  both I think?

  But it seems to only affect low voltage grid countries if I understand it correctly

    I read high voltage has it worse, because the ac adapter circuit has a lot more work to do, so it runs hotter.

      V * A = W

      The device operates at a certain wattage. If the voltage is lower, you need more amps to reach the same watt. Amps is what makes conductors hot.

      Example:

      200V * 1A = 200W

      100V * 2A = 200W

      To quote the link above that you didn’t read so I had to re-read to make sure I’m right:

      The issue stems from the difference in standardized voltages between regions, with the US running on 120 volts, compared to China’s 220 volts (where bambu is based). This requires almost twice the current for the same total power draw in the US compared to most other regions, contributing to higher temperatures being reached due to Ohm’s law.

      ---

      And about the ac adapter - it’s not the cause of the burning issues. And if they specc it for china’s 220V, it should work fine in most of europe.

        So it’s bambu fault for not thinking about those countries that want to do things differently from the rest of the world

        (Most of the world operate between 220-240v, the most notable exceptions are north america, the most north part of south america, Japan and i think israel)
