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
  • Battery charger and dimmer function
  • Adjustable output voltage

I received this package and I just gave it to my dog. Doesn’t last five minutes. It’s already tore up.

A real review.
Color: 2PC, Color: 2PC
When I saw the Unbreakable Teddy Extreme Bear 2.0, I thought, Finally! A toy that might survive my 9-month-old Rottweiler puppy, Pepper. She’s an aggressive chewer with a love for stuffies—she adores them, right up until she disembowels them and feasts on their cotton insides like a tiny, unhinged zombie. The toy’s name, "Unbreakabear," sounded promising. Durable? Stuffie-like? For large breeds? Sign me up! Fifteen minutes later, it looked like a crime scene from a horror movie. The Good: Pepper was IN LOVE with this toy... for about 10 minutes. The double pack is nice in theory—you know, so you have a backup when the first one inevitably doesn’t live up to its "unbreakable" promise. The Bad: False Advertising: This toy is marketed as "extremely durable for aggressive chewers." But let me tell you: Pepper’s chewing isn’t aggressive—it’s surgical. She shredded the bear’s ears, ripped off the tail, and then went straight for the brain like she was auditioning for Zombie Dogs Gone Wild. It didn’t even put up a fight. Durability (or Lack Thereof): Calling this toy "extreme" is like calling a paper towel roll a chew toy. One good shake, and the seams basically exploded in surrender. Safety Concerns: Once Pepper exposed the stuffing (and the metaphorical "brains"), it was a race to see if I could stop her from swallowing it. Stuffing everywhere. The floor looked like someone had murdered a carnival bear. The Ugly: Walking into the room after Pepper was done was like stumbling upon the aftermath of a teddy bear massacre. The "Unbreakabear" lay limp on the floor, its ears and tail missing, stuffing spewed around like it was the victim of a bear-sized horror flick. Pepper, triumphant, sat there with bits of fluff clinging to her mouth, looking like a deranged extra from The Walking Dead. Final Thoughts: If your dog is a light chewer who likes to gently cuddle their toys, this might be fine. But if your dog sees toys as a challenge, run. Stick to hard rubber toys, Kongs, or something without a vulnerable, squishy middle. As for the warranty? Sure, I could try to get a replacement, but what’s the point? Pepper will just go full zombie surgeon again. Would I recommend this toy? Only if you’re filming a sequel to Teddy Bear Massacre. For aggressive chewers, this is nothing but fluff and disappointment. Pepper’s Review: 5/5 stars for taste. 0/5 stars for durability.

Toy does not live up to its name
Color: 1PC
This product is not sturdy enough for an aggressive chewer as it is advertised. It took my 7-year-old "Rottie" approximately 15-20 minutes to have this "unbreakable, in destructive aggressive chewer" toy rip open and stuffing everywhere. A complete waste of money and I would not recommend this toy to anyone with an aggressive chewer.

Total Rip Off Zero Star Rating Warranted
Color: 1PC
I purchased this product for my dog because it was advertised as indestructible. The second my dog opened the package and put the bear in his mouth the “indestructible bear” was torn apart just below the bear’s head. It was useless and the stuffing was exposed. We had to take the bear from our dog and throw it away. The product was literally destroyed, rendered useless, and unusable in seconds. We had to take the product from our dog fearing he would infest the stuffing which I’m sure would have been harmful to our dog. I have never seen a dog toy that was so easily torn apart and this has never happened to any of the many toys we have purchased and/or given to our dog for play toys. I would rate this product zero stars if possible. Unfortunately one star is the lowest rating you can give when submitting your review. I’m embarrassed I spent money on what truly is junk. We and anyone else should demand a refund for purchasing this product. Sincerely One Disappointed and Disgusted Amazon Prime Member
