I puchased this to keep the expensive type 31 batterys from sulfating on my John Deere backhoe. So far it has performed admirally. I like the fact that it has the capability to charge a totally dead battery if needed, which most other charger / maintainers won't do. I selected Noco over the brand I used to buy after seeing a comparative product review on the "Project Farm" YouTube channel.

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.

Tremendous charger. It’s next level though slightly more expensive. Worth it in my opinion. Just know that this unit has no alligator clips and only battery terminal eyelets and is a single continuous cord from the charger block to the eyelets. This is more suitable for permanent mounting than a temporary charge.

I have a 12-volt lithium battery for my truck camper setup, and I needed a way to charge it. I purchased MY 1st NOCO more than 3 years ago for my Jeep and it has worked flawlessly so of course NOCO was my 1st choice for my truck. The NOCO is inexpensive keeps my battery at full capacity with just a few hours of charge. It is super durable it stays in the dusty bed of my truck and has never missed a beat. It is super simple to use just connect the battery leads plug it in and look for the light that tells you it's charging!
