Hey, Matthew. Yes, the M18 18-Volt Lithium-Ion Cordless Power Source is compatible with the new heated jackets that use the 2-prong connector. This power source is designed to work with both M18 and M12 heated jackets, providing up to 18 hours of continuous heat on a single charge with an XC battery pack.

      How to turn charging on
      ByJan 31, 2024

      Answer This Question

      This power source doesn't charge M18 batteries. It uses the battery's power to charge other devices via the USB port or 12V outlet. To use it, simply attach a compatible M18 battery. There's no separate charging function to turn on.

        Hi, With this adapter, does the cell phone charge in a way, fast or super fast charging?

          I use this to charge multiple mobile devices that includes fire tablet, iPad and my iPhone. The charge is not fast or super fast. If you want that then you would need the new technology like PD(Power Delivery) or PPS(Programmable Power Supple) but that uses a USB Type-C connector. For USB Type-A which this product has, typical the max is 5V 2.4A a total of 12W, more than enough in my opinion. While at work I use this to charge my phone while listening to music, I always have power!

            Average speed. Not fast but adequate for android phone. Top off is much better.

              I tried this article and it is not Fast Charging for Android as indicated by the package or as indicated by the Milwaukee Toolman, charging by cable as indicated by the cell phone, I tried with a 5A and 12A battery and everything is the same, super slow

                The size of a battery 5Ah v 12Ah wont push more power through the charger the charger pulls 12 watts of power and it is the same for both batteries but the bigger one has more power to supply a bigger load.

                          Can this device be used to charge the m18 battery or is it only used one way with the m18 battery being used only as a power source?

                              Summarized by generative AI from text of customer reviews

                              Customers say the Milwaukee USB adapter is a convenient and reliable power source for charging devices, especially in remote locations or during power outages. Many appreciate its compatibility with Milwaukee's heated gear and its ability to charge phones effectively. However, some users noted the lack of USB-C compatibility and the slow charging speed as areas for improvement. Overall, it is seen as a valuable addition to toolboxes, though enhancements like an auto shut-off feature and additional USB ports would be welcomed.

                              I bought this mainly to use with the new Milwaukee Hexon heated gear. I wasn’t sure if it would work because of the new style connector but it does work fine. Also nice it doubles as a phone charge.
