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

This tester is quite useful and is reasonably priced. It takes a little time to master its operation so I offer the following description to help other users:I purchased the Eversame 2 in 1 USB Digital Tester which seems identical to the KJ-KjayI 2 in 1 Multifunctional Digital Multimeter Tester.When powering the tester with the type-C input, either a type-C device must be connected to the output or the micro USB adapter must be connected for the tester to function. The tester will also function when it is powered using the USB-A input regardless of the USB adapter. Even though the tester can be powered using the output connectors (according to some Youtube videos) it does not function correctly so don't do it.When first powered, the tester displays the first of several screens. All of these screens switch to the "Standby" screen (which can be changed in "settings") after one minute regardless of any load connected to the tester. Pressing the button once in "Standby" returns to the screen that was active before timing out. Clicking again advances to the next data screen. Double clicking resets the amp-hour field. Triple clicking resets the watt-hour field. Clicking four times resets the timer. Long pressing resets all three fields. All data is logged in the current test group. Data logged in a particular test group are separate from data in other test groups. There are 10 test groups that can be selected by clicking five times. The current test group will be displayed after cycling tester power.Individual data Screens:1) This display shows voltage and current on the top line using a medium font. The second line shows power and ohms (the equivalent load resistance). The third line shows watt hours, temperature, and amp hours. The last line is a timer (that only counts while powering a load for calculating time dependent values) and test group number. Click once to go to screen #2.2) On the first line, the voltage of the negative power line is shown (isn't this always zero?) followed by USB protocol in effect and the equivalent resistance of the load. The next two lines show the data line voltages and the bottom line is the voltage of the positive power line. Click once to go to screen #3.3) This display is mostly in Chinese which is the same data as screen #4.4) This screen is self explanatory.5) Large fonts without time.6) This screen graphs voltage and current with the color and range of voltage on the left with current on the right. Time resolution ranges from 0.5 to 5 seconds and is selected by long pressing. The variance of voltage and current is shown center on the bottom line.7) This screen is also a graph similar to #6 except the data lines are shown. The vertical scale is from 0 to 5 volts. I'm not sure what the two lower center voltages show but they always seem to be 1.0V. Time resolution operates the same as screen #6.8) System Settings:Long press to enter this function. Step thru the parameters by clicking once. When the desired parameter is highlighted, perform a long press until the highlighted parameter starts flashing. Clicking once decrements the parameter. Long pressing while highlighted quickly lowers the value. Double clicking increments the value. After incrementing the value, long pressing will quickly raise the value. Single click to go back lowering the value. After a few seconds of not clicking, the displayed value is saved and the tester shows "OK".There are eight system parameters:1. Over Voltage Protection (OVP) (supposedly it beeps when over this value)2. Lower Voltage Protection (LVP)3. Over Current Protection (OCP) (I think it shuts down and must be reset)4. Screen Rotation with long press (flips display 180°)5. Default Set with long press (return to factory default values)6. Clear Data with long press (clears all data in all test groups)7. Standby Style screen after timeout (either original or volts, amps, watts are displayed)8. Capacity Ratio (I guess it calculates power bank capacity as percentage)9. Exit now with long press instead of waiting for timeout9) This display starts a countdown timer to turn the display off. Click once to advance to the first display screen before the countdown finishes and turns off the display. To re-enable the display, long press which brings up reference settings. Voltage and current are displayed and I guess can be modified to calibrate these values and I'm not sure how this works but my tester seems fairly accurate as shipped.Happy testing!

I think it's really awesome to see the voltage and amperage that is coming from my USB ports. It's good to know exactly what kind of electricity my devices are getting as they get them. The only problem with this product is that I spent over 2 hours testing EVERY USB outlet in my house the day this thing came in. It was very fun. Great quality and it works very well.

<Update> Apparently, Eversame read this review, and has refunded my entire purchase price of the tester, without being asked! Believing my unit was just a one-off, I am going to purchase the same item again. Thank You Eversame for the excellent customer service! They have been upgraded a star.This review is for the Eversame 2 in 1 Type C USB Tester, AISN: B07JYVPLLJ.This is a nice little tester that has come in VERY handy since I ordered it in January, 2025. I have used it probably 4-5 times per week since then, so I feel that I have a pretty good handle on how to use it and read the information.The tester is accurate, I have crossed checked it with my FLUKE 17B. The readout always comes within 0.1vDC of the FLUKE.All the USB-A ports work beautifully. However, the USB-C Male port does not work. The female USB-C port works great. The Male port does not. There is some kind of small adapter to be inserted to “trigger the PD charging function”, but that does nothing. By the time I found this out, the exchange/return window had passed. I have had to buy a USB-C specific tester, which I’m not too pleased with.This is a great little tester for USB-A. I can’t recommend it for USB-C testing.

✅ Intro Hook:"A compact multimeter designed for USB-C devices—does it deliver reliable voltage and current readings?"✅ Performance & Features:- Voltage range: 3.6V - 30V, ensuring wide compatibility with various devices.- Current range: 0A - 5.1A, allowing precise power monitoring.- 8 LCD color screen display modes, making data easy to read and analyze.- Over-voltage and under-voltage protection, ensuring safe operation for connected devices.✅ Real-World Usage:- “Used this to test multiple chargers—accurate readings, clear display, and helpful safety features!”✅ Pros & Cons:- Pros: Compact, precise measurements, multiple display modes, safety protections.- Cons: Interface may take time to learn—button functions require familiarity.✅ Final Verdict:- “For a reliable USB-C tester that provides accurate voltage and current readings, this is a solid pick!”Does exactly what its supposed to do. Works great!

I’ve been using this tester for a few weeks and it’s been super helpful. The size is small enough to carry around, but the screen has great brightness so the numbers are easy to read. The instructions were simple, and I figured it out pretty quickly. It shows all the key features like volts, amps, and watts, which makes troubleshooting easy. I also like how it helps check power bank battery quality and charging speed on my devices. Overall, a solid little tool that does what it promises.

This is one of the things that you realize you purchase pretty much on a whim because you purchased something more expensive than you wanna make sure that you got your moneys worth overall it works pretty nice. It doesn’t heat up even when I put around 20 V through it it’s pretty good.
