Charge your Actofit Super Fitness Band easily with the removable strap. Pull out the band from the side which has ‘OPEN’ written on the backside of the strap (because the other side doesn't have the metal chips which are used to charge the device). Insert the side with metal chips into your Laptop or USB Charger. Charge the bracelet for 45 minutes before using it. Only use 5v/1A USB port for charging. One full charge powers it up-to 6-7 days.
