ChargeMaster Battery Charger - 12 Amp - 3 Bank - 24V

Power You Can Rely On

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 24/6). 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.

Charging Your Batteries With Every Voltage

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. 

Sturdy Connections 

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

Charging Multiple Battery Banks 

The ChargeMaster series has three equal charge outputs. Those of the smaller ChargeMaster models are pre-installed with two meters 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.

  • 3-Step+ charging technology for fast and complete charging.
  • Safe and complete charging due to standard safety features.

Natural and safe
The soap is very nice and lathers well. I got a box filled with different scents. My favorite is the oatmeal lavender. The other scents are not exactly what I would go for. But they are fine. I would prefer coconut or eucalyptus. I like that the soap contains all natural ingredients and no harsh perfumes.

Good price & variety
I ordered this just before Christmas to give away as gifts and gave one to my bf as well. All the scents were strong and I enjoyed them. My boyfriend and I used the one that I gave him (patchouli scent with the scrub) to test it out. It was very exfoliating. It didn’t bother us, maybe we got a good batch, or just have skin not as gentle as others. It felt similar to a sugar scrub. For the price, you get a good amount and variety of this soap. I might get another box just for myself. If you check the ingredients they are actually very simple & natural, not full of parabens or random chemicals that you can’t even pronounce.

Nice soaps!
After visiting Colorado and trying real goats milk soap we have yet to find anything we liked as much. On a whim I purchased this pack. My husband and I both like them very much. As much as we like to shop local it’s been hard to find what we wanted. We will definitely purchase again. We like the scents, the natural exfoliators and the softness it leaves our skin.

Very good bars of soap collection.
My wife doesn’t like the liquid soap because a lot of them say detergent and she says she’s not a dish or a piece of clothing. So this set looks really appealing with a variety of fragrances and scents. It will last you a while. The size of each soap bar is the average size of soap bar. It lathers very well, while being soft on the skin and ganking dirt and odors like it does it’s basically a steal.

Natural, Gentle, and Smells Great
Style: Most Popular
I picked these up to try something more natural, and I love them. They lather well, feel gentle on the skin, and leave it feeling clean without drying it out. The scents are really nice too. They feel like good quality bars.
