Phone on Fire, Kindle and a Kettle

It was with great excitement I unpacked my new BioLite camp stove today. It was ordered 5 minutes after reading about it in PopularScience+. 10 days later it was delivered on my door. For a camper this is good news - it´s a great camping stove (It boiled 1 litre of water in less than 10 minutes), and it has a USB outlet. As we all know - most modern phone batteries does not survive 2 days of tent life.
