Works well, but didn't use at first due to fear of shorting by having it set onto something as there is no bottom cover. I created a 3D Printed to protect the bottom of the board. Linked Here: https://www.printables.com/model/629635-icstation-4x-18650-power-board-cover-gy19481 There are a couple Cons: There is no mention of what the Mode switch does and I haven't been able to figure it out. The unit does charge a client device while charging itself, but once charging power is removed, the device resets the output, so couldn't be used as a battery backup.
