Hey all
As some of you who have the new Coby gen3 tablets will have noticed; these tablets support charging through the USB port.
However, you may not have realised that charging through the USB port is not as fast as using the mains adaptor. After checking the estimated charging time with my 9742 connected to USB and then the mains adaptor, I found that the charge time was roughly double for USB charging.
I also found that having the USB cable connected to a 1A adaptor while the mains charger was plugged in also did not affect charging time.
Based on this I think we can safely assume that these tablets (at least some of the gen3) have a proper charging circuit with current limiting (at least on the USB port, I tried an iPad charger as well) that suggests to me that we can safely use mains adaptors with higher current ratings than standard.
