About
Theo is the person friends text at 2am asking which power bank to buy. A former electronics engineer turned travel tech reviewer, he's dismantled more gadgets than he'd like to admit and has strong opinions about USB-C. He tests every product in real conditions—from humid jungles in Costa Rica to freezing trains in Norway—because specs on paper don't mean much if your charger dies when you need it most.
