Use the Travel Adapter
The travel adapter rapidly charges your phone from any 120/220 VAC
outlet.
1. Plug the large end of the Travel Adapter into a standard 120
VAC or 220 VAC wall outlet.
Important!: For connection to an electrical supply not located in North America,
you must use an adaptor of the proper configuration for the power
outlet. Use of the wrong adapter could damage your phone and void
your warranty.
