Test Capacity and Electric Energy of Power Bank Make sure the power bank to be tested is fully charged firstly, then connect to this USB tester and reset the capacity and electric energy by long pressing, and then fully discharge with this USB tester and 5v load till power bank run out of its energy. The reading on this USB tester is real data of capacity of your power bank. Measuring Parameters

Review: Great Diagnostic Tool for Tracking Charging Problems - Purchased this to test the USB-C ports on my Mac and phone after experiencing charging problems. The tester provides clear voltage and current readings, which made it easy to identify whether the fault was with the cable, charger, or device port. Having both USB-C and USB-A support is very helpful as it works across all my chargers. Straightforward to use and very informative. A useful diagnostic tool for anyone troubleshooting charging issues.
Review: Neat & compact tester. Comes with Micro-USB adaptor. - I did pay for this myself and it isn’t part of the desertcart Vine Program. I do have one of these under another brand but needed a 2nd one and this looked the best value at the time. These do seem to be generic, with some having a brand name on them and others don’t. As I test a lot of charger and cables, these are really great for seeing what is happening vs. the spec. Where this differs from similar products is that you can go from USB-A to USB-C and visa versa. I have another design that, if you plug one end into a USB-A port, then the other end must also be plugged into a USB-A port as well. Personally, I find that too restricting. You can change the display arrangements but some are tricky to read due to the amount of info it’s displaying, that is unless you’re up close. I tend to focus predominantly on a setting which shows me Volts, Amps and Watts at that time and ongoing. It is easy to use and the display is clear, if a bit small sometimes. You even get a Micro-USB adapter included and a simple plastic storage case. Pricing on this specific design does tend to fluctuate quite a lot depending on the brand, I paid £16.74 for this one, but have seen these (not this specific one) for £25 upwards. For the price, I thinks it is decent value and highly portable. I did run a comparison test compared to the other one I had, they are exactly the same device, and the readings were the same on both. I hope you found this review & photos interesting, informative, and useful. Thanks for reading.

## Features
