Please Note

In March 2017, the governments of the United States and the United Kindom issued orders restricting a variety of different electronics from carry-on baggage when traveling to the USA and UK. The ban is likely to result in difficulties carrying portable chargers from major airports in Africa and the Middle East (with more airports expecting restrictions soon). Therefore, we strongly recommend that you confirm with your airline or airport before traveling with portable chargers to ensure problem-free flying.
