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.

It Works
This works fine. Good size. Good enough cord length. Does what a power strip should do.

Great for multiple adapters
Color: Black, Size: 8 Outlet, Style: Outlets Only
One of the common flaws of single width strips is the inability to accommodate more than 1 adapter unless you want to waste the sockets as the adapter obstructs/covers the adjacent sockets. This one has 2 rows with sockets at 90 degrees. As such, adapters face outward and do not obstruct adjacent sockets. Well made and sturdy, typical of APC quality. Hopefully the surge protection won't be tested but gives you peace of mind to know that all plugged in devices are protected. I have it mounted under my office desk using the mounting holes at the back. Great value for the money.

A household staple
Style: Data/Line Protection - 12 ft
I use this power strip for both my computer and entertainment setup, and it has been very reliable. The seven outlets give me enough room for everything without having to use multiple strips. The cord is long enough to reach the wall easily while keeping things neat. It sits flat on the floor and does not tip over when everything is plugged in. The layout of the outlets makes it easy to plug in larger adapters without blocking others. It has already gotten a lot of use and should give me plenty more for years to come.

Perfect!
Style: Data/Line Protection - 6 ft
I somehow didn't notice it had phone jacks on the end of it before I ordered, but this was the only/cheapest option I could find that had a flat plug, and a 6 foot cord, and was a surge protector, AND had indicator lights for protection at least (this additonally has a light for ungrounded). I feel like, what's the point in having a surge protector if it can't tell you whether it's protecting you or not? I needed the flat plug to fit behind a door that remains open fully and has my outlet behind it as a result. Perfect. I don't and probably will never have a use for the phone jacks. It came with a sticker over them which I will just leave for now. But this fit the bill of all other criteria. I guess the 5th criteria was a "known brand" - I didn't want some cheap "travel surge protector" by an unknown company. Belkin, Tripp Lite, APC...don't risk your expensive electronics. I also got a few of the Amazon Basics ones to put around the house and replace the power taps we were using. But they don't have flat plugs.

Quality Product
Style: Data/Line Protection - 12 ft
*** Seller: I bought the Belkin 7-Outlet Home/Office Surge Protector with 12 feet Cord from Amazon.com LLC. *** Shipping and handling: Amazon.com LLC did a wonderful job in packaging this product. It arrived in excellent condition. *** Usage time: I received this product on February 4, 2015, and from the date of this review, I have been using it for 31 days. I'll update my review periodically. *** Performance review: - Negatives. None. - Neutral. (1) The angled plug is convenient for tight spaces. Some people have complained about its right-oriented design, but that doesn't vex me. I simply place the surge protector somewhere to the right of my workstation. (2) I haven't experienced a surge yet (and I hope I never will), so I can't comment on the device's ability to protect my devices. - Positives. (1) Still working after 31 days of continued use (with all seven outlets occupied [laptop, scanner, printer, and so on]). (2) Based on the device's appearance, it looks both sturdy and professional. A reset switch is located on the side. Indicators on top show whether your devices are either protected (green) or not grounded. *** Summary: I thoroughly enjoy this device and would recommend it to anyone seeking a quality product. If this device were to break down, I wouldn't hesitate to order it again from Amazon.com LLC.
