Kasa vs EIGHTREE Smart Plug Specs
Connectivity
Kasa Smart relies solely on 2.4GHz Wi-Fi for all connections. You must use the Kasa app to set up and control the plug. EIGHTREE offers a dual approach. It supports 2.4GHz Wi-Fi but also includes Bluetooth. This allows for faster initial pairing via the Smart Life app. Bluetooth can help stabilize the connection during setup. If you prefer a simpler setup process without needing to open a specific app immediately, EIGHTREE has an advantage. Kasa requires you to open the app and follow instructions for every connection. Both require 2.4GHz networks. Neither supports 5GHz Wi-Fi. Your choice depends on whether you value the extra Bluetooth option for setup stability.
Certification
Safety certifications are important for high-load devices. Kasa Smart holds UL certification for safety use. This is a widely recognized standard in the United States. It also mentions being a Reader’s Choice of PCMag 2020. EIGHTREE lists FCC and ETL certifications. ETL is also a recognized safety testing organization. Both products meet necessary safety standards for home use. Kasa provides a 2-year warranty, which adds to its reliability profile. EIGHTREE does not list a warranty period in the provided data. If you prioritize a longer manufacturer warranty alongside safety checks, Kasa is the stronger choice. Otherwise, both are certified for safe operation with high-power appliances.
Smart Home Compatibility
Both plugs work with Amazon Alexa and Google Assistant. This covers the majority of smart home users. EIGHTREE adds SmartThings to its compatibility list. This is a platform for Samsung devices and other smart home integrations. If you use SmartThings or have a Samsung ecosystem, EIGHTREE offers broader support. Kasa sticks to Alexa and Google Home. It does not list SmartThings in the key specs. For most users, Alexa and Google are sufficient. However, if you need integration with SmartThings routines, EIGHTREE is the only option here. Both support voice control for hands-free operation. You can turn devices on or off using voice commands with either brand.
Form Factor
Size matters when outlets are crowded. Kasa is a rectangular mini plug. It measures 2.03 inches in width and 2.36 inches in length. The height is 1.5 inches. It takes up standard wall space. EIGHTREE uses a compact round shape. It is only 1.2 inches thick. The width and length are both 1.9 inches. This slim profile allows it to fit behind furniture or in narrow spaces more easily. Kasa’s rectangular design might block adjacent outlets if they are close together. EIGHTREE’s low profile helps keep your home organized. If you have many plugs in one area, EIGHTREE saves more space. Both are white and fit standard US outlets.
Packaging Options
You can buy these plugs in different quantities. Kasa offers 1-Pack, 2-Pack, and 4-Pack options. It also has an Energy Monitoring style variation. EIGHTREE offers 1-Pack, 2-Pack, and 4-Pack options as well. Both brands provide flexibility for single or bulk purchases. Kasa’s Energy Monitoring variant allows you to track power usage. EIGHTREE does not list energy monitoring in its specs. If you need to see how much electricity a device uses, you must choose the Kasa Energy Monitoring version. Otherwise, the basic plug options are similar in quantity. Both allow you to start with one and expand later. The choice depends on whether you need data on power consumption.
Which Kasa or EIGHTREE plug fits you
Users with crowded outlets needing slim fit
The EIGHTREE plug measures just 1.2 inches thick. This compact round design fits behind furniture or in tight spaces where the Kasa model might not. You get the same 15A power handling but with a form factor that keeps your wall area clear and organized.
People wanting faster initial Bluetooth setup
EIGHTREE includes Bluetooth alongside Wi-Fi. You can use Bluetooth to help establish the initial connection to the Smart Life app. This often simplifies the pairing process compared to Kasa, which relies solely on 2.4GHz Wi-Fi for setup and control without any local Bluetooth assistance.
Shoppers preferring individual unit purchases
Kasa offers a 1-Pack option for the EP10 model. If you only need to automate a single device right now, this lets you start with one unit. EIGHTREE primarily lists 4-Pack, 2-Pack, and 1-Pack options, but Kasa’s established brand presence and UL certification may appeal to solo buyers.
