USB Fast Charge Tester

Overview

Highlights

The FNB48P USB tester is a high-reliability, high-safety USB voltage, and current detection meter and a mobile communication terminal fast charging trigger. It has a 1.77-inch TFT LCD display, integrated USB-A, Micro-USB, and Type-C interface. Use a dedicated 16-bit ADC, PD protocol physical chip. It can be used to measure the power supply or power consumption of products such as USB interfaces, mobile phone chargers, and U disks; measure the charging power of mobile phones and the input and output of mobile power supplies; test the fast charging protocol of chargers.

USB Tester with LCD Display
FNIRSI FNB48P USB tester has a 1.77-inch TFT LCD display, integrated USB-A, Micro-USB, and Type-C interface. It is a high-reliability, high-safety USB voltage, and current detection meter and a mobile communication terminal fast charging trigger. The gravity sensor enables you to automatically switch the display direction.

Multifunction USB Digital Tester
Uses external 16-bit ADC, PD protocol physical chip, this USB tester can be used to measure the power supply or power consumption of products such as USB interfaces, mobile phone chargers, and U disks. Also, it can monitor the voltage, current, power, resistance, capacity, temperature, D+/D- voltage, etc, and test the fast charging protocol of chargers.

Fast Charge Protocol Trigger Detection
FNB48P supports trigger detection of various fast charging protocols, QC2.0/QC3.0 trigger, FCP/SCP trigger, AFC trigger, PD2.0/3.0 trigger, VOOC/WARP trigger, and Super VOOC 1.0/2.0 trigger. The above protocols all support automatic monitoring. MTK-PE automatic detection. Support QC2.O to PD2.0 protocol conversion.

Parameter Detection and Recording
It has the highest six-digit display of voltage, current, and power, and the highest resolution is 0.00001 (V/A/W). 10 sets of switchable capacity, power, and time statistics. 1 set of voltage and current curve records, maximum support 9 hours. Support low-speed waveform (voltage, current, D+/D-) drawing, 2sps->100sps sampling rate. Support high-speed ripple (voltage, AC coupling)drawing, up to 3.2Msps sampling rate.

More Detection Functions
FNB48P also has many functions, including the internal resistance measurement of the wire by the differential pressure method, E-Marker cable chip reading, DASH cable data reading, the record of startup time, onboard temperature measurement, PD monitor, etc.

keyboard and case is phenomenal, trackpad is borderline unfunctional
Color: Black
I bought this case, because of the keyboard and trackpad, i wanted to use my ipad more like a laptop. the keyboard is phenomenal and certaintly better than other cheap ipad keyboards i have tried, I can actually use this one without having to repeatedly slam or hard press certain keys and can actually have a flow of typing. additionally, everything else regarding the case itself is amazing. it isnt cumbersome or bulky and it is very easy to swap between ipad and laptop mode on the fly. the trackpad however is genuinely unusable. the sensitivity on the trackpad is horrid and I cannot figure out how to change it, and additionally, clicking using the trackpad is outright impossible. you try to left click, it registers as a right click, or you try to click and it instead snaps your cursor to the bottom of the screen instead. it is also impossible to use any gesture functions with the trackpad, even something as simple as scrolling up and down or left to right is impossible. it is outright impossible to have any kind of workflow using the trackpad. it is unfortunately just a lot easier to use the keyboard and touch screen! its a shame that the keyboard and case itself is very nice too, so I will now have to spend more money on a separate mouse, which is additionally ANOTHER item i will have to carry around, just to make what I already bought work the way I expected.
