Mac Plus 12/24-30 + 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.

Nice looking and perfect for organizing the entry.
I love this little valet! It looks high quality and the compartment sizes are perfect as a drop for wallet, phone, keys and coins. I use mine on the entry hall table.

Very nice valet tray that gives a dresser or nightstand a much nicer look, and keeps EDC organized.
We’ve been using this sandalwood valet tray (with black "leather" inserts) for about five days, and it has quickly become a favorite for keeping the dresser top organized. It sits neatly on our tallboy dresser, staying put without any sliding, which is a big plus. The tray’s size is just right. This tray is not too bulky, but spacious enough to hold keys, watch, phone, etc., basically all the stuff carried in pockets daily. The wood has a smooth, polished feel, and the stain has a beautiful color which gives it a rich, elegant look that elevates the whole setup. What stands out most are the soft, leather-like inserts lining the compartments. They add a touch of luxury and keep items like my watch from getting scratched or sliding around with a slight bump. I also appreciate the thoughtful design of the notches cut out for phone charging cables. Having those notches makes it easy to keep a phone powered up without a mess of cords. This valet tray feels well-crafted and sturdy, though I would not mind it if the compartments were a tad deeper for bulkier items like a wallet. It’s practical and looks far more refined than the plastic trays I’ve used before, and I feel it gives an excellent value for the money, given today's pricing (July 20, 2025). For anyone looking to tidy up their space with something that feels upscale yet functional, this tray is worth a look.

5 ⭐️⭐️⭐️⭐️⭐️ STARS! Great valet tray for keys and wallets
This valet tray is very classy and made a beautiful wood with nice little touches all around in terms of design. I really like this on my side table in our foyer, and we place our keys, wallets and odd knickknacks that we bring in from time to time. This makes it very easy so not forget or replace things if we have a designated area like this valet pad. This gets my "TRIED-and-TRUE" SOLID 5 ⭐️⭐️⭐️⭐️⭐️ STARS Rating! I only give five star ratings to items that I use and exceed my expectations for quality, functionality, ease-of-use, premium appearance/looks, durability, & when possible: Sustainability/Ease on the Environment. I hope my review helped you gain some insight and I appreciate you taking the time to read it. Thank you!
