Review on KNACRO Balance Battery Charger Discharger by Chris Long

I bought three of these for a project with 18650 cells In less than a month, two out of three showed poor mAh charge and discharge values, as I also noticed that the value of total charge was lower than what I could measure with a voltmeter. I have four of these chargers in total and like their construction, but suspect quality assurance in the manufacturing process is producing an unreliable product. I would not recommend buying them for critical project needs.
