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.

Don’t buy for restaurant industry
Size: 10.5, Color: Black, Size: 10.5, Color: Black
Good looking shoes, fairly comfortable and good value based on the description shared, so I don’t feel it’s fair to rate them lower than 4 stars. I had high hopes for them based on previous reviews from others saying they wore them in the food and beverage industry that mentioned their quality and durability, however I strongly recommend looking elsewhere if you do. I purchased these to wear working in a full service upscale restaurant and in less than two months have managed to have torn the material on the middle exterior section and the bottoms of the shoes are already completely worn down. Good design, but the durability needs to be improved if they’re to hold up for that industry.

DO NOT BUY (lasted less than 7 months)
Size: 11, Color: Black, Size: 11, Color: Black
I bought these for work as a bartender in August of 2025. By December, the tops were scuffed, frayed, and peeling beyond repair, and by February, the soles were coming off. I’ve never had a pair of shoes with such low quality.

Most comfortable shoes, right out of the box!
Size: 8.5, Color: Cognac Napa Leather
Oh my! So, my ordering of shoes online has been hit or miss - 1/2 size too big or too small; too wide or not wide enough. Enter these Marc Joseph shoes… such a game changer. They fit like a glove, exceptionally comfortable, and easy to slip in and out of. I like them so much that I am shopping for another pair. So far, the size, quality, fit, feel, look, and comfort make this pair my dedicated first pick. Btw, I have been wearing them for six hours and they are still very comfortable! I highly recommend these shoes.
