Four-pack Wi-Fi smart plug kit

The Tenda SP3 4pack supplies four plug-in modules that connect to a 2.4GHz IEEE 802.11b/g/n network and are managed through the BeLi app. Each unit handles up to 10A and 1.2KW at 100-120VAC, making the set suitable for lamps, fans or small appliances throughout a home. Voice control works with Amazon Alexa and Google Assistant for hands-free operation. Compact dimensions of 2.52" x 1.50" x 1.30" keep adjacent outlets free.

Compatibility checklist before ordering

Verify that the installation site has a 2.4GHz Wi-Fi network, as the plugs do not support 5GHz bands. The BeLi app requires Android 4.4 or higher or iOS 9.0 or higher on the controlling phone. Each outlet must supply 100-120VAC and the connected load must stay within the 10A, 1.2KW limit. UL, FCC and RoHS certifications are listed for the hardware.

Behaviour under continuous load

The plugs are rated for a maximum of 1.2KW at 100-120VAC and an operating temperature range of 0°C to 40°C (32°F to 104°F) with 10% to 90% non-condensing humidity. Sustained operation near the 10A limit should remain within these thermal and humidity bounds to maintain reliable switching. The power LED provides a visual status indicator during extended use.

Questions about this item

What comes in the box and is anything else needed to start using the four plugs?

The box contains four SP3 smart plugs and a quick installation guide. No extra hardware is required; you only need a 2.4 GHz Wi-Fi network and a phone running Android 4.4 or iOS 9.0 to run the BeLi app.

The pack contains four identical units — how do I decide where to use each 10 A, 1.2 kW plug?

Each plug handles up to 10 A and 1.2 kW at 100–120 VAC, so match them to lamps, fans, chargers or small appliances that stay within those limits; avoid heaters or large motors that would exceed the rating.

What does the 2.4 GHz 802.11b/g/n rating mean for everyday response time in my home?

The plug connects on the 2.4 GHz band using 1T1R 802.11b/g/n, giving reliable coverage through walls for on/off commands, scheduling and voice control via Alexa or Google Assistant.
