Key Features
Smarter Circuit UseThe system monitors power draw and switches outlets on as capacity opens up, so you can run more battery chargers on one 15 amp circuit without tripping breakers. Built for Bulk ChargingThis Milwaukee 3333-15A 15 Amp Circuit Power Manager is made for shops, service vans, and crews charging a lot of M12, M18, and MX FUEL batteries over long stretches, including overnight. 12 Organized OutletsTwelve NEMA 5-15 outlets, status lights, and cable management clips make it easier to keep a charging wall clean and know which chargers are active at a glance.
Overview
The Milwaukee 3333-15A 15 Amp Circuit Power Manager is a power management device built to let you run more battery chargers from a standard 15 amp branch circuit without constantly popping breakers. This is a power manager designed for battery charging management on crowded jobsite, shop, and fleet charging setups. Model Number: 3333-15A. If your crew is running M12, M18, and MX FUEL chargers in the same space, this unit is built to make that setup more efficient.
Instead of treating every outlet like it is always drawing full load, the Power Manager monitors outlet demand and intelligently powers the maximum number of outlets available without overloading the circuit. As batteries finish charging and demand drops, it automatically brings additional outlets online. In real use, that means less babysitting, fewer manual charger swaps, and a better shot at having a full set of packs ready for the next shift.
A big part of the value here is infrastructure savings. For contractors, facility teams, and tool crib managers, adding more dedicated circuits can get expensive fast. Milwaukee built this unit to expand the practical use of an existing 15 amp circuit, helping charge more batteries over time while reducing the need for electrical upgrades. That matters if you are scaling a cordless platform but do not want your charging wall to become an electrical project.
The layout is clearly geared toward real charging stations. You get twelve NEMA 5-15 outlets, each with its own indicator light, plus cable management clips to keep charger cords under control. There is also a power throttle feature that lets you customize total power draw when that circuit needs to share capacity with other equipment. That gives you more control in mixed-use spaces where chargers are not the only load on the line.
Milwaukee also made this unit easier to deploy where crews actually work. The housing is made from polycarbonate, it is wall-mountable, and it is PACKOUT compatible for modular mounting flexibility. Whether you are building a fixed charging area in the shop or setting up an adaptable battery station, that mounting flexibility makes it easier to keep the system organized and accessible instead of leaving chargers spread across benches and floors.
Compatibility is one of the strongest reasons to buy this unit. The Milwaukee 3333-15A 15 Amp Circuit Power Manager is designed for use with battery chargers on 15 amp circuits and is specifically intended to manage larger numbers of M12, M18, and MX FUEL chargers. If your operation runs multiple Milwaukee cordless platforms at once, this gives you one central way to manage charging flow across those systems.
On the practical side, this is an indoor charging solution with a built-in circuit breaker and UL listing, so it is clearly aimed at controlled shop, warehouse, and service environments rather than outdoor exposure. It is not a charger itself, and it is not a generic power strip. It is a circuit management tool for crews who already have chargers and batteries and need a better way to power them at scale.
Who should buy it? This makes the most sense for contractors with a growing cordless inventory, fleet maintenance teams, tool managers, and anyone setting up a centralized battery charging station. If you only charge a couple of packs at a time, it is probably more tool than you need. If you are trying to keep a lot of Milwaukee batteries cycling through one 15 amp charging circuit, this is exactly the kind of product that solves a real problem.

Tool Nut’s Take
Tool Nut’s Take
Milwaukee 3333-15A 15 Amp Circuit Power Manager for crews that outgrew a basic charging setup
This is a smart buy for anyone who has a lot of Milwaukee batteries to keep in rotation and only so much circuit capacity to work with.
- Who it’s for: Contractors, fleet managers, service departments, and shop teams running enough M12, M18, and MX FUEL batteries that charging has become a daily bottleneck.
- Why it stands out: It is not just a strip with more plugs. The intelligent outlet switching, power throttle, and 12-outlet layout make it a real charging management solution.
- Worth knowing: This is an indoor power manager for chargers on a 15 amp circuit, not a charger by itself. If you only charge a few packs now and then, it is more system than you need.
