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 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 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 note they 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.

Wow! Great Parts and easy connections. Plugged in and it worked without fooling with it.

The best battery charger and maintainer I’ve ever had. It literally brought back many of my old batteries that I thought were on usable. It actually reconditioned the battery in a second vehicle. I rarely use and saved me from having to buy a new battery. Highly recommend this it’s worth the higher price.

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.

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

NOCO chargers work Great, I have several of them. This one works great in the garage with the extension cords to drop down from above and hook up to the UTVs.

This is an excellent maintenance charger for multiple types large batteries. If you have an agm type car battery this is ideal. I have many small maintenance chargers but they are all made for the older standard lead/acid batteries. There is a difference! I have two of these now. Excellent quality. A must have in Michigan winter. Extends battery life.

Très bien, bon rapport qualité-prix, produit top qualité.

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

Motorcycle is on trickle charge as it is not used during the winter. Months. Works a treat. Recommended

Das Gerät benutze ich um auf einem Segelboot sowohl die Starterbatterie als auch die Versorgungsbatterie zu laden bzw. zu erhalten. Am Gerät fest angeschlossen ist eine 80 AH Nassbatterie und ein 100 AH Gelbatterie. Für die Erhaltung/Ladung der Starterbatterie ist das Gerät absolut ausreichend, ich brauche die Staterbatterie nur um den Diesel meines Seglbootes zu starten. Mit dem Gerät ist die Starterbatterie jederzeit voll geladen. Wenn ich die Versorgerbatterie (100 AH Gel) während eines Tages auf dem Wasser sehr beansprucht habe, also ca. 75 AH Stunden entnommen habe, dann läd das Gerät sie bei 2 A Ladestrom naturgemäß über Nacht im Hafen nicht vollständig. Für diesen seltenen Fall habe ich noch ein stärkeres Ctek an Bord. Ansonsten ist das Gerät fest verbaut, die Batterien sind fest angeschlossen und ich muss mir keine Gedanken um etwas machen. Die Verarbeitungsqualität , Gehäuse und Zubehör, ist deutlich besser als bei den CteK Geräten die ich besitze. Ich kann das Gerät für jemanden der gleichzeitig 2 Btterien laden/erhalten will und nicht auf hohe Ladeströme angewiesen ist nur empfehlen.
