Are there design issues with tablets being charged by USB not seen with Android phones?
I saw this on another forum, what are your thoughts on this with regard to my question? http://forums.androidcentral.com/acer-iconia-a100/112270-charge-via-usb-port.html#post1696260
An important consideration in the design is the amount of current the usb connectors can handle. I figure the designers find that it is safer to design a separate charging and power connector because as the devices get larger they draw more current to operate and charge the battery. I think that is the reason they do that. Is there no 12 volt adapter for these devices? I don't own one yet, just leaning towards the acer 7 inch tablet.
I would prefer charging via USB (via mains or PC) when considering a tablet so that I don't have to carry around a specific charger.
Many Android phones use their micro USB port for charging - connecting the USB cable to a mains adapter or using the cable to connect to a full size USB port on a computer.
I see that some major brand Android tablet manufacturers (Motorola, Asus) as well as some smaller less know brands either use a separate power input (non micro-USB) or a dock.
