How much did the fridge in the garage cost?

Plug it in, restart it, let it sit for 24 hours and 2,224 kW then I can count per day, per month, per year. This answered my question. made me happy

  • Great for me

No problem, lack of backlight may bother some

I've been using it for a few months now and have no major complaints. The only disappointment - the lack of a backlight - is unreadable from odd angles or in the dark.

Highly recommended for Electric

I've waited months to write this review and it seems like a very reliable product, I can't speak to its accuracy but it has held up very well. It is very useful to get an idea of the dimensions of the generator and the total current consumption. I highly recommend

Fire Hazard: Breakers, Load Centers and Fuses

This has worked great for about 6 months. One day it smelled burnt. The block melted on the fork. If we weren't at home, it could be dangerous. The company replaced the device free of charge, stating that the connection sometimes becomes loose during shipping and a short circuit can occur. The new block lasted about three weeks and then also melted onto the connector. I won't try any other as the fire hazard is too great.

English Guide

I don't know who wrote this guide but they need to get out on the sidewalk and find someone who speaks sixth grade English to help them. To set the cost per kWh, the function must be pressed until the cost/KWH value is shown below. Press and hold the Cost button for more than 2 seconds until the cost starts flashing. Press "Function" button to make the digit you want to set blink, then use "Up" or "Down" button to set it. Then press the function to set another digit. When you're done, click…

Almost burned down my house!

Buy this to try and limit your energy consumption. It had been plugged in for a week when all of a sudden I smelled burning plastic and saw magic smoke coming out. He didn't turn off the switch, if I hadn't caught him the fire would have started. The scary thing is that I left it plugged in when I left town for a week. I did not restart the device and no warnings ever appeared. If you value your property, spend the premium and get a brand counter. This is complete garbage and a fire hazard.

  • Quality construction
  • Something different

The seller doesn't even know how the time function works!

The seller clearly stated that time does not stand still when the load is removed. But it is so and it sucks! So I just returned another version of these gauges (same OEM board I'm sure) which had a very nice backlit display which this one doesn't have. Why? I did this because the seller of these gauges said (twice) in the questions section that this gauge measures wall time, not the number of minutes it senses the load. You need this time if you want to calculate useful things like kWh/day…
