If you’re new to electrical work, picking between the ANENG SZ02 and the ANENG 620C can feel overwhelming. Both are smart auto-ranging meters, but the SZ02 offers a higher 9999-count TRMS display while the 620C uses a 6000-count system with a built-in rechargeable battery.
I’ve dug through the specs for both so you can decide which one fits your toolkit without wasting money. The real trade-off here is raw measurement range versus modern convenience like USB-C charging. Keep reading because I’ll break down exactly who should grab which model.

Individual Product Breakdown
I spent time digging through the specs and customer feedback for both meters to see which one actually delivers for someone just starting out. Here’s my honest take on each.

The SZ02 is the one I’d hand to a beginner without hesitation. The 9999-count TRMS display gives you more decimal places than the 620C, which really helps when you’re testing sensitive electronics or car circuits. I love that it comes with a temperature line and dual torch lighting — that’s a lot of extras for a pocket-sized meter. The only downside is that it runs on 2 AAA batteries, so you’ll need to keep spares around instead of just plugging in a cable.
✅ Pros
- Higher 9999-count TRMS accuracy for finer readings
- Includes temperature probe and dual torch for dark workspaces
- Double ceramic fuse anti-burn protection for safety
- Comes with a full accessory kit including alligator clips and puncture needles
❌ Cons
- Requires AAA batteries — no rechargeable option
- Slightly bulkier than the 620C due to extra accessories

The 620C is the modern pick thanks to its built-in rechargeable battery and Type-C charging cable — no hunting for AAA batteries ever again. At just 100 grams, it’s noticeably lighter and easier to pocket than the SZ02, which makes it great for quick jobs around the house. The 6000-count display is plenty for basic DIY work, and the smart mode automatically detects what you’re measuring. My main gripe is that it lacks the temperature probe and the higher resolution of the SZ02, so it’s less versatile for more advanced troubleshooting.
✅ Pros
- Rechargeable battery with Type-C cable — no battery replacements
- Ultra-light at 100g with compact 3.94 x 1.97 x 1.97 inch size
- Smart mode auto-detects measurements for easy one-handed use
- Double insulation and overload protection for safe handling
❌ Cons
- Lower 6000-count resolution limits precision on sensitive circuits
- No temperature probe included in the package
- Fewer accessories — just test lead, temp probe, and charging cable
Which One Should You Buy?
I’ve tested the specs on both meters, and honestly, neither is a bad choice — it just comes down to what you value more. Let me match you with the right one based on your situation.
ANENG SZ02 is right for you if…
- You’re troubleshooting car electronics or sensitive circuits where the 9999-count TRMS resolution actually matters.
- You work in dim garages or basements and need the dual torch lighting plus LCD backlit screen.
- You want the full accessory kit with temperature probe, alligator clips, and puncture needles right out of the box.
ANENG 620C is right for you if…
- You hate buying batteries and want the rechargeable Type-C setup that’s always ready to go.
- You need something ultra-portable at just 100g that disappears into your pocket for quick DIY checks.
- You’re a total beginner who wants smart mode to auto-detect measurements without fiddling with dials.
❌ Who Should Skip All of These?
If you’re doing professional electrical work that requires CAT IV safety ratings or high-voltage industrial testing, skip both of these. You’d be better served by a bench-grade meter from Fluke or Klein that offers certified safety ratings and higher accuracy specs.
For the typical beginner just fixing outlets, checking car batteries, or testing household wiring, I’d point you to the ANENG SZ02 — that extra 9999-count resolution plus the temperature probe makes it the better long-term investment for learning.
Frequently Asked Questions
Which is better for a beginner: the ANENG SZ02 or the ANENG 620C?
I’d give the edge to the ANENG SZ02 for most beginners because the 9999-count TRMS display gives you more precision than the 620C’s 6000-count readout. That extra resolution matters when you’re learning to diagnose voltage drops or test sensitive electronics. The SZ02 also includes a temperature probe and dual torch lighting, which are nice extras for the same price range. If you absolutely hate dealing with batteries, though, the 620C’s rechargeable Type-C setup is a compelling reason to go the other way.
Is the ANENG SZ02 worth the extra cost over the ANENG 620C?
They’re priced nearly identically, so I wouldn’t say you’re paying a premium for the SZ02 — it’s more about what you get for the same money. The SZ02 packs in a temperature probe, alligator clips, puncture needles, and a storage bag, while the 620C keeps it lean with just the essentials. For that reason, I think the SZ02 delivers more value per dollar for a beginner who wants to experiment with different test setups.
Which multimeter has better battery life: the SZ02 or the 620C?
The ANENG 620C wins this one hands down because it has a built-in rechargeable battery with a Type-C charging cable — you never have to buy replacements. The SZ02 relies on 2 AAA batteries that are pre-installed, which is convenient at first but means you’ll need spares eventually. Both have auto-sleep features to conserve power when idle, but the 620C’s rechargeable design is the more modern approach for long-term use.
Can both the SZ02 and 620C measure temperature?
Yes, both can measure temperature, but the ANENG SZ02 includes the temperature probe right in the box while the 620C also lists temperature as a function and includes a temperature probe in its accessory kit. So you’re covered either way. Just know that the SZ02’s package is a bit more generous overall with its extra test leads and connectors.
Which multimeter is safer for a first-time user?
Both meters are built with safety in mind, but I feel slightly more confident recommending the ANENG SZ02 because of its double ceramic fuse anti-burn protection. The 620C has double insulation and overload protection, which is solid too, but the SZ02’s fuse system adds an extra layer of defense against accidental overloads. If you’re brand new to electrical work, that extra protection is worth having.
Which is more portable: the SZ02 or the 620C?
The ANENG 620C is the more portable option at just 100 grams and dimensions of 3.94 x 1.97 x 1.97 inches — it genuinely disappears into a pocket. The SZ02 is also compact and palm-sized, but it comes with a larger accessory kit that adds bulk to carry around. If you’re tossing a meter in a toolbox or backpack for quick jobs, the 620C’s lighter build is the way to go.
My Final Verdict
After weighing everything, the ANENG SZ02 is my clear winner for beginners. The 9999-count TRMS display gives you noticeably better precision than the 620C’s 6000 counts, plus the included temperature probe and dual torch lighting make it a more complete package for learning. The 620C is still a solid runner-up for anyone who prioritizes the rechargeable Type-C battery and ultra-light 100g build above all else.
If you’re still on the fence, think about this: both meters cost about the same, but the SZ02 simply gives you more tools to grow into. You’ll thank yourself later when you need that extra resolution for car circuits or want to test temperatures without buying an add-on probe.
