USB AAA Battery Eliminator Cable

This one-metre USB cable replaces two AAA cells with a switched 3 V output drawn from any 5 V USB source. It suits radios, LED lights, clocks, remotes, keyboards, electronic locks and similar low-power devices that normally take a pair of 1.5 V LR03 batteries. The eliminator removes the need to keep buying disposable cells.

For USB-powered low-drain devices only

Users who want to power AA, C, D or 9 V equipment cannot use this cable because the output is fixed at 3 V and the dummy cells fit only AAA compartments. Devices that require more than a few hundred milliamps or that lack a USB charger, power bank or car adapter nearby should look at a different supply method.

Steady 3 V output under continuous use

The cable delivers a constant 3 V as long as the USB host maintains 5 V, so runtime is limited only by the upstream power source rather than by cell depletion. Voltage does not sag the way alkaline batteries do during extended operation, giving predictable performance for clocks, remotes and holiday lights.

Questions about this item

What USB power source do I need to run the 5 V input on this cable?

Any standard USB charger, power bank or car charger that delivers 5 V will power the cable.

Will the 3 V output replace the two 1.5 V AAA cells my device currently uses?

Yes, the cable supplies 3 V (2 × 1.5 V) through dummy cells that fit the same battery compartment.

How can I confirm the cable is delivering the correct voltage after I plug it in?

Measure the output with a multimeter; it should read 3 V when the switch is on.
