I have always forgotten the battery-charging adapter of my electronic devices during travel, so now consider purchasing the adapter.
However, I wonder if a universal worldwide adapter is safe enough to use in a general household. In a general household being a room either booked via Airbnb or rented for a short-time period.
Specifically, I'm more concerned that using the adapter may break my devices or the outlet of the room, or worst of all, ignition, than a chance that it breaks the adapter itself.
Note that I use it for 360 days out of 365 days as I travel for all year round. I believe these products are designed for a short-time trip, and that's why I'm worried.
So how safe is it to be used in a general household?
Is it more likely to cause those sorts of troubles than an one-to-one adapter (or no adapter), given that it is used all year round?
