Milwaukee® M18 → Speedglas Adflo Adapter (Ultimate Series) v3

Everything from our Premium adapter. Now with task light support and long-term factory serviceability.

The M18 Adflo adapter we always wanted to build.

The Ultimate Series takes everything proven in our Premium M18 adapter and adds a protected task light output, allowing the Speedglas task light to plug directly into the adapter just like it does with the original battery setup.

A dedicated output protection circuit provides charger blocking and protected accessory power while retaining the same true 3-pin Adflo interface, regulated power system and built-in battery protection our Premium Series is known for.

Unlike disposable sealed adapters, the Ultimate is also designed with long-term factory serviceability in mind. Internal components can be repaired, refreshed or repowered where practical, helping keep the adapter in service for years.

✔ Speedglas Task Light Ready

Plug your Speedglas task light directly into the Ultimate adapter. No external battery pack. No separate power supply. No modifications.

✔ Integrated Speedglas Task Light Port

This is the feature M18 users have been asking for. The Ultimate adapter includes a dedicated task light port so the Speedglas task light can plug directly into the adapter in the same way it connects to the original battery system. One battery. One setup. Adflo and task light ready to work.

✔ Dedicated Output Protection Circuit

The accessory output isn't simply wired straight into the battery. A dedicated protection circuit controls the output and provides charger blocking. Properly engineered accessory power instead of just adding another pair of wires.

✔ Built to Be Factory Serviced

The Ultimate is designed as serviceable equipment, not sealed throwaway electronics. Internal components are designed to be replaceable, allowing suitable units to be factory repaired, refreshed or fully repowered where practical.

✔ True 3-Pin Interface System

Your Adflo expects more than just power. The Ultimate retains our proven true 3-pin interface for correct and reliable startup behaviour. No glitches. No hesitation. No guesswork.

✔ Spring-Loaded Battery Connection

Maintains constant contact under movement and vibration. No dropouts. No flickering. No cutting out mid-job.

✔ High-Efficiency Power Regulation

Converts M18 battery power into clean, stable power for the Adflo system. Stable output. Proven performance. Built for long shifts.

✔ Built-In Low Voltage Cutoff

The adapter automatically shuts down before your M18 battery voltage drops too low. No monitoring. No guesswork. Battery protection is built in.

✔ Conformal Coated Mainboard

Added protection against dust, moisture and harsh workshop conditions. Built for real worksites.

✔ Tough ABS Housing

Designed and built in-house by PlasticBurners. Strong, compact, serviceable and worksite ready.

✔ Factory Repairable

If something eventually wears out or fails, the adapter is designed so individual internal components can be serviced instead of automatically replacing the entire unit.

✔ Adflo Plug & Go

No modifications. No complicated setup. Clip in your M18 battery, connect your Adflo and get to work.

Designed for Milwaukee M18 slide batteries and Speedglas Adflo PAPR systems.

The dedicated accessory port is designed for use with compatible Speedglas task lights.

The task light port is an output only. The built-in protection circuit blocks charging through the accessory port.

Battery condition, capacity, age, temperature, filter restriction and task light use can affect operating time. Battery, charger, Adflo unit and task light are not included.

6 Month Warranty

All PlasticBurners Adflo adapters are covered by a 6 month warranty against manufacturing defects and component failure under normal use.

Any returned unit will be inspected and tested to confirm the cause of failure before warranty replacement or repair is approved.

Post-warranty repairs are also available. If your adapter develops a fault after the warranty period, contact us before replacing it. Wherever practical, we can inspect, repair and return the unit at a reasonable cost.

PlasticBurners adapters are engineered for long-term serviceability. Internal components are designed to be replaceable, allowing suitable units to be factory repaired, refreshed or fully repowered rather than discarded.

Where practical, a worn or failed adapter can be returned to PlasticBurners and rebuilt with replacement electronics, connectors and internal components to restore it to reliable working condition.

These adapters are built as serviceable equipment, not throwaway electronics.

Premium was already good. Ultimate finishes the job.
