Whether you’re looking to keep your Milwaukee power tool batteries juiced up from your car’s power outlet or you need a reliable way to kick-start your vehicle when its battery dies, Milwaukee offers robust solutions designed for the demands of the road. Let’s dive into how Milwaukee keeps you powered up, no matter where your journey takes you.

Keeping Your Milwaukee Tools Charged in Your Vehicle

When most folks think of a “Milwaukee car battery charger,” they’re often picturing a device that allows them to charge their M12 and M18 REDLITHIUM batteries directly from their vehicle. And Milwaukee delivers exactly that with its M18/M12 Vehicle Charger. This isn’t your average car battery charger designed to replenish your car’s starter battery; instead, it’s a game-changer for tradespeople and DIY enthusiasts who rely heavily on their Milwaukee tools while away from traditional wall outlets.

What is the Milwaukee M18/M12 Vehicle Charger?

The Milwaukee M18/M12 Vehicle Charger (often recognized by its model number 48-59-1810) is a compact, robust unit designed to plug into your vehicle’s 12V or 24V DC outlet, commonly known as a cigarette lighter socket.
