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.

Lightweight, Protective and Perfect for Everyday Use
Sun protection factor: 50 Sun Protection Factor (SPF), Size: 8 Fl Oz (Pack of 1)
Hawaiian Tropic Everyday Active SPF 50 sunscreen has quickly become my go-to for daily sun protection. The lotion feels light and non-greasy on the skin, which makes it easy to apply and absorb. There is no sticky residue or heavy feeling at all. I love that it’s broad-spectrum and water-resistant so I feel confident that it’s protecting me during outdoor activities, whether I’m at the beach, hiking or just running errands. Plus, being oxybenzone-free is a huge bonus for anyone mindful of ingredients. The scent is subtle and pleasant while not being overpowering like some sunscreens and the 8 fl oz size is perfect for keeping at home or in my bag. Overall, it’s effective, easy to use and keeps my skin safe and hydrated. Highly recommend for daily sun protection!

Lightweight and Smells Amazing
Sun protection factor: 50 Sun Protection Factor (SPF), Size: 8 Fl Oz (Pack of 1)
I was really impressed with how lightweight this sunscreen feels on the skin. It absorbs quickly and does not leave a greasy or heavy feeling behind. The scent is honestly one of my favorite parts because it smells so good and reminds me of being on vacation. I only used it on my body and not my face, and it worked perfectly for everyday sun protection. Overall it is such an easy, pleasant sunscreen to wear and I would definitely buy it again.

Light, non-greasy sunscreen that actually feels good on the skin
Sun protection factor: 50 Sun Protection Factor (SPF), Size: 8 Fl Oz (Pack of 1)
This sunscreen has become one of my favorites for days outdoors. It goes on smoothly, absorbs quickly, and doesn’t leave that heavy, sticky feeling some sunscreens do. The scent is light and tropical, just enough to smell like summer without being overpowering. It gives great coverage and protection without needing constant reapplication. I like using it for beach days, walks, or even outdoor workouts since it holds up well when sweating. It feels moisturizing on the skin and hasn’t caused any irritation. Tip: apply it a few minutes before heading outside so it has time to absorb and start protecting your skin.
