Magic 12/12-20 DC Converter

For The Toughest Tasks

The Mac and Magic DC-DC converters are designed for the toughest conditions for professional, semi-professional and recreational purposes. Even under the most extreme conditions, these DC-DC converters operate faultlessly, giving you round-the-clock output when necessary. The sustainability and technologies that underpin the Mastervolt concept have long been proven in practice. With an MTBF of 280,000 hours at full capacity and 24/7 use, the DC-DC converters are ideal for the toughest tasks and any situation that requires a reliable power supply. 

Making The Best Even Better

The reliability and long lifespan of Mastervolt’s DC-DC converters have been established beyond doubt over the past 20 years. While the Mastervolt products have evolved with the latest technological developments, the dimensions and connections have remained the same. As a result it is exceptionally easy to replace one unit with another with only negligible downtime. 

Mastervolt Green by Heart

As part of our constant search for eco-friendly and long-lasting solutions, Mastervolt has developed the Green by Heart program. Its impact on the Mac & Magic DC-DC converters include:

  • An exceptionally effective use of the consumed input current (cos phi) > 0.98!
  • Faster charging of batteries, even with when the input current is limited
  • Use of top quality components with a long lifespan
  • Savings in weight and space
  • Fewer installation materials

MasterBus Compatible

For the DC-DC converters you can use the MasterBus Serial Interface. All you need is a single cable with one connection. Your benefits: Fast and easy installation, plus centralized monitoring, configuration and operation of your system with a MasterView panel.

Programmable via Desktop or Laptop/PC

Remote control the Mac or Magic via your laptop or PC or configure your personal preferences. The device has a communication port and easy installation with a PC-Link and MasterAdjust software.

Energy-Saving Dimmer Function

Many standard light dimmers convert part of the energy to heat and also lose unnecessary energy. The Mastervolt Magic converters regulate the power supply efficiently and without excessive heat build-up, up to 580 watts for optimal safety (multiple Magic converters can be used for multiple lamps).

Parallel Operation

If you have many/heavy power-consuming devices onboard, the parallel use of several units allows capacities of 40, 60 or more Amps. Advanced high-frequency technology with modern microprocessors ensures minimum power loss when switching from 24 to 12 V and vice versa. 

Powerful Selling Points:

  • Reliable and very stable DC supply
  • For 12 and 24 V battery systems
  • Parallel switching of multiple units for capacities of 40, 60 or more Amps

The best
Style: 3.38 Fl Oz (Non SPF)
I’ve been using the La Roche-Posay Toleriane Double Repair Face Moisturizer for a few weeks now, and it’s honestly one of the best daily moisturizers I’ve tried—especially for sensitive skin. First thing I noticed is how lightweight it feels. It absorbs quickly and doesn’t leave that greasy or heavy film that a lot of “hydrating” lotions do. My skin feels instantly softer, but not suffocated. It layers really well under makeup too—no pilling or weird texture. What really stands out is how balanced my skin has been since using it. I tend to get dry patches but also occasional breakouts, and this somehow helps with both. It hydrates without clogging pores, and I’ve noticed less redness overall. The fact that it contains ceramides and niacinamide is a huge plus if you’re trying to repair your skin barrier. It’s also fragrance-free, which I personally look for because anything scented tends to irritate my skin. The only small downside is the price point compared to drugstore moisturizers, but honestly, a little goes a long way and the quality makes it worth it. Overall, I’d definitely recommend this if you have sensitive, combination, or dry skin and want something simple but effective. It’s become a staple in my routine.

Great daily lotion
Style: 3.38 Fl Oz (Non SPF)
Great daily lotion. I love that it is light and fragrance free. It is perfect for day use. I have dry skin and sometimes it is not enough to use by itself. I mostly use it during the day as a base for sunscreen but it feels really good on the face and does not leave my face feeling greasy. The ingredients are really good and the value for money is great. I love LRP products and this is so easy to use.

Moisturizing & repairs skin barrier, but does pill.
Style: 3.38 Fl Oz (Non SPF)
Given myself a couple weeks of consistent use before giving a review. There are a lot of pros to this product which include: moisturizing and stays moisturized all day, made my PIE marks (post acne marks) fade a lot faster. Repairs my skin barrier, especially while using tretinoin nightly, not too thick but thick enough to keep my face hydrated. It does not have a smell. The cons are: slight burn for about 15 seconds but disappears, it pills if I apply too much. It does pill less if I pat it on my face versus rubbing; it does not pill when I apply liquid foundation. I just have to let it dry for 15-20 mins before applying makeup. I found the pros to overpower the cons and will continue to use this product.

Will buy again!
Style: 3.38 Fl Oz (Non SPF)
This is a very nice product. For the size it seems a bit expensive, but a little goes a long way and it may be a better value than I initially thought. My skin does look better, so it is doing it's job! I like the texture of it. It is fairly light, not oily, absorbs quickly into the skin, which I like. Highly recommend.
