Great UV/LED lamp and bonus charging ports [SEP] Diving into doing my own manicures at home meant that I needed the proper lamp for curing gel polishes. After much searching I found the Mercase 72w LED/UV lamp with its additional usb and usb c charging ports. These additional charging ports are a complete bonus but make total sense. I can plug my e-file into the USB port and run the file with no problems. Port also charges my iPhone 7 just fine though the usb c port did have some issues with slow charging on my husbands S9. I love the smart “on/off” feature that it has and now my manicures take half the time since upgrading from a small 6w travel lamp. With the polish system that I am using, base coat cures in 30s, polish layers ( single layer) cures in 30s and top coat cures in 60s and being able to put my whole hand in with plenty of wiggle room is the best. The only thing that caught me off guard was that the husband saw the power supply and per the specs on the power supply, the lamp is only putting out 48watts, so a little odd that would be labeled 72watts if it’s only 48.
