Beats Pill

A long-haul travel speaker that doubles as a phone charger. The Pill runs up to 24 rated hours, and the included USB-C cable lets it top up your phone at a campsite with no outlet, so one battery covers both music and navigation. It is IP67 sealed, weighs 24 ounces and carries on a removable lanyard, with a grippy silicone back that keeps it from sliding off a sloped picnic table. Ten minutes of charging gives about 2 hours of play. It is a natural pick for iPhone owners, though it works with any Bluetooth phone.
