Multi-voltage, multi-chemistry, multi-battery type
The GENIUS2X4 charges 6V and 12V lead-acid and lithium-ion batteries across a wide range of chemistries — flooded, gel, AGM, EFB and maintenance-free — and battery types including starter, deep-cycle, marine and powersport. All four banks operate independently, so you can mix voltages and chemistries at the same time.
Powerful, efficient and compact
High-frequency switch-mode technology converts AC power to safe DC power efficiently, while an onboard microcomputer controls charging precisely to minimise power loss. The result is a capable charger in a compact form factor.
An improved start-voltage sensor lets the GENIUS2X4 detect and charge batteries as low as 1V. For batteries below 1V, force mode can be activated manually to charge all the way down to 0V.
Redesigned clamps
The needle-nose clamps fit battery terminals of any shape and size, with detachable integrated eyelets for permanent mounting. They offer improved clamping range, clamping force and higher conductivity compared to previous generations.

About the NOCO GENIUS2X4
From our tech experts at CEN
The NOCO GENIUS2X4 is a four-bank smart charger, maintainer and desulfator delivering 2A to each of four batteries, 8A in total. Each bank works independently, so you can mix 6V and 12V lead-acid and lithium batteries at the same time. It charges up to 40Ah per bank and maintains any size.
Who it suits
Collectors, bike owners and anyone with a garage full of vehicles that stand for long spells. If you only need to look after two batteries, the GENIUS2X2 is the smaller option.
Our tech experts advise
Four sets of clamps with integrated eyelets and four 10ft extension cords are included, so one central charger can reach several vehicles. A UK Type G power cable comes in the box. It measures 145 x 238 x 58mm and weighs 1.77kg. It is rated IP60, so mount it somewhere dry.
