Use a USB Cable to Power your LEDs.

This is a convenient way to power your LEDs.

  • Choose from 3 Volt or 5 Volt USB adapters.
  • Simply plug into any:
    • USB Power Hub
    • USB Portable Charger
    • USB Power Bank

3 Volt:
  • Runs up to 25 of our 3 Volt LEDs.
  • USB uses 5 Volts, so our 3 Volt USB adapter uses a small voltage regulator to bring the voltage down to 3 Volts.

5 Volt:
  • Runs up to 75 of our 5-12 Volt LEDs, depending on the Amps of the power source you are using.
  • A modern smart phone fast charger, either wall plug, or portable power bank, will be able to run 75 LEDs. Slower chargers will run less, with a rule of thumb of 50 LEDs per 1 Amp of power.

This USB connector has a red wire and a black wire. All of our LEDs have a red wire and either a black or green wire. To connect, twist the red to red, and black to black/green.



"How long will the LEDs run between charges?"

It depends on the capacity of your power supply.  A portable charger that charges your cell phone would power 10 LEDs for 150-400 hours.

Power supply

I ordered this to install a garage door open indicator light in the house. Just being able to use an old phone charger for power is the bomb. Compact installation, and so easy to hook up.

Worked as advertised

I didn’t need the usb connection. I hard wired the 5.5v side to a circuit board and it worked fine. An option for getting the voltage reduction module without the usb connector would be nice.

Worked Perfectly

These lights worked just as advertised. I fed them from a different 3 volt source rather than with the battery pack.

USB Jumper

Order from Evan Designs received. I did not know a USB “jumper “ with on/off switch to power my LEDs was available. Fast response. A beautiful little piece of “USB wiring”.
Can’t wait to get more and see what else they make. Great company.
