DAIWA Crystia Wakasagi External Power Supply Alpha Kit #Red

You can turn your Crystia CR/SR electric reel into an external power source.
Compatible with all Crystia Smelt models (except the MR series).
Since you always get the same power as a new reel, you can achieve stable winding speed and power up.
The external power source makes the reel lighter.
Comes with a USB cable.
