Ultimate versatility.

Eight battery chargers in one.

Other brands require a separate battery charger for 12V charging, 24V charging, AGM batteries, for cold conditions, lithium-ion batteries, and battery desulfation. Have peace-of-mind knowing that as your needs and vehicles change, your versatile multi-purpose charger can stay the same. With a simple push of a button, you'll have the power to switch between various charging modes within one complete battery charger. And it's equipped with a progressive repair method for recovering heavily sulfated and weak 12-volt batteries.

12V Automotive Car Battery Charger with Battery Desulfator

12V Repair Mode

A progressive battery recovery method for improving heavily sulfated and old 12V batteries that restore lost battery capacity.

12V Automotive Car Battery Charger for Powering a Tire Inflator, Power Inverter and More

Bigger is not better.

It’s time to retire your grandpa’s battery charger.

Our next generation smart battery chargers utilize the latest advancements in battery charging technology. These switch-mode battery chargers were built on a high-frequency and high-efficiency platform, which converts energy 30,000 times faster than traditional automotive battery chargers. This efficient use of electricity is what makes our chargers compact, lightweight, and incredibly portable. Our chargers minimize energy consumption, and are compliant with California Energy Commission regulations.


Safe to leave connected with zero overcharging.

Most manual, automatic or semi-automatic battery chargers continuously trickle charge batteries. Traditional chargers are susceptible to overcharge, thus limiting battery life. Our intelligent battery maintenance technology monitors battery activity, and only begins charging when needed. This system allows for continuous operation without user intervention, and zero risk of overcharging your battery.

CANbus enabled.

Charge batteries directly from the 12-volt port.

CANbus electrical systems found on BMW, Ducati, Triumph and Harley-Davidson motorcycles disable the 12-volt charging port when the ignition is off. Recharging requires the ignition to be on, or direct connection to the battery. With CANbus enabled technology our chargers send a unique voltage signal that automatically opens, and allows charging through the 12-volt accessory port.View The CANbus Dual 12V Plug Accessory


Battery maintenance made easy.

Plug-in, set and forget. It's no wonder Genius is the ultimate battery maintenance charger. Quickly connect and disconnect the battery charger when needed. It remembers the last charging mode used, and automatically resumes charging after disconnection or loss of power. The G7200 keeps any battery fully charged without supervision.

12V 24V Portable AGM Deep Cycle Car Battery Charger Maintainer with Auto Memory Feature


The G7200 remembers the last charge mode when accidentally unplugged or loss of power. You'll never come back to a dead battery again.

12V 24V Portable AGM Deep Cycle Car Battery Charger Maintainer with 5 Year Limited Warranty

5 Year Warranty.

Our battery chargers are built to last. That's why we back it up with an unbeatable warranty, combined with unparalleled customer service.

Advanced diagnostics.

Battery charging with intelligence.

Smart battery chargers can be frustrating. It won't simply begin charging if it detects a weak or damaged battery, or force charging if it detects an unsafe or abnormal charging condition. However, prevention is just one aspect. Understanding and finding a solution is just as critical. Welcome to Advanced Diagnostics, which analyzes battery feedback and display a particular error pattern if a problem is detected. Each flash pattern tells you what's wrong, and how to quickly fix it.
Single Flash: Battery will not hold a charge and should be checked by a professional.
Double Flash: Possible battery short, and should be verified by a professional.
Triple Flash: Battery voltage is too high for the selected charge mode. Double check the battery matches the charge mode.
Error LED Solid Red: Reverse polarity. Reverse the connections to the battery.
Standby LED Solid Orange: Battery voltage is too low for the battery charger to detect the battery.

Battery Charging vs. Battery Maintenance.

Which battery charger is right for you?

Selecting the proper battery charger depends on your needs. Do you need to recharge a dead battery entirely, or just keep a battery at full charge? Battery charging means you need to recharge a dead battery fully, whereas battery maintenance requires a mere trickle charge. Most battery chargers perform both functions, but understanding their limits and the amount of time to recharge depends on the size of the battery and vehicle. The G7200 is designed for charging smaller applications, like a motorcycle, ATV, snowmobile, or lawn and gardening equipment. It's also a perfect battery maintainer for a car, boat, RV, or truck. The charging time chart not only helps you determine how long it will take to recharge, but also its limits between battery charging and battery maintenance.Why maintain your batteries?

Efficient design.

Compact, yet powerful battery charger.

A mix of electrical engineering and industrial design creates a powerful battery charger in a tiny footprint. It uses high-frequency switch-mode technology to efficiency convert A/C power into safe D/C power for battery charging. The G7200's onboard microcomputer precisely controls the charging to minimize power loss to create an incredibly compact form factor.

More ways to charge.

The possibilities are endless.

Permanently mount eyelet connectors on multiple vehicles to make hard-to-access batteries easy to charge. Charge directly through the 12V auxiliary or OBDII port from inside a vehicle, or just extend the reach of your accessories. Whatever the case may be, our interchangeable X-Connect battery accessories create a reliable weatherproof connection that not only provides maximum current flow, but also allows for fast and easy accessory changes.View All Battery Charger Accessories
