Milwaukee ROLL-ON 7,200 Watt Integrated Lithium-Ion Battery Portable Power Supply
The Milwaukee ROLL-ON™ 7200W/3600W 2.5kWh Power Supply is a high-output portable power solution built for demanding jobsites.

Powerful Portable Energy
The ROLL-ON is designed to make temporary power easier to manage. Its integrated battery eliminates the need to transport fuel, perform engine maintenance, or deal with pull starts. The instant-start design also reduces setup time, helping crews get equipment running quickly.
The 2.5kWh battery provides the energy storage, while the high-output inverter supplies up to 7,200W of starting power and 3,600W of running power. This combination makes the unit suitable for a range of professional jobsite power requirements.
Multiple Power Connections
The ROLL-ON provides several ways to connect equipment:
2 × 20A GFCI duplex AC outlets with circuit breakers
1 × USB-C port
1 × USB-A port
This configuration is intended to support multiple 20A corded tools, chargers, and personal electronics. The pure sine wave inverter provides clean AC power for sensitive electronics, while pass-through capability allows charging and power delivery to occur simultaneously.
Built for Jobsite Mobility
Moving portable power across unfinished surfaces can be challenging. Milwaukee equips the ROLL-ON with 9.5-inch all-terrain wheels designed to handle surfaces such as gravel, dirt, and mud.
The unit is also compatible with the PACKOUT Modular Storage System, allowing it to integrate into Milwaukee's broader jobsite storage setup.
ONE-KEY™ Connectivity
Integrated ONE-KEY™ technology provides additional control over the power supply. It supports tracking and management features and allows users to adjust the charging rate to help maximize available outlet capacity on the jobsite.
Jobsite-Friendly Design
The ROLL-ON is designed as a fuel-free alternative to conventional portable generators for appropriate applications. Its zero-emission operation, quiet performance, and IP54-rated protection make it suitable for indoor environments and temporary outdoor use while providing protection against typical jobsite conditions.
For additional storage protection, Milwaukee offers a dedicated ROLL-ON 7200W/3600W 2.5kWh Power Supply Cover, model 48-11-3300, sold separately. The cover helps protect the power supply from dust and debris during storage and includes port flaps that allow the ROLL-ON to be charged while covered.
