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 | #199,243 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #296 in Multi Testers | | Brand Name | MakerHawk | | Color | Blue | | Customer Reviews | 4.6 4.6 out of 5 stars (1,095) | | Item Dimensions | 2.52 x 0.87 x 0.47 inches | | Item Weight | 14 Grams | | 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 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 ![USB 3.0 Tester Multimeter 3.7-30V 0-4A USB Voltage Tester - Image 1](https://m.media-amazon.com/images/I/6185i8jFTzL.jpg) ![USB 3.0 Tester Multimeter 3.7-30V 0-4A USB Voltage Tester - Image 2](https://m.media-amazon.com/images/I/61awzAAH5AL.jpg) ![USB 3.0 Tester Multimeter 3.7-30V 0-4A USB Voltage Tester - Image 3](https://m.media-amazon.com/images/I/61wgZfwB1lL.jpg) ![USB 3.0 Tester Multimeter 3.7-30V 0-4A USB Voltage Tester - Image 4](https://m.media-amazon.com/images/I/61I3oWYQFeL.jpg) ![USB 3.0 Tester Multimeter 3.7-30V 0-4A USB Voltage Tester - 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. ## 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.nl/products/74306174-usb-3-0-tester-multimeter-3-7-30v-0-4a](https://www.desertcart.nl/products/74306174-usb-3-0-tester-multimeter-3-7-30v-0-4a) --- *Product available on Desertcart Netherlands* *Store origin: NL* *Last updated: 2026-07-26*
