ChargeMaster Plus 12/35-3 Battery Charger

Make the most of your batteries with the ChargeMaster series, plugging in and charging anywhere in the world. Mastervolt’s ChargeMaster guarantees fast and complete charging of your batteries no matter where you are. Thanks to Mastervolt’s innovative 3-step+ charging process, batteries also perform better and last longer.

All ChargeMasters can be easily connected to a MasterBus network with only one cable and one connection (with the exception of the ChargeMaster 12/10, ChargeMaster 12/15-2, and ChargeMaster 24/6). What’s more, you have the option for central, local, or remote monitoring, configuration, and control of your system.

Clear Display

A clearly lit display on the ChargeMaster provides all essential information: charge current, charge voltage, charge phase, and battery content measurement and/or battery condition measurement as a percentage of available Ah capacity. The display also provides an indication of MasterBus communication. Three buttons adjacent to the read-out panel allow for easy operating of the entire system. 

The ChargeMaster is available in various models to guarantee you the ideal battery charger for any situation and demand.

Features:

  • For recreational and semi-professional use.
  • Suitable for any type of battery, including Lithium-Ion batteries.
  • 3-Step+ charging technology for fast and complete charging also charges depleted batteries.
  • Memory function prevents overcharging in case of unreliable mains.
  • Safe and complete charging due to standard safety features.
  • Charging capacity up to 1000 Ah battery banks.
  • Easy to connect and quick to install.
  • Can charge multiple battery banks simultaneously.
  • Built-in system functionality (MasterBus) in combination with other Mastervolt products.

  • Supplies your system without a battery.

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.

Robust Connections 

Solid metal-to-metal connectors equipped with strain relief prevent corrosion and overheating.

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.

Sun Safe and Satisfied
Living in Arizona, where the sun reigns supreme, finding a reliable sunscreen for my daughter has been paramount. Our spring and summer are filled with swimming lessons, poolside gatherings, and outdoor adventures. In this sun-drenched setting, Coppertone SPF 70 Sunscreen for Kids has become our go-to sun protection. The standout feature for me is its thick consistency. It’s a parent’s little helper, allowing clear visibility of where the sunscreen is applied to ensure no spot is missed. And the results speak for themselves – my daughter hasn't had a sunburn since we started using it. While she doesn’t have the fairest skin and tends to tan rather than burn, the effectiveness of this sunscreen has been impressive. I’ve even used it on my own skin, particularly on my shoulders, and I'm happy to report no sunburns there either. It’s reassuring to have a product that I can trust for both myself and my child. However, I’m aware of the growing concerns regarding certain sunscreen ingredients and their potential health implications. Coppertone SPF 70 contains a mix of chemical sunscreens like Avobenzone, Homosalate, and Oxybenzone. These ingredients have raised questions in recent years. Some studies suggest that chemical sunscreens can be absorbed through the skin and into the bloodstream, leading to potential health risks. Oxybenzone has been under scrutiny for its potential effects on coral reefs and marine life, as well as concerns about hormonal disruption in humans. While these ingredients have been effective in preventing sunburns for us, I understand the importance of making informed choices, especially when it comes to health and wellness. As with any health-related product, I encourage others to research and decide what’s best for their family, considering both the effectiveness of sun protection and the potential impacts of ingredients. In conclusion, Coppertone SPF 70 has been a reliable ally in our family's fight against sunburns. It's a product that offers peace of mind when it comes to sun protection, but mindful consideration of its ingredients is advised for those who are concerned about the broader implications of chemical sunscreens.

Amazing how fast it goes on without the white look!
This stuff is amazing!! I wear baby sunscreen because I rub my eyes a lot, but most of it takes forever to rub in and not look white. This rubs in immediately like any other sunscreen, and it doesn’t burn my eyes at all, not even when I scratch my face and then rub my eyes. So it’s great for small children too, not just 75 yr old ones!

Used for years
I have used this sunscreen since my kids were toddlers. I don’t find it sticky and it turns clear pretty fast. I don’t typically need to reapply on them more than once.

Reliable Sunscreen For Active Days Outside
Size: 8 Fl Oz (Pack of 1), Style: SPF 30
I picked up this Banana Boat Sport Ultra SPF 30 for days when I know I will be out in the sun for a while and it has done a good job. The lotion spreads easily without feeling overly thick or greasy, and it soaks in fast enough that I am not left with a heavy white cast. It stays put well when I am sweating or in and out of the water, which makes it a good choice for the beach, pool, or outdoor sports. I like that the scent is light and not overpowering, and it has not irritated my skin. As long as I apply it generously and reapply as directed, I have stayed comfortable in the sun without getting burned. The 8 ounce bottle is a nice size for throwing in a bag and it lasts through several outings. If you want a dependable, water resistant sunscreen for active use, this one is a solid pick.
