YOJOCK USB C Tester Power Meter 4-30V 0-6.5A Voltage and Current Tester Meter, USB Capacity, Temperature, Working Time Ammeter Voltmeter Power Bank Charger Detector (Classic Version)

YOJOCK USB C TESTER. Fast delivery. Securely packaged. Easily readable, uncomplicated display. I've used this for only a few days. It's shown some interesting results in the changing voltage and current levels from different chargers to sundry connected devices, so, for its performance so far, I'll give it five stars.

Love this little device. I had a lot of chargers and cables that all seemed to perform differently with different devices. With the aid of this tool, I was able to definitively ascertain and verify the capabilities of each charger and cable once and for all.

Works fine on my iPad pro showing charging at 15V 1.2A. The other meter I've got has a short USBC plug for some reason and won't connect to the charger when plugged in. Which is why I got this one.

The display is colourful and clear with a fast refresh rate. Tha accuracy of the readings are within tolerance. To change the orientation of the display for easy readings you double click the button on the outside of the body.

Nice instrument to use and gives plenty of useful information.

Looks good, does its job.

Does what it’s intended to.

Appears to work fine, but it is showing that my ipad took around 4000mah to charge, whereas the ipad reports that it received almost double the amount, same with my galaxy fold 3. Not worth the hassle of returning

Used tester, checked, verified voltages, works great, found the charging issue and now ai know what parts to order to fix devices. Works as intended.. I mean it it literally has ONE job, it was kind of a low bar to begin with but it works fine.

Viene fornito con un piccolo foglietto di istruzioni in inglese, tedesco e cinese, ma manca l'italiano. A sinistra in grande mostra Volt, Ampere e Watt, a destra il tempo di ricarica totale, i milliampere e i milliwatt totali e una freccia animata che indica la direzione di carica, tenendo premuto il tasto sul retro si azzerano i contatori. Il piccolo display ha il testo di colore bianco, ma è ben leggibile, ruota con un doppio click del bottone sul retro, con una pressione sola mostra i valori massimi raggiunti. Lo consiglio per chi ha semplici necessità per testare cavi o caricabatterie usb.

Gute Qualität und Verarbeitung, wird mit einer (schwer zu öffnenden🔒) Aufbewahrungsbox geliefert. Misst zuverlässig die Ladegeschwindigkeit und zeigt die Kapazität meiner Powerbank nach vollständiger Aufladung an. Jetzt sortiere ich die Kabel die nicht fürs Schnellladen geeignet sind aus. Für den Preis würde ich es wieder kaufen.

Does what it says it does

I use this for testing power with microcontrollers and while I cant speak to exactly how accurate it is, it does seem to be accurate enough for my use cases. I like that it shows mA/A, mV/V, mWh, mAh, and run time with a simple button to reset the timer. Really useful for getting power draw and battery run time estimates. It even shows the direction the current is going with little arrows.
