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.

I love it!
Color: Black, Size: Rechargeable
This thing works great! It holds a charge for a long time. I love that it has different attachments. I use it mainly for mixing powder into my drinks. It is very powerful. The speed is adjustable too. It feels good to hold too. It lights up when you squeeze the trigger and when it starts losing charge, the light bar gets shorter. I highly recommend it.

Perfect all-around frother, stand keeps it nice and neat on the counter within easy reach.
Color: Black, Size: Rechargeable
Rechargeable, lightweight, variable speeds and optional whisks all make this the perfect item for your kitchen. You can quickly froth milk for your coffees, whip a small batch of whip cream, and even make mug cakes with the hook attachment. The price is very compatible with the competitors, but the ease of use makes this a top choice. The variable speeds makes it much better to control than the push button ones. When you let go of the pressure switch it turns off, no need for a dedicated on-off switch. Having the pressure switch on the top makes it extremely easy to use! It fits very comfortably in the hand and with the metal stand, looks quite nice on the counter, ready to use at any time. I highly recommend this InstaWhisk!

Great product from a great company
Color: Black, Size: Rechargeable
This product works very well. There are several other whips to use also. I absolutely love the cream it makes and that is important so I can enjoy my morning coffee. I used this whisk for quite a while then all of a sudden it stopped working. I wrote to the company to explain. A few days later they sent me a beans new whisk. GREAT item and great company to work with.

Great Frother - almost too powerful
Color: Black, Size: Rechargeable
I’ve been using the Tyohur InstaWhisk milk frother for a while now, and overall I really like it—but I wouldn’t quite give it 5 stars, and honestly it’s because it might be a little too powerful for its own good. First, the positives: this frother does an amazing job. The single-button control is super easy to use, and I love that you can adjust the speed just by how much pressure you apply. It feels very intuitive, and you can really dial in the exact texture you want. Whether I’m making a latte or mixing something thicker like a protein drink, it handles everything smoothly. The performance is seriously impressive. On the lower speeds, it creates nice, silky foam, and when you turn it up, it’s incredibly fast—like café-quality foam in seconds. High-speed frothers like this are designed to create rich foam very quickly, and this one definitely delivers on that promise That said, the power is also what knocks it down a star for me. If you’re not careful (especially when using higher speeds), it can splash pretty easily. The product description says it’s designed to prevent mess with stable low-RPM operation, and that’s true if you stay on the lower settings—but once you ramp it up, you really need to keep the whisk fully submerged or start slow, or it can send milk flying out of the container

Great frother and well built
Color: Black, Size: Rechargeable
I don’t usually write reviews, but since I’ve been helped by so many reviews from others, I wanted to share my thoughts on the InstaWhisk Milk Frother. This is a great frother. It really whips cream into a tasty, rich froth. My wife and I have tried cheaper battery-operated frothers in the past, and while they worked fine at first, they didn’t last very long. The InstaWhisk feels well built and works great. Pro tip: The frother may be a little too powerful at normal speed, so you might need to lightly “feather” the power button to keep the liquid from overflowing the cup. Once you get used to it, it works really well.
