Essential for Overseas Travel: ASUS Smartphone USB Charger for C-Type Outlets - Overseas Charger ASUS Overseas AC Adapter Charger PA-1050-39 This is a USB charger specifically for C-type outlets, which came with an ASUS smartphone I purchased in Thailand 9 years ago. It supports 200V and 220V overseas, with an output of 1A. I haven't used it since returning home because the outlet shape is different, and I've only used it a few times. Since the outlet shape is a C-type outlet (for overseas use), you can use it directly in outlets at airports, cafes, hotels, etc., without needing an adapter. Adapters are surprisingly expensive and bulky, so a dedicated charger is more convenient. Since it's made by ASUS, you can use it with confidence. For those preparing for overseas travel, how about it? You can search for "(destination) and outlet" to find out the outlet type in your travel destination. Shipping is free, and I will ship via "Yu-Packet Post Mini" or "Nekopos." Please understand that I will use recycled materials for packaging. Voltage... ~5V
