Milwaukee 48–59–1200P M18 High Output Cordless Power Supply


I recently had the opportunity to test the Milwaukee 48–59–1200P M18 High Output Starter Kit, and I must say, it exceeded my expectations in terms of performance and battery life. The high output HD12.0 battery pack was a game-changer, providing 50% more power and running 50% cooler compared to the standard HD battery packs. This allowed me to push my cordless tools harder and longer, without worrying about the battery overheating or losing power.

One of the standout features of this product is its unmatched performance in extreme cold weather conditions. I used the battery in temperatures below 0F/-18C, and it still managed to deliver an impressive increase in power. This extended battery life made a significant difference, especially on long, cold days on the job site.

The kit also boasts a best-in-class construction, offering long-lasting performance and excellent protection against job site conditions. Overall, I found the Milwaukee 48–59–1200P M18 High Output Starter Kit to be a highly reliable and efficient option for tradesmen who require powerful and long-lasting batteries for their cordless tools.

However, it’s essential to note that the battery pack might not fit all tools, as I encountered some issues with the shop vacuum and had to carefully manipulate the battery to fit it. Additionally, the charger can be a bit heavy and may take some time to switch between battery packs and the charger.

Despite these minor inconveniences, I would highly recommend the Milwaukee 48–59–1200P M18 High Output Starter Kit to anyone who values superior battery performance and extended battery life on their cordless tools.

Milwaukee Charger for M12 and M18 Tools

A few weeks ago, I was frustrated with my charger for my Milwaukee cordless power tools. I had to run around getting extra chargers or waiting longer for charges, but that’s all changed with the Milwaukee M12/M18 charger.

This little guy has been a lifesaver, accepting batteries of all sizes and charging them with ease. It even monitors the battery status, ensuring a full and safe charge every time. And I was pleasantly surprised by the speed at which it powers up my batteries, eliminating wasted time at the jobsite.

But, honestly, there’s one thing that’s been kind of a buzzkill: the charger’s durability. I’ve had to go through replacement after replacement, which really took a toll. I even made a fuss with customer service about warranty issues, but things haven’t gotten much better.

Overall, with a bit more quality control, this Milwaukee charger could have been the best investment I’ve ever made. So, take it as a warning from a power tool-loving friend, and invest in a more reliable option if you want to be productive and avoid constant charger replacements.

Milwaukee USB Charger & Portable Power Source for REDLITHIUM Batteries

The Milwaukee Redlithium USB Charger & Portable Power Source offers users an easy and convenient solution for charging their devices on the go. Equipped with a 2000 mAh capacity, this compact charger is designed to recharge both Milwaukee’s redlithium USB batteries and compatible device batteries. The USB port provides hassle-free connectivity with a variety of devices, while the portable design allows for easy transportation.

The LED fuel gauge displays the current battery charge, and both the batteries and charger are covered under a 2-year warranty. Though some users have mentioned minor issues with the charger’s performance, overall, it seems to be a reliable and well-designed product for those in need of a portable charging solution.

Milwaukee M18 Top Off 175W Power Supply: High-Capacity Charger

In my experience, the Milwaukee 2846–20 M18 Top Off Power Supply has been a reliable tool for me on various job sites. I found it quite practical to have an attached metal rafter hook that allows for versatility when working with limited space on the job.

One of the most significant highlights of this power supply is its compatibility with both AC and DC power sources, making it ideal for charging multiple devices at once. It has also been quite efficient in providing faster simultaneous power to personal devices and small electronics. The combination of its AC 120V outlet, USB-C PD (45W) port, and USB-A (2.4A) port proved to be quite useful, especially in charging devices that require more power.

However, after using the power supply for a while, I noticed that it struggled to provide the full 175 watts of continuous power promised. The power output varied depending on the devices being charged at the same time, and I often found myself waiting for the power supply to catch up.

Additionally, although the product is built with durable materials, I have come across instances where the power supply stopped working altogether. It would simply refuse to turn on, despite being connected to a fully charged M18 battery. This issue has been quite frustrating and has led to a few negative reviews from users.

In conclusion, the Milwaukee 2846–20 M18 Top Off Power Supply is a well-designed, versatile tool that offers multiple charging options for various devices. When it works, it performs well and provides a convenient solution for users who need charging on the go. However, its inconsistent power output and possibility of sudden stoppages could be areas for improvement.

