17 Watt Power Adapter Charger

CAUTION: The 17 watt charger/power adapter is rated as the fastest common way to charge an iPhone. The problem is that it is NOT compatible with all the lightning to USB cables you own (or the new ones I just bought). You will have to buy a new Lightning to USB "C" cable for $15 or more. The "C" stands for "Can't Use with Your Old Cable" grrrrr. This is not really very obvious when looking on line at the 17 Watt Power Adapter.
