Griffin PowerJolt 後部座席用カー充電器

Took this on a road trip with the kids and the dual ports meant both tablets stayed charged the whole way, no fighting over who got to plug in first. The cable length reaches the back row easily, which saved us from a lot of whining.

Installed it in my backseat outlet last week and forgot it was there until a friend needed a charge — that’s how unobtrusive it is. The two USB ports handled my phone and her tablet at once without any slowdown.

Took this on a road trip with two kids in the backseat, and the dual USB ports meant both tablets stayed charged the whole six hours without anyone fighting over the outlet. It’s been in the car for three weeks now and the fit in the 12V socket is still snug, no rattling over bumps.
