    Quality product
    I've used it to charge 4 Li-Ion 18650 bateries recycled from a laptop battery. Also supports Ni-MH, NiCd, Po-Li etc... So far so good. Device feels robust, display has lot of info. Also has a mode that tries to recover damaged batteries.

    As a con, you need an external 5V power supply since it only has a micro USB port to get the power, despite it can also be a pro because you can use any old phone charger to power the unit.

    Overall I'm very happy with it.
