A good battery charger can make a cordless tool system a heck of a lot more convenient, especially if you use both Milwaukee M12 and M18 tools. Smaller M12 tools are great for tight spaces and lighter jobs, while M18 tools handle bigger projects that need more power. The problem is that batteries always seem to die right when you’re in the middle of something. A faster charger helps keep projects moving, whether you’re working in the garage, handling automotive repairs, finishing home projects, or rotating through tools on a bigger job.
Right now at Walmart, you can get the Milwaukee M12 and M18 Battery Charger on sale for just $50, which is a whopping 60% discount on a charger from one of the top names in cordless tools. The big advantage is that it works with both Milwaukee M12 and M18 batteries, so it’s a smart upgrade for anyone already invested in either system, or both. Milwaukee says it charges battery packs up to 40% faster than their standard charger, helping reduce downtime when you’re trying to keep working.
60% OffThe dual-platform compatibility is the main reason this charger makes sense. Instead of keeping separate chargers for 12V and 18V batteries, you can charge both Milwaukee systems with one unit. It uses sequential charging, meaning it automatically charges the second inserted battery once the first one is fully charged. RedLink Intelligence also lets the charger communicate with the battery pack to monitor cell voltage, temperature, and charge status, which helps optimize performance and extend battery life.
The charger also indicates when a battery reaches an 80% charge, which is useful if you need enough power to get back to work without waiting for a full charge. This rapid charger may not be necessary if you only own one Milwaukee battery and rarely use it, but for anyone with multiple M12 or M18 tools, it’s a solid charging upgrade at $50.
“Fast charging and very convenient for charging both my M12 and M18 batteries at the same time,” commented one buyer.
Another reviewer kept it short and sweet, saying, “It charges the batter really quickly.”
