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.

Micro-needling effect!
Color: Cyano Pink Spicule
Love how you can feel the micro-needling effect. I use this is my first application after toning and follow up with my serum and moisturizing routine. I do believe it gives my face a plump feeling, especially after gua sha. Will continue to use in my daily!

Helps my moisturizer absorb better
Color: Cyano Pink Spicule
I’m not quite sure if the product is fully working the way it is supposed to but I do like that when I use this and the apply moisturizer, it absorbs into my skin better and leaves my skin smoother and a lot less greasy. It’s easy to throw in my travel bag because of the size and you really only just need a little for each use so it goes a long way got the cost.

Amazing!
Color: Cyano Pink Spicule
This makes my skin feel so smooth. The appearance of my skin also is starting to look a lot better/younger. I've been using it for a week and a half already seeing changes.

Brightens, doesn't firm
Color: Cyano Pink Spicule
I've been using this for about a month now, every night on my face and neck, hoping to reduce the appearance of wrinkles and tighten some of my skin in that area that seems to be losing elasticity. On my neck, I've honestly noticed no real difference in 4 weeks of continued, consistent daily use. The skin on my face does seem brighter and somewhat less textured than before, but I haven't noticed any change in the issues I was hoping this would resolve, based on the claims and how it was marketed. So... not a bad addition to my skincare, but not the solution I was looking for. Some have expressed concerns about it tingling or stinging... You can feel something when you apply it, it's almost like the feeling of static electricity, but it's very mild. I wouldn't let that stop you from giving it a try if you were concerned about it. It didn't cause my sensitive skin any breakouts or redness (although I was applying it at night before bed, so perhaps any redness was calmed overnight). I'm going to go ahead and finish the bottle, but based on these results, I probably won't repurchase.
