Watt Meter

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.

The Suraielec Watt Meter is a fantastic tool for monitoring home energy use. It supports a wide voltage range (90V-250V) and features a large backlit display that’s easy to read. The auto cost calculator helps track expenses accurately, and overload protection adds safety. Setup was simple, and it provides precise readings of watts, amps, and voltage. Ideal for anyone wanting to save on electricity bills. Highly recommend!

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.

Very functional.

I like this meter because it has memory and a backlit display to allow easier viewing than the Kill-A-Watt models.Also has max power usage indications.The reset button is hard to activate unless you use the included tool or have a pen tip handy.

Feature rich, but with limited functionality. Primary reason for this purchase was to measure a refrigerator's start-up power causing house lights to dim. The Suraielec Watt Meter failed. It did NOT see or register any impulse current, it just showed the average low power value. So, I still don't know how close the fridge is to tripping the circuit breaker. Would have paid more for that feature, but Suraielec claimed it "ensures precise readings" and measures "max/min power". Not so.

i love the features this thing displays, less math and guessing involved.

Muy recomendado, cumple con todas las funciones y es muy preciso
