Do more with Genius - Designed for 6-volt and 12-volt lead-acid automotive, marine, and deep-cycle batteries, including flooded, gel, AGM, and maintenance-free, plus lithium-ion batteries.

Enjoy precision charging - An integrated thermal sensor detects the ambient temperature and alters the charge to eliminate over-charging in hot climates and under-charging in cold climates.

Charge dead batteries - Charges dead batteries as low as 1-volt. Or use the all-new Force Mode that allows you to take control and manually begin charging dead batteries down to zero volts.

Simple to set up and use - Plug-in, connect to the battery, select a charge mode, and start charging your battery. A fully-automatic, worry-free battery charger for year-round use.

Restore your battery - Detects sulfation and acid stratification and restores lost performance for stronger engine starts and extended battery life.

Compatible with all types of vehicles - Charge and maintain cars, motorcycles, lawnmowers, ATVs, tractors, trucks, SUVs, boats, classic cars, hot rods, and more - you name it.

Introducing the all-new GENIUS2X4, similar to our G4, just better. It's 40% smaller and delivers 140% more power. It's the all-in-one 4-bank solution - battery charger, battery maintainer, trickle charger, plus battery desulfator.

A four-bank battery charger maintainer rated a 8-amps - 2-amps per bank with a 40Ah capacity range - designed to charge and maintain multiple vehicles like cars, motorcycles, boats, ATVs, RVs, lawnmowers, trucks, and more.

Designed for 6-volt and 12-volt lead-acid automotive, marine, and deep-cycle batteries, including flooded, gel, AGM, and maintenance-free, plus lithium-ion batteries.

An integrated thermal sensor detects the ambient temperature and alters the charge to eliminate over-charging in hot climates and under-charging in cold climates.

Charges batteries as low as 1-volt. Or use the all-new force mode that allows you to take control and manually begin charging dead batteries down to zero volts.

Automatically detects battery sulfation and acid stratification to restore lost battery performance for stronger engine starts and extended battery life.

It's not just a trickle charger; it's an advanced battery maintainer. A fully automatic, worry-free battery charger for everyday use - 24/7 - with zero overcharge. 

Introducing our most powerful lithium jump starters yet. Designed for the largest, most challenging engine starts ever. With over 6250-amps of starting power, it can jump start gasoline and diesel engines up to 45-liters.

Safe and easy to use battery jump starter pack without the worry of incorrect connections or sparks. Safely connect to any 12-volt and 24-volt battery with our mistake-proof design featuring spark-proof technology and reverse polarity protection. 

It's commercial in every way. It jump starts almost every type of vehicle and equipment, including semi-trucks (up to class 8), motorhomes, coaches, buses, mining, agricultural, construction, and vocational equipment - 6, 8, 12, and 16 cylinder - and more. Plus, an integrated digital battery voltmeter for enhanced diagnostics.
