    I’ve used this 2x for camping. Has worked pretty well so far. Not many options for power banks in Hawaii. The screen comes in handy. It tells you battery percentage, how many watts is being consumed, etc. I wish it said how many mAh it was though.

    The USB-C port does not work. The two normal plugins, that are one on top of the other, are too close together to use both at the same time. Best Buy would not take it back, then I contacted the company to get warranty work done, because Best Buy told me it has a one year warranty. They never contacted me back, and I attempted multiple times through e-mail and by phone.

    SLOW charging and NOT inverter output!

    I tested this unit at 210Wh, which is pretty decent for the advertised ~275Wh rating. The charging speed is dead slow at 5 hours. Unfortunately this unit also seems to be a square wave output which will DAMAGE your sensitive electronics devices. I’m going to be returning it. I cannot recommend this unit based on the slow charge speed and nasty square wave output for this price. I’m going to buy a.man Ecoflow River Pro for 3X the capacity and only 2X the size.

    charge adapter sux, off the shelf generic straight in easy to break off or damage the internals of the device. USB-c is fine but takes the better part of forever to charge. I would've liked to be able to charge with one of my solar panels but the inputs are limited to AC with awful included brick or USB-C

    I had a power outage, and I used this thing to help keep my refrigerator working. Right after I plugged it in, it immediately drained the battery down to 70%. Use only to charge cell phones and small electronics.

    Haven't needed it yet, but I did test it out. I wanted to see if it would power our recliners, as being senior citizens, when the power goes out, and the chairs are extended, it is hell trying to get in or out of them. It probably is funny to watch. Also, I can power on my router and watch TV on my phone.
