Mastervolt ChargeMaster Plus 12/75-3 Czone

Model: 44310755
  • MasterBus, CZone and NMEA communication.
  • Multicharger with two outputs, one in/output, DC-DC converter, current limiter and VSR.
  • Combine Lithium Ion, Gel or AGM, and large or small battery banks on a single battery charger.
  • Charges multiple batteries while being underway.
  • Offers 20 % more output at 14.4 V and 80 % charging power at 60 °C.
  • Safe Charge: quickly recognize the State of Charge for extended battery life.
  • Very wide operating range of 80-275 V AC, 35-70 Hz.
  • Compact, easy to connect and quick to install.

ChargeMaster Plus is the next generation of battery chargers that integrates multiple functions into one single device. Replacing auxiliary chargers, battery isolators and VSR, ChargeMaster Plus reduces system complexity and cost. Designed for versatility, it charges a maximum of three batteries in a fast and safe way and works anywhere in the world.

With the Battery’s Best Friend architecture, ChargeMaster Plus is capable of charging a multitude of battery chemistries, sizes and voltages. All batteries are charged with the fast and safe 3-step+ charge method. Other unique features are:

The ChargeMaster Plus handles worldwide AC voltages and frequencies. Resisting large voltage fluctuations and high temperatures, it keeps working in harsh environments. For marine and mobile markets, the ChargeMaster Plus is CE, ABYC, UL, SAE, CEC and RCM/C-Tick compliant.

Nowadays, equipment must be self-explaining. The ChargeMaster Plus displays the charge phase of all three outputs in an understandable way. Robust and ergonomic connections save installation time. An integrated VSR eliminates the need for additional components and ensures that the alternators energy is funnelled through to the batteries.

In modern applications, all components work together, the ChargeMaster Plus supports not only MasterBus but also CZone and NMEA. This enables the charger to communicate with displays, shunts and power systems including communication standards like, FireCan, CANopen and many more. The ChargeMaster Plus can operate as a power supply for delicate communication equipment, or during the construction phase of a boat.

Great Watch with Great Sapphire Crystal
Color: Olive/Gunmetal
Waited 2.5 years before reviewing. I love the gunmetal grey case, olive dial, and the exceptional sapphire crystal. The watch is still running great. During cold weather when wearing long sleeves, I make sure I charge the watch monthly by placing it under a table lamp for many hours because it died once due to no daylight charging. One problem is being able to see the minute markings. (The same watch with blue dial is much easier to read.) I also replaced the military-style band immediately with the excellent Archer 20mm Olive band (ARC-QRN-OLV20) and Archer 20mm Matte Gunmetal buckle ( ARC-BKL-GRYM20). I am only allowed to review once for this Timex model, so adding comments about the "Blue" version (TW2V03600JR). The blue version is the same watch but easier to view. It looks GREAT with the Archer 20mm Navy Blue band (ARC-QRN-NVY20).

I design flaw caused me to return it.
Color: Brown/Blue
Pros: - Perfect case size. - Sapphire crystal. - Solar powered quartz. - Large dial face - Minute and second hands reach to minute track for precise reading. - Great field watch design and proportions. - Effective lume on hands. Cons: - Lume on small triangular hour markers is useless, and fades quickly. - The hour numbers are not luminous. - The dull peach color chosen for the hour markers, numbers and hands in dim lighting is very dull and thus hard to read. - The dark blue color chosen for the dial is a dull hue that doesn’t really look blue, but just reduces the contrast between text and markers. - A black dial and bright white markers and numbers would make the watch much more legible/ readable, and would look much better aesthetically. It is a shame that these choices were made on an otherwise perfect design. - I was really excited that Timex finally seemed to get it when they came out with this series of models, but then they handicapped it with a dial that is only useable in bright light. What a shame. I am returning the watch.

Great Watch!
Color: Black/Silver-Tone
I bought this watch after the resin strap on my old Armitron watch broke. I was disappointed to find that armitron doesn't make my old watch anymore, so I had to find a replacement. I did extensive research and finally settled on this watch. I needed a rugged, waterproof, backlit, time-and-date + day of week watch. I also needed a watch with a durable strap, because the resin strap sport watches only last 2 or 3 years, which is how long I had my old one. I love the mid-size design of this watch. It fits well and looks really cool. I bought a used like-new one because it was cheaper and it arrived in perfect condition, just without the instructions or original packaging. It is easy to set, easy to read, and the backlighting is just the right brightness. Setting it accurately is tricky, but I've developed my own system to only be one second off, if that. The band is slightly itchy, but it should break in. Overall, I love my new watch and I'm happy that I found something that can take a beating and still work!

Quality watch at a reasonable price
Color: Black/Red
Velcro-closure on the tough fabric band is comfortable and very secure. This beautiful sports watch allows for 12 or 24-hour timekeeping, and is easy to set. Wearers can program 2 entirety different times using the "Time1" and "Time 2" settings, very useful for travel.

Good Watch; Bad Strap
Color: Blue/Black
The watch is like many other I've worn, Timex included, and has all the features I want in a standard watch. I like the colors which are very similar to my last Timex which I've had to abandon due to failure of the wrist band after many years of daily use and the dearth of stores which replace straps. The watch itself is reliable and works well, but I do not like the velcro strap. I have very small wrists and searched a lot before deciding on this watch with an adjustable strap unhindered by the placement of buckle and holes. However, the strap is still too big to fit me well and it is tedious to align both sides of the velcro. Also, the velcro will catch my sleeves or other parts of my clothing every now and then and is avoidable only through meticulous placment of the two sides of velcro. I myself can't replace a strap with a better one because I don't know how, but if you can and have large enough wrists, then this may be the watch for you. If the manufacture or anyone else knows where one can purchase a small wrist band where the sellers will remove the one that I now have with a new, better fitting one, I wish there were a way that you could tell me. I do wish the watch were flatter because my sleeves are hard to move back and forth over it and it's also in the way of typing on my computer as well as tucking sheets in between mattress and headboard. (I can't rate the light because I haven't yet looked for the switch, and its water resistance I can't comment upon because I have not and will not subject the watch to water.)
