Mac Plus 24/24-30 + 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.

Good intermediate smart toy
This has become one of my puppy's favorite boy's. He is so smart and flustered through the beginning interactive toys quick. I got him this one next. The design is good. He did get through some ok, but got frustrated early with the harder ones. Started flipping and chewing it. It wasnt easy to chew through but did snap a few hinges. Stubborn dog, but still enjoying it. . It moves easily and does stimulate him to think. Great toy especially for smart dogs. Mine is just too impatient and growls at it.

Great toy
Color: Yellow
My dog loved this! Kept him entertained for some time. Only problem I had was trying to unscrew the ends after he was done so I could clean it (my dog slobers a lot lol). With him playing and trying to chew it made the ends tighten more. But over all great toy!

Fun toy!
Color: Yellow
It was funny to see how my cat figured out how to roll the toy to get treats out. Great idea that makes your pet work a little for a reward.

Cool toy
Color: Yellow
Its pretty cool & drops a piece of kibble about every 5'. It rolls easily on my wood floors & has rubber type ends so it doesn't bang up my wood floors. Only downside is my golden retriever doesn't get how to use it yet. Still working on it.

BoYoYo Interactive Dog Puzzle Toy – Daily Slow Feeder That Actually Keeps My Dog Engaged
Color: Yellow
This is one of the few dog products I’ve repurchased—and I use it every day as both a slow feeder and enrichment toy. I have a high-energy dog, and most puzzle toys get solved in seconds. This one is different because of the rolling, unpredictable movement. Instead of just opening compartments, my dog has to actively work to release the food, which keeps him engaged much longer. What stands out: • Works as a true slow feeder: I use this for full meals (not just treats), and it significantly slows eating compared to a bowl. • Higher engagement than standard puzzles: The movement adds a challenge that flat boards don’t have. • Holds up to regular use: I use this daily for meals, and it’s held up well. My dog hasn’t tried to destroy it, but it’s been more durable than most enrichment toys I’ve used. Things to know: • It can be a bit noisy on hard floors because it rolls. • You need a little open space for it to work properly. • Not indestructible—best used with supervision if your dog is a heavy chewer. Bottom line: If you’re looking for something that actually doubles as a slow feeder and keeps your dog mentally engaged, this is one of the few that’s held up in our daily routine. The fact that I’ve bought it twice says everything.
