Introducing the all-new GENIUS2X4, one of NOCO's most powerful, highest-performing, energy-efficient, and compact charger yet. The GENIUS2X4 is a 6-volt and 12-volt four-bank battery charger, battery maintainer, trickle charger, and battery desulfator. It's rated at 8-amps (2-amps per bank) for all types of lead-acid and lithium-ion batteries, including flooded, gel, and AGM, as well as marine and deep-cycle batteries.
  • Similar to NOCO's 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 at 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 overcharges.

From our customers


100% impressed over and over again by Jeff & Co at Revival. They’re patient and kind no matter the enquiry (currently resto-modding an R100/7 and have LOTS of questions about the Motogadget rewire) and go out of their way to offer creative solutions and out of the box thinking. I will forever return and recommend Revival.

I cannot recommend Revival Cycles enough. Not only do they have a great assortment of gear and accessories but they provide superb customer service. I was having some difficulty making it work... Jeff pointed out what I was missing and also provided schematics to make it work. Thank you guys very kindly, your crew rocks.
