In many overseas hotels you need to provide your own HAIR DRYER, CLOTHES IRON, KETTLE, or WATER BOILER. To be able to make your own cup of tea, your way with your tea bag is a God send, after a long day exploring. Also who can trust a hotel iron not to ruin your best and only outfit! Finally, you can be a bedrangled mess if your room doesn’t have a hairdryer!
Recommendation: Go Travel Mobile Power Bank is your protection from a flat mobile or Ipad. Especially when some airlines are now refusing entry to laptops that cannot be turned on!
