Counting Amps February 19, 2008
I don't normaly set time to do a review but this product is just a must for people that are trying to use a portable generator properly. The digital readout is clear and quite accurate as specifified by manufacturer's specification sheet. This load tester is well worth the price as compared to other Load testers on the market that can cost up to $150.00. Also for all you that are trying to conserve energy, this device can show how much all your appliances and electronic equiptment draws power while on standby mode. Be informed and stop wasting money and watts!

By Dean
Anything that uses an electronic ballast (light the compact fluorescent lights - CFLs) will not work with this device. That's because the device looks at the peak current to figure out the watts. For example, a CFL that actually uses 13 or 14 watts will erroneously show up as using 65 watts. That's because the crappy meter sees a maximum of 0.5 amps of current, but most of the time the CFL is drawing much less current. This device only refreshes about twice a second and cannot see a current that is pulsed faster than that. It will work fine for anything that uses a constant level of current, like a fan, toaster, etc. Also keep in mind that the packaging itself says it is only accurate from 125 - 1875 watts. That means anything using less that 125 watts might not show up very accurate. There are much better devices out there, like the Kill-a-Watt.

DON'T LET MY HOUSE BURN November 5, 2007
Amazon Verified Purchase
My house almost caught fire while I was on vacation.
I had too many electrical appliances on one circuit . luckily, my best bud stopped over to feed my cats & saw the house was full of smoke.
He carefully looked for the source & saw a plug smoking which burst into flame as he watched.
He unplugged the source cord, opened the windows and saved my home from burning down.
I thought the fuse on the power cord would protect me....WRONG !
With this tester I have kept the amps down to a safe level on each of my outlets.....
This tester should be in everyone's home...IT REALLY WORKS !
Very simple to use.
I give it 5 stars !
