This is a USB Type micro-B power cable, approximately 1 meter long, with a Type-A connector. It can be used to charge smartphones, tablets, etc. A green LED lights up. Operation has been confirmed. Also, since it has a Type-A connector, you can charge Type-C devices if you have a separate Type-A to C cable. The exact output capacity is unknown because there are no specification stickers on the main unit, but I believe it was around 1A in total. (This is not a high-output type. Recommended for those who just want to be able to charge.) - Connector Type: USB cable plug: Micro USB Type-B USB connector: USB Type-A - Input: DC 12V - Cable length: Approximately 1m - Power supply: Car cigarette lighter socket (12V car) - Condition: Used Please consider this item with the understanding that it is a used product.
