The $7.99 wall wort showed up last night (thanks Amazon prime). The power plug is the correct size for the power tap and it seems to fit the TorchLED bolt very well. Everything powers up and I left the TorchLED on for about an hour to make sure the little power supply could keep up.
The only issue I have with the little $7.99 wall wort is that the cable is supposed to be 5.5 feet long. The unit that showed up has a cable length of a little less then 4 feet. Either way, you’re going to need an extension cord, but it would have been nice if you got what was advertised.
