In winter, the temperature is below zero, so the ipad air2 can't be charged (charged for half an hour, it can't be charged at all). Is it a machine problem or is it too cold?

Apple brand technicians said that Apple equipment has a temperature protection setting inside, and the normal use range is generally 0~35℃. Too low or too high will alarm or even automatically turn off the power. It is recommended not to charge when the ambient temperature is too low or the mobile phone is hot, otherwise it will affect the battery life. The temperature is low, so the Apple brand heating wire can't work. Apple heating wire will only work at 25.0000 1 000 1℃, otherwise it will not be heated.
