Plug this electricity meter into your appliances to see their true efficiency. This meter can measure voltage, wattage, current strength, CO₂ usage, electricity costs in kilowatts per hour, and more — in real-time. Now you’ll know if it’s time to replace that old dryer with a new energy-efficient one. It comes with overload protection, which notifies you when the unit is drawing more electricity than a circuit can safely handle. Unlike other power meters out there, ours features a large LCD screen with a clear-digit display, making it extra easy to view your real-time electricity usage and cost readings — even when you’re not close to the meter. With a built-in battery backup feature, this power meter will save your electricity usage readings, cost readings, and all settings during the event of a power outage
