Make the most of your batteries with the ChargeMaster, plugging in and charging anywhere in the world. Mastervolt’s ChargeMaster guarantees fast and complete charging of your batteries no matter where you are. The ChargeMaster can charge multiple battery banks simultaneously thanks to its combined functionality. Moreover, all ChargeMasters can be easily connected to a MasterBus network with only one cable and one connection (not available on ChargeMaster 12/10 and ChargeMaster 12/15-2). You also have the option of central, local or remote monitoring, configuration and control of your system. The ChargeMaster is available in various models to guarantee you the ideal battery charger for any situation and demand.

The Mastervolt ChargeMaster supplies a maximum capacity wherever you are via auto-ranging. Auto-ranging ensures perfect fully automatic operation anywhere in the world, regardless of the available mains voltage (90-265 V AC, 50 or 60 Hz). The 3-step+ charging technology guarantees fast and complete charging, while the cos phi 1 regulation gets the most out of limited generator capacity.

Metal-on-metal fitting gives a firm connection, and prevents corrosion or overheating of contact surfaces.

The ChargeMaster series has three equal charge outputs. Those of the smaller ChargeMaster models are pre-installed with two metres of cable for a plug & play solution, while the heavier models have one full output (for example for your service battery) and two outputs of 10 A, ideal for your starter batteries.

10 stars!
Color: black, Color: black
These gift bags are on another level! The card stock is heavy duty and the quality is out of this world. Your guest will love anything inside this bag. The tassel and tiger tag is so unique and makes this extra special. It’s a medium sized bag and can hold a good amount of stuff. I would love to see these in different colors as well. Truly a wonderful gift bag!

Excellent looking large watch for the price.
Color: 2942 All Silver, Color: 2942 All Silver
The face of this watch is large and maybe it needs to be to fit in all the detail. There are multiple layers inside the face at different levels that make it look intricate and complex. The watch that I received was described as being all silver in the color selection. However, in reality, the face is mostly white with silver markings and silver detail. Even with all of the details and markings on the watch face, it’s still relatively easy to read the time because of the contrast between the polished silver color hands and the white face. The bracelet and the watch itself is metal and heavy in feel. The watch is substantial to handle and feels solid. The bezel is curved rather than flat, adding to the interesting appearance of the watch. It has regular time, date, a timer that is activated by the upper and lower buttons on the side. The moon phase is settable with the stem. All functions of the watch are good, but the timer / stopwatch function a little imprecise and fidgety. I still like it because it’s decorative and complex looking. The watch comes in a simple gift box with adequate padding and was wrapped in clear rubbery plastic material to keep it from scratches. There is an included tool that pushes the pins out of the bracelet so that you can change the size yourself. It’s very easy to use if you have a little coordination and patience. The pins are pushed out in the direction of the arrows on the inside of the bracelet. The bracelet feels solid and looks pretty good. The bracelet is wide making the watch look balanced, and helping create a comfortable wear experience with this relatively heavy all metal watch. The cost of these watches is low, which might be good for those who are tough on their watches or lose them. That with a wide selection of styles and colors also makes it possible to have a collection without much investment. I have several of these watches and have not had one break or stop functioning. I’m amazed that they can offer such a decent looking watch at this price.
