KETOTEK Watt Meter Power Meter Plug — Home Energy Monitor with LCD Display & Overload Protection

The KETOTEK Watt Meter plugs between the wall outlet and your appliance to reveal how much energy a device uses in real time. Compact, simple to place, and designed for everyday home use, it helps you understand consumption without guesswork. The bright LCD keeps readings legible from across the room, making energy awareness approachable for everyone.

Simple, intuitive controls

Choose from a five button interface for quick access to key parameters. Each press reveals a different view:

• Press M to display kilowatt hours and estimated electricity cost
• Press + to show Watt (active power) and VA (apparent power)
• Press OK to display true RMS voltage Vrms and true RMS current Arms
• Press - to display Hz and PF
• Press ↺ to display maximum and minimum power
• Hold OK for 3 seconds to display the complete accumulated time

Monitor home appliances with ease

Install the meter between the outlet and your device to measure usage. It works with common household electronics and appliances such as computers, gaming consoles, printers, TVs, refrigerators, washing machines, dryers, and routers. The device starts measuring when the appliance runs at more than a small threshold, showing how consumption translates to energy cost.

Protection that helps you stay within safe limits

The meter includes smart alerts if load power, KWH, or cost exceed your set thresholds. The display shows overload, KWh ALARM, or COST ALARM, and a LED indicator flashes to draw attention. The default overload is 3680W and is adjustable, with a recommended starting point around 1800W.

Reliable data storage and clear readability

A built in high precision chip stores data even if power momentarily fails, so you can review trends after reconnection. It also resets measurements without losing your saved settings, so you can compare multiple devices with the same unit. The upgraded LCD offers wide viewing angles for easy reading from different positions.

Realistic, practical benefits you can explore

Use readings to estimate running costs, compare devices, and plan energy use across a busy home. While numbers reflect current usage, they indicate possibilities rather than guarantees, empowering you to make informed choices.
