Charge Mate Pro 90

Current limited electronic charge relay with high efficiency and reverse current protection

A secondary battery onboard requires a dedicated charging solution. The Charge Mate Pro makes it possible to distribute the charger or alternator current effectively between two battery banks such as a starter and a service battery. The Charge Mate Pro connects both batteries during charging and keeps them isolated when discharging. This significantly reduces the risk of a flat starter battery for example.

The Charge Mate Pro offers an additional advantage over mechanical charge relays, by limiting the charge current to the second battery. The primary battery, like a starter battery, is therefore charged with priority. The return current is automatically blocked even when the secondary battery has a higher voltage. An emergency start function is possible by connecting an optional bypass switch to the ChargeMaster Pro.

A marine application example is the connection of a bow thruster battery to a service battery. The Charge Mate Pro ensures that the service battery is always charged with priority. The blocking of the return current from the bow thruster battery guarantees that the bow battery remains charged while the current limiting also prevents power dips of the onboard electrical network.

The Charge Mate Pro series consists of a 40 Amp and a 90 Amp version, both suitable for charger or alternator applications. The Charge Mate Pro 90 ensures a higher charge current for example when charging Lithium-Ion batteries. It is also perfectly suitable for large automotive alternators up to 180 A and can be used in parallel operation with a 225 Amp alternator to fulfill even higher continuous power demands of your equipment on board.

Charge Mate Pro: for controlled charging from a single source.

Not for sensitive skin
Size: 2.5 Fl Oz (Pack of 1)
I have combination skin, prone to acne, and sensitive skin. Even though this is labeled as non-comedogenic and best suited for oily skin, I still experienced acne because the consistency of the sunscreen is really thick. It makes it hard to blend (really hard) and upsets my skin. It also smells a lot like alcohol, more so than most sunscreens, even those from this brand. I bet it's good for some skins but it simply wasn't for me.

Finally!
Size: 2.5 Fl Oz (Pack of 1)
I have been looking for a sunscreen that does not breaks me out or irritate my eyes and this was perfect. I wash my face in the morning and I put this sunscreen on. I don't need to use moisturizer since this is enough. It does leave my skin glowy which I like but not greasy. I notice even my dark spots are fading but because I do use this everyday. My skin is tan and it does not leave a white cast. I love it. If you have acne prone skin, oily and sensitive give this a try.

Finally! An SPF Hubby will wear!
Size: 2.5 Fl Oz (Pack of 1)
I've bought my husband at least a dozen SPFs--everything from drugstore to premium brands--and he won't wear any of them. He's 64 years old with oily, extremely sensitive skin (rosacea and dermatitis), and a tendency to sweat a lot in the summer heat, as he's very active. As for SPF, he hates the white cast, how heavy it feels on his skin, and how his eyes burn when he sweats and the SPF gets in them. But I keep trying. Since Eucerin was the only SPF I was able to tolerate after radiation, I tried this one for him. It's the only one he's liked. There's some white cast initially but it settles quickly. He says the lotion doesn't feel heavy, hasn't caused any irritation or breakouts, and doesn't bother his eyes either. He actually wears this one!!! I'm thrilled! Thank you, Eucerin!

Good sunscreen
This sunscreen works well, and has coconut oil base, which is good for your skin. The cans have an adequate amount in them, but I would also like to see something twice their size, if that's possible.
