Best For determining Power: Suraielec powermeter

Buy on Amazon

Suraielec has been making great meter for years, thanks to a combination of clever design and appropriate materials. The LCD display can only be seen when viewed directly from in front of the display at eye level. You simply plug it into a wall socket, plug in your electronic device, and it gives you real-time readings of how much power is being consumed, as well as the highest wattage that your product hits. It measures one device at a time unless you plug things like electronics into a power strip, then it will measure the usage of all of these at the same time.

The only area of improvement on this product is that the "reset" button is a tiny recessed button that needs an unbent paper clip to press. The watt gauge is very helpful to see what a device is drawing from the power line. They raise electricity prices progressively from 1PM to 3PM to 7PM on weekdays. If you want to see the display and it is plugged into a standard wall outlet you have to kneel down on your hands and knees down on the floor to see the display at eye level.

Buy on Amazon

We would, of course, be remiss if we didn't mention bnlink powermeter for daily usage. This power meter is very easy to use and set up. It features to calculate power and energy usage. Even if you plug it into the top plug of an outlet, it has a rounded bottom which blocks the lower outlet from being used. It is meant to be plugged in constantly unless you need to monitor your "cost" minute by minute.

This works just as well as Kill-A-Watt and has more features. It only checks the current draw in wattage, but it does not measure min and max power. It is very hard to read even in well lit and at a comfortable distance. It's easy to use, plug it in and press one button to cycle through displays. There is a manual reset button.
