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.

MOM-1, PANTS-1...well, I guess we both win
Size: 32, Color: Black
Purchased for my 17 yr old son, about 6'2, 180, medium built. PROS -Black pair is a nice happy medium between faded black and pitch dark. -Roomy around the waist, but not enough for children to sag (no, no, no,) -excellent price for quality of product CONS -might be too comfortable for wearer, resulting in an request for an abnormal amount of additional pairs -consistent compliments for wearer could cause inflated ego or confidence OVERALL I didn't hear any complaints from my son or "can you return this" which is a WIN for me, bc he's usually very picky. it's a whole thing with the length and the thickness, color, all of it. I thought these pants looked really nice, the color was casual enough for friends, and dressy enough for church. I was pleasantly surprised. Not a big fan of belts, but he is not comfortable with sagging (thank goodness), and the fit around the waist provided enough support to stay where they needed to. Pants also did not scrunch up at the bottom, and did not fit like capris. Product title described product to a T (or pants): slim fit stretch comfort casual classic solid- it was all of those in one!

Super long length but quality fabric
Size: 28, Color: Army Green
Fits more like skinny jeans rather than slim fit. It’s a size 28 so my waist fits fine but the length is super long for no reason. I decided to keep it due to the fabric material feeling. I fold the bottom of the pants to make it look for fit. I’m 5’4.

Buying more pairs.
Size: 36, Color: Purple
True to fit and extremely comfy. Even tho the title says mens, it’s designed like a womens when it comes to the pockets. Not deep pockets. If you want a tight fit go a size smaller, if you want a baggy fit go size bigger. Color is how you see it in photos.
