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.

Great replacement patio table umbrella.
Color: Tan, Size: 10 Foot
After a windstorm destroyed my old umbrella on our patio set, I was looking for a new one that wouldn't break the bank but also held up to the direct sun of the summer months. This umbrella did not disappoint! The material part of the umbrella top seems like it is nice and thick and the stitching is overlapped in the corners which should provide a lot of strength for the windy days. I really like the neutral colors of the fabric, as that will go well with the rest of my outdoor furniture. The medal pole portion is perfectly straight and the pivot point connection seems nice and tight. I would think that this umbrella will stand the test of time. No assembly needed, just pull it out of the box and extend the fabric.

Incorrect height shown in listing image.
Color: Tan, Size: 9 Foot
I purchased these for their tall height to go in the ground, but they are too short and I hit my head on them. The height shown in Amazon's pictures does not match the actual height for the 9- and 10-foot umbrella. The heights are something more like 90-95 inches rather than the 108 and 120 inches indicated. The 9- and 10-foot umbrella description seems to refer to the diameter of the umbrella instead. I have returned them, but Amazon has not yet corrected the listing.

Simple, Comfortable, and Exactly What You Expect
Style: Rack with 3 Pairs (5, 10, and 15 Pound)
These are pretty much exactly what you want from a set of dumbbells — simple, functional, and no nonsense. The neoprene coating gives them a comfortable grip and keeps them from feeling slick in your hands, especially during longer workouts or if your hands get sweaty. The coating also helps keep them from banging up floors or making as much noise compared to bare metal weights, which is nice if you’re working out at home. Weight accuracy seems fine for general fitness use, and they’ve worked great for things like accessory movements, shoulder work, lighter presses, rehab-style exercises, and general muscle toning. The shape also helps keep them from rolling around everywhere when set down. They’re not fancy, and they’re not trying to be — they’re just dependable dumbbells that do what they’re supposed to do at a fair price. If you want straightforward hand weights for home workouts without overthinking it, these are a solid buy.

Reliable, Comfortable Dumbbells I Actually Use Every Day
Style: 12 Pound, Pair, Style: 12 Pound, Pair
I’ve been using the Amazon Basics Neoprene Dumbbell Hand Weights daily, and they’ve honestly been perfect for my routine. Whether I’m doing a quick morning workout or adding resistance to a longer session, these have held up really well. The neoprene coating makes a big difference—it provides a comfortable, non-slip grip, even during longer workouts or when my hands get a little sweaty. They’re also easy to clean and don’t have that strong rubber smell some weights can have. I really appreciate the hex shape too. They stay put when I set them down (no rolling across the floor), which makes switching between exercises quick and frustration-free. The weight feels evenly distributed and well-balanced, so movements feel controlled and smooth. Overall, these are simple, no-frills dumbbells that just work. If you’re looking for reliable hand weights for everyday use—whether you’re a beginner or just need something dependable for home workouts—these are a great choice.

I’m really happy with this dumbbell set. The weights are clearly labeled (3 lb, 5 lb, and 8 lb), which makes it super convenient to switch between exercises. The neoprene coating feels comfortable in hand and provides a good grip, even during longer workouts. The storage stand is a big plus—it keeps everything organized and saves space, which is perfect for a small home gym. The colors are also nice and make it easy to quickly grab the weight you need. Overall, this is a great set for beginners or anyone looking to add light strength training to their routine. Highly recommend!
