Introduction

Like any other electrical appliance, the smart plug emits heat during operation. It would feel warm or maybe a little hot after working for a while, depending on the environment. This article explains why your smart plug may feel warm and outlines steps to check its condition and ensure safe operation.

Troubleshooting

Step 1. Put your smart plug in an open area, do not cover it with objects, and avoid placing it in a closed space to prevent overheating. Avoid using the smart plug in humid or damp environments, as moisture may compromise electrical contact and cause overheating.

Step 2. Poor contact between the plug and the outlet may also cause heat buildup. Please check for any debris, dust, oxidation, or corrosion on the plug or inside the outlet.

Step 3. Keep your smart plug away from direct heat or excessive sunlight.

Step 4. It is not allowed to plug any electrical appliance whose power exceeds the smart plug's maximum load; otherwise, it could cause a safety issue or even a conflagration.

Common high-power appliances that generally should be used with caution include space heaters, hair dryers, toasters, kettles, and irons. For safety reasons, the load should not exceed 80% of the rated maximum capacity.
Please also note that some inductive loads can draw a significantly higher inrush (peak) current at startup, which may damage the smart plug even if the device’s rated power appears to be within the supported limit. Typical inductive appliances include air conditioners, refrigerators, washing machines, fans, water pumps, and vacuum cleaners.

Step 5. If the smart plug is too hot to touch or smells burnt, please stop using it immediately, and please contact our support team with the following information for further assistance.
