Please forgive me if this is a dumb question. I did some poking around the forum and didn't find a specific answer to my question. I have an iTaste MVP 2.0 and the manual says to stick to chargers that output 5v 500mA. I have several micro USB chargers which are either 5v 1A or 5.1v 680mA. Will neither of these work? I'm just wondering if I need to go out and buy yet another wall wart for travel. Thanks in advance for any help!
