The first result for "Raspberry PI Power Supply" on Amazon for me, is this: https://www.amazon.com/NorthPada-Tinker-Supply-Charger-Adapt... I get similar results with other searches for adapters and power supplies.
It's a fake UL mark. The manufacturer isn't listed in UL's database, and a genuine UL mark would almost always have the UL listing number right below it.
There's also lots of adapters there with no UL or Intertek marks or testing.
