MATRIX™ 5,000mAh Solar Portable Power Bank with Dual-USB and Flashlight (Green)

I buy a lot of power banks to test. This worked really great at first. I had watched this review while it was still working great.[...]. Today I experienced similar problems as the YouTube review. The lights started flashing. The LED turned on and wouldn't switch off. The circuit started smoking. Left with no other choice I opened the unit to cut the battery from the circuit to prevent a lipo battery explosion. It was a bit dicey. This I'm sure voided the return policy which was up a few days ago anyways. This has been one of the most disappointing purchases on Amazon. After opening it, it's obvious to me that it has nowhere close to the capacity it promises and the solar panel is nothing more than decoration. Do not buy. This little thing could burn down your house.

This has stopped working after 1 charge :(
