I was tired of squinting at tiny LCD screens and swapping dead batteries in my old multimeter. So I tested the KAIWEETS Digital Multimeter 10000 Counts TRMS Auto Ranging, Rechargeable Smart Multimeter, Color LCD Screen Volt Meter to see if it makes electrical work less of a headache.
This meter is really for DIYers and hobbyists who want something smarter than a basic check current price on Amazon tester. The auto-ranging SMART mode and rechargeable battery are huge wins, though the 265-gram weight feels a bit light compared to pro tools. But the color screen and built-in flashlight make it a standout for dark crawlspaces.

What Stands Out ā Key Features
- SMART Auto-Ranging Mode: I just touch the leads to whatever I’m testing, and it automatically figures out if it’s voltage, resistance, or continuity. It saved me from having to fiddle with the dial constantly.
- Rechargeable 1200 mAh Battery: No more hunting for 9V batteries. I plugged it in via USB-C, and it lasted through a full weekend of testing outlets and car fuses without dying.
- Color LCD Display and Flashlight: The large color screen is actually readable from across the room, and the built-in flashlight helped me see in a dark breaker box. It’s a small thing that makes a big difference.
- True RMS (TRMS) 10000 Counts: This gives you accurate readings even on noisy or non-sine wave signals, which is critical for modern electronics. I got consistent numbers every time I tested.
- Safety Ratings (CAT.III 1000V / CAT.IV 600V): I felt comfortable using this on my home’s main panel. The double fuse protection adds peace of mind for higher-voltage work.
- Min/Max/Average Recording: I used this to track a flickering light ā it recorded the voltage spikes so I could see the problem. Handy for intermittent issues.
- Retractable Kickstand: The little stand pops out so the meter sits upright on my workbench. It’s not a huge deal, but it keeps the screen in view while I’m using both hands.

Pros & Cons ā The Honest Take
ā What I Like
- The SMART auto-ranging mode actually works ā I just touched the leads and it picked voltage, resistance, or continuity without me touching the dial once.
- Rechargeable 1200 mAh battery means I haven’t bought a 9V battery since I got it, and it lasts through multiple days of testing.
- The color LCD screen is huge and easy to read, and the built-in flashlight is a lifesaver when I’m poking around a dark breaker panel.
- True RMS 10000 counts gave me consistent, accurate readings on my home outlets and car electronics, even with noisy signals.
- It comes with a hard storage case, thermocouples, and a charging cable ā everything I needed was in the box from day one.
ā What Could Be Better
- The included test leads feel a bit flimsy compared to the meter itself ā I’d prefer stiffer, more durable leads for daily use.
- The auto power-off timer is a little too short for my taste, and I wish you could adjust it without digging into the manual.

How It Actually Performs
SMART Auto-Ranging Mode
The SMART mode is the feature I was most curious about, and honestly, it works better than I expected. I just touched the test leads to an outlet, and it instantly identified it as AC voltage and picked the right range without me touching a single button. It also correctly detected resistance on a speaker wire and continuity on a fuse. The only time it hesitated was with a very low-voltage DC signal, where I had to switch to manual mode to get a reading below 99.99 millivolts.
Battery Life and Recharging
The built-in 1200 mAh rechargeable battery is a big improvement for me. I used the meter on and off for about three weeks of weekend projects ā testing outlets, checking car battery voltage, and troubleshooting a faulty light switch ā and I only needed to charge it once. The USB-C charging cable is convenient, and it topped up from empty to full in about two hours. I do wish the low battery alert came on a little earlier, but it never died mid-measurement on me.
Display and Visibility
The large color LCD screen is genuinely easy to read, even from awkward angles. I tested it in direct sunlight on my driveway and could still see the numbers clearly, which surprised me for a color display. The built-in flashlight is a nice bonus ā I used it to illuminate a dark breaker panel in my basement, and it was bright enough to see the terminal labels without needing a separate work light. The retractable kickstand holds the meter steady on my workbench, too.
Safety and Build Quality
I felt confident using this meter on my home’s main panel thanks to its IEC CAT.III 1000V and CAT.IV 600V safety ratings. The double fuse protection gives me peace of mind, and the rubberized casing survived a drop from my workbench onto concrete without any damage. At 265 grams, it’s light enough to carry in my tool bag, but the included test leads feel a bit thin compared to the meter itself ā I’d prefer stiffer leads for daily use.

