Paul H Lombard Jr: I have a 2006 Corvette that I converted to a lithium-ion battery from Braille.

When I did this, I wanted to make sure I had a compatible battery tender to make sure the Braille battery would stay nice and healthy during prolonged periods the car is not used. The C6 Corvette is known for battery run-down issues, and I knew this problem would be exacerbated with a lower reserve capacity battery, but I wanted the weight and space savings. I originally had a quick disconnect system in the car, the inconvenience of this became clear whenever I needed quick access to the car, so I decided to install an on-board battery tender.

The NoCo unit is very small, and lends itself to being installed in a multitude of locations. The weatherproofing helps a lot, especially if you mount under the hood. I decided to mount inside the rear compartment nearest the battery. This may be an issue for Corvettes with a full-size battery back there, but for me, since the Braille battery was already a smaller footprint, it made fitting everything inside the compartment easy.

Long story short, the unit works perfectly. The Braille battery in my car is still healthy and...

William Lim: I got this to replace my old battery charger which cannot charge Lithium battery. This one works wonderfully! 30 mins is enough to fully charge my Lithium motorcycle battery. A super fast charger that is able to charge all kind of 12V battery, all you need is just push a button to change the mode. This is my 2nd Noco product after my jumpstarter and I can say Noco never disappoint.

Machinist71: I purchased this device to hopefully remedy a parasitic drain on a vehicle that sits most of the time and I only use on the weekend as I have a company vehicle to use during the week. I kept getting in and finding that the battery was too low to even turn the engine over. After some blog reading, watched a couple Youtube videos and then diagnosed a parasitic drain on my system. In one of the blogs the author mentioned that this company's device could not only trickle charge my system while it sits all week to make sure the battery stays at an optimal level, it has the ability to condition the system to remove a type of crystal that forms inside the battery and ends up killing its performance. Armed with that, I came over to Amazon, found NOCO products and did some more research before settling on this particular one. I was skeptical, I have used trickle chargers in the past, how could this thing be different? The first thing I did was use it to charge the battery back to optimal levels. Next I used the conditioning function as I found out that when a battery discharges too many times, it causes a crystal to forms on the plates and this crystal absolutely kills...

GregB: 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.
