Replacement fans for Opus charger. Replacement fans can significantly prolong the life of the Opus quality charger. Low price, well packaged, delivered quickly. Everything is alright. I recommend it.

Feature rich, multiple functions easy to use. the only issue - when my batteries are depleted to extreme low voltage it would not detect them, need to charge those with a dumb charger a bit.

Performs as expected. Tested on various battery types and no problem noticed.
It would be a nice improvement if it could also charge usb devices.

Отличное зарядное устройство заряжает все типы аккумуляторов
