200W Portable Power Station, FlashFish 40800mAh Solar Generator With 110V AC Outlet/2 DC Ports/3 USB Ports, Backup Battery Pack Power Supply for CPAP Outdoor Advanture Load Trip Camping Emergency.

I was supprised with how small this battery is. The whole thing is less than the size of a shoe box and comes with several accessories including a USB light, a way to charge via wall outlet (AC) and a way to charge via car (12v DC).It doesn’t have a built in DC/cigarette lighter style outlet for 12v appliances but it does have an adapter which you could then plug a splitter into it. It came fully charged which was a nice touch. The instruction manual says it will hold a full charge for about 3months.Recharging does take a long time (all night when plugged into the wall. Probably longer if plugged into a solar panel or car)It has a helpful built in display which shows battery life. There are 5bars and each bar represents approximately 20% battery life. So you can really know how much you have left.Everybody always wants to know what real world battery life will be so I ran some tests. My purpose for this was not to use with solar panels, but just to keep charged in case of power outages, I would be able to charge my phone, maybe watch a movie on my iPad, and most importantly to run a fan so I don’t die of heat.Test 1: ran a big box fan on high, phone charging, iPad charging, USB light. Battery life was about 100minTest 2: medium size table fan plus phone charging. Battery life was about 3hrsTest 3: ran only a DC fan (the kind you see on school buses and mail jeeps) it was powerful enough to really blow but just sipped power. This ran on high for 12hrs and still had over 20% battery left.Test 4: just for kicks, I tried plugging it into a fridge (both full size and dorm size). Unfortunately, the surge was too much and it couldn’t run it at all. This was about what I expected.Overall, I’m very happy with this product, especially for the price. I wasn’t able to find anything bigger that didn’t jump tremendously in price
