Make sure your Pocket Charger is switched ON*. Plug it into a power outlet** for at least 20 minutes. We recommend a full recharge, which requires 2 hours. *Press the Pocket Charger’s button once and see if the lights turn on. If not, press and hold the button again, for 4 seconds. **Laptop USB ports may not have enough power to charge your Pocket Charger if it is completely discharged.
