## Description

## NOCO GENIUS2X4: 4-bank charger 8A (6/12V)

With the NOCO GENIUS2X4 you charge and maintain up to four batteries at once from one mains socket: a motorbike collection, a small fleet of mowers or a workshop maintenance corner. Each output supplies 2 A and is intended for batteries up to 40 Ah.
If two outputs are enough, the GENIUS2X2 is more compact (0.5 kg versus 1.77 kg). If what you need is more current per battery, neither fits: a GENIUS5 gives 5 A to a single battery of up to 120 Ah.
It covers 6V and 12V, with AGM and Lithium modes.

### Features

- •   Four independent 2 A outputs.
- •   120 W max., 30 W per bank.
- •   Up to 40 Ah on each bank.

- •   Starts from 1 V of battery voltage.
- •   Temperature compensation between -20 °C and +40 °C.
- •   3 m extension cables supplied.
