The NOCO Genius 2X2 is a compact two-bank smart charger and maintainer for 6-volt and 12-volt batteries. Each bank delivers 2 amps, for 4 amps in total, and it handles flooded, gel, AGM and maintenance-free lead-acid batteries as well as lithium-ion. An integrated thermal sensor adjusts the charge to ambient temperature, and it can revive batteries down to 1 volt, or from zero volts using force mode. It also detects sulfation and acid stratification. It measures 4.4 x 5.1 x 1.9 inches and weighs 1.1 lbs, with a 40Ah capacity range.

Our take

Two separate 2A banks mean you can keep a starting battery and a small auxiliary battery topped up from one unit. The 40Ah capacity range keeps it to small batteries, so large house banks need a bigger charger.

From our buying guide

NMMA says charging sources must meet the charging profile the battery maker recommends. A charger's presets are its own maker's, not the battery's, so set it from the battery maker's figures.

Check before you buy:

  • It can follow your battery's profile, since not every charger can follow a lithium maker's.
  • Its output suits your bank. ProMariner recommends about 10 percent of the batteries' total amp-hour capacity, with one charger output for each battery.
  • It suits how you'll use it, since ProMariner says its waterproof chargers are for batteries not in use while charging.
