I am in no way associated with the company, I just found a good product and would like others to know. Features: you can turn off the screen, change between °C and °F, it records how much power was used, you can access multiple records of power usage, data transfer is unaffected. It reads between 3.6V to 5.4V (so far), however the screen turns black when usb-c fast charge exceeds ~6V, though it is very temporary and limits 9V to 5v usb-c. In general, the amps (blue) read between .001 to 2.8, yet to see 3+. The higher the amps are, the faster the charger. I use it to determine how much power many different chargers use, both in amperage and watt-hours of capacity. I also use it to find the best angle to place my usb solar panel, which is often straight up on a cloudy day. It is seated well in the housing, not wiggling or sliding around like my green thumb drive(hence the glue). It also comes with a usb plastic cap for the male end, and a folding plastic case, though it’s durable and I carry it without the case to save space. This is accurate, i tested it with a 22Ω+ 10Ω resistor in series to make a higher wattage 32Ω resistor, along with an ohms law calculator to compare. The meter read 32.2-32.4 ohms, which is very respectable (usb cable has a little resistance) and the other math checks out as well. I read how some have inaccurate meters, but I guess it’s been fixed since then. Overall, if you want to check how fast something charges, what voltage your charger is at(safety shut-off), how much power is consumed, and even the resistance of your charger+battery, then this is the meter for you. (Yes, that does seem kinda staged like an ad, but it is a good product) Review: Works well and as described. - This is a very nice USB tester which seems to be quite accurate. Large display that is easy to read. I like the various option available, like being able to rotate the display 180°, voltage, amps, watt hours, etc. I will probably end up ordering another. ## Features - Multi-function tester: Real-time detection of the state of charge, voltage, current, capacity, electricity, power, equivalent impedance, temperature and other indicators of electrical appliances at a glance. Measuring voltage: 3.7V-30V; measuring current: 0-4A. The tester is widely used in the quality inspection of 3C digital peripheral products, and is the first choice for digital 3C digital game enthusiasts and electronic enthusiasts - Fast charging identification, widely compatible: AT34 supports QC2.0, QC3.0, i Phone 2.4A/2.1A/1A/0.5A, Andriod DCP, fast charging protocol identification, allowing you to know the charging status of your phone anytime, anywhere - Power-off storage, data guaranteed: AT34 has a power-off storage function, which can store capacity and power data when the mobile power supply is powered off, which is convenient for subsequent viewing and facilitates the measurement of the capacity and power of the mobile power supply. Note: Other USB testers without power-down storage function cannot test capacity and power - 4-digit accuracy, more accurate measurement; measure load equivalent impedance and power; thermometer function, free switching between Celsius and Fahrenheit: using high-precision thermistor sensor; USB 3.0 interface: compatible with USB 2.0, support high current test, support USB3.0 Interface mobile hard disk and U disk test. Adopt 0.96-inch IPS high-definition color LCD screen, 160-degree wide viewing angle, high brightness and long service life - Measure the quality of the charger: connect the same load, compare no-load and load, the larger the voltage drop, the worse the charger capacity and quality; the voltage drop is not obvious or the voltage rises (leisure loss compensation function). The better the load capacity, the better the quality ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07FMQZVW2 | | Best Sellers Rank | #181,529 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #280 in Multi Testers | | Brand | MakerHawk | | Brand Name | MakerHawk | | Color | Blue | | Customer Reviews | 4.6 out of 5 stars 1,093 Reviews | | Item Dimensions | 2.52 x 0.87 x 0.47 inches | | Item Weight | 14 Grams | | Item dimensions L x W x H | 2.52 x 0.87 x 0.47 inches | | Manufacturer | MakerHawk | | Measurement Type | Ammeter, Multimeter, Voltmeter | | Minimum Operating Voltage | 3.7 Volts | | Model | 02 | | Part Number | 02 | | Power Source | Battery Powered | | Specification Met | 3c | | Style | Voltage Tester | | Style Name | Voltage Tester | | UPC | 192684493640 | | Upper Temperature Rating | 113 Degrees Fahrenheit | ## Product Details - **Brand:** MakerHawk - **Color:** Blue - **Item Weight:** 14 Grams - **Power Source:** Battery Powered - **Style:** Voltage Tester ## Images ![MakerHawk USB 3.0 Tester USB Power Meter 3.7-30V 0-4A Voltage Tester Multimeter USB Current Meter IPS Color Display Voltmeter Ammeter Charger Tester AT34 - Image 1](https://m.media-amazon.com/images/I/6185i8jFTzL.jpg) ![MakerHawk USB 3.0 Tester USB Power Meter 3.7-30V 0-4A Voltage Tester Multimeter USB Current Meter IPS Color Display Voltmeter Ammeter Charger Tester AT34 - Image 2](https://m.media-amazon.com/images/I/61awzAAH5AL.jpg) ![MakerHawk USB 3.0 Tester USB Power Meter 3.7-30V 0-4A Voltage Tester Multimeter USB Current Meter IPS Color Display Voltmeter Ammeter Charger Tester AT34 - Image 3](https://m.media-amazon.com/images/I/61wgZfwB1lL.jpg) ![MakerHawk USB 3.0 Tester USB Power Meter 3.7-30V 0-4A Voltage Tester Multimeter USB Current Meter IPS Color Display Voltmeter Ammeter Charger Tester AT34 - Image 4](https://m.media-amazon.com/images/I/61I3oWYQFeL.jpg) ![MakerHawk USB 3.0 Tester USB Power Meter 3.7-30V 0-4A Voltage Tester Multimeter USB Current Meter IPS Color Display Voltmeter Ammeter Charger Tester AT34 - Image 5](https://m.media-amazon.com/images/I/71fs4aiShgL.jpg) ## Questions & Answers **Q: What is the current consumption of the meter itself?** A: The usb meter uses about 16mA and 7mA with display off. **Q: What’s the difference between at34 and at35?** A: At34 = 4 digits total (ex : 05.01v) AT35 = 5 digits total (ex : 05.011v) There’s no real guarantee the last digits are remotely accurate. So get what’s cheap. Use it. When it burns out (like all cheap electronics) get another one. Done **Q: Does it allow data to pass while using it monitor power to a mobile phone? Like plugged a mobile phone plugged into a pc?** A: The current can be checked when the mobile phone is connected to the product while in use. **Q: Can usb data pass through? (found my existing usb power meter doesn't.)** A: Signal cables are straight through, you can use usb data. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Perfect tool to see how usb devices perform *by R***O on May 12, 2024* I received 2 of these for Christmas 5 months ago.

I like the various option available, like being able to rotate the display 180°, voltage, amps, watt hours, etc. I will probably end up ordering another. ### ⭐⭐⭐⭐ Does the job, what more do you want? *by C***S on April 30, 2019* The MakerHawk USB 3.0 Tester measures USB port direct current voltage, direct current, milliamp-hours, milliwatt-hours, and temperature in degrees Centigrade. It is simple to use: just plug in the USB device under test in one end and the Tester in the PC's USB port and the results are presented instantly on the built-in color display. Is it accurate? Probably accurate enough for most requirements. The price was low and the value was sufficient. As I said in the headline, it does the job, what more do you want? I recommend the MakerHawk USB 3.0 Tester for these reasons. ## Frequently Bought Together - MakerHawk USB 3.0 Tester, USB Power Meter, 3.7-30V 0-4A Voltage Tester Multimeter, USB Current Meter Tester, IPS Color Display Voltmeter Ammeter, USB Charger Tester AT34 - MakerHawk Type-C USB Tester Voltmeter Meter USB Multimeter Voltage and Current Tester 0-5A 4-30V USB Power Meter Multi-Function Tester Color Display Capacity Voltage Current Detector (V1) - Eversame 2 in 1 Type C USB Tester Color Screen LCD Digital Multimeter, USB C Voltage Current Voltmeter Amp Volt Ammeter Detector USB Cable Charger Indicator DC3.6-30V/0-5.1A --- ## 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.ph/products/74306174-makerhawk-usb-3-0-tester-usb-power-meter-3-7](https://www.desertcart.ph/products/74306174-makerhawk-usb-3-0-tester-usb-power-meter-3-7) --- *Product available on Desertcart Philippines* *Store origin: PH* *Last updated: 2026-05-16*
