Milwaukee Power Source

The Milwaukee Power Source, model 49-24-2310, is an intriguing gadget that caught my attention due to its compatibility with the M12 battery system and its promise to charge various portable electronic devices. With a 2.1 amp powered USB port, it seemed like a versatile addition to my toolkit, especially given the growing number of devices we rely on daily. Over the past few months, I've put this tool through its paces, and I've gathered some insights that I hope will help you decide if it's the right fit for your needs.

Design and Build Quality

The Power Source is compact, measuring just 2 inches in length and width and standing 4-3/4 inches tall. This small footprint makes it easy to carry around and fit into tight spaces in my tool bag. The build quality is consistent with Milwaukee's reputation for durable tools. It feels sturdy in hand, and the on-board fuel gauge is a handy feature, allowing me to quickly check the battery status at a glance.

However, there are some concerns regarding the durability of the internal components. While the exterior is rugged, the internals seem to lack robust protection against overcurrent and short circuits. This has been a point of frustration, as I've had instances where the Power Source failed after encountering minor electrical faults. Given its intended use with heated gear and other electronic devices, better internal protection would be a significant improvement.

Performance and Functionality

When it comes to performance, the Power Source does a commendable job—most of the time. The USB port charges my smartphone, tablet, and other USB-powered devices efficiently. The 2.1 amp output ensures that even power-hungry devices charge at a reasonable speed. For instance, my smartphone charges nearly as fast as it does with its original charger, which is a big plus when I'm on the go.

One of the standout features is its compatibility with M12 heated gear. As someone who works in cold environments, having a heated jacket powered by the same batteries I use for my tools is incredibly convenient. The Power Source can deliver up to six hours of heat on a single charge, which is more than enough for most workdays. However, I did run into issues when the plug on my jacket frayed, causing the power source to short out. This suggests that while the Power Source itself is capable, the accessories it's used with need to be equally reliable to avoid damaging it.

Battery Life and Charging

Battery life is a mixed bag with the Power Source. Using an M12 2.5 Ah battery, I can get a decent amount of use out of it before needing a recharge. However, when charging devices that draw a lot of power, like tablets or multiple devices simultaneously, the battery drains quickly. For example, charging my tablet from 0% to 100% nearly depletes the battery, which means I need to carry multiple batteries if I plan to charge several devices throughout the day.

Recharging the M12 batteries is straightforward, but it would have been more convenient if the Power Source itself could charge the batteries. As it stands, you need a separate charger, which adds to the gear you need to carry. This isn't a deal-breaker, but it's something to consider if you're looking for an all-in-one solution.

Usability and Convenience

The Power Source is user-friendly, with simple controls and a clear fuel gauge. The compact size and lightweight design make it easy to carry around, and it's a great addition to my toolkit, especially when I need to charge devices on the go. However, the lack of internal protection means I have to be extra cautious about the devices I connect to it and the conditions in which I use it.

One of the more frustrating aspects is the automatic shut-off feature when charging devices that draw minimal power. This can be a nuisance if you're trying to charge something like a low-power sensor or a small gadget, as the Power Source may turn off thinking there's nothing connected. While this feature is likely designed to conserve battery life, it can be inconvenient for certain applications.

Customer Service and Warranty

My interactions with Milwaukee's customer service have been less than satisfactory. When I encountered issues with the Power Source, the process of getting it serviced or replaced was cumbersome. The one-year limited warranty is standard, but the hassle of dealing with service centers and the lack of responsiveness can be off-putting. This is an area where Milwaukee could improve, ensuring that their support matches the quality of their tools.

Final Thoughts

The Milwaukee Power Source is a versatile and handy tool, especially if you already use the M12 battery system. It excels at charging USB-powered devices and powering M12 heated gear, making it a valuable addition to any toolkit. However, its lack of internal protection and the quick battery drain when charging high-power devices are significant drawbacks. Additionally, the customer service experience leaves much to be desired.

Would I recommend the Milwaukee Power Source? It depends. If you're already invested in the M12 ecosystem and need a portable charger for your devices and heated gear, it can be a useful tool. However, if you need something with robust internal protection and longer battery life, you might want to look for alternatives. For those who prioritize convenience and compatibility with existing Milwaukee tools, the Power Source is worth considering, but be aware of its limitations.
