Review: Man don't think twice. It works and I love it. Shows volts amps and watts at the same time. Plug my coffee marker in to it and was surprised to see 9 amps of draw at 119 volts. Anyway that said that is why I bought. I can now see what and how much is on one circuit with ease. Review: Been having this ammeter/combo for over a month now on my 21cu/ft Hamilton Beach deep freezer to monitor cost-to-run. I FREAKING LOVE this product!! Great screen options (I leave it on cost per kWh by default). I especially love that I can set the wattage for overload-shutdown for safety. Having taken a week-long trip recently, I felt perfectly comfortable with it managing a shut-down if the freezer had malfunctioned. Awesome display and about as small as one can expect in the feature-set and capabilities. Feels solid and stays put in the outlet just fine. HUGE comfort bonus. On "that note," I was most impressed with how it WAS NOT BULKY compared to other meters offering similar features. I couldn't even get this larger "competitor model" to stay in the outlet…even without the cord plugged in!!! I'm very pleased with this purchase! 100% ## Features - Intuitive Electric Usage Monitoring: Measure power (W), volts, amps, frequency, power factor, max/min power (W), cumulative time, and energy (kWh) with this watt meter; Automatically calculate costs based on set prices and track home energy usage for efficient electricity savings; This watt hour meter makes managing your energy consumption easy - 90-250 V Wide Voltage Range: The amp draw meter measures 90-250 Vac, 0-16 AMP, and 0-3680 Watt, with overload indication adjustable from 680 to 3680 W; Adhering to Class 1.0 accuracy standard with 0.1 W, 0.1 V, 0.001 A, and 0.001 kWh resolution, this watt power meter ensures precise readings - Clear LCD Display with Backlight: The energy monitor plug features a wide-angle, clear-digit LCD display with backlight for easy reading and operation in dark environments; This wattage meter plug in provides excellent visibility - 90 Days Long-Term Data Hold Memory: Equipped with a built-in rechargeable battery backup, this appliance power usage meter stores data for up to 90 days during power outages or when unplugged; The reset button restores all data to zero, making it a reliable wattage meter for long-term use - Space-Saving Design: The compact design of this measure power usage device leaves the lower wall outlet accessible when plugged into the upper outlet; Made of high-quality fire-resistant material, this watt meter plug in is both safe and efficient; Ideal for those looking for a power meter plug, watt meter, or outlet meter ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CR9Z19DQ | | ASIN | B0CR9Z19DQ | | Batteries Included? | Yes | | Batteries Required? | Yes | | Battery Cell Type | NiMH | | Best Sellers Rank | #171,870 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #9 in Electrical Meter Sockets | | Color | White | | Customer Reviews | 4.5 4.5 out of 5 stars (430) | | Customer reviews | 4.5 4.5 out of 5 stars (430) | | Date First Available | 28 March 2024 | | Date First Available | 28 March 2024 | | Item Package Quantity | 1 | | Item Weight | 168 g | | Item model number | WMA02A | | Item model number | WMA02A | | Manufacturer | SURAIELEC | | Manufacturer | SURAIELEC | | Material | PC | | Package Dimensions | 14.1 x 7.49 x 6.91 cm; 168 g | | Package Dimensions | 14.1 x 7.49 x 6.91 cm; 168 g | | Part number | WMA02A | | Power source type | ac | | Voltage | 250 Volts | | Wattage | 3680 watts | ## Images ![Suraielec Watt Meter, Plug-in Socket Power Meter, 90V-250V Wide Range, Backlit Large Display, Auto Cost Calculator, Overload Protection, Kilowatt Wattage Voltage AMP Tester, Electricity Usage Monitor - Image 1](https://m.media-amazon.com/images/I/61YlkudCEAL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by G***M on 14 May 2025* Man don't think twice.
