USB 4.5V AAA battery eliminator

This cable replaces three 1.5V AAA batteries with a single USB-powered dummy cell. It suits LED lamps, clocks, toys and similar low-draw devices that normally run on 4.5V. The integrated ON/OFF switch lets you cut power without unplugging the USB end.

Thermals noise and power draw

The unit draws 5V at up to 2A from any USB charger, power bank or car adapter and delivers a steady 4.5V at 1A. No fan or active cooling is present, so operation is silent and the plastic housing stays cool during normal use.

Bundled dummy cable and switch

The package includes one dummy cable set with the series-wired dummy cells and the built-in switch. No driver, software or additional accessories are supplied; the cable simply plugs into a USB source and the device's battery compartment.

Questions about this item

How do I connect the USB AAA eliminator cord and which step is often missed?

Plug the USB end into any 5 V 2 A charger or power bank, insert the three dummy cells into the device's battery compartment in series, then slide the cord's ON/OFF switch to ON — forgetting the switch leaves the circuit open.

What part of the eliminator cord will need replacement first?

The dummy cells are simple conductors with no chemistry to wear out; the USB plug or the in-line switch are the only mechanical parts that can fail after repeated insertions or toggling.

What limits continuous operation of the 4.5 V eliminator cord?

The cord is rated for 4.5 V 1 A output, so any load drawing more than 1 A will hit the current limit first and cause the USB source to shut down or the voltage to sag.
