Mac Plus 12/12-50 + CZone

Boost the Service Battery

Too often, service batteries don’t get the charge they need. This is a problem made worse by smart alternators and start/stop systems, which result in slow and insufficient charges. The Mac Plus DC-DC charger solves this problem, providing a quick, safe, and consistent charge to the service battery. And, by knowing when the engine is running and providing charge, users can be sure that the Mac Plus will never drain a starter battery.

Proven Mastervolt Quality

Users get peace of mind knowing that they have the best on board. Using the proven Mastervolt 3-step+ charge algorithm, the Mac Plus delivers a quick and easy charge, even for completely flat batteries.

A robust design holds up in even the harshest conditions, with battery temperature-optimized charging and a high-quality aluminum housing to ensure superior protection against dust and water ingress. The power-efficient design also allows the Mac Plus to operate silently and without a fan.

Total Power Flexibility

With a wide DC input range, the Mac Plus allows for all DC sources and can charge two batteries from a single alternator or charger. It supports a full range of chemistries and battery types, including lithium. It also functions seamlessly with modern alternators such as Euro 5 and 6, ensuring proper charging by providing constant power, even when the alternator is inactive.

Parallel configuration of up to ten units will provide over 100 amperes. Advanced high-frequency technology with modern microprocessors ensures minimal power loss when switching from 12V to 24V and vice versa.

Analog voltage sense ports are also available to compensate for voltage drops and maintain proper charging.

Superior Monitoring & Control

Compatibility with CZone®, NMEA 2000®, and MasterBus delivers truly superior monitoring and control and ensures Mac Plus integrates easily into complete systems. Achieve the best performance possible via various controllers and high-quality MOSFETs. And configure the Mac Plus with ease via MasterAdjust, the CZone configuration tool, or even via the on-board DIP switches.

The Best Flavor-Packed Toy to Stuff and Chew! 🐾
Flavor Name: REAL Bacon, Size: Medium
Hello, it’s Skye! I’m back with another very important product update. If you are a dog who loves a challenge and loves real bacon, you need to tell your humans to get you the Benebone Ring Durable Dog Chew Toy. Why this ring is my absolute favorite: The Ultimate Treat Bowl: My absolute favorite part about this ring is the hollow center. My humans stuff it full of yummy treats, freeze-dried raw bites, or a little dog-safe peanut butter, and it turns into the best puzzle bowl ever! I will happily spend hours licking and working to get every single crumb out. Tastes Like Real Bacon: Even after I clean out all the stuffed treats, the toy itself is infused with real, delicious bacon flavor. It doesn't smell like fake chemicals; it smells like the real deal, which makes my nose very happy. Super Durable for Heavy Chewing: I have sharp puppy teeth and I love to chomp, but this durable nylon ring is tough. The curved design makes it really easy for me to flip up with my paws and hold securely while I chew away. It keeps me completely occupied, exercises my brain, and satisfies my need to chew. Five paws up for the best stuffed treat ring ever! 🐶🥓

Flavor Name: REAL Bacon, Size: Small
This chew toy is great for aggressive chewers—it’s very durable and holds up much longer than most other toys we’ve tried. The ring shape makes it easy for dogs to grip and carry, and my dog was immediately interested in it, likely because of the real bacon flavor. It’s also a nice bonus that it’s made in the USA and doesn’t have a strong smell for humans. That said, it is very hard, so I’d recommend keeping an eye on your dog while they’re using it, especially if they’re an intense chewer. Over time, it does wear down and needs to be replaced once the edges get rough. Overall: a long-lasting, high-quality chew that keeps dogs occupied—just be mindful of the hardness and monitor for wear.

Long lasting chew toy!
Flavor Name: REAL Bacon, Size: Large, Flavor Name: REAL Bacon, Size: Large
All I can say is wow! I have a Basset Hound mix who will be in the puppy stage for another year, and as we all know, that means dealing with teething issues. Seeing the photo of this product when it was new makes it obvious what he’s done to it. He’s still at it, chewing like mad. Made for medium to large dogs, he happily totes it around everywhere, and I’m always picking it up so I don’t trip over it. The inner cup can hold peanut butter as a special treat for your pet, and I give him some when he’s feeling a bit bored. It doesn’t last long, but he’ll keep chewing on it for a while afterward. For me, the value is worth the price if it keeps his teeth off my furniture—pet owners know exactly what I mean.

All 3 Dogs Want The Benebone Ring Now
Flavor Name: REAL Bacon, Size: Large
Rescued an Old English Sheepdog and after about 2 weeks, he started chewing things in the house. We knew he enjoyed chewing sticks in the backyard, but chewing things in the house was a no go. Purchased this Benebone Ring (bacon) hoping it would help to curb some of the issues we were having. I am happy to report that so far, after 3-4 weeks of him having the Benebone Ring, he has not chewed a single thing inside the house. He loves this ring and carries it in and out during the day so that he has it with him. The only problem we ran into was our other 2 dogs ALSO wanted the Benebone Ring. While they are not big chewers, suddenly this toy became the must have item in the house. So of course, we had to get more. Highly recommend this chew toy as it is not only durable, it appears to be highly desirable. Keep in mind however that this toy is heavy. So when your dog decides to drop it on your hardwood floors, you WILL hear it in every room in the house!!
