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.

Best affordable squeaker toy
Color: Crinkle Chicken (Brown), Size: Large, Color: Crinkle Chicken (Brown), Size: Large
my dog is obsessed with this toy, this has became his new comfort toy and after having this for about four months the legs are falling off but it’s very durable. The squeaker also moved from the head of the chicken to the body of the chicken but that’s after it was played with every single day. I love that it has two squeakers and it’s the perfect toy for my dog.

My dogs favorite toy EVER
Color: Crinkle Chicken (Brown), Size: Large
I have a Belgian Malinois who loves any and every toy, but this one is definitely her favorite. She will walk around the house constantly carrying it in her mouth, which is honestly adorable to watch. The squeakers only lasted a couple of months, but I don’t really consider that a downside—I’m kind of grateful they didn’t last forever given how much she plays with it. It still remains one of her most-loved toys even without them. My only word of caution is that if you work from home, this toy makes a lot of crinkling noise. And I mean A LOT. It’s great for keeping the dog entertained, but it can definitely get a little frustrating for humans trying to focus or take calls. Overall, it’s been a big hit in our house and easily one of her favorite toys.

Super cute
Color: Bunny (Mauve), Size: Small
Super cute and fuzzy. Definitely perfect size for a puppy and not too loud. The fur is very soft and the nose is sown on not a hard piece that can be chewed on. Very good quality too.

Normally amazing
Color: Spiky Ball (Blue, Orange), Size: Medium
We have purchased these slightly spiky dog balls several times for our very strong jaw heavy chewer dogs and they’ve been amazing. They don’t break down they don’t get torn apart the squeakers don’t even pop out of them. So we ordered another package because we’ve lost a few outside to the lawnmower… oops and the package that got delivered today had only one ball that squeaks and the other does not. THIS IS A PROBLEM ! Unfortunately my female dog got to the new squeaking ball first and my male got to the non-squeaking ball and he was NOT happy. Basically once they claim a ball it’s theirs and the other dogs don’t go near the ball they claimed. So he’s following my female around and every time she squeaks the ball and I’m just waiting for him to attempt to take it from her causing damage to her. Normally… These are amazingly fun, tough, durable but also squeaking balls (that’s rare in a tough ball) that my dogs absolutely love. This time just got a bad batch I guess. When they squeak the dogs LOVE them. After several months of play the squeaker might break inside of the ball but the ball never comes apart or gets damaged. And we as the owners love that they don’t break down are not able to be ripped or torn even by our very strong jawed and big jaw muscle dogs. They are also great for in the house play because they’re small enough that they fit completely inside our dog‘s mouth but obviously not small enough to get swallowed so when we throw them in the house for fetch the dogs can jump up and catch them fully in their mouth so they don’t cause any damage to the walls when they hit the walls. They’re not super heavy but they’re incredibly durable. Definitely worth the price especially if you have heavy chewers or big jaw muscle dogs.

Best fun indestructible toy
Color: Crinkle Duck (Yellow), Size: Large
Truly indestructible no matter how much our oittie tries. She has owned it for three months works at destroying every day with no success. She carries it everywhere. Best purchase for chewer, more fun than the popular rubber heavy duty toy. Do not hesitate your pup will thank you for this fun distraction.
