This unique D size adaptor is perfect for converting 1 x AA size cell into a D size cell for use in toys, games and other instruments requiring D size battery power.
To use, simply slide a AA cell (not included) into the adaptor & it's ready for use. Once the charge in the battery has been depleted remove the AA cell & charge in an appropriate charger.
