MiBoxer C4 Smart Battery Charger: Review & Test

Gearbest link: http://bit.ly/2qekGqd (Coupon code: MiBOXER) An in depth look at the new intelligent battery charger from Miboxer. This new model offers charging at up to 800mA for Li-ion cells as well as a testing function on slot 4 for capacity and battery internal resistance. How does the C4 hold up against other chargers? I compare it to the Nitecore D4 one of the most popular chargers on the market.
