Review on TPF Charger Utra Fast Universal Charging Car Electronics & Accessories by Daniel Pierce

Looks like a good product? But "looks like" because I haven't had a chance to try it yet. The first battery pack purchased has a side connector with 2 reverse connectors. One connector is round and the other half square with the square half of the second connector facing in between them. . This socket adapter is what seems to be the more common "flat end out" arrangement. The first battery seemed unusual to me and was sent back. So I looked much more carefully for a battery that physically matches the connection AND doesn't warn against using the launcher connection for anything other than jump-starting. So the final assessment is still pending. Does anyone know of a good quality battery that will allow you to plug your device in via a jumper and ship it to Hawaii?
