Sharper Image UV sanitizer and phone charger. Unit operates using a 5-Volt USB wall adapter or any USB power source (adapter included). It appears to use MicroUSB according to a response in the Q&A section. Regular price is $19.99 currently 60% off at $7.99.
My local Home Depot had over 100 of these in stock, so depending on your zip code availability may vary (e.g. YMMV)
