The Milwaukee 48-59-1806 M18 Six Pack Sequential Charger is a multi-bay battery charger built for users who run multiple Milwaukee M18 batteries through the day. This is a battery charger designed for charging and managing M18 lithium-ion batteries in one organized station. Model 48-59-1806 gives M18 users a practical way to keep packs moving without tying up the bench with several separate chargers.

The big advantage here is simple: it charges up to six batteries sequentially, one at a time, in a single unit. If you already own several M18 packs, this setup cuts down on the constant shuffle of unplugging one charger, plugging in another, and finding room for more cords. Milwaukee rates the charger to bring M18 compact batteries up in about 30 minutes and M18 extended capacity batteries up in about 60 minutes, which is useful for crews rotating packs between impact drivers, drills, saws, lights, and other cordless jobsite tools.

Milwaukee kept the design compact instead of stretching this into a bulky charging tray. That matters if your charging station lives on a shelf, in a trailer, or on a crowded workbench. The integrated carrying handle makes it easier to move from the shop to the jobsite, and the polycarbonate construction helps it deal with normal jobsite handling better than a flimsy housing would. This is the kind of charger that makes more sense as your battery count grows.

Jobsite practicality is where this unit earns its keep. The pass-through plug helps conserve outlet space, which is a real benefit when power is limited and every open receptacle matters. Integrated hang holes for vertical mounting also make it easier to set up a dedicated charging area instead of letting chargers and cords spread across the floor or bench. If your goal is a cleaner, more organized battery charging setup, this design is working in the right direction.

In the Milwaukee cordless system, compatibility is straightforward. This charger is built for the M18 battery platform and is compatible with all M18 batteries. That makes it a solid fit for users already invested in Milwaukee's 18V cordless lineup. Instead of mixing chargers across platforms or trying to manage a pile of single-port units, you get one charger station for a broad section of the M18 system.

This charger makes the most sense for contractors, service techs, maintenance crews, and serious DIY users who own several M18 batteries and want a cleaner charging routine. If you only have one or two packs, a single charger may be enough. If you are already cycling through multiple batteries every week, the Milwaukee 48-59-1806 M18 Six Pack Sequential Charger is the kind of accessory that saves small amounts of time over and over, and those small wins add up fast.
