The ad copy implies that iPhone lacks an nternal battery charging controller to optimize charging so here's their"smart charger" coming to the rescue. Nonsense. This isn't any "smarter" than any other C-PD PPS ac adapter/power supply which closely adheres to the USB PD specifications.. There is no internal circuit which "identifies which model iPhone -and- customizes the charging". It only does the former by showing what model is connected.
It's actually LESS capable than their other 45 watt adapters because it's missing the 21v PPS mode and fixed 12 volt PO:
Anker Nano 45W(A121D) Auto Mode Source Capabilities
Fixed 5 V, 3 A
Fixed 9 V, 3 A
Fixed 15 V, 3 A
Fixed 20 V, 2.25 A
SPR PPS APDO: 5 V to 11 V, 3 A
SPR PPS APDO: 5 V to 16 V, 3 A
edit: Proof: I connected an iPhone 13 to the Anker 313 'ACE 2' Black Iteration Special" A2643 45 watt from the $12 Target deal I posted last August. Battery level was 30% to trigger fast charging, A certified 3 ft cable was used. The iPhone 13 internal charge controller automatically reduced the charge rate to 5 volts 15 watts because it did not see the Apple Fast Charge protocol. When the cable was moved to the Otterbox Premium Pro 60w which has Apple Fast Charge the charge rate was observed to be 9 volts 20 watts, the maximum rate allowed by iPhone 13.
Secondly, no long term testing has proven that reducing the charge rate extends battery life in modern cell phones. Apple designed the iPhone's internal charge controller to limit charge rate conservatively well below the actual capacity of their batteries. There is no proven advantage in reducing battery temperature further. The "care mode" isn't needed. It merely hamstrings the charger to limit its output to 20 watts max.
Smart plugs are the best way to control charging. I set up an automation to automatically turn on the plug for 30 minutes before I rise or I just use voice control. "Alexa turn on the phone charger for 30 minutes".
The power meter is of no practical use to me. USB power meters are generally used only once to verify that a particular adapter has the ability to charge at the maximum rate allowed by the device and to verify that it is providing the correct voltage during high speed charging when the phone battery is in low state of charge.
I'd rather look at the device to see the state of charge. Most show the charge time remaining. If they don't then I know by experience how long it will take.
By simply feeling heat at an adapter I know how hard it is working. If the phone battery is depleted but the adapter isn't getting warm then it's obvious that the cable has gone bad. There are never any surprises leaving home with the phone not charged.
