Depends on your device battery size and power source used but the charge rate is 15%-25% per hour in my test of a Note II, Galaxy S4 and Galaxy S5.  A dead battery should charge to full in 3-6 hours.  (different amperage power sources can make these results vary up or down)  I've been doing this a long time and can tell you most generic cables on eBay take 8-12 hours or more to complete a charge.

Compatible with:
  • Any Android smartphone
  • Most Android tablets
  • The entire line of Kindle tablets dating back to introduction in 2007
  • If you have specific compatibility questions let me know

PLEASE NOTE:  "Rapid" charge is a subjective term.  In this listing the term "rapid" is stated in relation to other generic cables for sale on eBay.  I am not guaranteeing a specific amperage or charging speed.

PLEASE NOTE:  Galaxy S5 and Note III owners - your phone uses Micro USB 3.0 technology (which is backwards compatible with the standard micro usb in this listing).  When you plug these cords in a portion of the charging port on your phone will not be used.  This is normal and the cord will still charge the phone normally.
