I've had mine installed for a couple months and found that while my Galaxy S2 appears to be charging (the lightning bolt appears over the green battery indicator), the device is absolutely not being charged. Ran my phone completely down one afternoon after a full charge in the AM. I was using GPS like I use when it is plugged into my car's 12v adapter, which does keep the device charged.
Socket is wired directly to battery with the included fuse.
