Will a smart plug work with any outlet?

Standard US smart plugs fit standard US 2-prong and 3-prong outlets (NEMA 5-15). Most smart plugs are rated for 15A — the standard residential circuit amperage. Avoid using smart plugs for high-draw appliances like clothes dryers, air conditioners, or electric vehicle chargers — these require dedicated 20A+ smart outlets or switches. Check the device wattage before plugging in: a 15A/120V plug handles up to 1800W safely.

Can I use smart plugs outdoors?

Standard indoor smart plugs should never be used outdoors — weather exposure risks short circuits and fires. Outdoor smart plugs have weather-resistant housing (IP44 or higher) and are specifically rated for outdoor use. Wyze Plug Outdoor (B08NXY7WWX) and Kasa EP40 are designed for outdoor patio, landscape lighting, and holiday decoration control.

Do smart plugs use a lot of electricity?

No — a typical smart plug draws 0.3-1W in standby mode. Running one 24/7 costs roughly $0.50-1.50 per year in electricity. The energy savings from automating high-draw devices (turning off space heaters, PC setups, and entertainment centers when not in use) easily outweigh the smart plug's own consumption.
