    • Very impressed!
Size: 8A (2A per Bank)
Bought this to maintain my batteries for the boat through winter, worked perfectly! Nice compact charger, I mounted it to my garage wall above the work bench, terminal clips are moderate to heavy duty and constructed well. NOCO makes good quality products at a decent price point which is affordable.

    • Extension cables come with it for easy routing and keeps our 4 vehicles at peak charge.
Size: 8A (2A per Bank)
What a great product. We use this for our "not so often used vehicles" in our garage. We had the issue of our vehicles not being ready to drive when we wanted to take them out for a weekend spin or up to a local car show due to drained batteries. This eliminates the issue by maintaining a full charge. The multiple ports are awesome and the extension cables make routing a breeze. The size and compact design make it look great and a nice addition to our garage. I also use it for our other lawn, atv and other batteries. Simply connect and it's intelligent system detects the battery type, size and charging needs. Shuts off automatically and will turn back on if it detects a voltage drop. Love this thing! ... show more

    • Great quality - You get what you pay for!
Size: 8A (2A per Bank)
Full disclosure, we use other Noco chargers onboard our school buses at our kid's school. They are very robust and keep the dual 12V commercial batteries fresh when the buses are not in use. I got this one for my motorcycle fleet(?) at home. Yes, the charger is more expensive than several similar. It's worth it. I've used Battery Tenders, and many others over the years. The Noco is best. The leads for the battery are not the standard SAE version. Noco uses a heavier duty connection that clicks into place. The alligator clips are designed to be removed if you need to permanently install a lead on your vehicle's battery inside your car. The unit comes with clear instructions. If you are upgrading for an existing SAE configuration, get the Noco-SAE adapter ($16 at this time). Just search in Amazon "NOCO GC009 X-Connect SAE Adapter Accessory Genius Smart Battery Chargers" . ... show more

    • Dependable & Dynamic: Exploring the NOCO GENIUS2X4
Size: 8A (2A per Bank)
I recently started using the NOCO GENIUS2X4 for charging and maintaining multiple batteries, and it’s been a reliable addition to my workshop. With four separate banks delivering 2A each (for a total of 8A), I can work on several batteries at the same time without worrying about overloading any single unit. The smart charging feature adjusts the current to suit different battery types, making it both efficient and safe. The build quality is solid, and the compact design makes it easy to store or transport. Overall, it's a dependable charger that has streamlined my battery maintenance routine, whether I'm dealing with car batteries, power tools, or other rechargeable equipment. ... show more

    • Works great. Easy to use. Does the job.
Size: 8A (2A per Bank)
I was persuaded to but this unit by the salesguy in Autozone and they dont even stock it (or didnt at this MA location)! He said he uses it and loves it. I took his advice and bought it on Amazon, even thought its relatively expensive compared to some other chargers. Its worth every penny! It can charge up to four batteries at once, clearly indicates (via LED lights) where it is at in the charging process, will not over charge and then (the best bit) keeps the batteries at peak charge, all the time, automatically. I am using it to charge two RV batteries and a yard tractor battery over winter. I love it. I literally just attached the batteries and walked away knowing they will be in great shape this spring. Aaah, peace of mind. Enjoy!! ... show more

    • Very nice charger except for....
Size: 8A (2A per Bank)
This is a really nice charger. Each bank has its own power button and battery selector. So you can charge different batteries at with the same charger. The ONLY reason I didnt give it 5 stars is because it only came with alligator clips. Its an on board charger and should have come with pretty wired pigtails to mount to each battery. It does come with several different power cords, so if youre buying this from outside the USA, you wont need to purchase a separate adapter ... show more
