This UV Phone Sanitizer with Wireless Charging Pad uses UV-C light technology for sanitization to kill 99% of microorganisms tested. Two UV germicidal LEDs (270-280nm wavelength) are used for optimal sanitization. Press the button once for a short 90 second sanitization. Press the button twice for a 5-minute-deep clean sanitization. It can sanitize almost anything that fits inside (7.5" L * 4" W * 1" H) such as large phones (iPhone 12 Pro Max), keys, credit cards, watches, eyeglasses, jewelry, etc.. The sanitization will be stopped automatically once the lid is lifted to avoid UV light exposure. The wireless pad supports 5W wireless charging and works with most plastic phone cases.
