Rank #4 in Best Smart Plug 2026: 10 Ranked, and Why 13 Amps Means Three Different Wattages
EIGHTREE 5GHz Smart Plug with Energy Monitoring, Max 13A, 4-Pack
Price and rating as shown on Amazon when we collected them. Both change.
The EIGHTREE ET35 is a 5GHz smart plug with energy monitoring, sold here as a four-pack, and it takes fourth place in our smart plug ranking. At GBP 34.99 for four it comes to GBP 8.75 a socket, a figure Amazon prints on the listing itself, against GBP 7.99 from either Tapo multipack and GBP 8.50 from the Meross two-pack. Its selling point is the radio: the listing leads on 5GHz Wi-Fi, and EIGHTREE's own comparison table sets this model against a 2.4GHz-only sibling.
Its specification table also does something none of the bigger names in this ranking manage. It gives a current rating of 13 amps and a wattage of 2,990 watts, and its comparison table gives a rated voltage of AC 230 volts. Thirteen amps at 230 volts is 2,990 watts exactly, and 230 volts is the real figure for British mains, which it has been since 1995. Of the four listings in this ranking we have taken apart in detail, this is the only one that lands on it: the Tapo P110 declares 220 volts and 2,860 watts, the Meross MSS305 declares 240 volts and 3,120 watts, and the Tapo TP11 publishes a voltage with no current rating at all. Same 13-amp relay, three different ceilings, and the one that is right belongs to the least famous brand of the three.

Questions people ask
How many watts can the EIGHTREE ET35 take?
The table gives 13 amps and 2,990 watts, and the comparison table gives 230 volts. Thirteen amps at 230 volts is 2,990 watts exactly, so this listing agrees with itself and with the real voltage of British mains. A 3kW kettle or heater still sits right at the limit of any 13-amp socket.
Why does it quote a different wattage from the Tapo and Meross plugs?
Because they use different voltages. The Tapo P110 declares 220 volts and gets 2,860 watts, the Meross MSS305 declares 240 volts and gets 3,120 watts, and this one declares 230 volts and gets 2,990 watts. The relay is 13 amps in all three. Only the voltage in the form changes, and 230 volts is the current British figure.
What does the 5GHz support actually mean?
Most smart plugs join a 2.4GHz network only, which is why setup often means splitting your Wi-Fi bands. EIGHTREE sells this model on working with 5GHz as well, and its own comparison table puts it against a 2.4GHz-only sibling. Several of the reviews on the listing are specifically about that.
Does it need a hub?
No. The listing describes control through a smartphone app with voice control via Alexa and Google Home over Wi-Fi.
How many plugs do you get?
Four, and unusually for this ranking the listing says so consistently: "Number of Items" reads 4 and "Unit Count" reads 4.0. The Tapo TP11 four-pack gives three different quantities on one table, and the Meross two-pack gives two.
How big is each plug?
The listing does not publish dimensions. It gives 380 grams for the four-pack, which is 95 grams a plug. One four-star reviewer notes the pins are a tight fit in a UK socket.
