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.

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.

I used this on a GMC Jimmy that had been started 2-3 in the last two years. I had gotten it to start recently with jumper cables, 2-3 hours and the battery didn’t really hold a charge. 4 hours hooked up to this, the battery is repaired and hold charge. Seems like magic! Still looking for the best place to permanently mount it in this tight engine bay.

Quality charger I did remove ring terminals and added alligator clamps for a more universal fit

This worked awesome fully charged two batteries on a 6.0 within nine hours. It might’ve been less, but it worked great highly recommend.

Good quality product works great

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 for my 570 ranger.

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

So much faster than the one I had before. This works great!!

Fast delivery, received on a Saturday! Bought it to charge the lithium battery (“house battery”, 100A/h) in my van as a backup when the alternator is not running and/or there’s not enough sun. Well built, looks sturdy. Easy to use. Works well so far. Plugged it one afternoon and the battery was full the next morning. Works for lithium battery WITH BMS.

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.
