Make the most of your batteries with the ChargeMaster, plugging in and charging anywhere in the world. Mastervolt’s ChargeMaster guarantees fast and complete charging of your batteries no matter where you are. The ChargeMaster can charge multiple battery banks simultaneously thanks to its combined functionality. Moreover, all ChargeMasters can be easily connected to a MasterBus network with only one cable and one connection (not available on ChargeMaster 12/10 and ChargeMaster 12/15-2). You also have the option of central, local or remote monitoring, configuration and control of your system. The ChargeMaster is available in various models to guarantee you the ideal battery charger for any situation and demand.

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.

Metal-on-metal fitting gives a firm connection, and prevents corrosion or overheating of contact surfaces.

The ChargeMaster series has three equal charge outputs. Those of the smaller ChargeMaster models are pre-installed with two metres 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.

It’s ok
Style: Kids SPF 50, Size: 3 Fl Oz (Pack of 1)
Doesn’t smell like anything, especially not fruit. Seems to work well- it’s what we use on our faces. I started using this all over on my daughter because their spray version is not good.

Overall this is a very good product
Style: Kids SPF 50, Size: 3 Fl Oz (Pack of 1)
I bought this because every sunblock I own eventually gets in my eyes and burns the living daylights out of them. I prefer to use something that isn't laden with chemicals, is cruelty free and reef safe so this looked like it would fit the bill and indeed, it does. It is a true "no tears" formula which I very much appreciate. As with so many zinc based sunblocks there's still a slight "Kabuki mask" effect but it isn't as bad as some of the other zinc products. I wouldn't go so far as to say it's easy to spread because it doesn't have a lot of "slip", doesn't glide like the non-zinc products. You do have to work with it for awhile to get rid of the decidedly chalky consistency but once you get going it seems to be okay. I think somebody else mentioned using a moisturizer before you put it on which seems like good idea even though this is supposed to be moisturizing. Would I purchase this again? I'm pretty sure I will because the "no tears" aspect of the product is important to me. I'll probably use it with a light carrier oil on my face first, let that oil sink in and then put this on top. I'll keep you posted on how that works out. Thank you, Alba Botanica, for being cruelty free and reef safe!

Thank you for making this
Style: Kids SPF 50, Size: 3 Fl Oz (Pack of 1)
I have the most sensitive reactive skin. I regularly will breakout to products that are supposed to be hypoallergenic and non-clogging. I have used this product multiple times and have not had one issue. I also burn in literally 2 mins and I live in Las Vegas. This protected me and my skin did not react. It absorbed in like regularly lotion not leaving any white cast or sticky feeling. There was no scent which is SO important. I wore it only in the sun not swimming so I cannot comment on how well it works under those conditions. I will by this again without hesitation. If you are in need of a high quality sun protector and have skin like a baby or you are a baby this is the best.

In most of all circumstances, this works
Style: SPF 50, Size: 6 Fl Oz (Pack of 2)
For Summer time and when playing and working in the sun, this is my go to sunscreen! I love how it is more natural than all the other ones out there. I have been sort of a spray on sunscreen connoisseur and this is the one that is my favorite. Also, if I have gotten a burn and put this on it, I believe it helps start the healing process on the burn I got. This is at least what I experienced multiple times last year. The only circumstance that this sunscreen fails miserably is in the Caribbean. I recently went on a cruise to that region and applied this sunscreen and it became evident that this and the other brands of spray on sunscreen do not work in Caribbean sun. The only sunscreen that works is the lotion based stuff that you rub into your skin. I have also consulted with friends on spray on sunscreen in the Caribbean and they all fail as well. So, this is why I say that it works in almost every circumstance.
