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.

Great puppy teething toy!
My bernedoodle loved this toy. Long after all her teeth had fallen out, she still plays with it! It was great to be able to freeze it and let her gnaw on something that would help her feel a little better too! We both agree that this was extremely helpful and fun!

Golden Retriever puppy did not care for it but other breeds very well might
These seem to be very well made but our Goiden Retriever puppy was only interested in it for less than one minute. Before you buy i would scan the great reviews to see what breeds these really appeal to. I am sure there are some!!

Smells of smoke
The plastic smells of tobacco smoke, my puppy took one stiff and walked away. I wash them with soap trying to get the smell to go away, no change. My dog still would not even try to teethe on this. I do not recommend.

Wonderful teething toys for small teeth!
We bought these for our new three chihuahua babes and they love them so much! For now, since the babies still get really cold, we just do them as is and are going to hold off on freezing them for a bit but it's still great! They love to chew on either end and the different textures of both the rag and the different ones on the bone itself, keep them really entertained.
