Milwaukee M12 | M18 4-Bay Simultaneous Super Charger (48-59-1818)
This is Milwaukee’s newest high-performance charger designed to power both M12 and M18 platforms at once, with true simultaneous charging and “Super Charger” speeds.
Key features
Charges up to 4 batteries at the same time
Bay layout:
2 dedicated M18 bays
2 hybrid bays (M18 or M12)
Adaptive power distribution (CHARGE ADAPT) to maximize charge speed
Active cooling (COOL-CYCLE) to reduce downtime
PACKOUT compatibility for jobsite storage and transport
Works with all Milwaukee M12 and M18 batteries
Speed & performance
Up to 10× faster charging compared to standard chargers
Four M18 FORGE HD12.0 batteries can reach 100% in about 90 minutes
Designed to deliver the fastest charge rates Milwaukee offers while protecting battery life via REDLINK intelligence
Smart charging tech
REDLINK intelligence monitors voltage, temperature, and charge status to optimize speed and battery lifespan
CHARGE ADAPT dynamically shifts power between bays so you get usable batteries faster
Why this charger is a big deal
Compared to older Milwaukee chargers:
Standard or rapid chargers → sequential or slower charging
Dual-bay Super Charger → only 2 batteries at once
4-bay Super Charger → true multi-platform, simultaneous high-speed charging
In other words, it’s designed for crews running lots of batteries and both M12 + M18 tools on a daily basis.
