Project creators/managers need to inform backers regularly (at least a paragraph a week - if that is too hard then maybe McD can use another manager/burger fipper).
@Creator: I speculate that the function of vampire proofing may have eluded one of us.
A charging circuit (like a transformer or "wall wart") will draw power at all times despite what is plugged into its output unless there is a circuit that prevents this from occurring. So, unless your system does not use a "power adapter" to gain its charge - or you are not providing that power adapter then this is a problem.
So, maybe I missed something... how is this device getting its input power? If it is by way of a circuit that does not have vampire proofing then it will happen. Simple logic and physics apply. If there is no drain at the output of the power adapter because the charging is done then the vampire-proof circuit reduces the power consumption of the power adapter to truly negligible as opposed to the draw that is inherent to a transformer.
As mentioned in the comments, we believe that vampire proofing is not a very good idea. Almost all Smartphone and Tablet's will stop drawing currents after they are fully charged. So it is not needed. Secondly cutting off power at that time will have undesirable side effect that device will drain battery even when it is plugged in.
Question... Will this have anti-vampire circuitry so we do not have a power drain when all the devices are charged?
Excellent! Thanks for the notification.
