Who am I

I´m Teemu Vidgren, a Finnish ultrarunner, Ironman triathlete and wannabe photographer who likes to travel alone in unexpected places. On my spare time, I drive digitalization and cloud at Microsoft.

Hopelessly addicted to long mountain runs, biking for hours on remote trails, and swimming in calm forest lakes before the sunrise.

  3. Hi Teemu,
    I came to your blog to read about your first ski trip on Kungsleden. I am wondering: how many batteries did you pack for your camera and how did you store them to keep them from draining due to the cold?
    Kind regards


    1. Hi Christian,

      having adequate battery power through the trip was one of my concerns as well. I ended up buying a handful of camera and drone batteries which are both relatively heavy and difficult to pack safely.

      My strategy was 1) packing all the electronics (incl. number of batteries) in one hard case, 2) wrap it with my warm spare clothes (down jacket or sleeping bag were perfect options) and 3) put a chemical toe warmer (like this https://www.amazon.com/Grabber-Toe-Hand-Warmers-Activated/dp/B003KYX32A) inside the case every morning. The warmer seemed to keep the electronics relatively warm through the day and batteries remained charged.

      If I was heading out now, I’d take less camera batteries and one big power bank instead. Currently traveling with this one https://www.goalzero.com/collections/adventure-power/products/new-sherpa-100ac-wireless-power-bank

      The camera I was using was in my pocket warmed by body heat.

      Hope this helps, have a safe trip!
