## Overview

The NOCO GENIUS2X4 is a premium 8A smart battery charger with four independent 2A banks, designed for 6V and 12V lead-acid and lithium batteries. Featuring temperature compensation, overcharge protection, and a desulfation pulse mode, it simultaneously charges and maintains multiple batteries safely and efficiently. Ideal for professionals and enthusiasts managing diverse vehicle fleets, it revives dead batteries and ensures optimal battery health with minimal effort.

## Description

This smart charger simultaneously charges up to 4 batteries, automatically adjusting voltage and current to optimize performance and prevent overcharging.

Review: Brilliant piece of kit. - Great piece of kit, use it to connect my vehicles in the garage using the quick connectors (have upgraded two to accept the GBX jump pack). Leave all of them to trickle charge and maintain battery life. LED display makes it easy to see when all batteries are optimised and wall mount keeps it tidy and out of the way. Would highly recommend.
Review: Not cheap, but worth every penny. - Mounted it in my garage, just perfect for keeping my various batteries in perfect condition over the cold winter months. Once I printed out the user manual i found it was intuitive to use, tons of accessories available to suit your needs. So much nicer to just hook up the 4 batteries and just leave it, not having to go out and switch a single charger between batteries every few days. But the thing I love most, it can charge a 6v battery, so perfect to put my friends classic motorbike battery on for some TLC that Noco chargers provide. Thus far, a godsend for me.
