Poniie PN1500 Portable Micro Electricity Usage Monitor

The Poniie PN1500 is one of the most trusted electricity usage monitors on the market. It’s one of the cheaper products in Poniie’s range but you get a lot of the same features as the more high-end monitors. For example, the refined accuracy ensures best-in-class accuracy (0.01W, 0.1V & 0.01A resolution), so it doesn’t matter how much you spend, you won’t get a more accurate monitor. On the front of the monitor, there are five independent keys allowing you to access different power parameters quickly. It also has a built-in memory for cumulative kilowatt-hours and elapsed time.

This might not be the most advanced electricity usage monitor on this list but it does the basic things really well. It’s also protected by a one-year warranty, which means you can buy with confidence.

If you want to save a bit of money and still get a P3 Kill-A-Watt, you can get this model – the P3 P4400. We already featured the P3 P4460 earlier on this and this is the slightly cheaper version. Honestly, there isn’t much to separate the two models. This model still provides you an easy way to keep track of your energy usage. The only difference is that this model doesn’t have an in-built memory, so when you unplug it from the wall outlet it loses all of its data. The P3 P4400 has an easy-to-read LCD display, five quick-access buttons, and can be used to monitor electricity usage by day, week, month, or year.

If you want more detailed information about your electricity usage, the Sense Energy Monitor is the product you need. Get an electrician to install the Sense monitor into your electrical panel and it will send all of the information you need to your smartphone. Find out information like how much the washing machine costs per wash, when the TV was turned on and off, and how many times you use the microwave in a week. Information like this gives you a much more informed approach to saving on your electricity bill. At nearly $300, it might seem like a lot of money for an electricity usage monitor but if you use a lot of high-energy appliances, you could end up saving $300+ a year on your energy bills.
