DEFA 25A Workshop Charger 12V is portable, durable and user-friendly. It features modern Switch-Mode technology, has excellent efficiency, and uses a temperature compensated charging cycle that protects sensitive electronic systems and battery performance. We’ve designed the charger with a 3-meter cable, a wall bracket, a place to hang the coiled cable and an isolated hook.
Equipment damage and injury may result from improper installation and use. Please read the manual/guides carefully. The charger is maintenance-free.
