## At a glance

- Mode I is described for AC/DC voltage, resistance and diode testing, while Mode II is for wire and breaker tracing.
- Listing claims additional functions including continuity, polarity, ground, relay, fuse, trailer-light, sensor and signal-circuit checks, plus component activation.
- The 30-piece set is described as 15 back-probe pins, five banana-plug-to-alligator-clip leads, five wire-piercing probes and five alligator clips.
- Power is supplied from a vehicle battery or cigarette lighter for probe testing. The listing says the wire-tracer mode uses a 9V battery.

## Pros

- Combines circuit measurement, wire tracing and component activation functions in one automotive-focused tool.
- The included back-probe assortment is intended to access harness connectors and sensors without disconnecting every test point.
- The listing describes tone changes for locating open connections and broken wires, with wire tracing that does not require stripping insulation.

## Cons

- The listed operating scope is automotive and other low-voltage circuits, not household 220V circuits.

## Before you buy

- Listing details are inconsistent or unconfirmed: the title claims a 40ft cable while the style text says 20ft+20ft extension cable, and voltage descriptions include a 12V minimum, 12V/24V compatibility and a 6–42V DC tracer range. The included-components list names the tester, 30-piece back-probe kit and broken-wire detector, while other text refers to wire-piercing probes using a plastic case without confirming that a case is included. Check the selected listing for the exact cable, operating ranges and package contents. The manufacturer also gives conflicting warranty durations in different sections.

## In the box

- Power Probe Circuit Tester with 30-piece back-probe kit (Included)
- Broken-wire detector tool (Included)
- Case (Check selected pack): A case is referenced in the wire-piercing probe description, but it is not named in the explicit contents list.

## A good fit for

- Automotive DIYers and technicians diagnosing wiring, open circuits, voltage, resistance or components on vehicle electrical systems.
- Users who want a tester and assorted back-probing leads for connector and sensor access.

## Less suited to

- Household mains electrical work, including 220V circuits.
- Buyers who need a confirmed cable length or a clearly specified complete accessory package without checking the selected listing.

## Customer feedback

Customer feedback is generally favourable, with reported appreciation for the power-supply functions and value, including the ability to apply positive voltage or ground from the probe. Functionality feedback is mixed, with some customers saying it performs its intended tasks and others reporting that it stopped working correctly. That distinction matters for a kit intended for repeated electrical diagnosis. The favourable aggregate ratings do not resolve the reliability concern.
- Positive themes: Customers mention value for money and power-supply features.
- Positive themes: Some customer feedback describes the tool as doing what it is designed to do.
- Negative themes: Some customers report that the tester stopped working correctly.
- Mixed feedback: Functionality receives mixed feedback.

## Frequently asked questions

### What types of tests does the V200 PRO claim to support?
The listing describes AC/DC voltage, resistance and diode tests, along with wire tracing and breaker finding. It also claims continuity, polarity, ground, relay, fuse, trailer-light, sensor and signal-circuit checks, plus component activation.
### How is the tester powered?
The probe tester is described as powered by a vehicle battery or cigarette lighter. The listing says the wire-tracer mode uses one 9V battery.
### Is it suitable for household 220V circuits?
No. The listing explicitly says it is not for household 220V circuits.
### What comes in the kit?
The explicit contents list names the circuit tester with a 30-piece back-probe kit and a broken-wire detector tool. Cable length and whether a case is included are not consistently confirmed in the listing.
