I was not expecting a lot but was quite happily surprised by the ease of use, the large number of features, and the accuracy of the voltage, current, capacitance, and resistance measurements. It is compact and has good fit and finish. It is 4000 counts meter which is fine for electronics hobbyist use. For a beginner multimeter user, an electronics hobbyist, or just to have a spare meter, this is pretty nifty. The NCV feature is handy. The set of test probes seem to be of decent quality and come with those little plastic covers that cover everything but the tips (to prevent accidental short circuits). Review: Seems Impressive for the Price - Initial testing good. While not the cheapest option available, it is still very low cost and seems like a much more professional tool than the lower-priced options I tried. This unit has a relatively compact size, but still has a decent heftiness feel to it - I do not mean that it is heavy, just that it does not feel like a 50 cent plastic toy. It comes with a decent 17 page manual written in actual English instead of some Chinese gibberish. Another notable feature is that the test leads come with tip covers that actually have real value. Instead of just completely covering the tips so that they have to be removed to use the meter at all, these leave the very ends of the tips exposed so that the leads can be used for many basic measurements with the covers left in place (such as a quick battery test). More than just convenience, these have the added value that if you need to measure something in a tight position where you are worried that the normally long and fully exposed tip might short out on something beside you intended measurement point, the lead cover proves extra protection. I'm not sure why most modern test leads come with full plastic covers anyway; what possible protection does a bare metal probe need in storage? The accuracy specs (from the manual) seem to be acceptable for a tool in this price range: DCV +-0.5%, ACV +-1.0%, Current +-1.5%, Resistance +-1.5%. While not a scientific instrument, it is very functional around the house and shop. ## Features - Wide Application - The AstroAI M4K0R Multimeter accurately measures AC/DC voltage to 600V, Current to 10A, Resistance to 40MΩ. You can use it for continuity test, diode test, battery test and live wire test. Includes 1.5V, 9V and 12V battery test modes to easily test a wide variety of batteries.

It detects LED voltage on Christmas tree lights from about 5 inches away... you may find your meter has feelings, but mine seems to not care about sensitivity.. it just indicates voltage is present. **Q: Do the Battery Test selections test under load?** A: The M4KOR model does the 1.5v - 9v - 12v battery tests each is under a small load, and does test the battery voltage as part of the DC volts ranges. The M6KOR model does NOT perform battery tests under load, but does test the battery voltage as part of the DC volts ranges. **Q: Would you choose this model or another for automotive diagnosing?** A: To answer your question I'm a master Automotive technician most of the people in the business use flukes but our use these ones because they are accurate and work just as good as the fluke when it comes to Automotive Diagnostics. There is nothing you can't do with this digital multimeter that you can do with a fluke **Q: I have been trying to measure the ac/dc amps with this but doesn't work. i wanted to know if i am missing something or its actually faulty?** A: Make sure you have the leads in the proper slots or ports for the amperage reading. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Inexpensive, works well, easy to use, accurate - very happy with this meter *by B***D on December 31, 2025* Very pleasantly surprised by this inexpensive multimeter.

This is an inexpensive multimeter that comes with a few extra features. Beyond the typical VDC, VAC, mA, Amps, Resistance and Capacitance readings, it also provides Non-Contact AC Voltage (NCV) and Live Wire AC Voltage detection. The construction is solid. The display backlighting is strong and works well. Note that the NCV detection is fidgety, though. Placing the NCV detector (located at the top of the meter) near an operational 120 VAC outlet, the meter would reliably indicate a "Low" AC voltage (green light) when it is near the outlet. However, it takes a lot of tiny meter position adjustments to get the NCV to indicate "High" AC voltage (red light) near the "hot" line of the AC outlet. The NCV operation is unreliable enough that I may just pull out the probes and plug them in. I subtracted a star from the final product rating as a result. I have included pictures of the meter's contents. The red/black meter probes come with a protective cap over the banana jacks - these will probably be lost within the first month of use. The meter probes are normally fully insulated, exposing a small sharp tip for probing circuitry. The same probes also have a removable sleeve (shown for the black probe) that can be pulled off to provide a longer "pin sticker" probe to insert into the back of Molex type connectors for readings. The 2xAAA batteries were already installed into the meter on delivery, with no protective tape to prevent electrical connection to the meter. So, I have followed the recommendations of other reviewers, and have replaced the installed cheap alkaline batteries with new Duracells just in case the original batteries may fail quickly (and possibly leak). ## Frequently Bought Together - AstroAI Multimeter Tester, TRMS 4000 Counts Volt Meter Auto-Ranging Ohmmeter Digital 1.5v/9v/12v Battery Voltage Tester Measure Voltage Current Resistance Diodes Continuity Capacitance with NCV - AstroAI 8Pcs Multimeter Test Leads Set with Alligator Clips, Plunger Test Mini Hooks and Test Probes 1000V 10A CAT III & CAT IV 600V for Fluke, KAIWEETS, INNOVA Multimeter, Voltmeter, Clamp Meter - Hard Case Replacement for AstroAI Digital Multimeter Volt Meter by Aenllosi (for 6000 Counts) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ec/products/231019063-multimeter-tester-trms-4000-counts-volt-meter-auto-ranging-ohmmeter](https://www.desertcart.ec/products/231019063-multimeter-tester-trms-4000-counts-volt-meter-auto-ranging-ohmmeter) --- *Product available on Desertcart Ecuador* *Store origin: EC* *Last updated: 2026-07-14*
