SunPouch on Kili (Kili 3)
'Fun in the African sun' is a motto Harald Schulz, Suntoy's Technical and Managing Director, embraces whole heartedly – especially while hiking Mt. Kilimanjaro with Tribe Safari
. A playful barter system began when fellow hikers' smartphones needed top ups. Would Mr Sunshine, aka Harald, mind charging their smartphones with his SunPouch? No problem. Barter value: a steaming hot cup of Tanzanian plunger coffee!
Harald managed to send long text messages, multiple photos and even videos. The extra solar power in his smartphone worked magically. Sealing the solar battery with insulation tape did the trick. "It is coming down in buckets. Temperature is around five degrees. The solar harvest from the SunPouch, considering the adverse weather conditions, charged a smartphone from empty to over 50%. Our SunPouch prototype has a battery that can bridge two days of no sun so it's performing well. It is powering my smartphone and providing enough light to comfortably navigate around my tent."
With the SunPouch strapped onto his backpack, charging while on-the-move, Harald hiked to an altitude of 4 700 amsl. "The walk was beautiful culminating at the lava towers. Altitude sickness and headaches have thankfully avoided me. It must be my cigarette smoking. I am sitting in my tent, in my snug down jacket, eating chocolate. Life is good!"
