Voltix デュアルUSBカー充電器 3V（ポートあたり1.5V）- グリーン

Forget the backseat drama—this charger keeps both kids’ tablets juiced up on road trips with no arguments. The dual 1.5V ports are perfect for their needs, and the green color makes it easy to spot in the dark car. It’s small but sturdy, so it doesn’t stick out awkwardly from the lighter socket.

I plugged this into my car's lighter port and both kids charged their tablets at the same time without any arguing—the 1.5V per port is exactly what they needed. It's compact and fits flush in the socket, so I don't worry about it getting knocked loose on bumpy roads.

The green color makes it easy to spot in the dark glovebox, and the dual ports finally end the backseat squabbling. It's a bit bulkier than I'd like, but it charges both phones steadily enough for the price.
