How do I charge my heated pillow, and how long does it stay warm?Updated an hour ago

To charge it, first switch the heating off. Then connect a USB-C cable to the port on the controller and plug the other end into a USB charger. A flashing red light means it's charging, and flashing yellow means it's full. A full charge takes about 4 to 6 hours. Please don't use the heating while it's charging. 

The USB-C cable and wall adapter to charge the power bank are not included in the box, so you'll need your own. 

On a full charge, you'll get about 2 hours of heat on high, 3 hours on medium or 4 hours on low. That's the total time, not one go. The pillow also switches itself off after 1 hour each time you turn it on, and you can simply switch it on again.
