Lost or broke your Milwaukee charger? This is a direct replacement rapid charger that works with both M12 (12V) AND M18 (18V) lithium-ion batteries from Milwaukee. It's compatible with a huge list of charger models (like 48-59-1812, 48-59-2401, 48-59-1804, etc.) and charges all the common M12 and M18 battery packs (CP, XC, HD, High Output, you name it – check the list in the description to be sure). It has an LED indicator to show charging status and uses smart diagnostics to communicate with the battery for optimal charging and longer battery life. Input is 100-240V AC, so it works worldwide; output is 10.8V-18V at 3.0A, meaning it's a rapid charger that can fill most batteries in under an hour. It has overload protection and a cooling system to prevent overheating. Comes with just the charger (no battery). If you've got a pile of Milwaukee tools and need a reliable, fast charger to keep them running, this is a great, cost-effective option. Works just like the OEM one.
