GENIUS2X2: 4A 2-Bank Smart Battery Charger (2A/Bank) - 6V/12V Automatic Maintainer, Trickle Charger & Desulfator with Overcharge Protection & Temperature Compensation – for Lead-Acid & Lithium

Fantastic product. This works especially well if you have a dual battery setup and you no longer have to remove the terminals to individually charge each battery insuring they get the proper charge. Easy to read battery status. I have not noticed any heat coming off of the unit or noise even with both charging operations in use. Also works to dissimilar batteries in a vehicle i.e. Lead acid-Lithium as you select the type of battery you have to be charged. The extensions are enough to keep two vehicles parked side by side in a garage/outside charged and topped off. Not only works well to recondition and charge a dead battery but is a maintainer you can leave on the battery 24/7 This is one of the best chargers I have ever purchased and it gets a lot of use with all of my vehicles especially in cold harsh environments. I have a NOCO single charger that I really like but this is now the one that gets the most use. Well worth the purchase.

Love noco tenders. Works as advertised, feels quality in the hand. The length of cables is really nice.

The NOCO GENIUS2X2 has been an excellent addition to my garage. Being able to charge and maintain two batteries at the same time is a huge convenience, especially if you have multiple vehicles or seasonal equipment. Each bank operates independently, so you can connect different batteries without worrying about interference. Setup was straightforward, and the included cables and clamps feel high quality. The smart charging features are where this unit really stands out. The temperature compensation works exactly as advertised, adjusting automatically based on ambient conditions, which gives confidence when leaving it connected long-term. I’ve used it in both cold and warmer conditions with consistent results. One of the most impressive features is its ability to recover deeply discharged batteries. I successfully brought back a battery that I assumed was beyond saving, and the desulfation function seems to have genuinely improved performance afterward. It’s reassuring to know the charger actively monitors the battery and prevents overcharging, making it safe for indefinite maintenance. Overall, this is a well-designed, professional-grade charger that delivers on its claims. If you need a dependable two-bank charger for cars, motorcycles, lawn equipment, or marine batteries, the GENIUS2X2 is absolutely worth the price.

This is a great charger, works great, i have it mounted on my work bench

I have a big stupid truck in my driveway that I barely drive anymore. It’s a diesel with two batteries. When I do need it, the batteries are usually dead from sitting so long with a minuscule power drain. I put the NOCO 2-bank charger on it, my batteries recharged, and I leave it float charging until I need the truck again. The display ensures your batteries are charging, what state of charge, and when charging is finished. Elegant solution. Much simpler than dragging out the shop charger and having the hood open for a day. The car collector guy down the street swears by NOCO. Add me to the list of fans.

Works good but not water proof

Great product. I rarely give out 5 stars. I have 3 cars and dont drive often so keep two of the cars on the smart charger. This is an advanced trickle charger with the ability to recover a dead battery by delivering strong pulses of energy. The charger has good heat level. Small in size but very powerful. Easy to use. comes with cables , clamps. I also purchased cables to attach to my batteries so I dont have to pop the hood, just a quick disconnect.

Good tender. After using the other major player for years, it ruined a new battery over the winter. Displayed a green light but battery was 9.3 V and would not recover. Switched to NoCo and have had no issues.

Universal mc charger , does it all 2 at a time = ’nuff said 🤙

Jamais déçu par ce produit! J’en avait déjà un pour une seule connexion et il m’en fallait un second det mon choix c’est porté vers cette marque ! Très bien 👍

Highly recommend
