How do I charge my Joan device?

Joan is powered by a high-performance rechargeable 5400mAh Lithium­-Polymer battery that needs recharging once every couple of weeks. You can either use the enclosed Micro-USB cable or use a certified Micro-USB charger with an output rating of 5 V, 1A max. The power must be supplied from an external power supply source that complies with the requirements for Limited power source. The charging time will depend on the power supply and varies with use. Charging a single device on 1A of current requires approximately 6 hours. Please note that if charging more than one device on a USB hub simultaneously, the distributed current of each device drops, which extends the devices' charging time. Using your laptop or PC for charging could mean that your devices might not charge fully when charged overnight. You can double check battery levels at any time by logging into the Joan Portal and checking the device battery status.
