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.

Applications:

  • Leisure and professional marine and mobile applications. An effective solution for high power demand onboard and/or the need for prioritized or current limited charging.

Jacket is extremely large
Size: Medium, Color: Classic Light Wash
Runs big, the arms look and feel like they are from a MALE PATTERN AND STICK OUT LIKE IM A MALE BODYBUILDER. Back is very large , too much fabric… the entire jacket. It looked ridiculous on a woman.

Nice jacket but missing inner pockets
Size: X-Large, Color: Classic Light Wash, Size: X-Large, Color: Classic Light Wash
This denim jacket has a good color and design that's makes this noticeable when you do wear it. The shape is like any other denim that's out there and the size is true to fit. There front pockets with decent depth however there's no inner pocket which is a bummer as that's always a nice feature to have. It's not the softest material but it denim and will be durable.

This jean jacket is super cute comfortable and I get a lot of compliments😍🤩
Size: Large, Color: Medium Blue Vintage, Size: Large, Color: Medium Blue Vintage
I absolutely love this denim jacket—it’s become my new go-to layering piece for everything from casual errands to date nights! As a busy mom who needs clothes that can keep up with my day without sacrificing style, this one checks all the boxes. The medium-wash blue denim has that perfect lived-in feel right out of the box, with just the right amount of structure while still being soft and comfortable against the skin. The fit is fantastic—it’s cropped just enough to flatter without feeling too short, hitting right at the waist so it pairs beautifully with high-waisted jeans, leggings, or even flowy dresses. I love the classic button-front design and the chest pockets that add a touch of authentic detail without being bulky. The sleeves are nicely tailored too, with enough room to roll them up for a more relaxed vibe or wear them down for polish. It’s surprisingly versatile for all seasons: throw it over a basic tank or tee in warmer weather, or layer it over a cozy sweater when the evenings get cooler. What really stands out is the quality. The fabric feels sturdy and well-made, with reinforced stitching that makes me confident it’ll hold up through countless washes and wears. No fraying or fading after a few cycles so far, which is huge for something I reach for multiple times a week. It’s also got a nice subtle stretch that moves with you, making it ideal for long days chasing kids or sitting at a desk. I’ve styled it with everything from sneakers and mom jeans for school drop-off to boots and a cute top for church or a night out, and it always elevates the look without trying too hard. If you’re looking for a timeless denim jacket that feels fresh and modern, this is the one! It’s flattering on real bodies (curves and all), easy to care for, and instantly makes any outfit feel more put-together. I’ve already recommended it to several friends, and I can’t imagine my closet without it now.

Great jacket for the price!
Size: XX-Large, Color: White
The denim jacket has a nice relaxed fit without feeling too baggy and it looks great doing it. There's just enough elastic for the jacket to stretch a little without losing its shape. The color's accurate and it's hard to beat the price so I've no notes!
