Great for a while but wouldn't recommend

I don't "HATE" the product because it worked and did what I wanted. MY problem is that the device suddenly stopped working and the manufacturers ignored repeated attempts to contact me. I would recommend another brand.

  • Sturdy construction
  • Something different

Died after about a week of use

Completely died after a week or two of use. Nothing is displayed on the screen, the device is not powered. The device still works perfectly when plugged in directly without Kill a Watt. It's good that I didn't go on holiday with the fridge connected, that would have broken.

  • Dope 🔥
  • Was damaged

They should rename these devices disposable monitors already fried 2

They should put a disclaimer on them, they are NOT designed to continuously monitor anything over 1400 watts or so. This thing caught fire after 3 days of continuous monitoring of 1475 watts. Although the maximum value is 1875 VA, this is not monitored for long. If you plug something close to 1800 watts it will most likely melt the block or fuse. What this can do is check how much current you are using for baseline and then turn it off.

  • Easy to read control panel
  • There are problems

Right, a continuous load of 1600W (1800W max) killed it. I checked and it looks like the thermal fuse has blown. I sent an email asking for a warranty replacement, but I'm not optimistic. Update - No response after a few weeks. A product failure below the nominal design appears extremely suspicious. Especially since the fuse in question should reset when it has cooled sufficiently. The fuses seem cheaper. Be prepared to treat them once.

The standard by which all other power meters are measured. Don't go wrong with any of these, buy one. At least I thought you couldn't go wrong. But I just hooked mine up to a 110V AC source coming from an inverter in a solar PV array and the "modified sine wave" seems to have fried it right away. Now he's dead as a doornail. So this is a little Easter egg for those who actually read device reviews with tons of reviews. Beware of use with modified (cheap) inverters. Worked well with my pure sine

  • One year trial
  • Not bad

Incorrect readings, no support from mfg, scrap

The thing is scrap. Mine reads over 9V/A even with nothing connected to it! This renders this device unusable for monitoring power consumption of relatively underperforming devices such as wireless routers, standby use of small appliances, etc. I have tried to contact Kill-A-Watt several times to no avail. I checked this too. compared to an expensive Fluke DMM with higher power loads and poor accuracy. The voltage is within a few percent, but the current reading can differ by more than 10%…

  • cool product
  • slightly dented

I'm disappointed.: Accessory

I bought it in October 2017 and really didn't use it much. Today I tried to measure the power consumption of a small AC device. The ground pin on the 4400 came loose. A call to technical support did not help. They said the warranty was expired. I opened the unit and I can't tell if the ground pin is screwed or soldered. At least not very strong. I'm disappointed. Note that the ground pin is not connected to the circuit involved in the measurement. Actually he just sits. However, it's a little…

very handy device!

Received this multimeter about a week ago. I try to save where I can and was curious how much energy everyday devices use. My electric bill is reasonable, but I want to save money. So I went around and hooked up this meter to some of my devices and below is what I found. Vicks Warm Mist Humidifier 360W. consumes 2.45 kW for 8 hours. Bissell Upright Bagless Vacuum Cleaner - 954W (WOW) Acer Chromebook Charger - 46W iPhone Charger - 5W Small LED Bulb - 9W Digital Photo Frame 7" - 3.6W Pelonis 20"…

  • Stylish and modern design
  • So far so good

six years ago on Meter Sockets

I bought the P4400 in 2011. He showed which household items were energy vampires, some of which used as much electricity when turned off as when turned on. I could turn them off with extension cords or turn them off when not needed. By measuring the power consumption of internet-connected devices, I was able to estimate how much time a given UPS would give me in the event of a power outage. I kept a table. the performance of various elements under various conditions to aid in future…
