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.

Perfectly Spooky & Shih Tzu Approved!
Color: Skull With Spiders
Mushu and Cri-Kee are absolutely obsessed with this Fringe Studio burrow toy. It is so hard to find plushies that are the perfect scale for a Shih Tzu, but these spiders are exactly the right size for them to carry around and "hunt." The spiders are super squeaky, which keeps both of them entertained for much longer than their other toys. It is adorable watching them dive into the burrow to find their prizes. This toy is high quality, holds up well to their play, and provides the perfect amount of mental stimulation. If you have small dogs who love a squeaky challenge, I highly recommend this one.

Great size for tiny dogs!
Color: Skull With Spiders, Color: Skull With Spiders
We got this for our grand-dog, a tiny Havanese! It's a great size for her. It was challenging to find things she could carry around with her tiny mouth when she was a puppy and we liked the added bonus of her pulling them out of the skull. Another activity in her day.... It was the perfect seasonal item to add to the toy box. It's her favorite thing to carry around. The squeakers are still going strong. It got a little crusty after she played with them for a while, but they washed great! Still holding up! Would recommend.

My little dog's favorite toy
Color: Skull With Spiders
These spiders are small and not for big dogs. But my little one loves them so much and it is hard to find good durable toys small enough for her. I love these spiders so much I wish I could buy just the spiders. the ones they sell alone are too big for her. If some one from the company could help a sister out on how to buy the spiders without the skull I would be for ever grateful.
