You’ll need to charge the Polaroid Lab before use. Plug the USB charging cable into a phone adapter (5v, 1A) or your computer’s USB slot, and the micro-USB end into the back panel of the Polaroid Lab.
Charging LEDs will turn off when the Lab is fully charged. A full charge takes about 2 hours using a wall socket and phone adapter, or up to 4 hours using a computer’s USB slot. A fully-charged Polaroid Lab will have enough power to shoot 100 packs of film, depending on usage. Remember to turn off the Polaroid Lab after use to conserve battery.
