The I-1 will not be charged upon purchase - it must be fully charged before first use.
Due to the high power requirements of the ring flash, we recommend that you always charge the I-1 before use, as we recommend to always use the flash for every shot, unless you’re shooting in bright, direct sunlight. You should charge the I-1 fully before every use to ensure it has enough power for the duration of your shoot. A full charge usually takes just an hour if you use a smartphone charger, or up to 3-4 hours when you use a computer.
To charge the camera, plug the USB charging cable into the micro USB slot on the camera door, with the yellow dot on the cable facing up. Then plug the other end of the cable into a charger such as your iPhone charger, or into your computer’s USB slot. The red power indicator LED will switch off as soon as the battery is fully charged.
