Universal vehicle charging

The CyberPower CPTDC2U is a 12 V car charger with two USB ports rated at 2.1 A each. It suits drivers who need to power tablets and smartphones simultaneously while on the road.

Input range and port limits

The unit accepts 10.5 V to 15.5 V DC from a standard 12 V accessory socket and draws up to 15 A maximum. Each port delivers 5 V at 2.1 A, so devices requiring higher current will not charge at full speed.

Compact build and daily use

A black cylindrical body measuring 3.189" by 1.22" by 1.22" and weighing 0.055 lb fits flush in most sockets without blocking adjacent controls. An LED power indicator confirms the circuit is live, and the dual-port layout lets passengers charge two devices without a separate hub.

Questions about this item

Should I pick a charger with one port or two ports for my phone and tablet?

This model has two USB ports, each delivering up to 2.1A, so you can charge a phone and a tablet at the same time without choosing between them.

What does the 2.1A rating actually give me when I plug in my iPad?

The 2.1A output at 5V DC provides enough current for fast charging on tablets and smartphones, including iPad, iPhone, Android and BlackBerry devices.

Will it work from my car's 12V socket and what limits the power?

It plugs into a 12V DC auto power port and accepts 10.5Vdc to 15.5Vdc input up to 15A, so the vehicle socket and fuse determine the practical ceiling.
