The provided cable has one end (USB-C) that fits into the speaker, and the other end (USB-A) fits into any computer USB port, or USB-A out charging port—you surely already have one on some device or other that you own. We highly recommend a multi-USB-out charger like the universal travel chargers we review that works in any country, has an internal protective fuse, and charges multiple devices simultaneously. It's great whether you're travelling or staying put. Charging of the Tribit Stormbox Micro takes about 3.5 hours.
