Could someone explain USB chargers / specs to me. We seem to have an ever growing selection of devices that charge via USB, some of which have mains chargers. I understand the difference between the connectors, what I'm struggling with is ampage rating. If I use a mains USB plug rated at 1000mA with something that requires 100mA is it going to melt or does the main charger regulate the current required. Does it depend on the mains charger.
I need one charger unit I can take to the States that will charge mobile phones (HTC & Blackberry), Kindles, a GoPro and a couple of DS's and I don't want to take all the chargers & leads they came with plus a laptop just to top up the batteries.
