Specs:
The NOCO Genius 2-amp smart charger quickly charges and maintains your 6V and 12V lead-acid and lithium-ion batteries, using a standard household outlet. Rated for 6V and 12V batteries up to 40 amp-hours, it's a great charger for ATVs, wave runners, lawn mowers, and other equipment. It's also ideal for daily battery maintenance or long-term storage of cars, boats, trucks, and RVs. With 4 selectable battery profiles, multi-stage charging, and advanced safety features, this Genius smart charger makes it easy to keep your batteries in peak condition. There's even a Force Mode feature for charging dead batteries with 0-volts.
This Genius smart charger removes the frustration of having to own multiple devices to charge different battery types and vehicles. Just attach the battery clamps to the vehicle's battery terminals, select a charging mode to match your application, and wait for the LED indicator to signal that the battery is completely charged. It's that simple.
This Genius smart charger was designed to provide a simple, user-friendly experience. The mode button allows you to easily cycle through the unit's charge settings. Back-lit LED indicators let you verify that the unit is operating correctly, and they allow it to be easily operated at night. These indicators signal the unit's charge status, selected charging mode, and alert you to potential performance issues or errors.
This allows you to identify if the battery voltage is too high or too low for your selected mode, or detect a reversed polarity connection to a battery.
This Genius 2-amp smart charger has 5 selectable charging modes that let you quickly switch between charging different lead-acid and lithium-ion battery types at different voltages. Traditional battery chargers generally only work with a specific voltage or battery type, like lithium-ion or AGM batteries, or only in special circumstances like charging in cold environments. This Genius smart charger gives you the versatility to tackle different battery types and charging situations in one charger.
The image above details the available charging profiles. The charger works with 6V and 12V wet cell, gel cell, enhanced flooded, calcium, maintenance-free, AGM, and 12V lithium-ion batteries with battery management systems (BMS).
The Genius 2-amp can detect and charge batteries that have been drained to 1-volt. And by activating the Force Mode, the charger can even charge dead batteries with 0-volts. Traditional chargers can't detect a battery when the voltage drops below a certain level. To activate Force Mode hold the mode button down for 5 seconds.
The needle-nosed battery clamps included with this Genius smart charger are designed to easily connect to battery terminals of all shapes and sizes. Unlike typical, plastic battery clamps, these clamps are constructed entirely of metal, ensuring maximum conductivity. The clamps are covered with an over-molded plastic housing, which makes them easy to operate even with work gloves on. A built-in 10-amp fuse protects your connection against dangerous overloads.
1/4" Eyelet connectors can be unbolted from the clamps for direct mounting to terminals on hard-to-reach batteries. The lie-flat design ensures maximum contact with terminals to optimize current transfer.
This Genius smart charger plugs into an available wall outlet to quickly charge and maintain your battery. High-frequency switch-mode technology converts AC power into safe DC power to fully charge batteries. An onboard microcomputer monitors and controls this charging process to minimize power loss and maximize efficiency. The included mounting bracket with hook-and-loop strap lets you mount the unit in an enclosed compartment, garage, or workspace.
The table above provides a quick reference for how long it will take the unit to charge some different battery sizes.
The Genius2 smart charger comes with over-molded connection points to protect the unit from dirt, dust, and water. The unit has an IP65 rating, meaning the housing is considered "dust tight" and protected against water sprayed from a nozzle. A durable X-connect plug ensures a weathertight connection when attaching the clamps to the charger.
The housing is made from tough Lexan resin that protects the internal electronics against impacts. The unit can handle being dropped, kicked over, and just about anything else your day brings.
This Genius smart charger features a unique X-Connect plug that lets you disconnect the battery clamps and attach other X-Connect accessories (all sold separately) for versatile plug-and-play charging solutions. Add an extension cord to increase your connections reach, or use the 12V female plug to connect and power 12V accessories. Access your vehicle's battery through charging ports with the OBDII connector, or the 12V male plug. With a large variety of available accessories this battery charger can be outfitted to meet your application's specific charging needs.

