Why Won't My Zephyr S3 Charge with the ETENWOLF 30W USB-C Fast Wall Charger?

Updated on Oct 22, 2026

Q: Why Won't My Zephyr S3 Charge with the ETENWOLF 30W USB-C Fast Wall Charger?

A: The ETENWOLF Zephyr S3 has two ports on the back:

  • USB-C Port (Input): Used to recharge the Zephyr S3.

  • USB-A Port (Output): Used to charge other devices, allowing the S3 to function as an emergency power bank.

The Zephyr S3 does not include a wall charger. It comes with a USB-A to USB-C cable, which can be used to charge the S3 with a USB-A wall adapter or to charge other devices through the S3's USB-A output port.

Why isn't it charging?

The ETENWOLF 30W USB-C Fast Wall Charger has a USB-C output port. If you connect the included USB-A to USB-C cable with the USB-A end plugged into the S3's USB-A output port, the S3 will not charge.

How to charge your S3 correctly:

To use the ETENWOLF 30W USB-C Fast Wall Charger, you will need a separate USB-C to USB-C cable. Connect one end to the charger's USB-C port and the other end to the S3's USB-C input port.

Alternatively, you can use the included USB-A to USB-C cable with a compatible USB-A wall charger.
