Purchased multiple cables. Unstable charging between external battery to cell phone. Same applies from power outlet to cell phone. Used two different cables same problems.
Does charge eventually. I get better performance/reliability from discontinued products (Griffin Brand) sold at Ross (discount clothing stores).
Adequate performance for price. But I purchased cables from Ross and will not purchase these Staples cables again.
It is working fine, and was relatively inexpensive. However, the real test of such a connector is how long it lasts before failure. Thirty days or less since purchase is not long enough to give a ranking higher than 3-stars.
