Hope someone may help with such a problem: I am looking for a power connector, to connect my 12v battery operating device to the charger. Barrel connectors are way way too big - the size is of a paramount importance. Micro USB seems fine, but it is too wide-spread and since I have 12v there is a chance of a user to miss-plug it and fry some phone or laptop, which is not nice. Perhaps anybody knows, where there is some small connector, durable, with about contacts, suitable as a charging interface?
Thank you all!
And happy coming Thanksgiving!
