Handy tool that combines multiple tools into one, battery clamps are a bit weak
Reviewed in Canada on October 10, 2024
�鶹�� Vine Customer Review of Free Product( What's this? )
I wanted the JDIAG power circuit probe tester to eliminate the need to carry multiple testers in my vehicle for trouble shooting. When it comes to working on cars/trailers based on 12V DC, this will replace a multimeter/continuity tester and a probe type circuit tester. In addition, you can use this to check 12V components to see if they are working by supplying power at a current of up to 8 amps to the components. This is an easy way to test bulbs, especially LEDs or relays. You can also use this as a long jumper to bypass suspected faulty components such as switches (the black clamp and auxiliary ground are tied together in the tester (the manual does warn you that there is no overload protection when used this way).

Recently I had a bad taillight on a small utility trailer. With this I was able to quickly eliminate the bulb as being the issue, see that the voltage on the positive side was good, and identify that there was a bad ground at that light (ground at trailer connection was good).

The only issue with this is the clamps are a bit weak. There is not a lot for the clamp to grab on to in the vehicle I had the trailer hooked up to, especially on the positive terminal and a couple of times the weight of wiring caused the clamp to slip off. I may end up putting clamps on with a stronger spring. That will be easy with the long wires to the clamps and won't affect the reach much. This tester is also convenient to test components on a test bench by pairing it with a small 12V rechargeable battery (I am using a 5ah LiFePO4 battery to do this).

The manual that comes with this is not written very well. If you understand 12V circuitry, the illustrations are more useful than the text. If you are new to troubleshooting 12V DC issues, you might need a little extra information that can be found online, especially in relation to tracking down a short circuit (main symptom of this will be blown fuses).

This is a decent dedicated 12V DC testing tool with a couple of advantages over a circuit tester and multimeter. At time of writing this review, there is a 20% discount coupon available adding a little more value for money spent. While you could purchase a probe circuit tester and multimeter at a lower cost, it would not have the additional functionality of component testing (that can be done with both pos and neg voltage) or acting as a jumper. That is also 2 tools you have to keep track of, and in the case of the multimeter, make sure the battery in it was good. This tool does not need any internal battery to function which is nice. I do wish it came with some sort of case. Even a soft nylon bag would be useful.

Will not output 8A at a full 12V
Reviewed in Canada on December 2, 2024
�鶹�� Vine Customer Review of Free Product( What's this? )
The probe beeps when it touches a ground and it displays 0V. This makes the difference with no beep and 0V displayed when nothing is connected. For 12V there's no beep, since it obvious that there's something connected.

The tool has the ability of providing ground or 12V when pressing the button down or up. But the wires are too thin. They are only 22AWG. It causes a problem when powering the device under test.

With 12V on the input, the probe is only able to provide these voltages on its output. I did all the following voltage measurements using a lab power supply and an electronic load:
At 1A of load, the output voltage drops to 11.4V.
At 2A of load, the output voltage drops to 10.8V.
At 3A of load, the output voltage drops to 10.2V.
At 4A of load, the output voltage drops to 9.8V.
At 5A of load, the output voltage drops to 9.3V.
At 6A of load, the output voltage drops to 8.7V.
At 7A of load, the output voltage drops to 8.1V.
At 8A of load, the output voltage drops to 7.6V.

With the majority of the devices that you want to test being a few amps or more, this Power Probe clone fails to deliver the basic functionality.

for basic features it performed well enough
Reviewed in Canada on October 24, 2024
�鶹�� Vine Customer Review of Free Product( What's this? )
There is value in having a tool like this for some basic automotive 12V DC testing and having the ability to induce 12V positive current (low amperage under 8 Amps) via the switch can prove useful when used correctly. Wiring seems thin and connections at thin/flimsy clamps give me the impression it may not stand up to the test of time. Same goes for the construction, plastic body does not feel robust so I would want to drop it too many times or drag it by the cord. For basic functionality when used correctly, it does work and can help to make quick work of what can otherwise be a problem to diagnose or trace. The tool's long probe proved versatile to fit in where you need to get into with minimal disassembly for access and the projected light at the tip worked satisfactory with digging up behind the dash or under the seat. Overall it is a good tool to perform basic circuit checks, validate circuit function by triggering a ground or power as needed and eliminate the need to have separate test light and voltmeter on hand in certain applications. The tell tale red or green polarity indicators are a little small, other professional level tools of this sort will illuminate the entire display in colour to represent polarity or beep when selector switch is depressed, so this tool is pretty basic without bells & whistles.

Works pretty well for low current circuits. Is a bit flimsy and cheaply made compared to the name brand circuit testers I have used in the past.
Will get the job done however, for a bit less money.

The JDIAG PB10 Probe Tester is a multi-function tool that can be helpful for diagnosing electrical issues in vehicles. I used it recently to check the voltage at the fuel pump and confirm it was receiving power. (Rusty old truck, and it helped me track down a bad ground.) The tester is easy to use and the LED screen is bright and clear. However, the included instructions could be more detailed for some of the advanced functions.

Handy for diagnosing electrical issues
Reviewed in the United States on December 21, 2024
�鶹�� Vine Customer Review of Free Product( What's this? )
This is a handy probe for diagnosing electrical issues with your vehicles.

I used it on my golf cart to find a wiring fault and to find a suitable circuit in my car to install a dashcam.

It's pretty simple to use ... I wish it came with a carrying case, because there is a bundle of wires and stuff and just keeping it in your tool bag is impractical. Really needs a carrying case.

Otherwise, it's a pretty good probe.
