Vszerda 30cm USB cable with ON/OFF switch

SKU CH-NGRW-NM6S0

A 30 cm USB cable with an integrated on/off switch for powering lamps, fans or other USB devices

  • Convenient power control with integrated ON/OFF switch
  • Compact 30cm length reduces cable clutter on desk
  • Powers USB lamps and fans directly from any port
  • Durable construction withstands frequent switching and daily use

Compact USB Power Switch

This 30 cm USB cable adds a physical on/off switch to any standard USB-A power source, letting you control USB lamps, fans or other low-power peripherals without unplugging them. It suits desk setups where the host port is hard to reach or where you want a quick tactile toggle. The short length keeps cable clutter to a minimum while still bridging the gap between a hub or charger and the device.

Behaviour under sustained load

The inline switch is a simple mechanical contact rated for typical USB 5 V peripheral currents, so it handles continuous operation of small fans or LED lamps without heating. Because the cable uses standard USB conductors, voltage drop over the 30 cm run stays negligible for devices drawing up to the port’s rated output. No active electronics are present, so there is no thermal throttling or firmware latency to consider during extended use.

Questions about this item

Does the 30 cm cable draw any power or generate heat when the switch is left on all day?

The cable itself has no active electronics; it simply passes power through the switch, so it draws no extra power and produces no noticeable heat.

What type of USB port must my device already have for this cable to work?

It uses a standard USB-A plug on both ends, so the host and the peripheral each need a USB-A port.
