Milwaukee 49 24 2310 M12 Power Source Review

Not only does it have a USB port, it also has a 12V port I made a cable to use the 12V port to connect other devices with to supply electricity.

Has a standard 12 volt round socket. I measured the voltage with a digital multimeter. It always seems to be on, nothing turns on. Tested charging speed with Ampere App in the range of 800-1100 mA (Pixel XL 8.1)

Essentially useless, no charging cables included, not even a power adapter to charge the M12 battery, all it can do is tell you Saying that the battery level of the M12, otherwise it's useless without charging any devices.

I use a Milwaukee AC adapter for my Milwaukee Tool heated hoodie. This lets me know when to replace a new M12 battery or charge the one I'm using before I run out of charge. I also like the fact that it has a USB port in case I need it for my phone. Just another great product from Milwaukee Tool.

Just received and hardly used. I used to use a Milwaukee speaker to charge my phone/GPS on a motorcycle as I will be using it for that.

This is the second Milwaukee I have had so my daughter can use it to charge her devices after long days of gym training and bus rides to games and events . I've been using mine in my heated jacket and as a travel commuter charger for over a year and have found that it charges my phone very quickly and that I can charge many mobile devices with a single M12 battery. This is probably only really useful if you have or plan to use Milwaukee M12 tools, but I really like this little USB charger.

Like most of my Milwaukee M18 and M12 cordless tools, this USB charger is well thought out, super efficient and super functional. Its sole purpose is to provide an alternative convenient way to charge your cellphone, iPad, etc. and give all your M12 batteries another valuable opportunity. The beauty of this box is that it's not much bigger than your standard M12 battery and actually reminds me of a protective case (for your M12 battery). As a result, it doesn't take up any more space in your…
