What the maker puts in writing

  • 4 plugs · 120 V / 15 A / 1,800 W
  • Dual-band Wi-Fi including 5 GHz
  • Bluetooth-assisted setup
  • Alexa and Google Home via Smart Life
  • Schedules, timers, group control

One radio, one problem solved

The 5GHz band delivers smoother, low-latency control when you’re near your router.

That is the maker’s framing. The more useful framing is the one it does not say: every other plug on this shelf will not connect to a 5 GHz network at all, and on a router that merges both bands under one name, that turns a five-minute job into an evening.

What it gives up

No certification named — four plugs on this shelf publish ETL, UL or FCC — and no Matter. The same maker’s cheaper four-pack here publishes both FCC and ETL.

Ten dollars a plug is the top of this shelf. The radio is the reason.

The questions that keep coming up

Why does 5 GHz matter?

Because most modern routers broadcast one network name across both bands, and a 2.4 GHz-only device cannot see it properly. Seven plugs on this shelf state 2.4 GHz only, several in capitals. If your setup has ever stalled at "searching for device", this is the plug that solves it.

Will it run a space heater?

Fifteen amps and 1,800 watts, published. A 1,500-watt heater draws about 12.5 amps, so yes, with margin. The two cheapest plugs on this shelf publish no rating at all, which is the number to insist on before plugging in anything that makes heat.

Why is it dearer than the same maker’s other four-pack?

The 5 GHz radio is the published difference. The EIGHTREE four-pack on this shelf gives the same 15 A and 1,800 W with FCC and ETL certification at 2.4 GHz only, for roughly half the price per plug.
