## Description

## NOCO GENIUS2X2: 2-bank charger 4A (6/12V)

The NOCO GENIUS2X2 is worth it if you keep two vehicles with small batteries, say two motorbikes or a bike and a ride-on mower, and want to maintain both from one unit. Each bank gives 2 A and handles batteries up to 40 Ah, at 6V or 12V.
With a single battery, the GENIUS2 does the same job with one output. With three or four, the GENIUS2X4 offers four identical banks.
The 3 m extension cables help you reach vehicles parked apart, and the unit can stay connected 24/7.
