FNIRSI USB Testers
FNIRSI-FNB48P Ammeter Voltmeter USB Tester TYPE-C Fast Charge Detection Trigger Capacity Ripple Measurement with CNC Metal Shell
Questions and Answers
Can it connect to the PC via Bluetooth? Gives more mobility.
To perform its function it needs to be connected to the power source that you measure, if it is the USB port of the PC, it must be connected to the PC, but if you measure a different source, you can connect the tester via Bluetooth to the PC and follow the readings there.
What is the difference from FNB48S and this? Except the finish of the outer shell Ofcourse? Or will I get the same functionality from FNB48S?
According to FNIRSI Support it has the same functionality. But it needs its own Firmware (FNB48 has its own Firmware, FNB48S has its own Firmware and FNB48P has its own Firmware) so I think there are technical differences between those models in used chips and Display or some other parts. People say FNB48S has better Ripple Curve than FNB48.

So far the best universal USB meter that I own is also equipped with an oscilloscope for measuring ripple, I recommend it

This is a really handy unit to have. I already had a nice USB tester. However the ability to fully evaluate all the different modes on a PD or QC charger (not to mention a whole bunch of other protocols) is especially handy. Also good to be able to read the e-marker chips in higher wattage USB C cables. It will tell you exactly what the manufacturer claims the cable power capacity and USB version (e.g. speed) from the chip. It has the look and feel of a quality product, along with quality packaging and well thought out user interface for such a simple thing. Pretty easy to figure out. My pictures show tests of a charger, resistance readings from a couple of cables, as well as a cable chip readouts. All cables tested so far haven't had a manufacturer listed. Not sure if that is because they are off brand cables not from major manufacturers that do not include an ID.. The manual is pretty good. The one thing it could really use is a menu tree for reference. I plan on creating one. Not sure if I will be able to add that to the pictures later. If so I will post it later. About the only tricky thing to learn is that for most of the PD tests you must power the unit from a 5 volts supply to the micro-USB (PC) connector so that the tester has power during interruption as the charger cyucles through the power changes requested by the test. I just tested the cables and charger from my last Banggood order. Moving forward I will test all future purchases.

FNIRSI FNB48P comes in a premium glossy carton case. The device's all-metal chassis seems very durable. The large 1.77" color screen is TFT and has 128x160 resolution. It measures 77.5 x 40.4 x 14.1 mm and weighs 37.7g. On the 4 sides of the device there are totally 6 ports, a button and a multi function switch. It even has a gravity sensor which rotates the screen when it is tilted or swivelled. The USB tester gives accurate measurements and works great with all fast charging protocols (up to 156W) I tested it. Here's a quick look to all main screens 1-6: 1) Basics screen (Voltage, Current, Power), 2) Capacity and Energy, 3) Equivalent Resistance, 4) Charging Protocols, 5) Voltage/Current Graphs, 6) Cable Resistance Measurement
