Workshop charging solution that speeds tool rotation and reduces downtime, introduced as the Milwaukee Multi-Charger. Faster battery swaps keep jobs moving and reduce stress on busy teams. Is the combined M12 and M18 approach the most practical fit for your toolkit?

⚡ At a Glance
  • Charging Capability: Accepts all M12 and M18 batteries
  • Best for: Tradespeople and DIYers needing quick battery turnaround
  • Not ideal for: Users who require simultaneous multi-battery charging ports

Universal compatibility with both M12 and M18 battery platforms. Sequential charging supports 30-minute and 60-minute charge cycles for fast turnaround.


Reduced downtime - with 30/60 minute charge options

Declared charge options include 30-minute and 60-minute cycles, enabling shorter recharge windows for compatible batteries. The faster cycle is suited to smaller batteries while the longer option accommodates larger capacity packs.

Quicker return-to-service for tools, so fewer interruptions on site and faster job completion.

Wide compatibility - with support for both M12 and M18 batteries

Design accepts all M12 and M18 battery types, meaning a single charging solution handles two common Milwaukee platforms. Compatibility removes the need for separate chargers for each battery family.

Simplifies workshop logistics by keeping a mixed fleet charged from one unit.

Managed battery sequencing - thanks to sequential charging

Sequential charging cycles M18 and M12 batteries one after another rather than simultaneously, organising charge order automatically. Managed sequencing helps when multiple batteries are rotated through a single charger.

Allows orderly charging of several batteries so the next pack is ready when required.
