    I bought this for travel to India. It passed in carry on luggage. Beware not to pack in check-in luggage, as it is not allowed. The pack is pretty heavy but light enough to pack in backpack. It charges my Samsung Galaxy S20 and son's Galaxy S22 as a fast speed, not superfast speed, but that is acceptable to me. Ensure you have the right cable. It would not charge my tablet (micro-usb) with certain cables. Could not get the trickle charging to work.
