Recharge in the field from a standard 12V battery. Plug into any vehicle or boat for in-the-field charging. Great for outpost trips where your knife sees a lot of shore lunch filleting. Requires the charging station that comes with the PGEFR knife set.This is cannot be used with the Rapala Lithium Ion Battery/Knife - the 12V DC Charger is for the Deluxe Cordless Fillet Knife Set (item PGEFR) only.
