Rugged, waterproof and it works great!
Excellent product that allowed me to resurrect 2 12v boat batteries that discharged below their minimum voltage. Installed on boat and now used as a charger and maintainer

My problem with it
My problem with it that it doesn't come with quick connect end, only with terminals. Not sure what am I going to solve this problem now as all my cars are with quick connect. Other than that, this's my third NOCO charger so it's amazing.

Excellent Charger – Easy Install & Great Battery Maintenance
I installed the NOCO GEN5X2 onboard charger in the engine compartment of my boat, and it has been a fantastic upgrade. Installation was very straightforward. The unit is compact and rugged, and it mounted cleanly in the engine bay without getting in the way of anything. Wiring was simple and well-labeled, so the whole process went smoothly even working around other components. One of the standout features is the LED indicators. I really like being able to quickly check the status of each battery individually at a glance. Whether it’s charging, fully charged, or in maintenance mode, the lights make it easy to know exactly what’s going on without any guesswork. Another huge benefit is how well it maintains the batteries during long periods when the boat isn’t in use. During the off-season, it keeps everything topped off and conditioned, which helps extend the overall life of the batteries. That peace of mind alone makes it worth it. Overall, this charger is reliable, easy to install, and does exactly what it’s supposed to do. If you’re looking for a solid onboard charger that performs well and gives you clear status feedback, this is a great choice.

Very High Quality
Fitted this in my boat, (as it has 2 batteries). It's an extremely high quality product that keeps the batteries in tip top shape via the mains. I'll be hooking it up to a solar panel next, so I'll update here when I know the results.
