I'd I am not wrong the charger output is 750 mAh. The power bank output is higher. Check the output. Higher mAh output charges battery faster

Why not. as long your Phone doesn't. Get hit by lightning it's fine

I think all power bank available on market having output 5v and 1 amp
But Lumia 640 has 0.75 amp charger

Yeah, 4 hours isn't normal. 2 hours and some is the usual for me.

Check out u r charger rating it may be 1 amp or 2 amp.
But Lumia 640 having official charger having rating 0.75 amp.
