AA Battery Eliminator USB Cable

The Ruth's sister AA Battery Eliminator USB Cable replaces three AA batteries with a USB power source. It supplies 4.5V to devices such as LED lights, radios, toys, clocks, calculators, keyboards and remote controls. The cable draws power from USB chargers, power banks or car adapters. An integrated on/off switch lets you cut power without unplugging the cable.

Practical Limits of USB Power Delivery

The cable provides a fixed 4.5V output and cannot supply higher voltages or currents beyond what the USB source allows. It is unsuitable for devices that require more than three AA cells in series or that draw more current than a standard USB port can deliver. The 3.3ft length restricts placement to within reach of the USB power adapter. Polarity is fixed by the battery-slot contacts and cannot be reversed.

Three AA Battery Replacement Compatibility

This eliminator only works in devices that accept exactly three AA batteries arranged to provide 4.5V. It will not fit products using two, four or any other cell count, nor those requiring a different voltage. The dummy cells must physically match the battery compartment dimensions. Buyers whose equipment uses a different battery configuration or voltage need a different solution.

Questions about this item

Should I pick a longer or shorter cable for my LED lights?

The cable is 3.3 ft long; choose this length if the USB power source sits within that distance from the battery compartment.

What does the 4.5 V rating mean when I plug this into a USB port?

The cable steps standard 5 V USB power down to 4.5 V so it safely replaces three AA cells in radios, toys, clocks or remotes.

Which USB standard does the connector use and what current can it deliver?

It plugs into any USB-A charger, power bank or car adapter and supplies whatever current the host port provides, up to the device's own draw.
