Title: Crucial tool for backcountry solar users
Review: When heading out for a multi-day backcountry hike these days there’s rechargeable lights, phones/gps etc. to consider.So portable solar becomes a thing – with quoted outputs ranging from almost plausible to hilarious.There’s no magic here. Bigger panels receive more sun & produce more power but the circuitry also (seems) to be a thing.If you’ve ended up dissatisfied with a panel and bought another (and another, or more!) how do you know what they are doing for your lamp etc?So, for me at least, in steps this device. Jack in your phone, rechargeable lamp etc. to this and the other end goes into your panel – under cloudy, sunny conditions etc you then get real data about how your panel interacts with your kit and the watts it’s actually delivering.Invaluable. Recommended.

Title: Nice power indicator
Review: Good inline usb-c power indicator which when plugged in give a nice display showing the voltage, current and power (and a few other readings) of whatever you are charging.

Title: Great power monitor for a Raspberry Pi5
Review: I’m a keen experimenter with overclocking and added peripherals so was looking for a USB test meter to put in line with the PSU feeding my Raspberry Pi5. This has been absolutely perfect for the job.My only concern when ordering was the tiny font size used by the display, but it’s absolutely pin sharp with an excellent contrast ratio making the small characters very easy to read.I believe I bought this around 5 months ago, and it’s been in 24/7 use since the day it arrived without a single hiccup, and there are no signs of any display burn-in.Highly recommended.

Title: Seems accurate ..
Review: I had to buy one of these as my original tester was USB A in and out .. this enabled me to test a usb-c battery pack output.Using some A-C and C-A adapter I was able to compare accuracy with my well used/loved USB device .. showed exactly same results.

Title: Lets you see what your charger is really capable of.
Review: Does what it says on the tin – you can now test your cables and or charger to see if they are outputting what you thought they should be! Very useful bit of kit.Also usefull to see how much a battery capacity actually is if fully discharged then charged with this inline you can see how much juice it absorbed.

Title: Is it accurate??
Review: I am puzzled by this device. Being digital, it should be accurate to within 1% or so, but I get a different voltage reading compared to my older Type A USB Tester. I have checked the accuracy of my older tester against a voltmeter with accuracy +/- 0.06V at the 5V level. My older tester says 5.15V, my voltmeter says 5.13V, so I am happy that my old tester is accurate. I now connect a Samsung EP-TA50UWE charger (output 5V 1.55A) to the mains, and my old tester to the USB A port. It reads 5.15V again. I now connect the YOJOCK USB C Tester via a USB A to USB C cable, so the two testers are in series, and the YOJOCK reads 4.96V, versus 5.15V on my old, accurate, one. I then connect my Samsung Galaxy S8 phone to the YOJOCK, which now reads 4.60V, versus 5.15V which is still showing on my old tester. This is over half a volt difference – 10%. Something is wrong here.I get similar readings from several other chargers. Invariably the voltage on standard charging reads well below 5V.I ran the calibration as per the instructions as well.As a final point, it is now indicating that the phone is charging the charger….. The phone is 74% charged and is being charged. So I have no idea what is going on.I hope the seller or YOJOCK can explain this. Otherwise, I will return the item.
