Fervit USB 2.0 cable A male to female with power switch

SKU CH-SWEF-TH4W5

USB 2.0 A male-to-female charging cable with an inline power switch for 5 V devices up to 3 A, no data transfer

  • On/off button cuts power without unplugging, reducing USB-A port wear
  • Two-core 2.0 cable delivers up to 3 A for low-power USB devices
  • No data lines — pure 5 V charging for lamps, fans and small gadgets
  • Not compatible with high-power hosts or PD chargers, preventing overload damage
  • Male-to-female Type-A extension adds reach while keeping a simple power switch

Power-switch USB 2.0 cable

This USB 2.0 cable has a Type-A male plug on one end and a Type-A female socket on the other, with an inline push-button switch. It is designed solely for DC 5 V charging of low-power devices such as LED lamps, small fans or phone chargers, and it carries no data lines.

Charging capacity and headroom

The two-core cable is rated for up to 5 V 3 A, so it can handle small USB desk lamps, fans and similar accessories without issue. It does not support any fast-charging protocol and cannot power high-draw equipment such as laptops or be plugged directly into a Power Delivery charger.

USB 2.0 power-only limitation

Because the cable omits the data conductors, it cannot be used for file transfer, peripheral communication or any device that requires the USB 2.0 data interface. The switch simply interrupts the power path to reduce wear on the host port.
