Hiking the Arctic Highlands with a solar powered mobile

The Arctic Char is one of Norway’s most appreciated fish. Not only is it very tasty, but it’s also well known for putting up an epic struggle. It’s this combination of attributes, which made Esa Karpoff, one of our Lokki solar powered phone testers take his son, Mihkkal, on a 50km trek into the Norwegian arctic. Hiking through one of the most deserted place on earth, he’s also made sure he took his solar phone with him.

Hiking to the end of the world

I didn’t expect Lokki to charge very much at all during the trip, as the weather was rainy and cloudy, so I charged it before leaving. I didn’t pack my big camera. Even after all my years spent trekking, the backpack was already heavy enough at 30kg.



For the trip Esa put Lokki in a protective bag on the top of his backpack. This was the best day for solar energy harvesting. It helped top up the battery that had been charged two days before. 30mAh would be good 18 minutes talk or for 15 extra hours of stand by time.

Hooked on fishing

Fishing can be a dangerous business and today I hooked not only Arctic Char, but my finger! Nothing serious but it makes you realize how important it is to have mobile phone when travelling these “dangerous waters”.


The sliding stopper Esa created for his back pack really highlights the ingenuity you need to survive in the wilderness. The design is outstanding!

Yet despite this, the cloudy weather didn’t provide much opportunity for much solar harvesting. 3mAh is hardly good for 2 minutes talk or 1 hour stand by.

A warm welcome home

Diary: 06.08.11

After four days of mountains and rivers, my son and I made it back from Norway. It was drizzly and windy practically all the time, but the most important thing was we got some fish! At around noon we got back to the car. It was nice to be warm again. During the night in the wilderness the temperature dropped below 5 degrees. Summer in Lapland disappears in the blink of an eye.


Even though the first day’s harvest was relatively good, 30mAh, it was still just one quarter of what Lokki can harvest in the best scenarios. Because of the cloud and drizzling rainy, the other three days harvest was only 3 to 4 mAh per day.  Nonetheless, just this small amount of harvested daily solar energy would be enough to make a brief call every day, even if Esa started with an empty battery.

Esa may have caught more fish than he did sun’s rays, but Lokki has still proven its worth in tough conditions. Have any questions about Esa’s adventure? Let us know in the comments below.
