Milwaukee M12 Four Bay Sequential Charger Review

4.0 out of 5

Navigating the vast landscape of power tool accessories often feels like a quest for the holy grail. Among the myriad of options, the Milwaukee M12 Four Bay Sequential Charger promises to be a reliable companion for anyone heavily invested in Milwaukee's M12 battery system. After spending considerable time with this charger, I’m here to provide an in-depth look at its strengths, weaknesses, and overall performance.

Design and Build Quality

The first thing that struck me about the M12 Four Bay Sequential Charger is its compact design. Weighing just over two pounds, it’s lightweight and doesn't take up much space on my workbench. For those with limited space, the integrated hang holes allow for vertical mounting, which is a thoughtful touch. The unit feels sturdy and well-built, typical of what you’d expect from Milwaukee products.

Functionality and Features

At its core, the charger is designed to handle up to four M12 battery packs, but it charges them sequentially. This means it charges one battery at a time, moving to the next only after the previous one is fully charged. This feature can be both a blessing and a curse, depending on your usage pattern.

For someone like me who often juggles multiple tools during a project, the sequential charging can feel slow, especially when batteries are being drained quickly. However, if you’re someone who doesn’t completely deplete your batteries before recharging, the charger’s ability to keep multiple batteries organized and ready can be quite handy.

The charger is equipped with Milwaukee's REDLINK Intelligence, which optimizes performance and extends battery life by monitoring voltage, temperature, and charge status. This is a nice feature that ensures each battery is charged safely and efficiently.

Performance

In terms of charging speed, the M12 Four Bay Sequential Charger performs as expected for a standard charger. It’s not a quick charger, so don’t expect rapid charging times. For instance, a fully depleted 6.0Ah battery takes several hours to charge completely. This can be problematic if you need multiple batteries ready in a short amount of time.

The sequential charging method, while not ideal for high-demand situations, is convenient for overnight charging. I typically load up my spent batteries at the end of the day, and by the next morning, they’re all fully charged and ready to go. This method works well if you plan ahead and have the luxury of time.

Durability and Reliability

Here’s where my experience took a bit of a downturn. Initially, the charger worked flawlessly and was a great addition to my workshop. However, after a few months of regular use, I started encountering issues. The charger would randomly stop working, the indicator lights would go off, and I had to unplug it and plug it back in to get it to function again. This intermittent reliability is disappointing, especially from a brand like Milwaukee, which is known for its robust and dependable tools.

Value for Money

At around $99, the M12 Four Bay Sequential Charger is not cheap. Given the price point, I expected a more powerful unit capable of charging multiple batteries simultaneously. The fact that it only charges one battery at a time and has shown signs of unreliability makes it hard to justify the cost. For the same price, one could purchase multiple single-bay chargers that, combined, would charge batteries faster and more reliably.

Pros and Cons

Pros:
- Compact Design: Takes up minimal space and can be mounted vertically.
- Integrated REDLINK Intelligence: Ensures optimal battery performance and longevity.
- Convenient for Overnight Charging: Ideal for those who can afford to charge batteries overnight.

Cons:
- Sequential Charging: Only charges one battery at a time, which can be a bottleneck in high-demand situations.
- Durability Issues: Reports of the charger failing after a few months of use.
- Price: Expensive for a unit that doesn’t charge multiple batteries simultaneously.

Final Thoughts

The Milwaukee M12 Four Bay Sequential Charger is a mixed bag. On one hand, its compact design and integrated intelligence features make it a convenient tool for those who need to keep multiple batteries organized and ready. On the other hand, its sequential charging method and reliability issues are significant drawbacks, especially given its price.

Would I recommend this charger? It depends on your needs. If you’re a light user who doesn't deplete batteries quickly and appreciates the convenience of having a neat, organized charging station, this charger could be a good fit. However, if you’re a heavy user who needs multiple batteries charged quickly and reliably, you might be better off investing in multiple single-bay chargers or looking for an alternative solution.

In summary, the M12 Four Bay Sequential Charger has potential but falls short in a few critical areas. Milwaukee can certainly improve upon this design to meet the needs of its loyal customer base better. For now, it’s a tool that serves a specific purpose but may not be the best fit for everyone.
