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 your service battery. And, by knowing when the engine is running and providing charge, you can be sure that the Mac Plus will never drain your starter battery.

Get peace of mind, knowing that you’ve got the best on-board. Using the proven Mastervolt 3-step+ charge algorithm, the Mac Plus delivers a quick and easy charge, even to completely flat batteries.

A robust design holds up in even the harshest conditions, with battery temperature optimized charging and high-quality aluminium 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.

With a wide DC input range, the Mac Plus allows 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. And 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. And 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 drop and maintain proper charging.

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.

Style: H-shape, Size: 38 inch
Legs seem decently thick. They could be a little sturdier. The paint has stayed with no chips or flakes. Color has not faded. It sits at the perfect height for a desk. Screws and hardware do the job. No welds to speak of, everything screws together. I’ve used these for a year and a half as a school desk and has held up well. I took a sheet of project board with stain and polyurethane as my top. Works excellent

Very sturdy legs!
Style: Zig Zag, Size: 28 inch, Style: Zig Zag, Size: 28 inch
The legs are very well built and good looking, however, the screws included for installation are only 9/16" long which is not nearly enough for table legs of this size. I installed the legs on a 30" x 83" live edge oak tabletop that is full 2" thick. I purchased 1 1/4" screws for the install making the table very solid.

Heavy duty. Looks nice.

These are great. They are VERY heavy duty. I used them with a butcher block counter to make a desk. Worked perfectly.

Good and attractive with a few finish issues.
Style: Zig Zag, Size: 28 inch
These are attractive and functional and work well. Some of the welds were not as precise as I would have liked, and a few places (not conspicuous) are missing a little of the finish, but overall they do what they're supposed to do. I used them with a butcherblock counter top to create a desk for my office.
