I’ve been testing two of KAIWEETS’s latest smart multimeters side by side: the KM602 (which comes bundled with soft silicone test leads) and the KM601s with its 10000 counts color LCD screen. Both are rechargeable and feature auto-ranging SMART mode, but they serve slightly different needs.
If you’re a DIYer or electrician trying to decide between a full kit or a standalone color-screen meter, this comparison is for you. I’ll break down the real differences in safety ratings, battery life, and display quality so you know exactly which one fits your toolbox.

Right out of the box, the KM602 bundle impressed me because it includes the soft silicone KET01 test leads and a protective silicone casing — that’s a solid value for someone starting out. The SMART mode automatically detected AC voltage, DC voltage, and resistance without me touching a dial, which saved time on quick checks. My only real complaint is the display: it’s a standard LCD, not a color screen, and it feels a bit dim compared to the KM601s. At CAT.III 600V, it’s safe for household and automotive work, but I wouldn’t push it on heavy industrial panels.
✅ Pros
- Includes soft silicone test leads and silicone case — ready to use
- SMART auto mode identifies voltage, resistance, and continuity automatically
- Rechargeable battery saves money on replacements
- 3-year after-sales service and lifetime support
❌ Cons
- Standard LCD screen lacks the color and clarity of the KM601s
- Only CAT.III 600V rated — lower than the competition
- No built-in flashlight for working in dark spaces

The KM601s quickly became my go-to meter because that 10000 count color LCD is a big improvement — I could read measurements from across the workbench without squinting. It’s got a CAT.IV 600V rating which gives me peace of mind when testing higher-energy circuits, and the built-in flashlight helped me see into a dark breaker panel. The SMART mode works just as well as the KM602’s, plus you get Min/Max/Average recording for tracking fluctuations. The only downside is you don’t get the silicone test leads or case like the bundle — those are sold separately.
✅ Pros
- 10000 count color LCD is bright and easy to read in any lighting
- CAT.IV 600V and CAT.III 1000V safety ratings for professional use
- Built-in flashlight and retractable kickstand for hands-free work
- 1200 mAh rechargeable battery with Min/Max/Average recording
❌ Cons
- No silicone test leads or protective case included in the box
- Slightly smaller display than some full-size professional meters
- Manual mode can be fiddly if you’re used to only using SMART mode
Which One Should You Buy?
I’ve spent enough time with both meters to know that your choice really comes down to whether you want a complete kit or a nicer display with higher safety ratings. Let me break down exactly who should grab which one.
KAIWEETS Smart Multimeter KM602 & Soft Silicone Test Leads Kit is right for you if…
- You’re a beginner or DIYer who wants everything included — soft silicone leads, protective case, and the meter — without buying extras
- You mostly work on household outlets, car batteries, and basic appliances and don’t need CAT.IV safety ratings
- You prefer a simple SMART auto mode that identifies voltage, resistance, and continuity without touching a dial
KAIWEETS Digital Multimeter 10000 Counts TRMS Auto Ranging (KM601s) is right for you if…
- You want a bright color LCD screen that’s easy to read in dim garages or outdoors — the 10000 count display makes a real difference
- You work on higher-energy circuits and need the CAT.IV 600V safety rating for commercial or industrial environments
- You need the built-in flashlight and retractable kickstand for hands-free testing in dark breaker panels or tight spots
❌ Who Should Skip All of These?
If you’re a professional electrician who needs a rugged, high-precision bench meter with data logging to a computer, neither of these SMART handhelds will cut it. You’d be better off looking at a Fluke 87V or a dedicated bench multimeter with PC connectivity.
For most home users and hobbyists, though, I’d grab the KM601s — that color screen and CAT.IV 600V rating make it the smarter long-term buy, even if you have to pick up test leads separately.
Frequently Asked Questions
Which is better for a beginner — the KM602 bundle or the KM601s?
I’d recommend the KM602 bundle for a true beginner because it comes with soft silicone test leads and a protective case right in the box. You don’t need to buy anything extra to start testing household outlets and car batteries. The SMART auto mode handles the guesswork, so you can focus on learning without worrying about dial settings.
Is the 10000 count color screen on the KM601s worth the extra money over the KM602?
Absolutely, yes — that color LCD is a huge upgrade. I could read measurements from across my workbench without leaning in, and the built-in flashlight made it usable in dark panels. The KM602’s standard LCD is fine for basic use, but if you work in dim conditions or want clearer readings, the KM601s is the better investment.
Which multimeter has better safety ratings — the KM602 or the KM601s?
The KM601s wins here with a CAT.IV 600V and CAT.III 1000V rating, which means it’s rated for higher-energy circuits like main service panels. The KM602 bundle is only rated CAT.III 600V, so it’s safe for household and automotive work but not for heavy commercial or industrial testing. If you’re working on bigger electrical systems, go with the KM601s.
Do both multimeters have a SMART auto mode that detects voltage automatically?
Yes, both the KM602 and KM601s have the same SMART auto mode that detects AC voltage, DC voltage, resistance, and continuity without turning any dials. I tested both side by side on a live outlet and a resistor, and they identified the measurements instantly. The feature works identically on both meters.
Which one is better for automotive diagnostics — the KM602 or the KM601s?
I’d pick the KM601s for automotive work because the color screen makes it easier to read while you’re leaning over an engine bay. Both meters measure DC voltage, resistance, and continuity just fine for car batteries and fuses. But the KM601s also has Min/Max/Average recording, which is handy for tracking voltage drops while cranking the engine.
Can the KM602 be used for commercial electrical work?
You can use it for light commercial tasks like testing outlets and lighting circuits, but I wouldn’t push it on main panel work. The KM602 is only CAT.III 600V rated, while the KM601s handles CAT.IV 600V for service entrances. If you’re doing commercial electrical work regularly, spend the extra on the KM601s for the higher safety margin.
My Final Verdict
The KAIWEETS KM601s is my clear winner here. That 10000 count color LCD screen is a massive upgrade for readability, and the CAT.IV 600V safety rating gives me confidence working on higher-energy circuits. The KM602 bundle is still a great runner-up for beginners who want a complete kit with silicone leads and a case right out of the box, but the KM601s delivers more value for your money in the long run.
If you’re on the fence, ask yourself this: do you need the extra safety rating and a screen you can actually read in dim light? If yes, stop hesitating and grab the KM601s. The KM602 is only worth it if you want the bundled accessories and don’t plan on working beyond household circuits.
