The ChargeMaster Plus family is a complete range of battery chargers that provide both efficient and reliable performance in all conditions. This new generation of battery chargers offers multiple functions in one compact device. The ChargeMaster Plus reduces costs and simplifying the system and eliminating the need for additional battery chargers.

The 'Battery's Best Friend' architecture enables the ChargeMaster Plus to charge any battery chemistry using the fast and safe 3-step+ charging method. Different battery sizes can be combined, as the pre-float functionality eliminates the risk of overcharging smaller batteries. The charging profile of the Lithium Ion battery is included, as well as flexibility for a customised, user-defined profile.

The ChargeMaster Plus charges almost any combination of two or three batteries quickly and safely and can handle all possible mains voltages and frequencies worldwide.

Excellent little grinder
For the price, this thing is a great value. I wanted to use it a bit before writing a review, because anything can be amazing initially. I have been using it for several weeks now and let me just say that for the price, you get a great little grinder. This thing isn't meant to grind up bags and bags of coffee, but for grinding a nice little bit for a few days at a time, it's perfect. It's easy to set the grind level / coarseness, and it "stays" where you put it. I have not had any issues and it seems pretty durable. I saw some complaints of it being slow, but maybe they just expected electric speeds with a manual grinder? Not sure, but for me I am able to grind a full reservoir (the container of this item) in less than a minute and a half, at best. I got this because sometimes I am lazy and didn't use the electric grinder the night before and I don't want to wake up the wife grinding my coffee, so this is PERFECT. The only thing is, now I don't use my electric grinder anymore.. The reason for that is I get more consistent ground coffee using this little guy than my electric grinder ever has. So now I am stuck in manual mode, and for cheap! This thing is super light and easy to store away, not bulky and won't get in your way. So if you are hesitant because you saw some bad reviews, just do what I did.. buy it anyway and find out for yourself. I have learned that most negative reviews on Amazon are because people expect things to be more than they are or to somehow function beyond their capabilities... This thing does what it's supposed to do, and it does it well. So buy one now, you won't regret it!

Gets it done.
At this price point it is a excellent grinder for coffee. It does adjust for different grinds but there is no scale to gauge, just clockwise or counter clockwise. Recommended if you are not sure if you want one.
