Gotta keep the lights on, right? Well, for long road-trips or flights, you may find yourself needing some extra juice. We’d recommend having a small, power-dense USB charger with you, also known as a power-bank. Look for one that has at least 10,000mAh of power, which should get you two full charges on your switch. You want something sleek and pocket-sized, and that shows you exactly how charged it is, too.
