Some people experience a little bit of confusion with the charger used for the PixelWhip Rev2 & 3:
You need to plug the charger into the wall first and see the LED that indicates power, then put the battery in and see the LED of the battery charger change to red/orange, to indicate it is charging the battery. Disregard the green LED that shows up on the charger when it isn't plugged into the wall.
Charging problems with the PixelWhip Rev4:
The Rev4 now includes a USB charger and micro USB cable, unlike previous PixelWhips.
Please contact customer service at Support@BuyFiberFlies.com if you are having any issues with your charging system.
The attached photos are of the manual that comes with the PixelWhip Rev4. It explains how to insert the battery into the handle of your PixelWhip. Each PixelWhip should come with a user's manual, a modes manual, an 18650 battery, charger, and cable.
