Product Features
Note This unit is a battery charger. It needs to be connected to an external AC source, not a car jump starter
5A Battery Trickle Charger — Charge battery 5 times faster than Sigma 1. It outputs 12V DC 5A / 6V DC 1.8A. It's perfect for 15 to 121Ah batteries in 12V Mode and 6 to 50Ah in 6V Mode. It also works as a maintainer, desulfator, float and trickle charger all in one for lead-acid and LiFePO4 batteries

Clear LED Display — Bid farewell to unknown failures. The 3.2 - inch LED screen shows real - time battery status, voltage, charging mode, incorrect operations. And the LED icons make it visible in strong or dim light
Revive Depleted Batteries — Got a dead battery? Loading Mode can restore batteries as low as 0.3V, and Repair Mode can refresh those with over 2V. As a desulfator, it uses pulse charging to save you from buying a new battery

Customer Reviews
I also own a Noco Genius 5 charger that I thought was the bomb when it came to battery charging. Until it met the Costco interstate battery in a 2000 Subaru Forester. To be fair the Forester has a phantom leak that I have been too lazy to diagnose (it’s a 25 year old car, so not the daily driver), but the Noco could not maintain a charge on the battery when it was charged, and definitely not when it drained down (because the Noco shut off). I tried all the various settings to the Noco to get it recharged, but no luck.Reading the reviews on the Hulkman, I was skeptical but figured it was worth a try. At first the battery still wouldn’t charge, but after a few goes at the repair function, the Hulkman rescued the battery and still continues to keep it charged, unlike the Noco. Maybe it’s user error, but the Hulkman has me sold.I should also note that using it is much more intuitive than the Noco. Probably user error again, but I really don’t need to refer to the manual for the Hulkman.Highly recommended.
