YOU’VE JUST COOKED BREAKFAST TO PERFECTION on your camping stove. Clearly you need to take a photo and post it to Instagram before you can tuck in. Oh, no! Your phone is dead! But wait! The Tegology Tegstove is here to save the day. The Butane-powered device generates and stores electricity whenever it’s lit. Gadgets are charged via its USB port, so you’ll never run out of batteries on a camping trip again. Of course, it must also be able to cook and it does so incredibly well, with wide stove arms providing consistent heat and retractable tripod legs for stability (£125; tegology.com).
