Yet another pfSence ce router from Aliexpress. This time 2×2.5Gbit/s ethernet ports and Intel N200. With 16GB RAM and 256GB nvme. that kind of a lot for router needs, but just for test purposes.
Since Cisco SMB devices like RV320 are now end of life. And there are no good successors for this device. DYI routers on Intel N100 with 2.5 gbit ports and pfSense community edition might be an option to upgrade the router.
One HW example is Topton N100. That is a mini PC with Intel N100 + DDR5 single channel RAM + NVMe. It is fanless.
Spinner. with 256GB flash drive inside. It is kind of fun. Another Movespeed flash. Model YSUFUN5-256GSN. This time with an advertised speed 500MB/s
Both Type-A and Type-C ports work at more or less same rates.
256GB Flash drive YSUYVP-256GSN from Chinese brand Movespeed. It is advertised as a 1000 MB/s transfer rate. Made from metal. Got both type-C and type-A ports.
Type-C speed
WITRN C4 Pro
WITRN C4 Pro. Yet another power meter. TYPE-C only. Voltages up to 48v supported, also up to 10A current. USB-PD standard is evolving and currently allows 240W charging, so power meters need to be upgraded too.
WITRN has different software for firmware updates and to explore curves. Both PC software and firmware are in active development.

POWER-Z KM002C
ChargeLab new product. USB power meter with up to PD 3.1 support
With higher voltage (50v) and current (6A)
The device is not PC Software compatible with KM001 KM001C. First versions of application was about 90% Chinese. With almost no English translation.
(Update for 2022-04-05) But that is getting better. Version 1.2.8 is more usable with better English support
Despite the similar name, design is changed a lot since KM001C devices
Firmware 1.1.0 is unstable and has to be updated before using the device. Firmware update is possible for Power-Z Lab application.

Qingping CGS1
Qingping Air Detector (AKA ClearGrass Air Detector) is one of the best portable devices reviewed yet.
Impressive tech specs and design. Can be used both: as portable and not portable. And in a mixed way too. Good sensors for tvoc, t/rh, co2. High-resolution touch screen, Wi-Fi (that remember all Wi-Fi you were connected to), ambient light sensors, android and ios mobile app. And all that for a bit more than 100$ (incl. Delivery). For this price tag, it is a kind of flawless device. So the minor issues are not critical at all. Like it might have a different CO2 sensor (SenseAir S8 instead of Sensirion SDC30 for example) inside. But since S8 is not bad. It is still ok.
Pros
- 1800 mAh battery (~4 hours of battery life)
- Compact (9x9x7cm, 218g)
- Calibration (tvoc, CO2) may be done manually
- Correct t/RH and CO2 measurements
- High resolution display with good viewangles
- Touchscreen and good UI usablility
- Keep multiple Wi-Fi AP settings
- Weather and time sync from Internet
- Ambient light sensor
- Good thermal design and active airflow
- Mobile App and 3-rd party app support
- Wireless (OTA) update w/o app needed
Cons
- CO2 high level is starting 2000ppm.
- Disassemble is not trivial.
- There might be other sensors inside.
- No alarm clock (but should it be there?)

Pros
- 2400 mAh battery (~20 hours of battery life)
- Small and relatively lightweight (8x3cm, 145g)
- Calibration can be done manually
- Correct t/RH during normal operation
Cons
- Leading zero in CO2 display
- CO2 measurements might sometimes be wrong
- CO2 measurements delay is on power on
- CO2 measurement interval is 16/4 sec (10 sec average)
- t/RH measurements during charging is a bit incorrect
- Display view angles are not perfect
