NOCO 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

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.

This charger works! It remembers what setting for battery type, so when you plug same battery in again you don't have to change settings. Unbolt the battery clips and it leaves you with ring terminals that you can leave attached to your battery. Both ends of plugs have a cover to keep dirt and debris out of plugs when not used. This also has an automatic battery conditioner that detects when its needed. Simple easy to read indicator lights to see condition of battery charge. This is my second unit, was so happy with my first.. High quality product, for a reasonable price. Side notethey sell an adapter plug that connects to plug left behind on battery. It enables a usb cord to be used to charge cellphones ect. This is perfect for my motorcycle without a charging port.

I use this to keep my motorcycles charged while I’m not using them. Works perfect. Can use them on several battery types such as regular lead acid, gel AGM, or lithium. Waited to get them at a good price.

Great chargers with all the included accessories. This is my second one after 5 years. (first one wouldn't always recognize the battery on the left bank)I have the same batteries in two new jet ski's I bought 5 years ago that have zero issues or need of replacement far and beyond the recommended 3 year lifespan.These devices repair and keep the battery perfect. I have them directly connected to the battery and just set and forget.

I decided to buy a Noco Genius 2X2 2-Bank battery charger/maintainer after my Battery Tender quit (out of warranty of course). When the package arrived, I was super impressed with the packaging which reminded me of a new Apple phone. I was used to the cheap Battery Tender impossible to open packaging needing a razor knife to cut open the plastic. Once I opened the Noco I could see the superb quality of the unit and the battery clips. This is way better than the Battery Tender I was accustomed too. The unit is designed to be mounted and comes with 2 mounting screws. It also includes wiring extensions, so you are not stuck hanging long wires if you don't need the length. The wires make a nice snap noise to let you know the connection is solid. The battery clips are larger and very nice quality.Note the unit only comes with a 3-year warranty.My only complaint is they include 4 sets of beautifully crafted plugs for not only the US, but also for the EU, UK and Australia. To cut down on electronic waste I would suggest offering different models in different parts of the world. Probably cheaper to just include all the sets, I guess. Oh well, if I move to the UK or elsewhere, I'll be covered! I am super happy with the product and would highly recommend it.

I love noco products I have jump start,battery chargers,noco battery’s LP30 LP 20..only thing was missing in this unit is motorbike Conection,this unit comes with 2 clamps.over all very well made,easy to use

been hooked up for a few weeks now no issues keeps both my motorcycles charged. one is a lithium battery one is a normal battery and it remembers when you hook it back up amazing product!!!!!!!!

I have two motorcycles that get equal riding time, and I was tired of having two trickle chargers. Another issue is having two types of batteries, and one of my older chargers couldn't accommodate newer battery types. This charger, while a little expensive, is a thing of beauty. I also purchased the adapters and long cables I needed. I mounted this to the wall between where I park my bikes, plugged them in, and let it do its thing. I highly recommend this as it's a quality piece of equipment.
