Pros & Cons
Pros
- ✓ Reads AC/DC voltage, DC current, resistance, continuity and diode in one 2000-count meter
- ✓ Backlit 0.6-inch LCD stays readable inside breaker panels and under dashboards
- ✓ Double fuse gives anti-burn overload protection; silicone cover absorbs drops
- ✓ Data hold, auto shutoff and continuity buzzer allow true one-handed probing
- ✓ Test leads, batteries and manual all included, so nothing else to buy
Cons
- ✗ Cannot measure AC current at all, ruling out many appliance draw tests
- ✗ Will not read AC voltage below 100mV, limiting low-signal work
- ✗ 2 samples per second is slow for catching brief voltage dips
- ✗ Manual rotary switch only, so every reading needs the right range selected first
Manufacturer description
AstroAI's Digital Multimeter Tester puts 2000-count measurement in a pocket-sized tool for under a full toolbox budget. This AstroAI multimeter reads AC/DC voltage, DC current, resistance, continuity, and diode, which covers most of what goes wrong at a household outlet, a blown fuse, a dying car battery, or an automotive charging circuit. The 3 1/2-digit LCD runs 1999 counts across a 0.6-inch display with a backlight, so you can still read it under a dashboard or inside a breaker panel. Sampling runs twice per second, and polarity is shown for both negative and positive readings, so you do…
SpecPicks Verdict
SpecPicks scored AstroAI Digital Multimeter Tester 2000 Counts using a rating × review-volume × price-fit model applied to published specs and reviews across the PC & gaming hardware category. AstroAI's PC & gaming hardware lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.
Common buyer scenarios for PC & gaming hardware of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase.

Frequently Asked Questions
Can this multimeter measure AC current (amps)?
No. AstroAI states this meter cannot test AC current, and it also cannot read AC voltage below 100mV. It measures AC/DC voltage, DC current, resistance, continuity, and diode.
Is it good for testing a car battery and charging system?
Yes. AstroAI lists batteries including vehicles, automotive circuit troubleshooting, charging systems, and testing electronics in cars as intended uses, all of which run on DC voltage.
Does it come with test leads and batteries, or do I buy those separately?
Both are included. The box ships with a set of test leads, batteries, and the user manual, so the meter is usable out of the package.
Why is my multimeter showing no reading?
AstroAI cites two common causes: test lead plugs not fully seated or in the wrong sockets, and the rotary switch not set to the correct position. Check the manual before measuring.
Key Features
- Additional Tips - The following incorrect operations may cause the multimeter not to show results: Firstly, the plugs of test leads are not fully inserted or not inserted into the correct sockets. Secondly, the manual rotary switch is not placed in the correct position. In addition, this meter can not test all AC Current and below 100mV AC Voltage. Please check the user manual carefully before measurement.
- Versatile Digital Multimeter - Accurately measures AC/DC Voltage, DC Current, Resistance, and Diode. This Multimeter is a really useful tool for solving industrial and household electrical issues. Suitable for Household Outlets, Fuses, Batteries (including Vehicles), Automotive Circuit Troubleshooting, Charging Systems, Testing electronics in Cars etc.
- Troubleshooting with Accuracy - This Multimeter has a sampling speed of 2 times per second; Built-in a backlight LCD display with 3 digits (1999 count) 0.6”, and high polarity including negative and positive readings.
- Ensures Safety - Double fuse is anti-burn and protects from overloading. The silicone cover can protect the multimeter from failing damage and prevent electric shocks. And low battery indication will be displayed when battery power is low.
- Ease of Use - Support Data Hold, Auto Shutoff and Continuity Buzzer. Includes Convenient feature like LCD Backlit Screen makes it easy to use in dimly light areas. Batteries/Set of Test Leads/User Manual are Included.
