NOYAFA-NF-488 PoE Tester Inline Tester Power Over Ethernet Voltage Current Tester Test for POE Testing, Network Cable Continuity Checking, DC Power & Switch Loop-Back Test PoE Detector

I purchased this specifically to test a PoE switch but figured I'd be using it in the future with other PoE devices I have, or just as a cable tester in case mine fails. This arrived in perfect condition and didn't have any issues powering right up once batteries were installed. The cable continuity tester worked fine (with a good cable) and the PoE testing seemed to do the job as well - telling me the switch in question is "non-standard" (which is plenty believable) but accurately identifying the af type of a difference device, as well as power consumption through to an access point. Overall happy with this tester, especially for the cost. Hoping it lasts for a while.

Without knowing the brand and based on YouTube reviews, it's a good initial tester. The quality is good and it lives up to its claims. A good buy.

There is nothing I dislike about this product so far, but what I do like is the ease of use and the different types of testing in this one product. When working on traffic signal devices, they can be a bit delicate to surges and lightning, having the proper wiring will make all the difference between your equipment being saved or destroyed. The test that I performed was a continuity test with CAT6 shielded direct burial cable, the drain wire/ground must not be connected on the equipment side but must be connected on the supply side, as you can see in the picture it will show that my connection is correct and with one side to ground. Love this tester and I love the price, I would recommend this product.

After two DOA units, I finally got one that worked. Using the NF-488 I took all of the POE PSU's I had lying around (Ubiquiti, TP Link, etc.) and was able to determine exactly what they were, and put labels on them for future reference. POE analysis is the only thing I have used it for so far, but it works and I'm happy! It's a nice addition to my IT kit, especially since it's in a neat little zippered case.

It helps troubleshooting.

Purchased a few used Cisco switches and needed to verify POE worked, and worked correctly on all the ports. Was able to test all the ports quickly and verify they produced the correct amount of power with this.

Very easy to use and does the job of more expensive u it’s for cheap.

Tested it out and seems to be very accurate for measuring cable length and all other cable test it does. Used two different toner and both picked up the sound . One was an ideal toner and one a green line. So if you don't get the package with a toner don't fret. For a budget this is great

Haven’t tried for PEO testing, but it does a great job at testing cable continuity.

The product isn't working. I requested a return on July 29th, but no one has come to collect it so far, and I haven't received a refund either. The service is very poor.

Perfetto in tutto e per tutto. Eccellente per qualità costo.

Good tester so far, provides all info you need at a glance.

Preisleistung völlig in Ordnung.
