I'm able to accomplish multiple tasks with this one kit that would normally requires multiple seperate testers! I was a little skeptical at is capability for the price but once you started getting the hang of its wonderful! Im able to test continuity, tone and trace cable, determine the length of cable and even test POE! There is a little manual that comes with it but it's not really a complicated tester. Just make sure you are using the right port on the tester to match the test you are trying to conduct! The cable toner i found to be very adequate! You do have an option to test via digital or analog settings and you can adjust the sensitivity for a solid confirmation. It does come with various adapters for different testing conditions. I was to thrilled about the case. I like the layout and the availability of storing things away but I'd prefer a hard case to house it. There have been a couple times ive had something on the toner wand driving and it would turn on and beep but if thats just a preference thing BOTTOM LINE: Highly recommend for the price! The convenience and funtionality that is packed in this kit is definetly worth this price! Review: Good value, works well. - I've had good luck with this so far and I'm pleased with the very fair price. I consider the USB-C charging (for *both* Tx and Rx units) well worth the small upgrade cost from the next model down in their line. Mine did arrive with the receiver (Rx) unit turned on and its battery stone-cold dead. But once charged, everything works as advertised. The controls are simple and intuitive and the display backlight very helpful. In my experience, tools like this typically get used in poorly lit, overcrowded closets. I can't attest to the precision of the distance test, but I know it's reasonably close at my backbone length of around 75 ft (~23m). Even a +/- 5% is very useful for troubleshooting in my setting. One word of advice: They provide a USB-C cable but you're supplying your own charger. I was unable to charge using a 'smart' charger (e.g., Anker IQ). Apparently it only wants an older-style 5V supply. In general, this is something to be aware of with a many devices on the market. I made the mistake of recharging a dive computer with the included cable connected to my own 9V-capable Samsung charger and melted the plastic housing. Not every mfr. implements the necessary circuitry for the smart chargers to correctly detect and adjust. At least in this case, connecting an inappropriate charger PREVENTED charging which might have caused some damage. As such, this is not a con. Another thing to be aware of is that it's very easy to switch between tests and forget to move your cable. There are different RJ45 jacks for different functions. I'm embarrassed to admit how many times I did this. Slow learner, apparently. ## Features - Multifunctional Tester: This Ethernet tester detects POE, network cables, and Ethernet. It is primarily used for the installation of low-voltage systems such as security monitoring, communication lines, and comprehensive cabling, reducing network cable testing and troubleshooting time for those with testing needs. - POE Test: Network rj45 tester is designed for POE switch testing and POE performance testing. Ethernet tester can automatically identify standard/non-standard POE information, including af/at voltage standards, power supply polarity, and jumper methods. The voltage test range is 0-60V. - RJ45 Tester: NF-488 network cable tester has a remote wiring function and can test for open circuits, short circuits, and crossovers in network cables. It can measure shielded wires. The large LCD backlit screen is clear and visible, and the concise display interface makes the results clear at a glance. - Power Test Function：This wire tester can test DC current, as well as the voltage, current, and power between the power supply and the electrical equipment. It also has a circuit test function that checks whether the network cable circuit connected to the switch is functioning properly. - Detailed Design：Noyafa NF-488 uses independent backlighting/shutdown timers. The casing has an anti-slip effect, and the illumination solves the problem of unclear visibility in dark areas. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B095LS8GWN | | Batteries | 1 AA batteries required.

Length function seems quite accurate and, if it shows different lengths, helps determine bad wires/connectors. Continuity test, flash test, reading POE signal, and sending a signal over a wire so I can detect it with the wand all work. Length shows pairs of wires, continuity shows each individual wire. I had space so I added a punchdown tool to my kit. Also, the buttons can press easily through the case so I added some hot glue around the power buttons. The tester works for about 5-10 minutes in sub zero temperatures. Haven't dropped it yet but it doesn't appear to have any protection against that. Tester uses 3x AAA batteries. Wand uses 9v. Would be cool if they used the same type or even cooler if they had usb charging. Still a good product, but room for improvement. ## Frequently Bought Together - NOYAFA NF-488 POE Cable Tester for Power Over Ethernet, Network Cable Continuity Checking, Switch Loop-Back POE Detector - Cable Matters 100-Pack Cat 6 Pass Through RJ45 Connectors (Cat 6 Ends / Cat6 Connector / RJ45 Modular Plugs/Ethernet Plugs/Network Connector) for Solid or Stranded UTP Ethernet Cable - RJ45 Crimp Tool Pass Through Crimper Cutter for Cat6a Cat6 Cat5 Cat5e 8P8C Modular Connector Ethernet Crimper Tool --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/340144657-nf-488-poe-cable-tester-for-power-over-ethernet-network](https://www.desertcart.pl/products/340144657-nf-488-poe-cable-tester-for-power-over-ethernet-network) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-25*
