Top critical review
Poor quality control at the factory.

Build quality issues, like others mentioned. Fresh out of the box, I plugged it in to charge (came with a 25% charge as expected) and 5 minutes later it stopped charging. Tried several other USB-c cords, power bricks, and it still won't indicate it is charging. After 2 hours the brick I have it plugged into is cold suggesting that the unit isn't pulling power. These things should be tested better at the factory.
When I plug in the jumper connection it says the battery has 12 volts, so the jumper part of the battery seems to have juice. I'm assuming the usb charging electronics are cheaply made. Manual is also poorly made, refers to a power button on the side that is actually a switch.
