Rank #1 in Best Smart Plug 2026: 10 Ranked, and Why 13 Amps Means Three Different Wattages
Tapo P110 Smart Plug with Energy Monitoring, Max 13A, 2-Pack
Price and rating as shown on Amazon when we collected them. Both change.
The TP-Link Tapo P110 is an energy-monitoring smart plug sold here as a two-pack, and it takes first place in our smart plug ranking. At GBP 15.97 for two it works out at GBP 7.99 a socket, which is a quarter less than the same plug costs bought singly. Everything on this page comes from its Amazon listing rather than from our own testing.
The specification table is worth reading closely, because it does the arithmetic in front of you and then uses the wrong voltage. It publishes a current rating of 13 amps, an operating voltage of 220 volts and a wattage of 2,860 watts, and 13 times 220 is exactly 2,860, so the sum is internally perfect. British mains, however, has been 230 volts nominal since 1995. At 230 volts the same 13-amp relay carries 2,990 watts, and rival plugs that declare 240 volts sell the identical component as 3,120 watts. Same switch, three different ceilings, depending only on which voltage the listing chose.

Questions people ask
How many watts can the Tapo P110 actually take?
The listing gives a current rating of 13 amps and a wattage of 2,860 watts, which is 13 amps at the 220 volts the same table declares. British mains is 230 volts nominal, where 13 amps carries 2,990 watts. Either way, 13 amps is the ceiling, and a 3kW kettle or heater sits right at it.
Does it need a hub?
No. The listing sells it as an easy setup with no hub required, connecting over Wi-Fi and working with Amazon Alexa and Google Assistant for voice control.
What does the energy monitoring actually show?
TP-Link sells the P110 on energy monitoring, and the specification table gives the wattage ceiling. The listing does not publish an accuracy tolerance for the measurement, so treat the readings as a guide rather than a meter reading.
Why does the listing say the connector type is Schuko?
That is what the specification table says, and it does not match the product: Schuko is the round two-pin continental European plug, which does not fit a British socket. The plug shown and sold is a British three-pin type G. It is a catalogue field filled in wrongly rather than anything about the hardware.
How big is it and will it block the second socket?
The listing gives 7.2 x 5.1 x 6 centimetres and describes the design as compact. It does not say whether it leaves a double socket usable, so measure your own if that matters.
Is it one plug or two?
Two. This listing is the two-pack, which the table records as "Number of Items: 2", and at GBP 15.97 that is GBP 7.99 per socket.
