I was not expecting much for $1 plus $2.59 S&H from Hong Kong.
It is smaller than I expected. Must lose size in the SAE-Metric conversion? LOL
Listed on eBay as 0.4W, 5.1V output, USB 2.0,
"Work for MP3 MP4 players or cell phones with 3.6V build-in rechargeable battery".
The little bugger is impressive.
The wife's MP3 players charge in the car during use, but they power up and say "Full charged".
The Garmin Edge 305 GPS charges fine.
Motorola BlueTooth ear piece charges fine too.
That is all I could find here to connect it too.
Looks like it would work with anything that charges from USB 2.0.
It even charges (some) behind double pane window, with a screen, in slightly overcast conditions.
I would not call it rugged, but more than adequate for the intended purpose. It should be fine in a glove box, purse, or jacket pocket.

Nice to see something like this for a good price.
