Here is the Anker charge block I use. Great for travel. Just pull the plug and leave all the cords in. I have a bag that I just wind it all up into that goes in my backpack. In Europe I just need to use 1 European adapter to take care of all my devices. Bonus: It has a USB-C slot for the new iPads. If you don’t need that you can get the lesser option with no USB-C. I like that it doesn’t plug into the wall and uses a fairly long cord. That often helps.
