User questions & answers

Question:	does it mearsure watts
Answer:	Time/Watts/Cost Time/Volts/Cost Time/Current/Power Plus two more modes
Question:	How do I install batteries and what size battery
Answer:	No visible battery door, hatch. Since it plugs into power when in use, if there is a battery, it's charging when being used.
Question:	Is this rated for 15a/1800w continuous? in other words, what happens if you connect it to an ev charger, which will draw 15a all the time
Answer:	Yes, rated15A continuous. Only draws about 1 watt (0.008 amps) by itself. Basically, it will draw what the EV charger draws. If you get one, you will see that the EV charger draws max load early, then power draw dwindles as the car gets closer to full charge. It will not draw 15A continuously. You will also be able to measure the watt-hour capacity of your electric vehicle's battery storage. Plus it makes you cool without smoking cigarettes. Very cool.
Question:	Having an issue with 2 outlets in my house and I need to track the power at them. When they lose power and when it came back.Do these keep history
Answer:	I dont think these are what your looking for. They do a great job tracking power used, but there isn't a function for testing outlets.

User questions & answers

Question:	Can I use it on a gas dryer that takes 30 Amps for a split second to start? I know it runs below 8 amps once started
Answer:	Its a crap shoot as to whether this meter can handle the surge current of start up. Maybe itll work once, twice, a few times. But eventually it WILL fail. Id recommend one of those add in power monitor displays with a split core transformer that is clamped around the input hot line to sense current. For example, a CrocSee CRS-022B. Much, much safer. And can sense up to 100A!
Question:	can be used connecting 220 Volts at 60 Hz
Answer:	Yes, this item is designed for 110-220v, 50-60hz, AC power.
Question:	Can you plug space heaters into it safely
Answer:	It depends, the max. wattage rating of the PN2000 is 1760w @110v or 2000w @125v (16 amps). As long as your space heater rating is lower than this, it should work. Most space heaters have a max. output of 1500W, so you should be good to go. Note: Due to the large start-up amps of space heater, though device has abilities to deal with it, we still recommend not to use the device near the max rated specs (in most cases, the true RMS Current will be around 15A) for a long time to avoid any unexpected damage or accident. And please kindly know that the inner and outer device material is fireproofing. If device is over used or exposure to excessive heat, it may cause a melt incident but it won't start a fire. Still, you need use this device carefully to avoid any fire hazard.
Question:	Does it tell you how much electricity has been used in 24 hours and the cost of usage
Answer:	Yes, it will give a total usage over any time period (loose power circuits will be fine, consumption kWh will be kept in memory). So you just need to let it run 24 hours and check the Electricity Consumption (EC). Regarding the cost of usage, you have to do the math. Here gives you an example: Let's say your billed KWH is 0.07 and the distribution charge is 0.04. Then the KWH charge $0.07 + distribution charge $0.04 = $0.11 per Kilowatt Hour(kWh) usage. So if your device is using total 2.4 kW-hrs(EC) per 24 hours (which is equal to 100 watts in one hour), then you are paying $0.11 per kWh * 2.4 kilowatts per day = $0.264 for each day of use. Hope this explains it better.

User questions & answers

Question:	Where can I download the user manual? The link on your product page is not working
Answer:	Mine came with a user manual such as it was. Take a few minutes and look on YouTube;it will be explanatory quickly! Good luck!
Question:	Will this meter read the wattage im putting back into the grid
Answer:	No.
Question:	How do you reset the usage? I don't need to reset the cost Kw/h, just the running totals
Answer:	Hello, 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, you could send the email to [email protected], we will be surely responsible to this problem. thanks
Question:	Does it for remote by a computer or cell phone?will it work with 220v
Answer:	Negative. Most of these devices are rated up to 1875 watts. That's 125 volts times 15 amps. If your electrical service panel is up to code, the 15 amp breakers in it should flip off at 1440 watts. That's 80% of 1800 watts (120 volts times 15 amps). I have one window unit wired for 20 amps...that's 1920 watts safely. I have used these devices with my 20 amp outlets and but please don't make a habit of using it continuously, it will get hot and potentially start a fire. There are 220V meters out there but I'm not familiar with any of them. Take care!
Question:	Is this model 220v (Non US) AC compatible? If not, which model is? Thanks in advance
Answer:	This is a 120-volt meter. I recommend that if you want a plugin meter than can handle 240 volts you look one for the appropriate electrical receptacle on the front. This one clearly has a standard 120-vold outlet receptacle.
Question:	does this work on 220v 60hz house outlet
Answer:	According to product specifications Line Frequency range is 47.0 - 63 HZ. If your outlet is configured to accept the P4460 you should be able to use it. Before you buy you may want to ask the manufacturer this question.
Question:	Can it be set for a period of time (such as 24 hours) and record usage only then
Answer:	Yes, this records the total power used by the device whether it is on or off or any mix. You just need to go to the screen kwh used. record the beginning # and at the end of time period (say 24 hours) record the end #. that is how many kwh it used. I used several of these for months to record the A/C use in our shared apt and paid the landlord for the a/c used so they don't complain about my electricity used. great device. now however, my apt has a 20a a/c wall unit. while you could get converter to regular 3 prong, not sure if this unit will go to 20 amps.Others who said no are simply ignorant of this devices menu. It ALSo shows, when on watts menu, the watts used when a device is running, or is off. so you can see how much your a/c or toaster oven or giant screen tv uses when on, or off.It also keeps the power kilowatt hours used even if unplugged or power goes out in its internal memory. so you can simply record the kilowatt hours at the begin of a month, then at the end of the month, subtract and multiply by your cost of electricity for the total $ / month the device uses.The dork who was our landlord at the time thought his electric water heater for tea was less expensive to use than nuking a cup of water for a minute to heat it up in the microwave. popped this device on it and they were almost identical in total power used to heat a cup of water.The same idiot who was complaining about this left his rear projection tv on when he wasn't around, and they use alot more electricity than today's flat panel screens.If you want to record the power usage of some device over time, you'll want to plug this device into a short extension cord. if you plug it directly into the wall then you have to lie down on the floor to read the kilowatt readings. I just put the readings into a spreadsheet when I was recording monthly electricity usage.
Question:	To how many decimal places does this one display for Watts
Answer:	This EZ model does NOT display how many Watts you device is pulling... It displays how may kwh have been used thus far, to the 1/10th decimal place. So, when you first plug something in is shows ZERO, since not enough time has passed to show kwh used yet. This is a HUGE feature left off this device. For me, I want to plug something in to a meter like this and be able to instantly see how many Watts the device uses, and this EZ meter version does not do that.
