I received an email about a new product from FNIRSI. A new USB tester called FNB-C2. And it looks really good.
It supports the PD3.1 standard, can measure up to 240W (20V/6.5A), can read e-Marker USB-C cables, and can also emulate them!
I have written about FNIRSI products often here. Initially, I was somewhat disappointed; however, the products from the last two reviews pleasantly surprised me.
We will see how the FNB-C2 performs; it promises a lot, and with a price under a thousand crowns, it is indeed an interesting product.
I tested one USB tester, the FNAC-28, and it didn’t turn out the best. On the other hand, it is the cheapest option among their testers, but USB-PD support is a must for me.
What will this one be like? It promises a lot.
Allegedly, it has a 20-bit resolution ADC converter for measuring voltage and current. The voltage measurement range is from 4 to 50V with a resolution of 0.000001V and an accuracy of ±0.2‰ + 2 digits, while the current measurement range is from 0 to 6.5A with a resolution of 0.000001A and an accuracy of ±0.5‰ + 2 digits, allowing it to reliably measure output power up to 240W.
Author’s consideration: If the tester has a resolution of 0.000001V, i.e., 1uV, and an accuracy of ±0.2‰, i.e., 0.02% + 2 digits (considering the measured value). Then the measurement inaccuracy (for 5V) could be ±1.002mV.
In addition to USB-PD 3.1 EPR, it also supports other fast charging standards – UFCS, QC2.0/3.0/4/5, Huawei FCP/SCP, OPPO VOOC/SVOOC, and VIVO VFCP.
The FNB-C2 can identify the e-Marker in a USB-C cable. You can easily verify whether the cable can actually handle the promised power. The USB tester can behave like a cable with or without an e-Marker chip.
There is also the option for real-time monitoring of both temperature and voltage, current, and thus power.
I have already ordered the tester. Delivery is within 14 days, and it is currently on its way via Zásilkovna.

The price is 851 CZK excluding VAT and shipping, making it cheaper than its predecessor FNB58 (1288 CZK).
