International Travel Adapter

These should be included with the charger, or least be a inexpensive add on. If you are not in the US you are forced to the buy them. They are way to expensive for a bit plastic.

System works great

The travel adapters work super well, I keep mine on the charger permanently as I live outside the US. Note that doing so will prevent you from storing the charger, travel adapter and charging cable in the carry case but I simply remove the charging cable and the charger and travel adapter still fit well.
