Review on 🔌 Universal Travel Adapter with Dual USB Ports - All in One AC Wall Charger Plug for Cell Phone Laptop - Universal Compatibility for USA EU UK AUS by Melanie Lujan

Good universal adapter. I've only tried US plugs in European outlets, but they worked as expected except for one. In Denmark, almost all the sockets I saw were built a bit into the wall, and this adapter didn't stay in the duct, often fell out. In the picture you can see the setup I set up to charge without the adapter falling out and what the internal jacks looked like. Maybe it would be good if the adapter had a lower part, but for a European it only has two upper ones.
