Copper Material USB Cable Male To Female Switch ON OFF Cable Toggle LED Lamp Power Line 28cm

When connecting through this device, its rather high resistance must be taken into account. The voltage drops by approximately 0.3V. Which is actually very good when connecting LED lights to extend their lifespan.

Cool. Works as it should, power bank, switch garland. Now you don't need to hit the power bank connector, just guess the button like on a lamp)

Corresponds to the description. Performs its functions. The connections are quite tight. Convenient, you don't have to disconnect the consumer's power bank every time.

Very good device, the switch works, it is much more convenient when there is a switch.

The button works for turning off and on, everything is excellent, only the package took a month to arrive.

This is not my first time buying - a convenient extension cord with a switch. Thanks to the seller and Joom!

Very satisfied with the purchase, exactly what I wanted. Will order again. Recommend

It’s normal, a bit large, the switch itself is as heavy as for 380 W.

Everything works perfectly. Thank you to the seller and Joom!
