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.
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.
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.
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.
Yet another highly portable standalone CO2 Meter. This one with great battery life. One of the recommended devices. It is not absolutely flawless but is ok to buy. It got fast, accurate, and low power t/RH sensor (Sensirion SHTC3). Its CO2 sensor is kind of average (Cubic 1106 probably). Charging 5v 1A
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
That is quite a long story of smartphone makers are trying to create powerful Qi charging devices. And usually, they are all fails. Wireless chargers are still noticeably slower than wired. And also less power-efficient. And also not reliable. With some previous wireless charging docks, you someday waking up with your phone not charged at all. And there are a couple of reasons for that. First is coils misalignment, which reduces all (speed, efficiency, and reliability). The second is power loss and related overheating (affects speed and efficiency). So what is good about Apple MagSafe 15W Qi charger. It solves the first issue. Coils are now aligned. So you can be more or less sure that you will get your phone charged. But it mostly ignores the second. Qi charger is still overheating. And that is slowing down the charging process. Yes, it is an aluminum body, and that is kind of good news. But that is definitely not enough. So for a period of 3-5 hours of wireless charging, you will get 15W only for a short period of time. Usually, it is about 5-7 minutes. And the most interesting part there is 7.5W charger may charge faster than the 15W charger just because of less initial overheating.
So the usual charging may look like graphs below
That is just about 4 hours. But results may vary a lot. That is highly dependent on temperature (room temperature, phone temperature, table temperature), on do you charge with a charger below or above the phone. Do you use a case or does the phone do some background tasks. Do your air moving in the room. It impacts Qi charging speed much more if compared to wired charging.
Wired charging from same 20W power adapter:
It is for the same conditions, same case, same temperature, same table. Just about twice faster. And power consumed is 14.5Wh instead of 22Wh to charge an iphone 10.78 Wh battery (while phone is on, but not in use). That is about 3 times more energy lost on generating heat.
So How to get 15W we pay for? That is easy :). You need to place the phone (without a case) in some cold place with airflow for at least the first 30 minutes of charging.
And if you got proper cooling you will get something like:
Still a bit worse than wire charging in the room. But anyway we got our 15W Qi. It exists and it is fast. (That is kind of sarcasm).
So what is wrong with Apple Magsafe Charger?
it is slow
it consumes more power
it is expensive
One more thing.. about power consumption. Idle power consumption is also might be an issue. Lightning cable inserted in 20W AC adapter consume much less power (0.0025W) in idle mode (when you do not charge anything) than MagSafe charger (0.34-0.5W). So if you kind of eco-friendly person you better plug out the MagSafe charger every time you are done with charging.
