Blackt Electrotech BT72PM3 Plug-In Energy Meter (3-Pin, 230V)

<p>Everyone complains about the electricity bill; almost nobody knows which appliance is causing it. This plug sits between the wall socket and any device — geyser, AC, fridge, gaming PC — and shows live watts, voltage, units consumed and running cost on an LCD, so you can finally settle the argument with data instead of guesswork.</p><p>Run it on one appliance for a week, note the units, move it to the next. It is the cheapest way to find the silent power drain in an Indian home, and it needs no app, wiring or electrician. Rated 4.3 out of 5 across 269 ratings on Amazon.in.</p>
