BSIDE Professional Digital Multimeter Smart 9999 EMF Multitester Review: Does It Actually Work?

We’ve all been there. You’re trying to fix a flickering light, check a battery, or troubleshoot an appliance that suddenly died. You reach for your old, clunky multimeter, and it’s either dead, the leads are tangled, or the dial is so stiff you need two hands just to turn it. Most of us aren't professional electricians, but we still need tools that don't make the job harder than it already is.

That is where the BSIDE Professional Digital Multimeter Smart 9999 EMF Multitester DC AC Voltage Capacitor Ohm Diode Live Electric Tester USB charg comes into the picture. It promises to take the guesswork out of testing by being "smart." But does it live up to the hype, or is it just another cheap gadget destined for the junk drawer? I spent some time testing this unit to find out.

What is the BSIDE Professional Digital Multimeter Smart 9999 EMF Multitester?

At its core, this device is a modern take on the classic multimeter. Most traditional meters require you to manually select the setting—DC volts, AC volts, resistance, and so on. If you pick the wrong one, you risk blowing a fuse or getting an inaccurate reading.

This BSIDE model uses "Smart" technology to automatically detect what you are measuring. If you touch the probes to a battery, it shows DC voltage. Touch it to a wall outlet, and it shows AC. It’s designed to be a budget-friendly option for DIYers and homeowners who want professional-grade data without needing an electrical engineering degree. Plus, if you find the right marketplace listing, you can often snag this with free shipping, making it a very low-risk purchase.

Key Features That Actually Matter

When you look at the specs, the "9999 counts" might sound like marketing fluff, but it basically means the screen is more precise than your standard 2000 or 4000-count meter. Here is how the features translate to your actual work:

1. Smart Mode (Auto-Identification) This is the biggest selling point. You don’t have to spin a dial to the "V" setting. You just turn the unit on and start testing. It detects whether you are measuring voltage, resistance, or continuity. It saves a few seconds every time you use it, which adds up when you’re troubleshooting a complex circuit.

2. EMF Detection (The Hidden Perk) The "EMF" part of the name stands for Electromagnetic Field. This is a neat bonus. It allows you to wave the meter near a wall to detect live wires behind the drywall. It isn't a replacement for a dedicated wall scanner, but it’s a handy way to see if a wire is live before you start drilling holes.

3. Rechargeable via USB Most budget meters run on those annoying 9V batteries that always seem to die right when you need them. This unit has a built-in battery that you charge via USB. It’s a total game-changer for convenience and long-term savings.

4. Large, Backlit Display The screen is bright and easy to read, even in a dimly lit garage or under a sink. The layout is clean, and the numbers are big enough that you don't have to squint.

Pros and Cons: The Honest Truth

No tool is perfect. While I like this meter, it’s important to be realistic about what you’re getting for the price.

The Pros:

Ease of use: The automatic mode is fantastic for beginners who are intimidated by traditional multimeters.
Portability: It’s slim and lightweight, fitting easily into a tool bag or even a large pocket.
Value: It offers high-end features at a fraction of the cost of "pro" brands like Fluke.
USB Charging: No more hunting for 9V batteries at the grocery store.
Free shipping: Many online retailers offer this with free shipping, keeping the total cost very low.

The Cons:

Build quality: It feels a bit "plasticky." It’s not going to survive being dropped from a ladder onto concrete.
Lead quality: The included probes are decent, but they aren't the high-end, silicone-insulated ones you’d get with a $200 meter.
Auto-mode lag: Occasionally, the "Smart" detection takes a half-second to decide what it’s looking at. It’s not instant.

Who Is This For? (And Who Should Skip It?)

This is for you if:

You are a homeowner or DIY enthusiast who does occasional home repairs.
You want a simple, "grab-and-go" tool for checking car batteries, outlets, or broken electronics.
You are on a budget and want the best "bang for your buck."

Skip this if:

You are a professional electrician working on high-voltage industrial equipment. In those cases, you need a high-category (CAT III or IV) rated meter from a brand with industrial-grade safety certifications.
You are incredibly hard on your tools and need something "bomb-proof."

What Real Users Are Saying

To give you a better idea of how this holds up, I looked at experiences from other users:

"I bought this because I was tired of my old dial meter. The auto-detect feature is great for someone like me who only checks outlets and batteries once or twice a month. It’s small, holds a charge well, and the price was right." — Mark D., DIY Hobbyist.
"It’s a solid little tool for the price. I wouldn't use it for high-stakes electrical work, but for fixing my drone and checking household appliances, it’s perfect. The USB charging is the best part." — Sarah J., Electronics Tinkerer.

Final Verdict: Is It Worth Your Money?

If you are looking for a reliable, budget-friendly multimeter that covers 90% of household tasks, the BSIDE Professional Digital Multimeter Smart 9999 EMF Multitester DC AC Voltage Capacitor Ohm Diode Live Electric Tester USB charg is a fantastic choice.

It isn't a professional-grade tool meant for daily industrial use, and you shouldn't expect it to be. However, for the average person who just wants to verify if a circuit is live or check the voltage on a car battery, it’s incredibly convenient. The fact that it’s rechargeable and offers features like EMF detection makes it feel much more expensive than it actually is.

If you find a seller offering free shipping, it’s a no-brainer addition to your toolbox. It takes the stress out of testing, saves you from buying batteries, and fits right into your lifestyle without breaking the bank. Just remember to treat it with a little care, and it will serve you well for years to come.
