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.

Ridley & Colter 😍
Format: Kindle
Romance, Heartache, mystery & banter all wrapped up in one book. I love me a Catherine Cowles book but having Ridley being a true crime podcaster was epic. I absolutely loved the mystery in the book and the heat between the two main characters. I also love a MMC alpha! You cannot go wrong with any of this authors book but this one was a great stand alone with connections to some of her other book characters.

Solidly Enjoyable Romantic Suspense
Format: Kindle
All the Missing Pieces by Catherine Cowles Catherine Cowles delivers a compelling romantic suspense novel in All the Missing Pieces, the story of Colt and Ridley. Colt is the dedicated sheriff of Shady Cove, a quiet small town shaken by past tragedies, including the attempted kidnapping of his sister, Emerson. Ridley, a true crime podcaster, arrives in town searching for answers about her twin sister Avery’s disappearance on the night before their college graduation. What begins as an enemies-to-lovers dynamic between Colt and Ridley slowly transforms into a poignant story of healing, trust, and love. This book is a perfect blend of heartfelt emotion and gripping suspense. Ridley’s grief and determination to uncover the truth about Avery are deeply tragic, adding layers to her character and her growing connection with Colt. The small-town setting and the suspenseful plot keep the pages turning, and the romance feels both organic and tender. Cowles’ writing is on par with her other works—effortless and engaging. I found myself completely immersed, reading and listening to the book in a single evening. (Mild Spoiler!!!) My only critique is the identity of the killer, which felt too far outside the realm of possibility, slightly diminishing the story’s otherwise strong credibility. Overall, All the Missing Pieces is a thoroughly enjoyable read, balancing emotional depth with suspense and romance. Fans of Catherine Cowles and the romantic suspense genre won’t be disappointed.

Great crime thriller! Fun,crazy, strong main character! Surprising & shocking twists! Perfection.
Format: Kindle
Wow what a great read this was !! I just finished it and truly enjoyed this. It had everything that I wanted in a book. I loved the mystery and the crime thriller in this mixed with some really fun found family, love, and crazy fun banter. My heart broke with the journey and the losses and the heartfelt struggles to move forward after loss. I loved how smart, strong and wonderfully crazy Ridley was. It made the story so fun even with the crime saga journey. Loved all the characters and how well they were described. You could honestly picture everything. This had a surprising twist at the end that made it all come together and really shock you. I actually yelled out "OH NO HELP HER! at one point of the book and walked away for a minute and then had to immediately jump back in. lol I really enjoyed this book! Really needs to become a series of this type of crime solving. Great writing. I have found a new great author to follow because I now have to have more of her writing.

If you have read one, you have read them all
Format: Kindle
Catherine Cowles isn't a bad author, but she's incredibly predictable and NEVER deviates from her formula. It's getting to the point it's grating at this point. I feel like I should have a checklist. - heroine is feisty but vulnerable? Check - hero is grumpy with some cutesy nickname for the heroine that he WAY overuses? Check - there will be some mystery in the plot and heroine will need rescuing because of danger she manages to get herself into multiple times? Check - characters have bizarre names you will rarely encounter in real life and I swear are the results of a love affair with a baby name book? Check, but tbf these aren't too bad, usually her books are worse - plenty of quirky side characters with potential for additional books? Check If you want predictability and safety then by all means, go for it. There's just something about her books I'm rapidly losing interest in. I think it's the cutesy pet names the hero gives the heroine I can't stand anymore. They are NEVER something you'd hear on real life and they are very overused. Why can't she ever make it based on the character's name? Why is it ALWAYS some random word like "chaos" or "trouble" or "rebel" or "reckless"?

My first 5+-starred read of 2025!
Format: Kindle
This! This is Catherine Cowles's best work to date, and I'm saying that as a reader who has perused all her books and have enjoyed the heck out of them. All the Missing Pieces is a complete standalone; yes, there's a mention of a character from a previous Cowles novel, and I wouldn't mind a novella for two supporting characters, but for all intents and purposes, this romantic suspense masterpiece can absolutely be read on its own. If you're new to this author, this book is an amazing place to experience her storytelling; if you've read Cowles before, sit back and relish all of the small-town rom-sus goodness. When Ridley Sawyer Bennett (27) arrives in the small town of Shady Cove, California in Bessie the van with cat Tater riding shotgun, she quickly wears out her welcome when her true intentions come to light. The true crime podcaster is connecting dots, suspecting unsolved abductions, including her own twin sister's from five years ago, and murders are linked to one person--and that it all began with what happened to Emerson Sinclair nearly a decade ago. The residents of Shady Cove, however, are protective of Emmie, most especially the town's sheriff, Colter Brooks (36). He wants nothing more for Ridley to up and leave, but Colt is also at war with his pesky attraction to her. Soon, they're not only teaming up, they're diving into their fiery connection. Are they wading into long lost answers or could they quickly drown in danger? Unsolved crimes, undeniable chemistry, small-town feels, AND fur babies?! Catherine Cowles delivers what has just become my very first five-plus-starred read for 2025. All the Missing Pieces is her first traditionally published novel, and let me just say this: The hype is oh-so-real. Cowles kept me on my toes, leading me to second-guessing whoever I had atop my list of potential suspects. Heck, there was a point in the story where I actually wasn't sure about the entire list I had! So, the suspense aspect was a hit with me, and the romance? Gah! The tension between Ridley and Colt was superb! Think not merely a chef's kiss but several of them. This book grabbed me from the get-go and just never let go. Five-plus stars!
