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.

The ultimate "cozy" blanket—thick, soft, and incredibly warm
Color: 03- Tie Dye Black, Size: Throw (50" X 60")
his Bedsure blanket is the definition of comfort. One side features a velvety smooth faux fur while the other is a thick, plush Sherpa fleece. It’s significantly heavier than a standard throw, making it perfect for cold nights. The black color is deep and rich, and I’ve been impressed that it doesn't shed at all, even after several washes. It drapes beautifully over a couch or bed and adds an instant touch of luxury to the room. It’s the perfect size (50"x60") for curling up with a book or a movie.

Buy this now!!!
Color: 15- Teal, Size: King (108" X 90")
This is probably one of my favorite purchases from Amazon. I have washed it at least 10 times so far and it still looks the same as when I bought it. It is so soft and snuggly I love it so much. The color is beautiful the furry side is soft and the bottom side has Sherpa on it which is also soft. It's not super heavy and it keeps me warm and it fits my king size bed perfectly. It is such a good value for the money and the quality of it is amazing do yourself a favor and purchase this you will get the best Sleep Quality of your life I swear. I wish I would have had this years ago I don't know what took me so long to find it I have bought several blankets and ended up throwing them away because I did not like the way they felt. This one will be a keeper.

Soft and comfy!
Color: 06- Beige, Size: Throw (50" X 60")
The material is very soft and thick, but not to the point where it makes me feel hot. The only reason why it hasn't received five stars is because I ordered the twin size thinking it would give me good coverage (and I didn't want to order a bigger size), but it's just an inch or two too small for my body. But it's not a big deal. I love the quality too! You will get your money's worth for sure.
