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

I needed one of these instruments for two projects in my home. I'm absolutely delighted with its functionality and its elegant design. reliability. I really don't see a single feature about it that needs improvement ! However, because I've owned it for merely a few weeks I can't yet speak of its reliability. However, if and when it suddenly fails I'll immediately update this review with an assessment about. Thus, if you see no updates to this review, you can be assured that mine is still functioning like new.My uses for it so far :1. 20 air purifiers ( We have 5 cats sharing our home. ) that together add up to a lot of electricity. Their fan motors each have PF correction circuitry, but those circuits can "wear out".2. Many red LED phototherapy lamps for use in 120 vac floorstand and tabletop fixtures. Each of these each have integral AC-to-DC converters, and these power supplies each contain a transformer. The PF of these lamps varies --- depending on the manufacturer and the cumulative number of usage hours.

Muy fácil de usar, da muchos datos la pantalla

This one has the best information on each screen IMO to reduce how often you have to change screens. That is why I bought this one.However, it does not fit into either of the 2 styles of wall outlets I have in my house because the ground pin is too long. In order to use this power meter, I have to plug a multi-plug into the wall and then plug this power meter into the multi-plug. It's possible my wall outlets don't have deep enough ground sockets, but everything else fits in my wall outlets without a problem.One annoying part of the device (assuming it fits your outlet) is the reset button. You have to use a small tool (included) or a paper clip to push the reset button, and you'll want to reset it each time you use it unless you have a reason to keep old data. There is an internal battery that keeps old data for whatever reason. I can't think of a use for the battery personally.The text is difficult to read when the backlight is off. This makes the backlight necessary instead of an enhancement. I wish they would've just used a better screen and skipped the backlight. One thing to know about the backlight is that the backlight turns off automatically after 30 seconds. Whether that's good or bad is up to you.Despite the marketing claiming this supports 3680W, it only supports 16A of current. 16A*230V is 3680W, but 16A*120V=1920W in the US. Don't buy this thinking it will support 20A of current in the US (or anywhere) just because it supports high wattage. It even has the North American style of plug, so you shouldn't be plugging it into much more than 120V most likely.

WORKS FINE,NO problems.

Funciona bien, por el momento no he tenido la oportunidad de comprobar con un dispositivo más confiable, pero por el momento el funcionamiento está muy bien, por el momento confío en que la lectura es correcta

I bought the Suraielec meter and a similar-price Ketotek meter to compare them. Both are reasonably easy to use, but the Ketotek has somewhat larger buttons for switching between modes. The Ketotek is also MUCH easier to reset when you want to restart the power usage measurement. All the functions worked as advertised on both units. I did not test for accuracy against a known reference, but the voltage was 120 +- 0.2 as expected. All other measurements looked reasonable for our toaster oven. The back-lighting makes the data very easy to read on both units. The Suraielect back-lighting goes off after about 20 sec (my preference), and comes on again when you next push a button. The Ketotek back-lighting stays on for several minutes, and also returns when you push a button. The biggest difference is in how you reset the cumulative kWh and time measurements. To reset the Ketotek, you push the + and - buttons simultaneously for 3 sec. To reset the Suraielec, you have to stick a small clip (provided) or a paper clip into a small hole. That's a nuisance and requires you to keep a paper clip handy when using the device. Consequently I returned the Suraielec and ordered a second Ketotek.

After receiving Meter I found 20 different systems using large amount of power when shut off. After unplugging new electric bill dropped by $20. a month.

Contact address given on the Suraielec website is invalid. I attempted to contact them with my problem device and my email was kicked back with a fatal error, undeliverable.The watt meter delivered was DOA. Well, not precisely...it allows entry of cost per kwh, and displays line hz and overload setting...everything else is zeroed out. I bought this specific unit for its high maximum overload of 3680 watts because previous meters I bought would redline on my 1800 watt induction cooktop. But the others work fine in all other aspects as designed with that overload limitation. The Suraielec unit simply does not function.I foolishly disposed of the packaging, so I can't return it. And since I can't contact the seller, I'm out $17 with a not very good paperweight.
