They work very well

Quick charging

Always fully charged your batteries with these chargers.

Works great.

Charges well. I use it on a 18Ah, charges through the night. I wished there was a 4-5A charger to help it go a little faster for the 18Ah and up to the 23Ah

Great charger

simple and did the job good

Great product

So I haven’t use it yet cause the battery i ordered 12v 23ah came fully charged and used it 5 or 6 times at 10 plus hours a day fishing and still have a full battery ? its crazy how the battery holds a full charge maybe next week I’ll use the charger lol
I’m running a humminbird helix 7 fish finder and a marcum underwater camera also.
