Bought the Ugreen USB-C to USB-A Adapter from Lazada during their 8/8 sale for S$3.99 with free shipping to Singapore. Their usual retail price is S$5.39.
This is a USB 3.1 Gen 1 On-The-Go (OTG) USB-C to USB-A adapter, and hence it supports any phones, tablets, and laptops with a USB-C port.
The theoretical data speed of USB 3.1 Gen 1 is 5 Gbps.
Ugreen is afraid most people will lose this gadget, and hence it comes with a keychain hole for you to attach the included strap.
Dimension and weight-wise, it is extremely portable, measuring 26 x 15 x 7 (mm) and weighing 4 g.
The outer case is made of an aluminum alloy case.
If you do not want the bulk of carrying a dongle that acts as an adapter to USB-A, this adapter is a good alternative.
