Arlec Smart 2.1A USB Charger Plug
Model reference: PC389HA
Tuya-Convert might not be possible for this device if the manufacturer started using newest Tuya firmware since this template was published. Instead you can likely serial flash Tasmota without soldering with a flashing jig, if the device is easily opened.
Use Tuya Convert 2. This configuration will give you a Blue LED on the switch when on, nothing when off.
