Myeongdong has two Daiso stores: Main Store (43 Myeongdong-gil) and Myeongdong

Station Store (134-1 Toegye-ro), both 10 AM–10 PM, with digital accessories grouped together. If your charger has an older USB-A port, get the A to C 1.5m (₩2,000, 7,616 orders). Korean outlets take two round pins, so bring a plug adapter too.
