Best LCD Outlet Testers? - The Klein Tools RT250 shines 

Extremely well explained. Like that you opened one of the circuit testers to show how it works on the inside.

Good video that covers all of the points and features from cost to outlet facing angle!

I just picked up the Klein, nice to see it’s features pointed out by a pro

That was a great tip about using the tester with a blow dryer to see what kind of voltage drop a load produces at the receptacle. I recently ran power to my shed, about 40 feet from the house, and wondered how much of a drop I would get with a load more than the usual light bulb. Took the blow dryer and tester out to the shed and voltage dropped from 120 to 110 under blow dryer load. A bit more than one would like I suppose; I think in terms of 5% being a max drop. But I don't have any sensitive electronics in my shed, so I think I will be fine. I ran No. 12 wire. At the time, I looked at voltage drop tables and thought a No.10 or 8 might be better. But not being an electrician, I stayed with the No. 12 which is hard enough to work with for me. At least now I know, thanks to your video. Great job!

Extremely informative and helpful with tips. Really needed this to make an educated decision on what to get, pros cons. THANK YOU

Thanks for the reviews. I just bought the Klein, actually two of them, and I am glad I did. I enjoyed seeing the comparisons. I saw the larger one on Amazon but I am not happy with the lack of different color LED’s as well as it’s size. Even though the size is not a big issue.

Thanks for taking time to do this. Generally have used Fluke for testers, Klein and Knipex for hand tools. Busted my plug in tester, now I will get the Klein. It's a lot of tester for the money. If you have the time and money to purchase or review the Knipex self adjusting pliers, and their wrench pliers, I believe they are indispensable.

Best reviews of any products I've ever seen on Facebook.

Great idea with the 12 amp external load to test the wires. I just purchased the Klein for the gfci reading. It was nice to see the other functions.

Thank for the vid. I’ve been waiting to see one on the Klein. Waiting for it to be in store at Home Depot. Nice idea on the blow dryer,never thought of that.

The Klein tester is my favorite receptacle tester and a steal at ~$21. My only wish, like with all the basic receptacle testers, is that it had recessed holes to access the 3 connections so you could probe them with a meter. It is handy sometimes to be able to measure neutral voltage (neutral to ground).

Well put together review, sir. Thanks.

Great review, I bought the Klein Tool RT250 and it's superior to every other tester.

Great comparison! Glad I bought the Klein.

I’m interested in seeing your review of Klein Tools Digital Circuit Breaker Finder. (There are other RU-vid videos available on that subject but you’re very knowledgeable and very thorough.)

Thanks for the information, I will go with the Klein.

Fantastic video. Thank you for creating this. Definitely subscribing

Great video. Klein LCD with a 6" extension cord works for me!

Great review, thanks!

you just saved me over $250. I was contemplating the ideal circuit analyzer, but had already ordered the klein RT250 earlier today. guess I will have to pull out a calculator to figure out the percentage drop with the hair dryer, lol. as an owner of an older home with much needed wiring updates, I feel much more confident that I can get the same info from much cheaper tools. also purchased today the Klein Tools 80016 Circuit Breaker Finder Tool and the Extech CB10 to do my own side by side test of which one works better for mapping the circuits to the circuit breaker box.

Excellent review!

Great Video !!!! Perfect explanation

So educational. Thank you!

Great video. Thanks for your time.

Good review, thanks.

Another great video. Thanks.

Very helpful, thanks bud

Thank you for this review video. This Klein RT250 is worth the $20 at Home Depot.

Thanks for the video I need to buy this. It will come in handy

Excellent video! Thank you!! By the way, if you use a 3 to 2 electrical adapter and you don't use the ground tab/wire, the Klein tester will then show you an open ground as it should!

GREAT VIDEO--THANKS!!! I'M GETTING THE $20 KLIEN.

Very helpful video 👍🏻

👍👍 Great video!, thank you for posting it

Outstanding review -- very detailed. My question is: what is the acceptable voltage range for a standard 120V outlet? And, when doing the hair dryer test that you talked about, how much of a drop is too much? Either as a percentage, or actual voltage reading. Thanks a bunch. Cheers!

Great information

That Non- contact function on the Klein could save your bacon. It's easy to assume that just because the outlet doesn't work that the circuit isn't hot. I always double check with a non-contact, but sometimes those seem a little hard to trust as well.

Thanks! I’m partially color blind so the Klein is great!

Klein is a clear winner. I’ve ordered one.

GREAT VIDEO

I just bought one of these testers at Home Depot. I was really debating whether to get it since I already have a few outlet testers. This video confirmed that I made the right decision. Thanks!

I just ordered one. :)))

Solid review! Now all I need is a hair dryer;)

Great content 👌 👏 👍

I just got this testers few weeks ago, everything is fine with this testers, but I find with 2 situations that it couldn't test properly. 1. If the receptacle has no ground at the same time hot/neutral wires are reversed, the tester only detect as open ground. 2. If you test it on the outlet has no ground and a power bar with EMI filter plugged in, no matter where you test (on the 2nd outlet or on the power bar itself) it will always show hot/natural reversed, but once unplugged the power bar with EMI filter, it will change the reading to open ground.

👍 Thank you.

For the klein, they should have a "tone" option so you can hear when turning the breaker off

Thanks

Looks like a great product. It's a brand new product that's not in any local Home Depot's (Atlanta area). It's not even listed yet on the Klein website!

Thank you

Thanks for the info. I need to buy one. Question: If I need to know if there is no power on an receptacle/outlet before replacing it; if I leave this tester plug and then go to braker box and turn off braker and walk back to check outlet, will this tester will be 100% off to tell me there is no power or will stay on all the time because uses batteries? And making it useless for that purpose? Please advise.

So I already purchased the Klein RT 310 tester based on your recommendation. Does this new Klein tester provide all that functionality?

Good info, thank you.What battery does the Klein take?

I have the kaiweets socket tester ,but shows 220v for a apartment building, should be 110v, soo thinking its defective

if plug in regular outlet will it give me voltage reading

Dumb question, if you put a three prong pigtail (mini extension cord) at the end of the Klein would you still get all the voltage and correct readings?

Can the RT250 detect the dangerous ground hack when you jumper the ground to neutral on a 3 prong outlet?

Thanks for the video, but you did not show or explain how the CFCI is connected or wired.

Can you pair this with the Klein circuit Finder to locate breaker /ckt?

Do you know what will happen if you plugged the Klein tester into an outlet that had 208 or 240 or it? If someone hooked a neutral up to a separate phase.

Does the kline tell you false ground?

Will any of these detect a bootleg ground?

does the sure test by ideal indicate the time it takes for gfci to trip?

where can i buy it??

Enjoyed watching the klein plug tester video. I looked at a previous video for the klein ARC fault tester and would like to discuss some questions I had regarding Arc Faults tripping . Can you send me your contact information

Could you use a pig tail attached to any of them?

👍⚡

Recently bought one. Love the features BUT it gives me a wrong reading on open ground. Was truly disappointed.

getting the rt250 lol

How much

the klein only works with 120v

So the klein is the shit.

Neon bulbs? Uhhhhh no.
