TP-Link Kasa KP303

TP-Link Kasa HS300 and KP303 have a similar compact design, except that the HS300 model is larger in length due to the greater number of outlets it provides. Both are also made of flame-retardant material that ensures safety and durability.

Outlets of both smart power strips are each equipped with a control button to turn on and off the corresponding outlet manually, and an LED indicator that lights up when the corresponding outlet is on. Both power strips also have a SYS WiFi LED that shows the status of the WiFi connection, and a Protected LED that lights up when it is under surge protection.

Despite the similarities, TP-Link Kasa HS300 as the more expensive model has additional design features. These include a Grounded LED that lights up when the smart power strip is properly grounded, and an Overcurrent Protection Switch that allows for manual turning on and off of the entire power strip. This switch is particularly helpful as it allows you to manually restore power in case the HS300 turns off automatically when it's overloaded with electricity, preventing any potential electrical hazards.

#4 Features

TP-Link Kasa HS300

TP-Link Kasa HS300 and KP303 offer a range of features to make controlling your appliances simpler and more convenient. Both devices can be controlled remotely through the Kasa Smart app, which is available for iOS 10 and Android 5.0 and higher.

Some features of the HS300 and KP303 models available on the app include:

• Schedule. You can set a schedule to turn the smart outlet on or off at a specified time.

• Timer. You can also set a countdown timer to automatically turn on or off the smart outlet after a specified amount of time.

• Runtime. This feature allows you to keep track of how long each outlet of your smart power strip has been working.

• Scenes. A scene is a preset group of smart devices that can be activated simultaneously with a single command, allowing you to easily set the mood to fit certain activities or special occasions. For example, you can set a "Movie Night" scene that will turn off your lamps and turn on the TV and sound system.

• Groups. With this feature, you can group together a number of outlets of your smart power strip for unified management.

• Away mode. This mode allows the smart outlet of your power strip to turn on/off automatically at random intervals while you are away to make the appearance that someone is home, deterring potential intruders.

• Smart Actions. This feature enables device interconnections and home automation, allowing your Kasa devices to work together to create a seamless smart home experience. For example, if you have a Kasa camera with motion sensing, you can set up a smart action that turns on the smart outlet of your KP303 or HS300 when motion is detected.

When it comes to features, the key difference between TP-Link Kasa HS300 and KP303 is the energy usage feature. With the HS300, you can see how much energy each outlet of your smart power strip is consuming, allowing you to make adjustments to save energy. This feature is not available in the more affordable KP303 model.
