Personally, as an engineer, I would only use a smart plug for a freezer or refrigerator if it was specifically designed for heavy duty appliances. The reason is that these devices have compressors which cycle on and off (you can typically hear them powering up), and when they start a new cycle there can be a really big power surge, which will then knock a regular smart plug off power as it tries to avoid the power spike.
The Tapo 110 product description at amazon uk, for example, specifically says:
- Avoid plugging in appliances with a motor/compressor higher than 1/6HP, such as an air conditioner, You can check the motor/compressor rating on your appliances or consult their support
Most uk freezers will be higher than 1/6 HP. And even if it was exactly at 1/6 HP, I personally wouldn’t run it on a regular 13 app smart plug as the very frequent hitting of that mark is likely going beyond what a regular plug is designed to support.
