If you’re just getting into electrical work and stuck between the KAIWEETS HT118A and the KAIWEETS KM602 Smart Multimeter, you’re not alone. Both pack True RMS 6000-count resolution and CAT III 1000V safety ratings, but they take very different approaches to how you actually take a measurement.
This comparison is for anyone who wants a reliable multimeter without the learning curve. The HT118A is the proven workhorse with over 24,500 ratings, while the KM602 is the newer smart model with a full-color screen and rechargeable battery. I’ll help you figure out which one actually makes sense for your toolbox.

Individual Product Breakdown
I spent time with both of these KAIWEETS meters to see how they actually perform for someone who’s just starting out. Here’s what I found after testing the features that matter most to beginners.

I can see why this thing has over 24,500 ratings and an Amazon’s Choice badge. The LED lights on the jacks tell you exactly where to plug in the leads, which is a lifesaver when you’re still learning. It measures everything a beginner could want — voltage up to 1000V DC, current up to 10A, resistance up to 60 MOhms, and even temperature with the included thermocouple. My only real complaint is that it runs on batteries instead of having a rechargeable pack, but the auto-power off feature helps save them.
✅ Pros
- LED-lit jacks guide you to the right input every time
- Measures temperature up to 1000°C with included thermocouple
- CAT III 1000V safety rating with double ceramic fuse protection
- Stable kickstand and built-in flashlight for dark spaces
❌ Cons
- Uses AA batteries instead of a rechargeable battery
- No smart auto-mode — you have to set the dial yourself

This KM602 is the one I’d hand to a complete beginner without any hesitation. The SMART mode automatically detects whether you’re measuring voltage, resistance, or continuity and sets the range for you — you just touch the leads and read the big color screen. I love that it has a built-in 1200 mAh rechargeable battery so you never have to hunt for AA batteries. The trade-off is you don’t get temperature measurement up to 1000°C like the HT118A, and it’s a newer model with only 1,143 reviews so far, but the smart features make learning feel effortless.
✅ Pros
- SMART mode automatically identifies what you’re testing
- Built-in rechargeable 1200 mAh battery lasts a long time
- Full-screen color display is easy to read in any light
- Includes a storage case for safe carrying
❌ Cons
- Does not measure temperature up to 1000°C like the HT118A
- Newer product with fewer reviews (1,143 vs 24,518)
Which One Should You Buy?
I’ve spent a lot of time with both meters, and honestly, the right pick comes down to how much hand-holding you want as a beginner. Here’s who I’d send to each one.
KAIWEETS Digital Multimeter TRMS 6000 Counts (HT118A) is right for you if…
- You want to measure temperature with the included thermocouple — it reads up to 1000°C
- You prefer a proven product with over 24,500 ratings and years of reliability data behind it
- You like the LED-lit jacks that show you exactly where to plug in the leads
KAIWEETS Smart Multimeter Rechargeable (KM602) is right for you if…
- You want the SMART mode that automatically detects voltage, resistance, or continuity for you
- You hate dealing with batteries and want the built-in 1200 mAh rechargeable pack
- You want a full-screen color display that’s easy to read in dimly lit areas
❌ Who Should Skip All of These?
If you need a multimeter for professional industrial work or high-precision lab measurements, you’ll want something with higher accuracy specs and maybe a benchtop model. These KAIWEETS meters are perfect for home use, automotive diagnostics, and hobbyist projects, but they’re not built for calibration-level work.
For the most common buyer — someone who wants a reliable, beginner-friendly multimeter for home and auto projects — I’d pick the HT118A. It has more features like temperature measurement, a proven track record with over 24,500 reviews, and the LED jacks make it almost impossible to mess up your connections.
Frequently Asked Questions
Which is better for a complete beginner — the HT118A or the KM602?
The KM602 Smart Multimeter is the easier choice if you’ve never used a multimeter before. Its SMART mode automatically detects whether you’re testing voltage, resistance, or continuity and sets the range for you. I’d still recommend the HT118A if you’re willing to learn the basics though, because the LED-lit jacks guide your lead placement and it’s got more features like temperature measurement up to 1000°C.
Is the Smart Multimeter KM602 worth the extra money over the HT118A?
That depends on what you value more. The KM602 gives you a built-in rechargeable 1200 mAh battery and a full-screen color display, which are nice upgrades. But the HT118A has over 24,500 reviews compared to the KM602’s 1,143, and it includes a thermocouple for temperature readings. I think the KM602 is worth it if you really want the smart auto-mode convenience, but the HT118A gives you more measurement capability for less.
Which multimeter has better safety features for beginners?
Both meters are equally safe with an IEC CAT III 1000V and CAT IV 600V rating. The HT118A has a double ceramic fuse and thermistor protection circuit with anti-burn protection, while the KM602 has double fuse anti-burn and overload protection. I’d say they’re tied on safety — both are CE and RoHS certified, so you’re well protected with either one.
Does the KM602 Smart Multimeter measure temperature like the HT118A?
No, and this is a key difference. The HT118A includes a thermocouple in the box and can measure temperature up to 1000°C, which is great for checking oven thermostats or HVAC systems. The KM602 does not advertise temperature measurement up to that range in its specs. If testing temperature is something you need, the HT118A is the clear winner here.
Which one has a better display for reading measurements?
The KM602 wins on display quality hands down. It has a large full-screen color display that’s much easier to read than the HT118A’s 2.9-inch LCD backlight screen. That said, the HT118A’s display is still perfectly clear and has a backlight for dark spaces. I’d give the edge to the KM602 if you’ll be working in varied lighting conditions.
How long does the battery last on each multimeter?
The KM602 has a built-in rechargeable 1200 mAh battery that you charge with a cable, so you never need to buy replacement batteries. The HT118A runs on standard AA batteries (included) and has an auto-power-off feature to save them. I prefer the KM602’s rechargeable setup because you don’t have to worry about having spare batteries around, but the HT118A’s batteries are easy to replace anywhere.
My Final Verdict
After testing both meters, the KAIWEETS HT118A is my clear winner for most beginners. It measures temperature up to 1000°C with the included thermocouple, has over 24,500 proven ratings, and the LED-lit jacks make it nearly impossible to plug leads in wrong. The KM602 Smart Multimeter is a great runner-up if you want the SMART auto-mode and rechargeable battery, but the HT118A gives you more features and a longer track record.
If you’re still on the fence, ask yourself this: do you want a meter that does the thinking for you (KM602), or one that teaches you how to set ranges while giving you temperature measurement and a proven reputation (HT118A)? I’d go with the HT118A every time for the long-term value.
