Multi-voltage. Multi-chemistry. Multi-battery type.
The GENIUS2X2 charges 6V and 12V lead-acid and lithium-ion batteries across multiple chemistries — flooded, gel, maintenance-free and AGM — and multiple battery types including starter, deep-cycle, marine and powersport.
Powerful, efficient and compact
High-frequency switch-mode technology converts AC power into safe DC power efficiently. An onboard microcomputer precisely controls the charging process to minimise power loss, keeping the unit compact despite its output capability.
The start-voltage sensor detects and charges batteries as low as 1V. For batteries below 1V, force mode can be activated manually to charge batteries down to 0V.
Redesigned clamps
The needle-nose clamp profile suits smaller terminal applications. Detachable integrated eyelets allow permanent mounting directly to the battery. The clamps are designed to fit terminals of any shape and size, with improved clamping range, clamping force and higher conductivity.

About the NOCO GENIUS2X2
From our tech experts at CEN
The NOCO GENIUS2X2 is a two-bank smart charger, maintainer and desulfator delivering 2A to each of two batteries, 4A in total. Each bank handles 6V or 12V lead-acid and lithium batteries, charging up to 40Ah and maintaining any size, and it recovers batteries from as low as 1V.
Who it suits
Anyone keeping two vehicles topped up from one socket, such as a car and a motorcycle, or a twin-battery boat. For a single battery the GENIUS2 does the same job per bank, and for four batteries there is the GENIUS2X4.
Our tech experts advise
Two sets of clamps with integrated eyelets and two 10ft extension cords are included, which helps when the vehicles are parked apart. A UK Type G power cable comes in the box. It is rated IP60, so mount it somewhere dry rather than in an open boat or engine bay.
