Uncover the full potential of this product

The M18 Carry-On 3600W / 1800W Power Supply (2845-20) is a jobsite-ready, cordless inverter power unit that turns up to four M18 batteries into 120 V AC power for demanding tools and sensitive electronics. With a pure sine wave inverter, it can produce 3600 watts starting and 1800 watts continuous power, allowing you to run 15A tools like table saws, compressors, or pipe threaders. The unit also supports simultaneous charging of your M18 battery packs when not in use. Noise-level is kept low (~66 dB), and the compact, emissions-free design makes it safe for indoor, underground, or confined-space use.

  • High Power Output

    • 3600W surge / 1800W continuous pure sine wave inverter to handle demanding 15A tools reliably.


  • All M18 Battery Compatibility

    • Works with any combination of (4) M18 batteries for flexible runtime and battery usage.


  • Simultaneous Charging

    • When not in output mode, the unit can charge M18 batteries at a standard 3A rate each.


  • Pure Sine Wave Output

    • Safe for sensitive electronics, ensuring stable, clean power.


  • Multiple Output Options

    • Includes 120V AC (duplex), USB-A, and USB-C PD ports for both tools and devices.


  • Quiet & Emission-Free Operation

    • Operates without fumes, ideal for indoor or underground jobsites; noise level approx. 66 dB.


  • Compact & Portable

    • Despite its power, the unit is designed to be jobsite portable, fitting in confined spaces, lifts, carts.


  • Lockable Battery Bays

    • Secure your M18 packs against theft using padlockable battery bays (lock not included).

Frequently Asked Questions

Yes, with its 3600W surge / 1800W continuous capability, the 2845-20 is built to run 15A tools like table saws, compressors, etc.

The unit requires 4 M18 batteries to function. You may mix capacities (e.g. 5Ah + 9Ah) but all packs will share load, so runtime is limited by the lowest capacity pack.

No, when the power supply is actively outputting, battery charging is disabled. Charging of batteries occurs only when not in discharge/output mode.

Yes, because it's battery powered and emission-free, it is safe for indoor, underground, or confined space use (no gas fumes).

Around 66 dB, which is relatively quiet for a power inverter unit.

Yes, it uses a pure sine wave inverter which is safe for sensitive electronics, and it provides USB-C PD / USB-A outputs precisely for such devices.

The bare unit weighs 28 lb (? 12.7 kg). Add four batteries, and the total weight increases accordingly. It is compact for its capacity but still requires planning for handling.

Follow the operator’s manual. Avoid overloading, maintain clear airflow around the unit, avoid wet or energized surfaces, and ensure battery bays are securely locked when in use.
