ChargeMaster Plus 24/20-3 Battery Charger

Make the most of your batteries with the ChargeMaster series, plugging in and charging anywhere in the world. Mastervolt’s ChargeMaster guarantees fast and complete charging of your batteries no matter where you are. Thanks to Mastervolt’s innovative 3-step+ charging process, batteries also perform better and last longer.

All ChargeMasters can be easily connected to a MasterBus network with only one cable and one connection (with the exception of the ChargeMaster 12/10, ChargeMaster 12/15-2, and ChargeMaster 24/6). What’s more, you have the option for central, local, or remote monitoring, configuration, and control of your system.

Clear Display

A clearly lit display on the ChargeMaster provides all essential information: charge current, charge voltage, charge phase, and battery content measurement and/or battery condition measurement as a percentage of available Ah capacity. The display also provides an indication of MasterBus communication. Three buttons adjacent to the read-out panel allow for easy operating of the entire system. 

The ChargeMaster is available in various models to guarantee you the ideal battery charger for any situation and demand.

Features:

  • For recreational and semi-professional use.
  • Suitable for any type of battery, including Lithium-Ion batteries.
  • 3-Step+ charging technology for fast and complete charging also charges depleted batteries.
  • Memory function prevents overcharging in case of unreliable mains.
  • Safe and complete charging due to standard safety features.
  • Charging capacity up to 1000 Ah battery banks.
  • Easy to connect and quick to install.
  • Can charge multiple battery banks simultaneously.
  • Built-in system functionality (MasterBus) in combination with other Mastervolt products.
  • Clear control panel (with the exception of the ChargeMaster 12/10, ChargeMaster 12/15-2, and ChargeMaster 24/6).
  • Supplies your system without a battery.

Charging your batteries with every voltage

The Mastervolt ChargeMaster supplies a maximum capacity wherever you are via auto-ranging. Auto-ranging ensures perfect fully automatic operation anywhere in the world, regardless of the available mains voltage (90-265 V AC, 50 or 60 Hz). The 3-step+ charging technology guarantees fast and complete charging, while the cos phi 1-regulation gets the most out of limited generator capacity.

Robust Connections 

Solid metal-to-metal connectors equipped with strain relief prevent corrosion and overheating.

Charging multiple battery banks

The ChargeMaster series has three equal charge outputs. Those of the smaller ChargeMaster models are pre-installed with two meters of cable for a plug & play solution, while the heavier models have one full output (for example for your service battery) and two outputs of 10 A, ideal for your starter batteries.

DC Power Supply

Even if the batteries are not connected, Mastervolt ChargeMaster battery chargers can provide a constant DC output allowing you to turn on lights or keep the fridge cold.

I wish there was an instruction manual
Size: 10-pc, Color: Black/Stainless Steel, Size: 10-pc, Color: Black/Stainless Steel
I chose this set because somehow other options out there involves more than 1 bread knife and less variety of other knives for some reason and I don’t eat bread. Also I know that this brand is a sister brand of Zwilling which my dad is a fan of so I’m pretty sure of the quality and the sharpness. When I say I wish there was a manual was because 1. I’m not a chef. Nor did I take up any culinary class, so I wish there’s at least a pamphlet in the set to identify which knife does what or what people actually use them for before I use everything randomly, which also works, but I’d like to use them correctly since I bought a decent set. And yes I know I can google it. Just saying would be nice if it comes with one. 2. I wish there was a direction for the block for which knife belongs to which hole. I am pretty sure that usually the blocks would have different depths and the knives come with different lengths. So it would be great to have that indication before I mess up the tip. All in all, it is a really nice set. It is sharp as the other reviews mentioned in their videos. Do handle with care and don’t cut yourself when you’re unpacking them. Knife is sharp.

Thinner than I expected
Size: 7-pc, Color: Brown
This set of knives just arrived and of course, brand new knives look so good. Upon closer inspection I noticed that these knives are not as heavy as the ones they are replacing (not Henckels) and the metal blades actually flex a little when torqued. I am not too thrilled with the scissors either. They also seem flimsy and don't seat all that well in their slot in the block. However, the packaging was the best I have seen in a long time. Box within a box and everything protected and wrapped separately. The wood block is heavy and beautiful. These knives were a good price and I have used Henckels before. I am sure they will do the trick and if I had wanted more heavy duty knives I would have forked over more money for a set. Edit: I am returning these knives. The thin, flexing blades just are not going to work for me. And the scissors are just too flimsy. I honestly expected better from this company.

Excelente
Size: 12-pc, Color: Gray
Quedé encantada con este vestido que compré en SHEIN. La calidad superó mis expectativas. La tela se siente muy buena, suave al tacto y con una caída hermosa que hace que el vestido se vea elegante cuando uno se lo pone. Las costuras están bien hechas y los detalles se ven muy cuidados, no parece para nada un vestido barato. Algo que me gustó mucho fue que el diseño es exactamente igual a las fotos. A veces uno compra en línea con miedo de que no llegue como se ve, pero en este caso llegó tal cual. El color es precioso, el tamaño corresponde bien a la talla y se ajusta muy bonito al cuerpo. También me sorprendió lo cómodo que es. Se puede usar tanto para una salida especial como para un evento más elegante dependiendo de cómo lo combines. La tela no es transparente y tiene buen grosor, lo que da más seguridad al usarlo. Definitivamente volvería a comprar vestidos así. Si alguien está pensando en pedirlo, de verdad lo recomiendo porque la relación calidad-precio es muy buena. Estoy muy satisfecha con mi compra.

I like these. Good solid construction.
Size: 10-pc, Color: Black/Stainless Steel, Size: 10-pc, Color: Black/Stainless Steel
It was past time for new knives. My old set Revereware was way over a dozen years old. One of the handles had broken years ago. One of the best parts of these is the full length of the blade running from tip to end of the handles ( full tang ). The blades of my old ones of went about a half inch into the handles. The blades are about the same thickness. Overall these Henckel's knives are much nicer. I especially like getting the carving knife. I have used that a lot over the years. Both of the scissors are China made. All the Henckels knives say made in India. The Revere knives all say China. I washed them all up. They all shine really nice and the handles are comfortable. I'm happy with them.

Return policy stinks/decent starter set
Size: 12-pc, Color: Cherry
This is a decent set of what I would consider to be starter knives. We purchased a set for our vacation rental home and a second for our son when he was moving into his own place. They are basic knives that you could get away with if you aren’t doing a ton of cooking but you would probably want to fill in with a few other utility knives, as I did even for the rental, if you cook daily. They seemed sharp on the first few uses but they don’t hold the edge so maybe the steel isn’t the best quality. The real reason for three stars is due to the return policy from this seller. We accidentally ordered two sets for our son and the return shipping cost is a good percentage of the purchase price; it’s not like most Amazon sellers who have free returns. We ended up keeping them rather than lose money because we figure we will need to replace them soon.
