Customer Reviews for Milwaukee M18 18-Volt Lithium-Ion Cordless Power Source (Tool-Only)

Love this thing. I use it for charging my phone, or to power my portable computer screen while on the jobsite.

I like it..but ya got to turn it off..or it will drain the batteries

Simple, easy power.

Works Excellent

The product drain the battery when is not in use, I got the one for different brand and they are much better and cheaper

It charged my phone and tablet with no problems but you have to turn off or remove from battery when not in use or it will drain the battery .

Very good performance and lightweight....

Great for the Milwaukee heated jacket to use the m18 batteries that last alot longer than the m12 that comes with the jacket. Worth every cent. Also has usb port to charge phones

Works perfectly. Extremely useful for the heated jacket especially when you don't have any other m12 tools. USB is a great bonus function. Welcomed addition to the Milwaukee lineup!

The main reason I purchased this was to use it with my Milwaukee Heated jackets. This product allows me to use my 18V batteries as well so that I can extend the run time. The device is slim, lightweight, and easily attaches to the battery. I recommend.

easy to use, very portable, will charge cell phone 2-4 times on 2.0 battery and 4-8 times on 4.0 battery depending on how big your phone is. i bought 2 of these 1 for me 1 for my ole lady so we can both charge our phones.will charge anything that uses usb. will work with heated jackets and give incredible run time of 18 hours on 4.0 battery

My biggest complaint with the M18 power source is that the USB output is limited to 500mA. Most current model cell phones or tables will draw anywhere from 1-2A (1000-2000mA) when charging, if supported by the charger. So if you want to use this to charge your cell phone or tablet, expect it to take anywhere from 2-4 times as long to charge when compared with using the charge that came with your phone or tablet. If you're aware of this going in, you won't be disappointed. It works well and charge your phone or tablet multiple times - albeit SLOWLY. If you're on a job site without power, don't expect to use this to fully charge your phone during your lunch break - on a 30 minute break you'll be luck to boost your charge by more than 15%.

i bought the m18 power source as an upgrade for the m12 heated jacket and the m18 lasts longer and heats the jacket up better as showed in the photo the jacket heats up to 85.6 deg(goes higher the jacket was not on long). also the m18 power source has a usb port which is a feature i personally like for charging devices on the go

The milwaukee m18 usb power source works excellent for phone charging or anything that uses usb ports for charging. The battery life is long and it offers quick charging. Works great for using your phone as a flash light with long battery life or emergency charging where you have no power. Great product!

I could charge my iphone three times a day and still have a charge left to work

Unique product for USB charging in the field utilizing your Milwaukee 18-volt battery!

For all the other things Milwaukee did that turned out great, this thing has got to be a joke onto their customers. This is unable to charge my Samsung tablet faster than it drains its battery if watching videos. 4 hour charge time on my Samsung phone, longer if listening to pandora. Was seriously hoping it worked better than what I found. When I travel internationally, would've been awesome to take a 6, 8, or a 12 battery to keep everything topped up. But if this this is the performance given, wouldn't be worth carrying the weight

This works great for a quick and easy power source.
