The NOCO Genius direct mount 2-amp smart charger quickly charges and maintains your 12V lead-acid battery, using a standard household outlet. Rated for 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.
User-Friendly Interface with LED Indicators
This Genius smart charger was designed to provide a simple, user-friendly experience. The power button allows you to easily begin the charging cycle. 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 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.
Quickly Charge and Maintain Batteries from 120VAC Power Source
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.
Rugged Weatherproof Design
The Genius2D 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.

Great product. Had 1 b4 that worked well. Had bought different brands b4 but ruined my battery. Delivered on time, packaged very well cost less than other sellers

Allison helped me find the perfect product for my need. She also helped coordinate the easy return of the previous product that was not exactly what I needed. As usual, etrailer provides outstanding products and service at great prices.

The NOCO Genius 10 is a solid, well-built product that is compact and easy to use. We are using it as a battery maintainer/trickle charger via the cigarette lighter adapter. Very pleased with this purchase!

- Smart Battery Charger for Keeping Two 6V Batteries Charged While in Storage You will not have any issues using the NOCO Genius Smart Battery Charger item # 329-GENIUS2D to keep your Airstream batteries topped off in storage. I haven't heard of any of the issues you are describing. The Genius smart charger has LED indicators that will alert you of any issues with your batteries that would cause the charger to not function correctly. Since you are charging two 6v batteries I recommend using the NOCO Genius Smart Battery Charger item # 329-GENIUS2. This system is...
view full answer... - Can I Use The NOCO Genius Smart Battery Charger # 329-GENIUS2D With A 64 Ah BatteryThe NOCO Genius Smart Battery Charger # 329-GENIUS2D is not going to work well with a 64 Ah battery. While technically it will be safe to hook up and use, it will take a very long time for the charger to fully charge your battery. Even for long term maintenance charging, this would not work well. We do recommend upgrading to a different charger like the # 329-GENIUS5, which will work with 12v batteries up to 120 Ah.
view full answer... - Recommended Battery Charger for Harley Davidson Softail HeritageGreetings, If you were looking for something that would work great to keep your Harley's battery topped off while being stored over the winter the Noco Genius part # 329-GENIUS2D is the best option as it's a 2 amp charger that's priced really great and will work well for that purpose. If you were looking for something with a higher amperage rating that will charge a dead battery quicker and can maintain a charged battery through storage the part # 329-GENIUS10 is the best option.

- Can Powerhouse TC2 2-Amp Trickle Charger Be Used for 12V Car/Camper BatteryThe NOCO Genius Smart Battery Charger # 329-GENIUS2D is suitable for 12V batteries rated up to 40 amp-hours so if the 12V battery on your camper is rated for 40 amp-hours or less, you can use it. However, most standard sized 12V batteries are going to be rated for higher than that. This particular charger has a maximum output of just 2 amps so it's going to take a really long time (if ever) to charge up a full size 12V battery if it's anything less than fully charged when hooking it up....
view full answer... - Would Dead Breakaway Battery Throw Code for OEM Brake Controller on 2018 Chevy SilveradoI don't think a dead breakaway battery would cause an error message to pop up, but that is something that would need to be addressed anyways with a charger like the NOCO Genius Smart Battery Charger - AC to DC - 12V - 2 Amp # 329-GENIUS2D or by replacing the entire breakaway kit (see attached link). Once the battery is charged up or you have replaced it that will let you know if the dead battery was for some reason throwing a code or not. If you are stilling having that code pop up then...
view full answer... - Can NOCO Genius Smart Battery Charger # 329-GENIUS2D be Used with Dual Outlet AdapterThe NOCO Genius Smart Battery Charger # 329-GENIUS2D that you referenced is designed to plug into an AC outlet and give you a way to charge batteries. If you had it plugged into the NOCO AC Port Plug with Dual Extension Cords # 329-GCP2 at same time you'd be able to use same power outlet to power the accessories you mentioned as well as still use the charger.
view full answer... - Recommended Battery Wall Charger for Two 6V Batteries on RVYou could technically use the NOCO Genius Smart Battery Charger # 329-GENIUS2D for the battery bank on your RV but I recommend using a 2-bank charger like the NOCO Genius Multi-Bank # NOC24FR instead. Reason being that sometimes more cost-effective chargers like this can get tricked into thinking the battery bank is in a good place when that first battery reaches full charge. With the 2-bank setup you will be charging the batteries separately so you know they will each be getting the best...
view full answer... - How to Activate Reverse Lockout on Boat Trailer When Moving it By Hand with a Tow DollyIt sounds like you're just needing to activate the reverse light function on a standard 5-Way connector so your boat trailer actuator will use the lockout for you to move the trailer around by hand with your dolly. I don't know of any handheld 12V power sources but you should be able to use a small battery like what you find with a breakaway kit # 50-85-313 and then wire the power only to the last pin on a 5-Way like part # HM47910 to send power to the lockout function on your actuator. It...
view full answer... - Wall Adapter Compatibility with 12 Volt Clearance LightSInce it has a single wire, it is a clearance light. You will use the mounting bracket as your ground as you stated and run 12v power to the wire. You can use a 12v marine battery connecting the negative to the bracket and the positive to the wire. If you want to install a switch like # PK34513 in line that will work well. You can use wire like the 14 Gauge Primary Wire - Yellow - per Foot # DW02412-1. If you want a converter, you can use the # 329-GENIUS2D to connect to a standard...
