Electricity Usage Monitor Digital Wattmeter AC Power Meter 110V-230V Energy Meter Socket Power Monitor EU/US/UK/BR PlugIt's no secret that electricity bills are on the rise. With power meter you can cut your energy costs and find out what appliances are actually worth keeping plugged in by finding power-wasting appliances. Simply connect any appliance to the Wattmeter, it will then assess how efficient each appliance really is.Power Meter Feature Monitoring Electric Usage and Know Cost Intuitively Power consumption meter can measure power (W), volts, amps, frequency, power factor, maximum and minimum power (W), cumulative time and energy (kWh), and calculate cost automatically after price-setting; monitoring home energy usage and help you to save electricity cost Large Clear LCD Display with Backlight Electricity monitor kilowatt meter has a wide view angle and clear-digit display; easy to read and operate the electricity monitor in dark areas with the backlit clear LCD display Long Time Data Hold Memory Function Come with built-in rechargeable battery backup, the watt meter power analyzer can hold data up to 90 days when coming across a power outage or plugging out the meter from the outlet; all data includes the cost setting will go to zero once press the reset button Potable and Takes up 1 Outlet Only Compact size; power meter socket plug leaves the lower wall outlet available when plugging into the upper outlet; made of high-quality fire-resistant material; friendly after-sale customer service and 1-year limited ; Note: do not compatible with AC inverter and solar power inverter Dual Voltage Wide Measuring Range This power monitor meter can measure 110-130 Vac & 200-240 Vac voltage; 0-16A AMP; 0-3680W wattage, and indicate overload when load up to 3680W; Class 1.0 accuracy standard with 0.1W, 0.1V, 0.001A and 0.001kWh resolution; Note: Label on watt meter back only shows low volt range due to certification requirementsEU Plug Specifications:Operating voltage: 230V acFrequency display: 50HZWide voltage range 230V.---250VOperating current: max16Awattage display(watts)0w----3680wCurrent display(amgs) 0.0A-16.0APrice display range 0.00/KWH---99.99KWHTotal Kwh and cost display0.000KMH-----9999KWH000-9999US Plug Specifications:Operating voltage: 120V acFrequency display: 60HZWide voltage range 110V.---130VOperating current: max 15Awattage display(watts)0w----1800wCurrent display(amgs) 0.0A-15.0ATotal Kwh 0.000KMH-----9999KWHUK Plug Specifications:Operating voltage: 230V acFrequency display: 50HZWide voltage range 230V.---250VOperating current: max 13Awattage display(watts)0w----2900wCurrent display(amgs) 0.0A-13.0ATotal Kwh 0.000KMH-----9999KWHFrance Plug Specifications:Operating voltage: 230V acFrequency display: 50HZWide voltage range 230V.---250VOperating current: max16Awattage display(watts)0w----3680wCurrent display(amgs) 0.0A-16.0APrice display range 0.00/KWH---99.99KWHTotal Kwh and cost display0.000KMH-----9999KWH000-9999Brazil (BR) Plug Specifications:Operating voltage: 250V acFrequency display: 50HZWide voltage range 230V.---250VOperating current: max 16Awattage display(watts)0w----2500wCurrent display(amgs) 0.0A-16.0ATotal Kwh 0.000KMH-----9999KWH Package included:1 * Power MeterQuestions & AnswersQ1: Can i swivel the display part to show upright if the socket is sideways?A1: Unfortunately, the display part can't be swiveled, but it has the memory function. The data will stay even if you plug it out.Q2: Can I use to accurately measure inrush current? Does it register and save such brief spikes in current? A2: It will display amps or watts and you can see a surge on the display, as say the capacitors charge up in a power supply, or an electric motor draws more power on start up, but it won't store these transient values.Q3: How do you reset the usage? I don't need to reset the cost Kw/h, just the running totals.A3: This usage will be reset all, and then you could set the cost again, if you have any problem when reset, please tell us the details
