventional ports.

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.

Used it on a weekend camping trip to power my cpap. It ran it all night with 5% battery remaining in the morning. It charged back to 100% on a solar charger on a cloudy day, and powered the cpap again that night. Based on 1 weekend with this, I would recommend it.

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.

This item was perfect for our Cub Scout camping adventures! We charged it over night before heading out and the battery lasted far beyond our expectations! It was able to recharge several of our lights, and Mobile devices as well as our son’s Nintendo switch! About 3 families used our power bank due to theirs malfunctioning! The size was perfect for traveling and overall very easy to use. We did have a little trouble figuring out the wireless charging. But that might be due to the camera on our phones sticking out causing a gap between the pad and the back of the phone. Definitely defiantly recommend!!!!

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.]

My initial feedback is that I am very happy with this product. It is a great value at this price point. Everything works perfectly and the shipping packaging was excellent to protect the unit. If the product holds up with time, and I bet it will, this is an excellent solution for many situations.
