Milwaukee M18 Inverter Power Supply 175W Compact TOP‑Off Adapter with Rafter Hooks

This compact power supply converts M18 battery energy into stable AC power without adding bulky weight to your kit. Designed as an adapter (battery and charger not included), the 2846-20 uses Milwaukee's TOP‑Off technology to maintain consistent output while enabling faster simultaneous power delivery. Built for portability, it pairs with M18 REDLITHIUM batteries to run laptops, chargers, small lights, and low‑draw power tools where grid power isn’t available.

How much continuous power does the inverter provide and what can it run?

The 2846-20 outputs 175 watts of continuous AC power suitable for low- to moderate-draw devices. It’s ideal for chargers, work lights, small electronics, and some hand tools with modest power requirements, but not for high-wattage appliances.

• 175 W continuous AC output for steady operation
• Good for battery chargers, laptops, phones, and LED job lights
• Not intended for heavy-duty, high-current tools or appliances

How does the adapter attach and perform on a jobsite?

The unit features integrated rafter hooks so you can hang it from beams, carts, or other structures to keep cords off the floor. Its lightweight, compact footprint makes it easy to move between stations and store in tool bags when not in use.

• Built‑in rafter hooks for hands‑free mounting
• Small, portable form factor for easy transport and storage
• Durable housing designed for jobsite conditions

Which batteries and accessories are required to use the inverter?

The 2846-20 is sold as an adapter only; you must supply an M18 battery and a charger separately. For best runtime and performance, pair it with Milwaukee M18 REDLITHIUM batteries that match your expected load and runtime needs.

• Adapter-only product — battery and charger not included
• Works with Milwaukee M18 battery platform (choose capacity for longer run time)
• Use appropriate battery chargers from the Milwaukee system

What safety or operational features should I expect?

The inverter provides stable AC output while managing battery demands to prevent overloads from small devices. Standard precautions apply: observe rated loads, avoid prolonged operation beyond battery limits, and use recommended batteries and cables.

• TOP‑Off power management helps maintain steady output during use
• Protect against overload by matching device draw to the 175 W rating
• Inspect cords and connections before each use for safe operation

Who is this for: The Milwaukee 2846-20 is aimed at tradespeople, technicians, and DIYers who need a lightweight, mobile AC source on sites without power. It suits users who already own Milwaukee M18 batteries and want a reliable inverter adapter for powering chargers, small electronics, and low‑draw tools while keeping their workflow mobile and efficient.
