[Q] usb cable , Qi charger & power bank , please advise me

i was recieved a car charger from ANKER , but without usb cable , i am wondering what is the suitable usb cable to use with car charger for my nexus 5 ...?

and i am looking for Qi Charger for my nexus 5 , what is the best one available now ...?

what about portable charger ( Power bank ) ,,, i am looking for one also since my cellphone is losing the battery very quickly ...??

i bought this car charger from Anker ("press here") , but i don't know what is the suitable Usb cable the i have to buy , is there any specs for this or any tricks i have to know it before i purchase any cable ..??


regarding the Qi charger , i need a product that will not cause any heat or over charging of the battery , since i used to put the cell phone in the charger at night and sometimes i forget to pull it out from the charger , i saw some posts indicating there are some Qi charger will stop charging automatically when the battery become full , that is will be awesome soon as the nexus 5 battery is not removable one .
and also i heard that most of the Qi charrger need to place the nexus 5 centered or in aligned position with the charger otherwise it will not work.

i have some links that put in my cart in Amazon :
Lerway Wireless Qi Power Charger Pad for Lumia920 HTC 8X S4 S3 Note II (Black)

my budget for the Qi is 20$ to 30$ ...
