D-MASTERY Wireless Charging Digital Alarm Clock with LED Display - Alarm Clock Purchased from Amazon. No operational issues. Wireless charging also works without problems. I'm selling it because I couldn't find a place to put it and I often use other clocks. The LED display lights up even in a dark room, making it easy to see and beautiful. There is some rippling on the back (see photo 6). I think you can use it without worrying too much during normal use. No box or instruction manual. Included items are the main unit and a USB-powered power cable only. ■ Qi charging compatible - Charge by simply placing the device ■ USB power supply ■ LED display ■ Alarm function 【The following is a reference from the EC site】 Digital clock, stylish, interior, alarm clock, slim, simple, multi-functional, alarm clock, loud volume, LED, Qi wireless charging, smartphone, compatible with iPhone 8 and above, desktop clock, USB power supply, space-saving Brand: D-MASTERY 【Qi International Certification・Wireless Charging Function】 This alarm clock can charge Qi-compatible devices and mobile phones simply by placing them on top of the main unit.
