Travel is testing enough without your devices running out of battery mid-journey. Handily, Horizn Studios’ ‘M5’ carry-on suitcase is fitted with a smart dock so you can keep your phone and tablet powered up on-the-go – at full capacity, it provides enough juice for up to six charges. It’s made from a combination of aerospace-grade polycarbonate, nylon and leather and fitted with four 360-degree aluminium wheels. Off on a long trip? Invest in the coordinating too.
