:eek:For anyone purchasing a SPRINT BATTERY BOOST to use to charge their micro-USB phones, DO NOT TRY TO CHARGE YOUR DEVICE while the Booster is charging....it's advertised to be able to be hooked up to an electrical charge AND charge your phone simultaneously....well I tried that yesterday and nearly burned up my desk AND the booster was hot as a boiled egg after about 15 minutes....smell of burning something in the air....I unplugged EVERYTHING and let it all sit, today the booster seems to be OK with the exception of smelling like burnt transistor, LOL. I haven't tried to use the card reader yet. Just an FYI, don't do what I did you might start a fire!!!!
