With the WHOOP Wireless PowerPack, you can charge your WHOOP anywhere. You can leave your WHOOP on your wrist, because you can easily slide this small wireless battery over the sensor. This way, the health and fitness tracker keeps measuring everything, and you can be sure all insights stay accurate. A full battery charges your WHOOP battery 1 full time. This way, your WHOOP One, Peak, or Life lasts for at least 14 more days. The WHOOP Wireless PowerPack is water-resistant, so you can also wear it while you work out outside in the rain or while you¿re in the shower. You can charge this small power bank in 2 hours with the included USB-C cable. The battery is small, so you can easily put it in your pocket. It doesn¿t include a charger for a wall socket. Use your current USB-C charger or buy 1 separately.
