We continually make minor tweaks to the USB output of our batteries to make sure we charge as many devices as possible. We pay particular attention to Apple products and now, with the introduction of the iPad, it has become slightly more complicated to have a one size fits all solution. This post tells you the Voltage on each pin of our USB batteries, which is hopefully useful if you’re trying to make your own USB charger.
There are lots of different threads Apple charging, but we’re going to focus here on USB pin Voltages as this was the variable we were adjusting in this round of production.
