Thanks for the answers - I think the point about needing to rapidly discharge power and this probably causing overheating is a good one. Food for thought
Hi,
Does anyone know if (in theory) it would be possible to link two iPhones together by a small cable and share power between the two? i.e if the battery is flat on one and full on the other is it possible for one of the phones to "give" power to the other? The process of how much you share...