Hey everyone, I'm Ellen here at etrailer.com and today we're taking a look at the NOCO genius battery charger and maintainer. This is going to help us keep our batteries charged and ready to go whenever we are to go out on our adventure, get some work done around the house, or whatever the case might be. It's going to allow us to charge and maintain the batteries for 6V and 12V batteries have a lot of different types, we'll go over those in a minute, but it's going to be just as nice compact systems. You can mount this to the wall, keep it in a drawer or your toolbox anywhere close at hand, to make sure that those batteries are maintained and ready to go. Just plugs into the wall AC plug there nothing too fantastic or special about that. On either end here, we'll have the connections to get our accessory plugged in.A lot of the NOCO staff will use the same plug so you can kind of reuse and switch and swap them out, then our little alligator clamp is going to go on the battery terminals.
Pretty common you see these on just about any kind of jumper cable or anything like that, red goes positive, black goes to the ground or negative. We do have a little keeper, this is going to mount to the wall or somewhere safe at hand, maybe the side of your toolbox to keep this nice and up out of the way, basically just wraps around the body of the charger kind of snaps in place, so you can keep that up and ready to go. And see that snaps around there can put the hook a little strap around and now hanging it against the wall does come with two small screws to attach that bracket to the wall, so you can have it wherever you want it.As far as what this will work with, as I mentioned, a lot of different battery types, 12V and 6V, got wet cell, gel cell, in advanced are enhanced flooded, maintenance-free AGM and lithium.So just about any small vehicle, you have tools, things like that, that you need to charge up with this. You can do that. Even if that battery is completely depleted, you can put this into force mode and then that will bring that battery back to life, even if it's down to zero volts.
So that's a pretty nice thing. The way it will be able to change those modes is going to be this button here. It's a pretty nice screen to let us see what's going on with our batteries. So you can see what sort of mode you have it in. Also check the charge and swap everything out.
So easy to read, LED system there.Pretty self-explanatory as I mentioned with the clamps going around your batteries, this does have a multi-stage charging and algorithm as well, so that's going to typically charge batteries faster than the other battery chargers you see in the market about two times faster, so should get everything back up to operational quickly. It's also going to have thermal sensors, so it's going to adjust that ambient or the charging performance per the temperature, and also the housing is made out of a Lex and rexine, so it's going to be nice and rugged up to, up to the task for hanging out in the shop and maybe getting banged up a little bit without too much issue.It does have an IP 65 rating, so dust proof, and it can be splashed with water without any real adverse effects, of course, you don't really want to have any of the electrical connections anywhere near water, but the box itself should be able to stand most shop environments without any issues. Those connections here, this is going to be the X or X connect series. That's what these connections are called, has little Xs on them, so pretty easy to plug in and take apart. A lot of the NOCO staff has those, and then whenever you're not using them has a little plugs to go over them, to keep those protected.As far as the size of our charger, it's going to be about 5 inches by 3 inches and then an inch and 5'8 thick, the AC cable measures 72 inches long.
Our connector cable measures 56 inches, and then the clamps are going to have a length of 21 inches. The max charge that this is rated for the max charging amperage is going to be 2 Amps, and the max power consumption is going to be 30 Watts. That's pretty much all there is to it for this does have a 3 year limited warranty, I think this will make a great accessory to keep all those items charged up and ready to go so that you don't have to wait on getting your work done around the house or getting out on the road and enjoying your life.But that's going to do it for me, I again I'm Ellen here at etrailer.com, hopefully this video has helped you in deciding if this is going to be the right product for you, if not, we do have other options available here so check them out. Thanks for watching.

Compact smart charger draws power from a wall outlet to charge and maintain batteries on cars, RVs, boats, motorcycles, ATVs, snowmobiles and lawn mowers. Force mode revives dead batteries. Charges lead-acid and lithium-ion batteries.
Very good quality, this is the fourth one I own, highly recommended
Ferris - 06/04/2022Just added this one to my “fleet” of NOCO chargers, has kept my group of Antique tractor 6 volt batteries alive for several years instead of replacing them almost every year. I don’t and won’t own anything else! They are the best!
I bought two of the Noco 2 amp battery maintainers and am pleased with both. Using them outside in a dry location to maintain car batteries. Convenient connect/disconnect and easy to read and understand status LEDs.
Having used THE NOCO Genius2 battery charger for greater than 1 years, I can say that I am completely satisfied with form and function of the device. I use the charger to maintain fresh battery charge for my RV trailer. I like the compact, portability and weight of the unit. The indicator lights keep me informed of the battery charge status. I consider this purchase as one of my best purchases of all my RV gear. Thanks for an excellent product.
Works as advertised. Quality product, simple operation. Especially like how the system remembers the last battery type setting for each of the 4 banks of chargers. I bought several more Noco chargers after this one.
When I got the charger the switch wasn't working so I contacted customer service and a new unit was shipped right away. Got my new one hooked up and it's working great. Great service!
Because of great demands on marine batteries these days with electronics and trolling motors, it is important to maintain their voltages when not in use. The Noco Genius Smart Battery Charger-2 amp not only charges the battery back up but also maintains it so you are always ready to go. Built for marine conditions this little charger takes up miniumum space and is easy to use with nicely made gator clips and a long detachable cord making connecting time a snap. Bright LED lights let you know where this trickle charger is in the cycle and flashes a green light when done and in maintenance mode. The instruction booklet is helpful but use a magnifier to catch all the details in the fine print. Everyone needs this little device to keep 12 volt batteries fresh and ready to go and e-Trailer has one for your car or recreational need!

