Plug-in Energy Monitor Power Meter

I just bought one of this power meter device over the web and it arrived on the 28 Sep 2017 for GBP7.20 an approximate. Personally, I find this device kind of big. I could not find a rectangular version of it. I too got the instruction stating that there is a battery for this device, but could not find the battery compartment likewise. I am trying it out now. I also ordered another power plug meter with the green buttons, on the way thru the mail system. I want to see how much power guzzling devices that are spiking my electric bill.

I did it quickly and efficiently with instructions from Avasva webpage.

Sub back please. I got this and cant get it to work at all. Mine lets power go threw but screen dont light at all. If any one knows a fix, pls reply, sub too as I am going to do similar things.

There is a battery inside. Just plug it in.
I have the same one (US model). The rear says Intertek, but the front says YouThink.
Same thing though.

Thank you

How is the device holding up? Have you had any problems ?

I bought 5 from 4 different suppliers and returned the lot. They couldn't even record the time correctly which gave me no confidence in the electrical measurements!

how the hell do u get the timer to start? i must have a bad one

not reliable switch for a fews days arcing at the neutral line and failed.

Hi, interesting video, I just got one and the same issue as you have, where is the battery,?! I thought if it's a rechargeable one then tryed leaving it plugged in over night, but still no sign of the battery's presence, Did you get any results with your own meter?.... BE interested to know what you done, Thanks... Thom in Scotland.

Hi, could you make a video on the teardown of this kind of device to know the design better

Cheers Kev thanks for the video.

How accurate is this?

have you tried to compare the result of this device in KWh with the average rms current from your dmm over a period of 1h x 230V, to see if it actually displays apparent (VA) or real power (W)? Or at least the instantaneous displayed power vs rms current from your dmm x 230V ?

Is it still functional? Did it explode? Many people say that smart plugs tend to explode, so I was wondering how safe is this one. Thank you

I have a question...please .... if I get a 12 volts mains powered car battery charger.......and connect a 800 watts inverter ......which converts the 12 volts dc to 240 volts ac ...and power up a 500 watts desktop computer ..... will I be saving on electricity .....I am on duel fuel at the moment and pay 00.29 pence a kwh .... is it a good idea ....or I won't save anything ...? .thanks

I had this plugged into my printer that was in sleep mode for a 24 hour period. When I looked at the cost it said 1.50. Probably a stupid question but is that 1.5 pence or £1.50?

Hey , could you summarize the proplems that you faced during your using of the power meter and what did you do to solve it . Its really important for me and thank you

No not useful you didnt do the cost

We’ve all got heat guns 🙄 Pity you didn’t test it with something like a kettle

I just want to know how to get the cost!

Is it possible to calculate the amount of power spent in £.

Can someone confirm that the hertz function is just a dummy and doesnt actually display real hertz value?... i bought 1 of these and hertz always stays at 60..exactly...i plugged it into a generator that i know was not 60hz and it showed 60

Urs shows 50hz cause u are in uk...but thats not right...ur hz will never be exactly 50...i believe the hertz does not show actual real value
