Works As Advertised, Resistive Load Rated only
Reviewed in Canada on December 21, 2018
I like the product, it turns my lamp on as intended. It is marked as UL,NOM,ANCE,FCC, and ICES certifications or compliances. Oddly there doesnt seem to be any CSA mark though.
Most people seem to forget that this thing (and most other similar smart plugs) have a tiny little relay in it, and these little relays are only rated for resistive loads, see below:
Resistive and Inductive Loads
Relays are often rated for switching resistive loads. Inductive loads can be very hard on the contacts of a relay. A resistive load is a device that stays electrically quiet when powered up, such as an incandescent light bulb. An inductive load typically has a violent startup voltage or amperage requirement, such as a motor or a transformer.
Startup and Runtime Loads
Inductive loads typically require 2-3 times the runtime voltage or amperage when power is first applied to the device. For instance, a motor rated at 5 Amps, 125 VAC will often require 10-15 amps just to get the shaft of the motor in motion. Once in motion, the the motor may consume no more than 5 amps. When driving these types of loads, choose a relay that exceeds the initial requirement of the motor. In this case, a 20-30 Amp relay should be used for best relay life.
As per that description, dont use these things with high amp load devices, especially ones with big motors or heating elements in them, this can be potentially fire causing.
