Genius GEN5X1, 1-Bank, 5-Amp (5-Amp Per Bank) Fully-Automatic Smart Marine Charger, 12V Onboard Battery Charger, Battery Maintainer and Battery Desulfator with Temperature Compensation

They don't fit Australian plugs without a adapter great unit but the plugs let them down you should not have to rewire for our plugs the company is very shot sighted on this matter

I have this installed in my slide in truck camper. It is maintaining and charging its battery when connected to shore power. SO far I have to say, I like this unit. I had an older NOCO that was great, and still is... but it is rated much lower (2.5 AMP as I recall) and did not do Lithium. I decided to up my game and use this in its place and keep the older unit as a spare. The Gen5X1 is a great unit. Its small size and higher AMP rating along with its smart settings and maintainer capabilities make it a real winner in my books. It works great, it easy to use and is very solid. All NOCO devices have excellent connectors and cables as well as a decent quality feel and function. So far after about 1 year-ish I am impressed. RV, Camper, Marine, you name it... this is a handy little unit with some power and versatility.

Is a solid product and it’s waterproof.

I was skeptical at first because there are so many battery chargers/maintainers out there, but after using NOCO Genius chargers for a while, I’m genuinely impressed. I now own FOUR of them. I started with the NOCO Genius 1 for my Kawasaki SxS. It worked so well that I bought a second Genius 1 for my mom’s vehicle. Since then, I’ve added a Genius 2 for my own vehicle and a Gen5 X1 waterproof onboard charger for our boat. Everything about these chargers feels premium. The packaging is excellent, the cables are thick and durable, the LED indicators are bright and easy to see even across the garage during the day, and even the small details stand out — like the rubber feet on the bottom so the unit doesn’t scratch your toolbox or workbench. The Genius Cable Extension accessory has been AMAZING. No more struggling with clamps or leaving vehicle hoods open. Once the extension is attached to the battery posts, you simply plug the charger into the quick connect and you’re done. Super clean setup and extremely convenient. One of my favorite features is the memory setting. Once you select the battery type/mode, the charger remembers it even after being unplugged for a while. That’s incredibly useful after a power outage or if you move the charger around. I also really appreciate the thermal protection and smart charging features. During a 100+ degree day in my garage, I actually watched the charger reduce/pause charging to protect the battery from heat. Heat destroys batteries, so seeing the charger actively monitor conditions gave me a lot of confidence. I tested the maintainer function as well. Once the battery reached full charge, the indicator stayed green. Then I opened the doors and turned on the parking lights to create a battery draw. Within minutes, the NOCO detected the voltage drop and automatically started charging again. That’s exactly what you want from a smart maintainer. My personal thoughts on the models: Genius 1: Perfect for motorcycles, ATVs, UTVs, SxS, or vehicles that sit for long periods. Genius 2: Faster charging and better/more detailed status indicators. Gen5 X1: Excellent for marine applications since it’s waterproof and designed as a permanent onboard charger. Yes, these cost more than some cheaper chargers, but in my opinion, you absolutely get what you pay for. They don’t overcharge batteries, they intelligently monitor and maintain them, and the overall build quality is excellent. After owning four of them, my only regret is not buying them sooner.

Very nice product good quality.
