Is the only way to optimize the charging hub, must you use their car charger unit or is there one out there with the same output that there charger gives...?
Gigs_is_90xIf you are looking to charge in your car or mobile vehicle, the recommended car charger is the Vehicle Power Cable for ChargeHub, as it meets the necessary specifications. If you can find another car cable that has those same specifications and barrel connector dimensions, then that may work, but is not reccomended.