Milwaukee M18 Six Sequential Charger: Compact and High-Performance Battery Charger

The Milwaukee M18 Six Pack Sequential Charger has become my reliable companion in my daily construction work. Its compact size and vertical mounting make it easy to place and access onsite. I appreciate how it charges M18 compact batteries in a mere 30 minutes and M18 XC batteries in 60 minutes.

This charger has significantly reduced the time spent on changing batteries, allowing me to focus on my work and increase productivity at the job site. Although the charger is not as fast when charging larger batteries, its convenience and time-saving benefits outweigh this minor drawback. Overall, I would highly recommend this charger to anyone in need of a reliable and compact charging solution for their M18 batteries.

Milwaukee M18 Portable Power Station

I recently got my hands on Milwaukee’s 2845–20, a versatile 3600W/1800W power supply that’s been a game-changer for me on the job site. The power supply boasts an impressive 3600 starting watts and 1800 running watts of pure sine wave inverter energy, providing enough oomph to power demanding tools like table saws, pancake compressors, or even pipe threaders.

As a contractor, I’m always on the lookout for equipment that makes life a little easier. This power supply fits my criteria perfectly, with its quiet, compact, and emissions-free design that allows me to work indoors and underground, including scissor lifts and utility carts. It’s lightweight and compact, too, making it easy to carry around without adding bulk.

One of the standout features is the ability to charge M18 batteries simultaneously at a 3A standard rate while the product is not in discharge mode. This is great for minimizing downtime and ensuring all my tools are always ready for action. Plus, the lightweight and compact design means I can have power by my side instead of relying on gas alternatives and extension cords.

However, there are a few areas where the power supply falls short. It drains the batteries when ‘on’ and not in use, which can be a problem if you need a backup power source. The standby drain is a bit high, and the batteries die in 40 hours even when not in use. This is especially noticeable when using the power supply as a backup for something like a sump pump.

Another minor issue is that it doesn’t support pass-through charging and has no additional charging capabilities. This limits the versatility of the power supply, making it less useful for tasks that require more than one device to be charged at once.

Despite these drawbacks, I’ve found the 2845–20 to be a valuable addition to my toolbox. It’s quiet, compact, and lightweight, making it easy to transport and use in a variety of settings. Its performance is impressive, providing me with the power I need to keep my tools running smoothly. If you’re looking for a portable, versatile power supply that can handle demanding tasks, the 2845–20 is definitely worth considering. Just be aware that the battery life may be a bit of an issue if you plan to use it as a backup power source.

Buyer’s Guide

When it comes to shopping for Milwaukee power supplies, there are several factors to consider to ensure you make the right choice. This buyer’s guide will help you navigate Milwaukee power supply options by focusing on important features, considerations, and general advice for this product category. We’ll cover battery compatibility, power output, charging time, portability, and warranty details to help make your purchasing experience a success.

Battery Compatibility

One of the most important aspects of choosing a Milwaukee power supply is ensuring it’s compatible with your existing Milwaukee battery packs. Milwaukee offers a vast line of cordless tools that require either M18, M12, or 12V MAX batteries. Make sure to check the power supply’s battery compatibility before making a purchase. This information can typically be found on the product’s product page or in the user manual.

Power Output

Another critical consideration when choosing a Milwaukee power supply is its output. The power output determines how quickly your tools will charge and how long the battery will last. Look for power supplies with higher output ratings to get the most out of your cordless tools. However, higher output can sometimes result in slower charging times or more prolonged usage, so make sure to find the right balance for your needs.

Charging Time

Charging time is an essential factor to take into account when picking a Milwaukee power supply. Look for power supplies with fast charging capabilities to reduce downtime when working on a job site. While fast charging can be desirable, it can sometimes come at the cost of a higher price tag, so consider your budget and priorities when making your decision.


Consider the portability of the Milwaukee power supply you’re considering. If you’re frequently on the go or need to charge your tools in different locations, look for a power supply that is lightweight and compact. Smaller, more portable power supplies tend to be more affordable but may have slower charging times. Consider the balance between portability and charging speed based on your specific needs.
