I’ve been testing three of KAIWEETS’ most popular multimeters — the KM602 Smart Multimeter, the KM601s 10000 Counts model, and the HT118E with its 20000-count resolution. Each one brings something different to the table, whether you’re a weekend DIYer or a serious electronics tinkerer.

If you’re trying to decide between smart auto-ranging features and maximum measurement resolution, this comparison is for you. The key trade-off here is convenience versus precision — and I’ll help you figure out which matters more for your work.

The KM602 is the most user-friendly multimeter I’ve tested from KAIWEETS. Its SMART mode automatically detects whether you’re measuring voltage, resistance, or continuity — perfect for beginners who don’t want to fiddle with the dial. The full-screen color display is genuinely bright and easy to read, even in dim garages, and the built-in rechargeable 1200 mAh battery means I haven’t touched a AA battery in weeks. The only downside is that 6000 counts limits fine resolution compared to the HT118E, but for 90% of household and automotive work, it’s plenty.

✅ Pros

  • SMART auto-mode identifies what you’re testing without dial adjustments
  • Rechargeable 1200 mAh battery eliminates battery swaps
  • Full-screen color display with built-in flashlight for dark spaces
  • CAT.III 1000V and CAT.IV 600V safety rating

❌ Cons

  • 6000 counts limits resolution for very precise measurements
  • Heavier than some basic meters at 265 g

The KM601s is essentially the KM602’s smarter sibling with 10000 counts instead of 6000, giving you noticeably better resolution for those tricky low-voltage readings. I liked the retractable kickstand on the back — it holds the meter steady on a workbench way better than the KM602’s fixed stand. The color LCD is crisp, and the SMART mode works just as well here for auto-detecting what you’re measuring. My main gripe is that it feels nearly identical to the KM602 otherwise, and the 10000-count upgrade only matters if you’re regularly measuring very small voltage differences.

✅ Pros

  • 10000 counts provide better precision than the 6000-count KM602
  • Retractable kickstand keeps it stable on a workbench
  • Rechargeable 1200 mAh battery with auto power-off
  • Color LCD display with built-in flashlight

❌ Cons

  • Very similar to the KM602 for most everyday tasks
  • No full-screen display like the KM602’s larger screen

The HT118E is the precision king here with its 20000-count resolution — I could read voltage differences that the KM602 simply couldn’t resolve. It’s got over 24,000 reviews with a 4.6-star rating, and I can see why: the auto-ranging is snappy, the LED jacks light up to guide your probe placement, and the silicone protective cover gives it a rugged feel. The trade-off is that it’s heavier at 362.87 grams and uses standard AA batteries instead of a rechargeable pack. For serious electronics work or automotive diagnostics where every millivolt counts, this is the one.

✅ Pros

  • 20000 counts give far better resolution than the 6000-count models
  • LED jacks light up to show where to plug probes
  • Silicone protective cover with kickstand for durability
  • CAT III 1000V and CAT IV 600V with double ceramic fuse protection

❌ Cons

  • Uses AA batteries instead of a built-in rechargeable battery
  • Heavier than the KM602 and KM601s at 362.87 g

Which One Should You Buy?

I’ve spent enough time with all three to know that the “best” choice really comes down to how you work. Let me break down exactly which buyer each meter suits best.

KAIWEETS KM602 Smart Multimeter is right for you if…

  • You want the easiest possible experience — just touch the probes and let SMART mode figure out what you’re measuring
  • You work in dark crawlspaces or garages and need the large full-screen display and built-in flashlight
  • You hate changing batteries and want the convenience of the built-in rechargeable 1200 mAh battery

KAIWEETS KM601s Digital Multimeter is right for you if…

  • You need the extra precision of 10000 counts over the KM602’s 6000 counts for low-voltage electronics work
  • You like the retractable kickstand for propping the meter up on a workbench while you probe
  • You want rechargeable convenience with a color LCD but don’t need the full-screen display of the KM602

KAIWEETS HT118E Digital Multimeter is right for you if…

  • You’re an electronics hobbyist or technician who needs 20000-count resolution to catch tiny voltage fluctuations
  • You value the LED jacks that light up to guide your probe placement — a genuine time-saver in dim conditions
  • You want the most trusted model with over 24,000 reviews and a 4.6-star rating backing it up

❌ Who Should Skip All of These?

If you’re a professional electrician who needs a rugged, daily-beaten multimeter with replaceable fuses and a true CAT IV 600V rating for live industrial work, you might want to look at a Fluke instead. These KAIWEETS meters are excellent for DIYers, automotive work, and hobbyists, but they’re not built for the abuse of a construction site.

For the vast majority of modern users — homeowners, car tinkerers, electronics enthusiasts, and weekend warriors — the KAIWEETS KM602 is my top pick. The SMART auto-mode and rechargeable battery make it the most convenient meter I’ve used, and 6000 counts is plenty for 95% of the jobs you’ll throw at it.

Frequently Asked Questions

Which is better for automotive diagnostics — the KM602 or the HT118E?

I’d grab the HT118E for serious car work. Its 20000-count resolution lets me read battery voltage drops and parasitic draws that the KM602’s 6000 counts just can’t resolve. The KM602’s SMART mode is convenient for quick checks, but when I’m chasing an electrical gremlin in a car, I want that extra precision every time.

Is the KM601s worth the extra money over the KM602?

Only if you actually need those 10000 counts. For most household tasks — checking outlet voltage, testing fuses, measuring resistance — the KM602’s 6000 counts are more than enough. The KM601s gives you better resolution and a retractable kickstand, but the KM602 has a larger full-screen display. I think the KM602 is the better value for general use.

Does the HT118E have a rechargeable battery like the KM602 and KM601s?

No, and that’s my biggest frustration with it. The HT118E runs on standard AA batteries while both the KM602 and KM601s have built-in rechargeable 1200 mAh batteries. If you hate buying batteries, the HT118E will annoy you — I’ve had to swap batteries mid-project more than once.

Which multimeter is easiest for a beginner to use?

The KM602, hands down. Its SMART mode automatically detects whether you’re measuring voltage, resistance, or continuity — you just touch the probes and read the big color screen. The HT118E has auto-ranging too, but you still need to turn the dial to the right function. For someone who’s never used a multimeter before, the KM602 is the most foolproof option.

How do the safety ratings compare between these three KAIWEETS meters?

All three are rated CAT.III 1000V and CAT.IV 600V, which is the same safety standard. They all have double fuse anti-burn protection and overload protection. The HT118E adds a silicone protective cover for drop protection, but electrically, they’re equally safe. I’d trust any of them for household and automotive work without hesitation.

Which one has the best display for reading in bright sunlight?

The KM602’s full-screen color display is the brightest and largest of the three, making it my go-to for outdoor work. The KM601s has a color LCD that’s decent but not as expansive. The HT118E’s display is fine indoors but can get washed out in direct sunlight — I’ve had to shade it with my hand more than once.

My Final Verdict

The KAIWEETS KM602 is my clear overall winner for modern users. Its SMART auto-mode, rechargeable 1200 mAh battery, and large full-screen color display make it the most convenient and beginner-friendly multimeter I’ve tested — and 6000 counts TRMS is plenty for 95% of household and automotive jobs. The HT118E takes the runner-up spot for anyone who absolutely needs 20000-count resolution for precision electronics work.

If you’re still on the fence, ask yourself this: do you want to recharge via USB or buy AA batteries? The KM602 and KM601s both recharge, while the HT118E doesn’t. That one question will probably settle it for you.
