Hi everyone. I've been waiting for this charger to go on sale for a few months now. It's the lowest price I've seen on Amazon recently. if you are in the market for a standard USB charger to charge your iPhone or iPad, this Anker deal isn't too bad. Make sure you clip the coupon that'll bring the price down to $8.09.

This is not a USB-C or PD charger.

No. Post a link if you can find one that supports this. No, QC does not "wear out your battery faster".

If you turn off fast charge then the charge voltage should limit to 5 V before it gets to the battery. Lower voltage means higher current, Higher current causes more heat. You would also need to use a low amp charger and that still will not guarantee longer life.

Time: QC pulse charging allows the battery to quickly absorb charge particularly 0-70%. Time plus heat determines wear. QC reduces the amount of time the battery is at elevated temperature.

Accubattery is a good app to track wear. Batteries can be cycled a finite number of times. Charging to 100% uses up one full cycle. Charge to 72% results in less than a tenth of a cycle is consumed. If the battery is drained completely repeatedly the battery degrades over time from chemical reaction at low SOC. Although impractical for most, keeping the battery between 30-70% should give the longest life. "100%" on the meter isn't really 100% of battery capacity. Max charge is set by the software and can change with updates. "Battery Health" is calculated in the app and in the phone. It reports the actual capacity compared with the spec for the installed battery by tracking mAh in/out. It should decline only gradually over time. This way the user can see for him'her self what effect is, if any, of a charger, charging protocol or user habits.

Heat will damage the battery whether its charging or not as in leaving the phone in a car or in the sun. Up to 109 F is considered normal. One may strive to keep heat lower but since time is a factor in aging such measures haven't translated to getting more than three years out of the battery anyway.

Samsung battery management system is designed for QC, AFC and USB PD charging protocols.. Note 10+ adds PD 3.0 PPS support. The management insures against over-temperature, over-current and over-voltage. As the phone heats the charge rate tapers.

Owners can monitor the battery temperature from settings or more conveniently from apps which use the phone's sensors to provide real time and graphs over time which also track other parameters. Internet myths stubbornly persist. Individuals can make their own observations from phone sensors and data.

This is incorrect. QC is a standard used by Qualcomm chips that uses 9V charging. It will not wear out your battery faster since it controls the amount of amperage provided depending on what % is charged, as most modern smartphones do. Buck converters also are more efficient (less heat dissipation, better for your battery). Look at the charge current graph for an example: https://www.google.com/amp/s/www....89780/amp/

No need to apologize for it not being PD, at least for an iPhone. A regular 12W charger is fine for most uses, and saves money on charger and cables:
https://www.macworld.com/article/...pters.html - See the iPhone X chart for example

USB PD charging is really only needed for when (1) the phone is at a fairly low charge and (2) you really don't have much time. Worth having one in your car and one at home, but no need to use it on all your chargers. It doesn't add anything when you have plenty of time to charge, or are charging the last 30% or so.

For this price it's a great alternative to the much more expensive Apple fast charger if you don't have an iPhone 11 Pro or pro max. If I didn't already have one I'd be all over this deal.

If I only have 1 cable plugged in and charging, will it be using 24W or 12W?

Quote from Tisser12
:
IQ determines the maximum power that's safe for the cable/device in normal charging mode. QC is a step above that. Think of IQ as sort of a "level one" fast charging, kind of QC for devices that don't have QC support. And then actual QC would be "level two".

Do keep in mind that using QC will wear out your battery faster. It uses much higher wattages thus creates more heat. I recommend that if you don't need it, turn it off. IQ will charge your device plenty fast on it's own. (If you have a QC charger and have QC turned off on your device it will charge using IQ usually)
This is incorrect. QC is a standard used by Qualcomm chips that uses 9V charging. It will not wear out your battery faster since it controls the amount of amperage provided depending on what % is charged, as most modern smartphones do.
