Recently, JOYROOM launched a new coiled car charger with the spring cable, which features fast charging, multiple devices, integrated cable and others.

The new JOYROOM coiled car charger has two parts: the car charger and the spring cable. The car charger is made of PC flame retardant, and the shell is printed with the "60W".  The spring cable makes it more convenient to use.

The car charger adopts two USB-A ports and one USB-C port, with its own spring cable, namely the second USB-C port.

The spring cable and USB-C port are separate, all supporting 30W fast charging and 30W + 30W simultaneous fast charging.  QC3.0 1/2 ports share the same circuit. When used alone, they all support 18W multi-protocol fast charging.

Here is the 0.4 m integrated spring cable.

The spring cable is 1.6 meters long when stretched, and it has a USB-C port.

The positive pogo pin on the bottom and the negative pogo pins on both sides make the car charger not slide out when driving, ensuring the stability of the power supply.

There is a circle of colorful LED light around the edge of the front.

The POWER-Z KM002C USB tester shows that under 12V, the spring cable USB-C port supports three fixed PDOs of 5V3A / 9V3A / 12V2.5A and one PPS of 3.3-11V3A. Another USB-C port on the car charger is the same as on the spring cable.

Under 24V, the two USB-C ports support five fixed PDOs of 5V3A / 9V3A / 12V2.5A / 15V2A / 20V1.5A and two PPS of 3.3-11V3A / 3.3-16V2A.

In addition to the USB PD fast charging, it also supports APPLE2.4A, QC3.0, QC2.0, FCP, AFC and other fast charging protocols.

Charging Test

The car charger supports 30W PD fast charging. The USB-C port is tested to support 9V PDO when charging the iPhone 13 Pro Max with the maximum power of 9.06V 2.92A 26.55W.

Under 24V, the USB-C port supports 15V PDO with the power of 14.97V 1.72A 25.88W when charging iPad Air.

Under 24V, the USB-C port supports 20V PDO with the power of 20.08V 1.44A 29W when charging Macbook Pro.

When charging two devices simultaneously with the USB-C port and spring cable, the power reaches 8.88V 1.42A 12.62W / 8.42V 2.14A 18.09W respectively, both in fast charging. It can charge up to four devices at the same time, and it is in 5V4A output.
