Product Description
Got two batteries and only one charger? If you're constantly shuffling a single charger between your car, boat, or RV — or worse, letting one battery sit dead while you charge the other — the GENIUS2X2 solves that problem for good.
This compact charger has two independent 2-amp banks, so you can charge or maintain two 6V or 12V batteries at the same time, side by side. No waiting, no swapping cables, no guessing which battery needs attention first.
Safe to Leave Plugged In — Always
The GENIUS2X2 is fully automatic. It monitors each battery, delivers exactly the charge it needs, and switches to maintenance mode once it's full. That means you can plug it in before winter and forget about it until spring, with zero risk of overcharging.
Brings Weak Batteries Back to Life
A battery that won't hold a charge isn't always dead — it may just be sulfated. The GENIUS2X2 detects this automatically and runs a repair cycle to help reverse the damage, often restoring performance and extending the battery's life. It can even detect and safely charge batteries as low as 1 volt, with a manual Force Mode for batteries all the way down to 0 volts.
Built for Any Battery, Any Vehicle
Whether you're maintaining:
- A car, truck, or SUV battery
- A boat, RV, or trailer battery
- A motorcycle, ATV, or lawn tractor battery
- An AGM, gel, flooded, or lithium (LiFePO4) battery
...the GENIUS2X2 handles it. It also adjusts for outdoor temperature swings, so it charges accurately whether it's a hot garage or a cold barn.
Small Charger, Big Convenience
At just over a pound and small enough to tuck on a shelf, the GENIUS2X2 punches well above its size. Redesigned clamps grip terminals of any shape, and each bank includes its own set of accessories, so you can mount one charger in two different spots if needed.
Stop babysitting your batteries. Grab the GENIUS2X2 and keep everything charged, healthy, and ready to go — all winter, all year.
Frequently Asked Questions
Can the GENIUS2X2 charge two different types of batteries at once?
A: Yes. Each bank operates independently, so you can charge a 12V AGM battery on one side and a 6V lithium battery on the other at the same time.
Will this charger overcharge my battery if I leave it connected too long?
A: No. The GENIUS2X2 is fully automatic and switches to a low-power maintenance mode once the battery is full, so it's safe to leave connected for weeks or months.
How do I know which charge mode to select for my battery?
A: Select the voltage (6V or 12V) and chemistry (standard, AGM, or lithium) that matches your battery. The charger handles the rest automatically, including temperature adjustments.
What size batteries can the GENIUS2X2 handle?
A: It's rated for batteries up to 40 amp-hours per bank, making it a great fit for car, motorcycle, marine, RV, and lawn equipment batteries.
Can this charger revive a completely dead battery?
A: In most cases, yes. It can detect and charge batteries as low as 1 volt automatically, and its manual Force Mode can jump-start charging on batteries as low as 0 volts.
