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.

Extremely fine shimmer- the air bulb works well for application- Even and controllable
Color: Late Autumn
This is a great way to apply a very fine sparkle. The shimmer is very very finely ground and it sprays out evenly with this air bulb. It does have a lid so there's no chance on it getting everywhere unless you leave the lid off. It also comes with a little plug in the hole so there's two mechanisms there to keep the glitter in the bottle when not in use it's very easy to use and apply and the spray pattern is very even. I got the golden shimmer which looks great with a tan or if you have warmer undertones in your skin. It doesn't require any sort of setter or glue + doesn't have any fragrance. It's a small bottle so it doesn't take up a lot of room.

Exceeded My Expectations
Size: 1PCS, Color: Holo Silver
Love love LOVEEE. I feel like a fairy! You only need a short spritz to get a perfect amount of glitter. The sparkles are beautiful, rainbowy and long lasting. I sprayed some on me yesterday and it's still going strong. It dries quickly and really gets those sparkles down. Even if you rub the part of you that's been glittered, it sticks! It doesn't even have a chemically smell, it's kind of flowery? Which I totally didn't expect. However I would recommend spraying yourself outside because the glitter gets all over the house. Unfortunately (or fortunately) my floor will forever be glittered.

Really pretty sparkle!
Size: 1PCS, Color: Gold
I actually bought this product (one can) so I could spray this on my small area of frog ornaments and rocks by our pool. *The product does not state it is intended for craft use. I am very okay with that. Being in Arizona with sun and wind, I wasn’t sure how this would work, turns out what little I did do, (I was afraid my bottle would run out), did a nice job! Half the glitter I sprayed survived a serious thunderstorm we had one night a week or two ago! I did end up spraying some glitter on my arm, it’s really pretty, subtle, small size glitter, but definitely noticeable outside. You can make your layers as thin or thick as you like. The glitter comes out of the can like hairspray. Very faint smell that will go away within 5-10 minutes, depending on much you use.  I will definitely be purchasing more of this item in more colors in the future.

Must buy!!
Size: 1PCS, Color: Holo Silver, Size: 1PCS, Color: Holo Silver
After carefully looking at the reviews, I ended up purchasing the silver holographic body glitter spray. I immediately sprayed it on my arm, and it blasted my arm full of glitter! I wiped my arm and already dried down! I can’t wait to spray this in my hair and see how long this can last, but I’m definitely buying more with a different variety of colors. Definitely worth the money. I’m obsessed! I will say that if you don’t want glitter everywhere then spray outside.
