Great app for testing USB charging

Ever wonder why it’s taking so long for your phone/tablet to charge?  I highly recommend “Ampere”.  I used it to test the quality of various chargers and USB cables.  The best cables enabled 1060mA, the worst, 460mA.  I wound up tossing the cables that did less than 860mA.  Ampere is a free download, or pay $1.13 for the Pro version.
