Genius GENPRO10X1: 1-Bank, 10A Onboard Battery Charger - 10A Per Bank, 12V Waterproof Marine Charger with Overcharge Protection & Temperature Compensation – for Lead-Acid & Lithium Batteries

Fantastic battery charger for a variety of uses. Have an old fashioned charger that I used for years on our vehicles on occasions when we needed. My old charger was the analog transformer style and it was quite noisy when in use. While these old chargers work fine for the occasions when you need them, they only work on the Lead-Acid style of battery found for starting engines in vehicles. Nothing wrong with that, but they cannot handle many of the newer type of battery chemistries that you can encounter. I had built my own portable power bank using a LiPo battery and needed a way to be able to charge it up. I bought this specifically for that task and it worked excellently. It charges fast and it is completely silent while in use. The smart charging circuitry is perfect for being able to adjust the charger to allow it to maximize performance and handling of the specific type of battery you are using it with. Thus it is perfect for handling both the newer LiPo batteries like I used in my power bank project, as well as replacing the older and bulkier analog chargers.

Great charger for dead batteries. Having a completely dead battery seems to be the only time I need a charger. Most require the battery to have some juice. Then, if the battery doesn't read but a volt or two, some chargers will mistake a car battery to be 6 volts and it won't charge it to 12. This one can charge a battery from zero. Worth the extra dollars. The only drawback: You must purchase battery clamps since the charger only comes with wire terminals. No problem.

I picked this up to keep a battery maintained without having to mess with portable chargers, and it’s been a solid set-it-and-forget-it setup. The install is straightforward. Once it’s wired in, you don’t really have to think about it again. It mounts clean, and the connections feel secure without being complicated to hook up. What stands out is how automatic it is. It detects the battery condition and adjusts charging without needing input. You can leave it connected and not worry about overcharging or damaging the battery, which is the whole point of something like this. Charging performance has been consistent. It brings the battery up properly and maintains it without dropping off or cycling weird. It works well for keeping things ready to go, especially if the vehicle or equipment sits for a while. The waterproof design is a big plus. It feels sealed and built for real-world conditions, not just something meant to sit in a garage. It handles exposure without any issues. Build quality overall feels solid. It doesn’t feel like a cheap unit, and everything from the housing to the wiring seems made to last. The only thing to keep in mind is it’s a single bank, so if you’re running multiple batteries, you’ll need additional units or a multi-bank version. Overall, it does exactly what it’s supposed to do. Reliable, automatic, and a good solution for keeping a 12V battery maintained without any hassle.

It's a Noco charger, it's fantastic!! These are the best IMO. So versatile with all types of batteries. Good, soild construction, and excellent CS. I own 4 chargers, plus a jump pack, and all their battery cleaning stuff. Yep, I'm a big fan of good, dependable stuff. These chargers work fast, and safety is paramount. Overall charge protection, fuse protection, and more. I just install them, connect them, and forget them! Read the directions though, good info in there about battery selection and stuff.

Compact, easy hookup, LED display clear to know battery status. Feels and looks like a very solid piece of equipment. Used for Lithium battery I would buy it again.

Works no issues

What convinced me to buy this was the fact I was disappointed with the Victron Energy Blue Smart Battery Charger with blue tooth. It depended on a Bluetooth app to see the status and the app was lame. The Victron wasn't smart enough to know the battery type, you need to go into the app to select it. Anyway I'm pointing out those negatives to point out the NOCO strengths. I liked the number of reviews for the NOCO and the simplicity of the design. This unit remembers your battery once it's plugged in and just does its thing. I like the fact the NOCO has physical selection buttons on the unit. I like that it has simple to read status lights. Very easy to mount. Good purchase. Critical grading: Value for the money- fair enough Charger Quality- well made/designed well ease of use- excellent battery charge speed- average for my lithium

Great quality use every day for a year and still going strong

Amazing! This charger really does amazing job! An older battery, that stood during the winter in a vehicle not driven for months and incapable to get a drop of juice after hours and hours of charging - in repair mode with this NOCO GENPRO10X1 was healed! After 4 hours in a "repair mode" and 6 hours of charging now is a full capacity and holds charge well. It is a proof, that what all above said from other users about this charger is true! Very happy with purchase and I would strongly recommend it to anyone. And Amazon was ultra fast to deliver it 2 days earlier than estimated, for which - thank you Amazon!

Works just fine , so far a very good charger

Friggin wicked I love this thing. Super robust plug and Play does it all. It's the best

Great unit. On initial power up, you select the battery type, then the LED's show relative state of charge with green indicating full charge. I was concerned that if the unit was unplugged, the battery type would have to be re-selected, but that appears to not be the case. Select once....and forget it! Nobody ever properly maintains a battery consistently....but this will. Bravo NOCO...truly a genius solution.

This charger is really, really built well. Thick solid alluminum case..nice heavy cords in and out. Only ran a few times so far...so I cant speak of longivity...but I dont forsee any issues.does exactly as described So far...so good
