Not trying to diss the products on this site. Some are great, some are not. These are absolute junk. Description here do not state the power rating. Let me spell it out for you:
Input: AC110, AC10mA
Output: DC 5.0V plus-minus 0.5V; DC 300 plus-minus 30mA
Read -- 300 mA. You can forget about powering anything with these. I've tried ALL of my USB-powered devices and these do not work! Products tried: Moto RAZR V3 (charging fails), Blackberry Pearl (charging fails), Sandisk Sansa (thumb-drive sized MP3 player - charging fails). Most USB devices nowadays require at least 500mA to operate. I finally bought one that outputs 1000mA and THAT started charging my RAZR, Pearl, and some other stuff.
