About the Charger
Advanced Charging Control
Engineered with intelligent microcomputer supervision, this charger monitors each battery in real time. The constant-current pulse charging profile is optimized specifically for NiMH and NiCD chemistries, ensuring accurate, efficient, and safe charging every time.
Three independent stop-charging safeguards prevent overcharging and extend battery life — perfect for hobbyists who rely on consistent power.
Versatile & User-Friendly
Charge 1 to 4 AA or AAA batteries at the same time.
Each slot charges independently, so mixed batteries aren’t an issue.
A micro-USB input makes it easy to use wall adapters, power banks, computer ports — anything you’ve got.
Every slot features its own red/green LED indicator, giving you instant status at a glance.
