Hi,
Has anyone here given any thought to creating a power supply for a Tablet computer?
What i mean by power supply is an external battery with a conditioned output like say 5v at 2 amps. That's a good starting point i think. We would want a battery with high capacity like 7AHr or better i think.
One idea would be a 6v battery with a linear 5v, 2 amp regulator, but we might want to add extra over voltage protection and possibly other stuff to protect the valuable Tablet computer we will be powering with it.
Another idea would be a 12v battery (can use the car cigar lighter plug too this way) and a buck converter that puts out 5v at 2 amps, or maybe 6v and then followed by a linear regulator.
More ideas or even some circuits?
