Meet our most powerful, energy-efficient, compact portable universal battery charger to date: the GENIUS1. The GENIUS1 is a 1-amp (15-watt), 100-240VAC 50-60Hz heavy-duty 6-volt and 12-volt battery charger/maintainer/trickle charger/float charger and desulfator capable of charging batteries up to 30 amp-hours in capacity.

• It was designed to charge and maintain all types of sealed lead-acid and lithium-ion (Lifepo4) batteries, such as flooded, gel, maintenance-free AGM SLA VRLA AGM automotive marine RV powersports deep cycle batteries.
• Advanced Battery Regeneration Mode Using Slow Pulse Reconditioner Technology To Automatically Detect Sulfation And Acid Stratification It uses slow pulse reconditioner technology to automatically detect battery sulfation and acid stratification, and restore lost performance for increased lifespan of batteries.
• Home, garage, mobile bench or even in your vehicle - anywhere that allows access to 12V auxiliary cigarette lighter port! Ideal for maintaining any battery! Next-gen charging regime employing fast charging microprocessor technology allows it to quickly recharge batteries without manual intervention, creating a completely worry-free intelligent battery charger with zero overcharge potential. 
• These durable covers were made for both indoors and outdoors use - providing weatherproof and waterproof protection from all four seasons, including winter. These advanced battery connectors from X-Connect allow for quick-connect permanent connection or directly linking directly to battery terminals for easy quick use.
• Digital displays provide battery charging status and diagnostic tests to detect conditions like dead battery, bad battery, reverse polarity and more. And it works with virtually every type of gas and diesel vehicle on the road today, from cars and Meet the GENIUS1: the perfect combination of size and power! Comparable to our G750 but 35% smaller and with over 35% more power output.
• An all-in-one universal charging solution featuring battery charger, maintainer, trickle charger, float charger and desulfator all in one compact device!
  Genius can do more for you - it is designed for 6-volt and 12-volt sealed lead-acid batteries used in automotive, marine, RV, powersport and deep cycle applications, including flooded, gel, AGM, SLA VRLA maintenance-free batteries (and lifepo4) as well.
• 
  Experience precision charging - An integrated digital thermal sensor detects ambient temperature and modifies charging accordingly to avoid overcharging in hot climates or undercharging in cold ones.
• 
  Charge dead batteries - Our device charges batteries as low as 1-volt. Additionally, use our all-new Force mode for manual control over charging dead batteries down to zero volts.
• 
  Restore Your Battery - An advanced battery repair mode uses slow pulse reconditioner technology to detect battery sulfation and acid stratification and restore lost performance for stronger engine starts and longer battery life.

Beyond Maintenance - Not simply a trickle charger, this advanced battery maintainer offers worry-free charging throughout the day - 24/7 with zero overcharge!
Compatible with All Gas and Diesel Vehicles - Charge and maintain cars, automobiles, motorcycles, dirt bikes, scooters, mopeds, lawn mowers, ATVs UTVs tractors trucks SUVs RV campers trailers boats PWC jet ski snowmobile golf cart classic cars etc.
