What Loads Can Be Connected to the Tapo/Kasa Plug

The Tapo/Kasa smart plug is designed primarily for resistive loads, such as heaters, kettles, and electric irons.

However, it is not suitable for high-power inductive loads driven by motors, such as air conditioners, refrigerators, or washing machines. These devices typically generate a high inrush current during startup, which may exceed the plug’s rated current, risking device damage and voiding the warranty.

Before using a motor-driven appliance with the plug, we recommend checking the device's horsepower (HP) rating to ensure it does not exceed the plug's supported load capacity.

You can check the maximum load supported by your Tapo/Kasa plug by visiting the TP-Link official website, clicking the Search icon, entering your device model, and opening the Specifications page. To check the supported load types, you can also refer to the product’s Quick Installation Guide under the Support page. Please note that available documents and hardware versions may vary by region. If you still cannot find the information, please contact TP-Link technical support.

Supported Load Types

Using Tapo P100 (EU) as an example, the plug supports the following load types:

Usage Guidelines & Precautions:

1. For your safety and stable operation, it’s not recommended to run the plug at full load for extended periods. If you will be using the plug for continuous long-term operation, please keep the total connected load at 80% or less of the maximum rated power.
2. If you have connected a power strip or extension socket to the plug, please make sure the combined rated power of all devices plugged into the power strip/extension socket does not exceed the plug’s maximum rated power. For loads requiring long-term operation, please also follow the guidelines above.
3. Avoid placing your plug in areas exposed to direct sunlight, high temperatures, or enclosed spaces.
4. Avoid placing heavy objects on the plug housing.
5. If your smart plug feels warm during use, please refer to these troubleshooting steps.

Unsupported Load Types

Using Tapo P100 (EU) as an example, the following loads or usage scenarios are not supported or not recommended:

• Overrated or high-inductive loads: Loads exceeding 10A or 2300W, as well as inductive loads over 1HP, are not supported.
• Devices with excessive startup or surge current: Devices with high startup/inrush current are not recommended. This includes certain 60–75W power adapters/USB chargers without PFC (Power Factor Correction), which may generate excessive inrush current when the relay switches on, potentially damaging the plug.
• EV chargers: EV charging is not supported because the charging current may exceed the plug’s rated limit. Under normal conditions, an EV charger with a power factor close to 1 draws about 10A at 230V / 2300W. If its internal PFC circuit is abnormal, the charger may still function, but the actual current can rise significantly. For example, if the power factor drops to 0.7, the current at 2300W may increase to about 14A, exceeding the plug’s 10A rating.
• Safety-critical or unsuitable applications: Devices requiring uninterrupted power, devices used outside the product’s specified operating conditions, and power strips are not recommended, as they may create safety risks or cause the total load or surge current to exceed the plug’s design limits.
