Kiara Sky cordless curing lamp and battery pack with charger. The cord can be used for the lamp or to charge the extra battery. The extra battery and charger is perfect to free up space on your desk. Keep your lamp running with the cordless technology. 2 USB ports on the battery charger. Perfect for DIY or professionals. The lamp has been lightly used and is in perfect condition. There is nothing wrong with the curing lamp or batteries, I just switched to another brand.
