A pool party, a park day, a golf outing, a hang on the back patio — it’s all better with music! The Nano weighs only 3.5 ounces and supplies 5,000mAh of battery power — enough to keep me going to the end of the day. The winner, which I’ve been carrying every day for close to eight years now, is Magpul’s DAKA Essential Wallet. Just plug them into a USB-C source using the included wire whenever you need to juice them up. They’re an instant upgrade for any hot-swappable keyboard that takes Cherry MX-compatible switches, and I’ve been using them as my daily drivers for a while.
