standard usb doesn't deliver enough power to charge large tablet batteries in reasonable time. the nook color has a mini usb power port but the nook color charger is extended with extra pins to charge at ~2000 mah.
- nl 16y agoThe obvious response is that it should offer dual USB ports for charging. It would be pretty easy to design a connector with two (mini|micro)usb male connectors on top of each other. Then you could trickle-charge to a single port from a normal USB connector and charge properly from the double-connector.
- nazgulnarsil 16y agoI believe 2000mah charging would require four usb ports
- nicpottier 16y agoTne Nook's solution is the right one. I assume you can still charge, albeit at a slower rate, using a standard mini usb cord from a computer then? Slow charging is better than no charging, being able to just use good old USB when the need arises is key for any mobile device. I just refuse to buy anything anymore that doesn't charge from micro or mini-usb. I wish Canon would get on the bandwagon and allow recharging of their cameras in the same way.
