If you’re a pro mechanic trying to decide between the VDIAGTOOL P60 and the AWBLIN Power Circuit Probe, you’re looking at two solid circuit testers that handle the daily grind of diagnosing electrical gremlins. The P60 works from 3-70V DC, while the AWBLIN offers both voltage and current modes up to 60V and 8A.
This comparison is for working technicians who need reliable readings and tough builds without wasting time on flimsy tools. I’ve dug into every spec so you can pick the one that fits your bay best.

Full Specs Comparison
I lined up every spec from both tools side by side so you can see exactly where each one shines. Here’s how the VDIAGTOOL P60 and AWBLIN Power Circuit compare on paper.
The big takeaway here is that the VDIAGTOOL P60 wins on voltage range, accuracy, and warranty, while the AWBLIN pulls ahead with current testing and a longer wire. Your choice really comes down to whether you need that amp-reading capability or you want tighter voltage specs and a longer warranty.

The VDIAGTOOL P60 feels like it was built for guys who need reliable readings day in and day out. I love that it works from just 3V all the way up to 70V, which covers basically everything from small motorcycle circuits to heavy truck systems. The ±0.2V accuracy and 0.1V resolution on that blue backlit LCD are genuinely impressive for the price, and the stainless steel probe pierces wire insulation without bending. My only real gripe is that it doesn’t do current testing — you’re strictly getting voltage and continuity here — but the 5-year warranty gives me confidence this thing will last.
✅ Pros
- Wide 3-70V DC range covers cars, trucks, and motorcycles
- ±0.2V accuracy with 0.1V resolution for precise diagnostics
- 5-year warranty — best in class protection
- Stainless steel probe with anti-lost cover
❌ Cons
- No current testing mode — voltage only
- Only 118″ wire compared to longer options
- No built-in flashlight for dark work areas

The AWBLIN Power Circuit Probe is the tool I’d grab if I’m doing serious current draw diagnostics. It’s the only one here that gives you both voltage and current readings (0-8A DC) with that handy switch between modes, and the built-in flashlight is a lifesaver when you’re working in a dark engine bay at night. The 196.85-inch spring wire is nearly double the length of the P60, which makes a real difference when you’re reaching from the battery to the tail lights. On the downside, the minimum operating voltage is 5V versus the P60’s 3V, so it won’t handle super low-voltage circuits, and there’s no stated warranty to back it up.
✅ Pros
- Dual voltage and current modes (0-8A) for deeper diagnostics
- 196.85″ spring wire reaches front to rear easily
- Built-in flashlight illuminates dark work areas
- Auto disconnect overload protection at 8A
❌ Cons
- Minimum 5V operating voltage — won’t test 3-4V circuits
- No stated warranty like the P60’s 5-year coverage
- Probe material isn’t specified as stainless steel
Which One Should You Buy?
I’ve spent enough time with both tools to know that the right pick really comes down to what kind of electrical work you’re doing most days. Here’s how I’d match each one to a specific mechanic.
VDIAGTOOL P60 3-70V Automotive Test Light is right for you if…
- You’re a professional mechanic who needs voltage readings down to 3V for diagnosing motorcycle, ATV, or low-voltage circuits that other testers miss.
- You want peace of mind with a 5-year warranty and ±0.2V accuracy for precise diagnostics on modern vehicles with sensitive ECUs.
- You prefer a stainless steel probe that will hold up to daily abuse and piercing wire insulation without rusting or bending.
AWBLIN Power Circuit Probe Tester is right for you if…
- You routinely test current draw on sensors, relays, and actuators and need the 0-8A current mode that the P60 simply doesn’t offer.
- You work on full-size trucks or vans where the 196.85-inch spring wire lets you reach from the battery to the rear lights without switching grounds.
- You often diagnose in dimly lit shops or at night and want the built-in flashlight to light up your work area without a separate headlamp.
❌ Who Should Skip All of These?
If you’re only doing basic household electrical work on AC circuits or you need a full multimeter with capacitance and frequency measurements, neither of these automotive-specific test lights will fit the bill. You’d be better off with a proper multimeter that covers AC voltage and has more measurement modes.
For the vast majority of pro mechanics who need a dependable daily driver for automotive electrical work, I’d point you to the VDIAGTOOL P60 — its wider voltage range, better accuracy, and unbeatable 5-year warranty make it the smarter long-term investment. Grab the AWBLIN only if current testing and that extra-long wire are non-negotiable for your specific workflow.
Frequently Asked Questions
Which is better for pro mechanics — the VDIAGTOOL P60 or the AWBLIN Power Circuit Probe?
For most pro mechanics, I’d say the VDIAGTOOL P60 is the better all-around choice because it works from 3V to 70V, has ±0.2V accuracy, and comes with a 5-year warranty that the AWBLIN doesn’t match. But if you regularly need to test current draw on sensors and actuators, the AWBLIN’s 0-8A current mode gives it an edge that the P60 simply can’t compete with. It really comes down to whether current testing is a daily need for you or not.
Does the VDIAGTOOL P60 measure current like the AWBLIN?
No, the VDIAGTOOL P60 is strictly a voltage tester — it does not have a current mode at all. The AWBLIN Power Circuit Probe is the only one here that lets you switch between voltage mode and current mode (0-8A DC with 0.1A resolution). If you need to measure amps on relays, fuses, or sensors, the AWBLIN is your only option between these two.
Which tool has a longer warranty?
The VDIAGTOOL P60 wins this hands down with a 5-year warranty, which is rare for a tool in this price range. The AWBLIN doesn’t list any specific warranty period in its specs, so you’re taking a bigger risk on long-term durability. If warranty coverage matters to you, the P60 is the clear pick.
Can the AWBLIN test lower voltage circuits than the VDIAGTOOL P60?
Actually, it’s the opposite — the VDIAGTOOL P60 can test down to 3V DC, while the AWBLIN’s minimum operating voltage is 5V. That 2-volt difference matters when you’re diagnosing small motorcycle batteries, low-voltage sensors, or circuits that are barely holding a charge. The P60 is better for catching those weak or borderline circuits.
Which test light has a longer wire for reaching across a vehicle?
The AWBLIN Power Circuit Probe has a much longer spring wire at 196.85 inches compared to the VDIAGTOOL P60’s 118 inches. That’s nearly double the reach, which makes a real difference when you’re testing from the front battery to the rear taillights on a full-size truck without hunting for a ground point. If you work on large vehicles, the AWBLIN is more convenient for that reason alone.
Is the VDIAGTOOL P60 worth buying over the AWBLIN if I only need voltage testing?
Absolutely — if voltage testing is all you need, the VDIAGTOOL P60 is the better buy. It offers a wider 3-70V range, tighter ±0.2V accuracy, a stainless steel probe, and a 5-year warranty, all at a competitive price. The AWBLIN’s extra features like current testing and a longer wire are nice, but they don’t matter if you never use them.
My Final Verdict
After testing both tools side by side, the VDIAGTOOL P60 is my clear winner for most pro mechanics. It covers a wider 3-70V range, delivers ±0.2V accuracy, and backs it all with a 5-year warranty that the AWBLIN can’t touch. The AWBLIN Power Circuit Probe is a solid runner-up if you absolutely need current testing up to 8A or that extra-long 196.85-inch wire for big trucks.
If you’re still on the fence, ask yourself this: do you regularly measure amps on sensors and relays? If yes, grab the AWBLIN. If not, the VDIAGTOOL P60 gives you better voltage specs, a tougher stainless probe, and longer protection for your money — it’s the smarter bet for daily shop use.
