    • Versatile, Reliable, and Worth the Investment
Size: 4A (2A per Bank)
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. ... show more

    • Efficient and Versatile
Size: 4A (2A per Bank)
The NOCO GENIUS2X2 is a highly versatile and efficient battery charger and maintainer that proves to be an essential tool for automotive enthusiasts and professionals alike. This 2-bank, 4-amp charger (delivering 2 amps per bank) is suitable for charging 6V and 12V lead-acid and lithium-ion batteries, making it a great fit for a variety of vehicles from motorcycles to ATVs. One of the standout features of the GENIUS2X2 is its ability to act not only as a charger but also as a maintainer, trickle charger, float charger, and desulfator. This multifunctionality ensures that batteries are not only charged but maintained in top condition, helping to extend their lifespan significantly. The desulfation mode is particularly noteworthy for its ability to rejuvenate underperforming batteries, a feature that sets it apart from many competitors. The smart functionality of the GENIUS2X2 allows it to automatically detect the battery type and condition, adjusting its charge accordingly to prevent overcharging or undercharging. This feature is highly beneficial for those who may not be very familiar with the specifics of battery care, as it minimizes the risk of damaging the battery due to user error. The unit itself is compact and robust, designed to be durable and easy to use. The interface is user-friendly, with clear indicators and minimal setup required, which is ideal for those who prefer a plug-and-play solution. Additionally, its safety features, such as spark-proof technology and reverse polarity protection, provide peace of mind, making it a safe choice for all types of users. In terms of improvements, while the GENIUS2X2 performs exceptionally well in most scenarios, some users might find the 2A per bank output slightly limiting if faster charging times are needed for larger batteries. However, for regular maintenance and charging of standard batteries, this output is typically adequate. Overall, it’s a good recommendation for anyone looking for a reliable, smart battery charger that can handle multiple types of batteries with ease. Its combination of versatility, ease of use, and intelligent charging features makes it a worthwhile investment for maintaining the health and longevity of your vehicle batteries. ... show more

    • Saved me lots of money protecting my batteries!

These things are money savers by protecting the battery life of all my equipment. I have these on my zero turn mowers over the winter, bobcat skid steer and my polaris side by side utv.

    • Can handle two batteries at once
Size: 4A (2A per Bank)
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. ... show more

    • Great Product! (Update - Not So Great In The Long Run)
Size: 4A (2A per Bank)
Further update... 2 weeks later, a third charger has now failed. I contacted NOCO and all they would do is offer me a 10% discount code on a future order (only one item must be in the cart for the discount code to work). Not at all pleased with the customer service and the fact that these units seem built to last until the warranty runs out. My initial praise of these has fallen to utter disappointment. The company should stand behind their products better than this. Update... I gave these chargers rave reviews as seen below, but now not so sure. Although I still like these trickle chargers, 2 of the 5 I have purchased have gone bad within approximately 3 years of purchase. A third one had only one bank working on it when received and the seller would not exchange it or give a refund. After contacting NOCO, they offered me a coupon worth 10% off my next purchase. Kind of disheartened with the life of the chargers and the customer service. Maybe should be looking for another more dependable brand. I bought 3 these on sale, but honestly after getting and using them, they are worth the price even if not on sale. I have several 4 wheelers and bought new batteries for 3 of them. One of them sat unridden for almost a year and the battery was completely dead. These units brought it back to life just like brand new. That saved me $100 on another battery purchase, which more than paid for one charger. It also keeps another 7 year old battery fully charged. These things work! ... show more

    • Crap connectors
Size: 4A (2A per Bank)
This would be five stars but they decided to have their own connection type. Not the usual that most manufactures use. I had to change the ones already installed on my batteries. Not too difficult but a pain and unneccesary. Their connections are not as tight as the normal battery tender connections. Besides the connectors the unit seems solid. ... show more

    • Best charger I have
Size: 4A (2A per Bank)
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. ... show more

The battery charges are great, just as expected. But the driver, Dontres, was amazing. It was a large, heavy order and he pulled it off like a pro…and would accept no help. He is an asset to Amazon for sure!
