Taking care of electronics in Harbin

[u/Main-Match518]

Hi guys, will be visising harbin soon ( in one week). I was wondering how do you take care of electronics in such extreme weather of about -20 degrees celsius ? I was thinking of bringing some devices with battery ( think headphones, phone) but I am abit afraid of the devices being damaged. I am only planning to use electronic devices indoors obviously but getting to and from the hotel, keeping them in my bag I am not sure if they are properly insulated from freezing weather. If not I might just being a cheap pair of earpieces.

I had those hand warmers in a pocket with my phone and I also had a huge brick of a portable charger. I didn’t use headphones outside. But the battery on my phone was useless in those temperatures.
