  • Charge two iPhones at once with 4.8A total output
  • Single port delivers up to 2.4A for faster charging
  • MFi certified coiled cable extends to 6FT
  • Smart chip protects against overvoltage and overcurrent
  • Temperature sensor adjusts power to prevent overheating

Dual USB car charger with coiled Lightning cable

The Caiinei 4.8A adapter plugs into a cigarette lighter socket and supplies two USB-A ports for simultaneous charging. A built-in MFi certified coiled Lightning cable reaches 6 ft when stretched and retracts to roughly 1.3 ft for tidy storage. Compatible iPhone models range from the iPhone 5 through the iPhone 14 series plus iPad and AirPods devices.

Practical limits of the USB-A interface

Each port can deliver up to 2.4 A or 12 W when used alone, while both ports together share a 4.8 A or 24 W total. The USB-A connection caps output at these levels, so devices that support higher USB-PD rates will not reach their maximum speed. The coiled cable adds resistance at full extension, which can slightly reduce voltage at the device end.

Replaces separate chargers and loose cables

This unit combines a dual-port charger and a certified Lightning cable in one package, removing the need to carry a separate cable for each device. The upgrade is worthwhile when you regularly charge two Apple devices in the vehicle and want a retractable cable that stays organised. Buyers who need USB-C connectivity or higher single-port wattage for newer iPhone models should look elsewhere.

Questions about this item

Should I pick the single-port 2.4A mode or the dual-port 4.8A mode?

One port alone delivers up to 2.4A at 12W; plugging in two devices splits the 4.8A total so each gets up to 2.4A simultaneously.

What does the 4.8A rating actually give me in the car?

It supplies a combined 24W across both USB sockets, enough to fast-charge two iPhones or an iPhone and an iPad at the same time.

How does the built-in Lightning cable handle the 2.4A per port limit?

The MFi-certified coiled cable uses a C89 terminal and 56 kΩ pull-up resistor to negotiate the correct voltage and current for each connected iPhone or iPad.
