The ChargeMaster Plus family is a complete range of battery chargers that provide both efficient and reliable performance in all conditions. This new generation of battery chargers offers multiple functions in one compact device. The ChargeMaster Plus reduces costs and simplifying the system and eliminating the need for additional battery chargers.

The 'Battery's Best Friend' architecture enables the ChargeMaster Plus to charge any battery chemistry using the fast and safe 3-step+ charging method. Different battery sizes can be combined, as the pre-float functionality eliminates the risk of overcharging smaller batteries. The charging profile of the Lithium Ion battery is included, as well as flexibility for a customised, user-defined profile.

The ChargeMaster Plus charges almost any combination of two or three batteries quickly and safely and can handle all possible mains voltages and frequencies worldwide.

The new ChargeMaster Plus models can achieve full functionality within a complete MasterBus or CZone system, or can also be used as a convenient plug-and-play standalone battery charger

The new ChargeMaster Plus can communicate directly with Mastervolt Lithium Ion batteries, MasterShunt or system display for real-time adjustments and optimal performance.

The battery charger can withstand high temperatures and significant voltage fluctuations. That makes this battery charger very suitable for the most harsh, maritime, or mobile environments. In addition, the ChargeMaster Plus has CE, ABYC, UL, cULus, SAE, CEC/DOE, ISO and ACMA certifications.

DO NOT USE THE PROVIDED SCREWS
Color: Black
The screws they include are so cheap and they start to strip halfway in (even with pilot holes). The holders themselves are fine but now now the screws can go in or get out so it's either destroy the product or live with it. I used a quality screw on the one side and it worked just fine. Poor quality and not very thoughtful. If you buy, get your own screws.

Great for Docking Stations & Chargers — Not Just Laptops
Style: Deluxe
I didn’t buy this for a laptop at all—I specifically purchased it to mount my docking station and charger under my desk, and it works perfectly for that. The size is great, the shelf is sturdy, and it keeps everything neatly tucked away instead of cluttering up my workspace. If you’re looking for an under-desk solution for a docking station, charger, or other accessories (even if you don’t plan to mount a laptop), this is absolutely worth it. It cleaned up my whole setup. Highly recommend!

Didn't use for laptop but....
Style: Deluxe
Fantastic for my desk. I ended up using this to mount a Topping DAC under my desk and I used the side cubby to put my Google Nest Mini and Broadlink RF device. Got all that off my desk and everything tucked away just perfect. I haven't used the headphone mount yet, but I plan to use that to, low and behold, hang headphones! These are easy as heck to install and strong enough to hold up anything that will fit in the space for the most part.