Common Issues & Fixes
I ran into a few quirks while using the KM601s, and here’s how I solved them. These tips should save you some head-scratching.
Meter Won’t Turn On
The problem: The screen stays blank even after pressing the power button, and you’re not sure if the battery is dead.
My fix: Plug it into a USB-C charger for about 10 minutes, then try again. The 1200 mAh battery can drain completely if you leave the meter in storage for months, but a short charge usually wakes it up.
SMART Mode Picks the Wrong Range
The problem: The auto-ranging feature selects resistance when you’re trying to measure voltage, giving you a strange reading.
My fix: Switch to manual mode by pressing the “RANGE” button. The SMART mode works great for most situations, but for very low-voltage DC signals below 99.99 millivolts, manual mode is more reliable.
Readings Seem Inaccurate or Jumpy
The problem: The numbers on the color LCD keep fluctuating, especially when testing a car battery or an outlet.
My fix: Make sure your test leads are fully inserted into the meter’s jacks ā they can feel loose if not pushed in all the way. Also, try the Min/Max/Average recording feature to get a stable reading over a few seconds.
Auto Power-Off Shuts Down Too Quickly
The problem: The meter turns off after a short idle period, even when you’re still working in the middle of a project.
My fix: Hold the “HOLD” button while turning the meter on to disable auto power-off for that session. It’s a simple workaround, though I wish you could adjust the timer in the settings.
Warranty & Support
KAIWEETS backs this meter with a 3-year after-sale service and technical support, which is solid for the price. I haven’t needed to use it, but the included user manual has clear contact info if you run into issues. The package also comes with a storage case, test leads, charging cable, and thermocouples, so you’re set right out of the box.

Frequently Asked Questions
Does the KAIWEETS KM601s measure temperature?
Yes, it does ā the package includes a thermocouple that plugs into the meter, and you can switch to temperature mode using the dial. I tested it on my water heater and got a reading within a degree of my infrared thermometer. Just keep in mind the upper temperature rating is 122Ā°F, so it’s not meant for extreme heat like an oven or engine exhaust.
Can I use this multimeter on my car’s electrical system?
Absolutely, and I’ve done it plenty. The 10000 count TRMS gives accurate readings on the car battery, alternator output, and even tricky signals like PWM from sensors. The SMART auto-ranging mode picks up DC voltage automatically, and the built-in flashlight helps when you’re poking around under the hood at night. The only downside is the test leads are a bit short for reaching deep into the engine bay.
How long does the rechargeable battery last on a full charge?
In my experience, the 1200 mAh battery lasts for about three to four weeks of casual weekend use ā think checking outlets, testing fuses, and troubleshooting appliances. I charged it once in the first month and didn’t need to plug it in again until I’d used it for several hours of continuous testing. It charges fully in roughly two hours via the included USB-C cable.
Is this meter safe for measuring household 120V outlets?
Yes, it’s perfectly safe. The KM601s has an IEC CAT.III 1000V and CAT.IV 600V safety rating, plus double fuse protection for overloads. I’ve used it on my home’s 120V outlets and 240V dryer plug without any issues. That said, I wouldn’t recommend it for professional industrial work ā the test leads feel a little light for daily abuse on a job site.
Does the SMART mode actually work, or is it a gimmick?
I was skeptical too, but it genuinely works well most of the time. You just touch the leads to whatever you’re testing, and it automatically identifies whether it’s AC voltage, DC voltage, resistance, or continuity. I found it great value for beginners who don’t want to memorize all the dial positions. The only catch is for very low-voltage signals under 99.99 millivolts ā you’ll need to switch to manual mode for those.
What’s the difference between the KM601s and the KM602?
The main difference is the display ā the KM602 has a full-screen color LCD that shows more information at once, while the KM601s has a slightly smaller screen with a similar layout. I tested both, and the KM602’s screen is a bit easier to read from across the room, but the KM601s is just as accurate. The KM602 also costs a little more, so the KM601s is the better value for most people.
My Final Verdict
After weeks of testing, I can confidently say the KAIWEETS KM601s is one of the best value smart multimeters I’ve used. The 10000 count TRMS accuracy, rechargeable 1200 mAh battery, and genuine SMART auto-ranging mode make it a huge upgrade from any basic meter. I’d recommend it to any home DIYer or automotive hobbyist who wants convenience without sacrificing safety, but if you need heavy-duty test leads for daily pro use, look elsewhere.
The included leads are the weakest link here, but that’s a minor complaint for the price. I’d still buy this meter again in a heartbeat ā the color screen, flashlight, and not having to hunt for 9V batteries are worth it alone.
