There seem to be quite a few of this style of camping light being sold. Here's my latest find, and rather predictably it has the same dodgy mains-referenced USB connector. This unit is a hybrid of the other two in that it offers the same flashlight function as the gold one with the same area light assembly as the red one.
In this video I also show how to make a crude USB powered charging circuit to replace the dodgy capacitive dropper based one. It's not ideal, but it's better than being fried by your iPhone when you plug it or any other metal bodied USB device into the port of this light while it's plugged into a wall outlet. An improvement would be to use a Schottky diode with a slightly lower forward voltage drop than the silicon diode I used.