This charger has served me well to keep my motorhome batteries charged.
Andy S - 04/30/2022Review from a similar NOCO Genius in Battery Charger
Works as advertised. Have used it to restore a 12v lithium 100ah battery which was allowed to go well below the recommended level of discharge. The compact size is also a big plus.
Review from a similar NOCO Genius in Battery Charger
Contacted etrailer.com about charging K2 Energy Lithium Ion marine batteries. They took the time to contact NOCO Genius chargers to get me the correct answers. NOCO said absolutely that this would be the correct charger for lithium ion marine batteries.
I am now confident that my investment of Lithium batteries will get the correct charge they require. The NOCO genius charger is lighter and smaller than my previous charger allowing more room and less weight in my boat.
Review from a similar NOCO Genius in Battery Charger
We have had this charger for about a year now. We use it to recharge batteries for the camper and boat, and maintain them over the off season. It has worked great to charge both our conventional wet cell and AGM 12 volt batteries. It charges the batteries in a reasonable amount of time and, due to the "smart" multi-stage charging technology built into the charger, we do not have to worry about over charging the batteries. I highly recommend this charger.
Review from a similar NOCO Genius in Battery Charger
pretty expensive for a trickle charger, BUT it appears to be made from better than average materials, and it is compatible with wet cell, AGM, and even Li-ion. The battery clamps are really nice-looking, quality constructed, top grade material. It appears to me to be a really top shelf, state of the art, highly-optioned, trickle charger. 3yr warranty.
Fred G - 04/17/2021Review from a similar NOCO Genius in Battery Charger
Wow! Your delivery and tracking system is excellent, very personal and accurate. My new battery charger is here and currently (yes pun intended) in use on my RV.
Review from a similar NOCO Genius in Battery Charger
8 months after purchasing my NOCO Genius the battery on my truck went dead, best I could get was a little clicking, no lights, radio, nothing. My first thought was a lose connection however after checking and finding everything in order I hooked up the NOCO, turned it on and fired the truck right up. This was my first experience with this type of device and did not know what to expect, I was completely impressed by how well the NOCO Genius worked! It is a must have and will always be a part of my onboard took kit!
Review from a similar NOCO Genius in Battery Charger
Excellent selection of products, great prices and fast delivery. Can't beat etrailer website for service.
Review from a similar NOCO Genius in Battery Charger
I like that it's weather proof and has selectable charging. It charges car batteries quickly, but I mostly use it to charge the chassis batteries in my motorhome while it's in storage. The only negative I've found is that it doesn't handle Arizona summers, but I haven't found a charger that does. I use it for a few hours early in the morning and that seems to be sufficient. I installed the NOCO eyelet terminal accessory on each set of batteries.

Very fast delivery, product as described, another great experience with etrailer. Thanks!

heavy duty, really solid product, can tell its built with quality
steve - 10/25/2021Review from a similar NOCO Genius in Battery Charger
The Noco G1100 is one of four items I purchased from etrailer to make a portable 12 volt power pack for camping. I wanted to make my own power pack because many available do not have the power I want, have gimmicky features I do not want, and the batteries are not usually user-replaceable. Noco’s X-connect feature made this very easy. I also ordered a HM082BKS box for a U1 type battery, a GC010 12 volt female connector (cigarette lighter type), a GC013 male-to-male coupler, and a GC004 10 foot extension. From elsewhere I purchased a 35 amp/hour U1 battery with screw terminals (Interstate DCM0035) to fit in the box. I unscrewed the battery clamps from the charger output cable which left ring terminals I then attached directly to the battery. Leaving this part attached to the battery, the X-connect feature allows me to: (1) hook up the charger to the battery, or, (2) with the GC013 coupler, attach the female connector for camping. I expect to use this power pack for my CPAP, which can run directly from 12 volts DC (without an inverter), and eventually other items, such as a 12 volt TV. I can also power and charge USB devices with a USB adapter/charger which plugs into the 12 volt female connector. I’ll be testing the setup during an upcoming trip but have no reason to doubt it will work as expected. Of course, you could do the same thing with a bigger battery with the proper charger and battery box. The X-Connect feature is great and I should not have to open the box until I need to replace the battery.
I have attached pictures which show (1) the charger attached to the battery, (2) 12 v female connector connected to the battery with the male coupler, and, (3) the unit ready for travel. The little dust cap from the X-Connect is attached to the battery box strap.
