Pixel 7 Fast Charger

[R1945]

I am using a travel charger spec say 5v 2a, 9v 1.67a.

It charges the Pixel 7 quickly, very quickly.

However, the travel charger gets warm.

Will the charger cause any problems with the Pixel 7 charging.

It's not unusual for a charger to get warm. Is it getting uncomfortably hot, though? And what brand is it? I wouldn't be worried if it's a well-known brand like Anker or Belkin -- but if it's a no-name or off-brand charger, I'd be more cautious, because quality control would become a factor, and a bad charger can be a fire risk.

I am little confused about fast charging on the Pixel 7. My power supply says (5v 2a, 9v 1.67a.). That should support fast charging. So I purchased a MakerHawk USB multitester to verify charging specs, also to check if USB ports or Cables are bad.

So charging the Pixel 7 using this power supply the tester reads 5v, 1.01a, that is not fast charging.

The power supply says it can charge 9v. What I am not understanding. Why is not the Pixel Fast Charging.

I believe the charger has to support PD 3.0 (PPS): https://www.androidauthority.com/best-google-pixel-7-pro-chargers-3219135/

Charger Output: 20V 1.5A 30W Input:100-240V. To get the fast charging feature, check if your device is USB-C PD (Power Delivery)-enabled before purchase.
Is PD (Power Delivery) and PD 3.0 (PPS) the same thing?

Will the above fast charge the Pixel 7?

 

[B. Diddy]

PD 3.0 is Power Delivery version 3.0. Are you looking at a product listing? Does it say what version of Power Delivery the charger supports? If it's <3.0, it might charge medium-quick, but not be able to reach maximum charging rate.

Using a MakerHawk USB Multitester charging thru a USB Port, and comparing it to AccuBattery APP for the Pixel 7, the Multitester shows significantly more amperage and charging power, than the AccuBattery charging readings. The USB Tester showed about 7 watt charging to the Pixel 7, AccuBattery showed approximately 4 watts with big fluctuations but never getting as high a 7 watts.

Accubattery say that the cell cannot be charged with actual 9V at any given moment or the battery will explode. They say that there is not a single regular smartphone cell which could be charged with over 5V, with each smartphone having some sort of module that will always prevent the cell from charging the cell with more than 5V.

If the above is true how will a high voltage quick charger quick charge a phone battery.

Are smartphone cells actually charged with 9V using QC and other techniques or does the smartphone always step down the voltage?

I'm having this disagreement with a good friend of mine regarding charging voltage of the cells inside modern smartphones when quick charge, USB PPS and other techniques are used. Let's take as an

Sorry, but I don't have that level of technical know-how. Maybe look at this article: https://www.androidauthority.com/usb-power-delivery-806266/

Good article, I did buy one. It says PD/PSS. This is the charger with high reviews that say it will charge anything fast.

It was cheaper on eBay.

Thanks

Stick to PD 30w charger stock or name brand anker , also in settings>battery>adaptive charging toggle on will change the speed at a percentage the battery is at.
So if you dont go with google then try good known name brand like anker .
Ill show pictures of my stock 30w PD google charger specs

 

[mustang7757]

You will see at different voltage it will give different watts 9v/ 11v/ 16v /20v etc..

This fast charging is very confusing regarding what you need??

I purchased a 65W GaN USB-C (PPS) Charger. It has 3 ports USB-C1, USB-C2, USB-A.

Below are the specs that I do not understand?????

Can someone explain what these specs mean.

I am assuming for example if you connect USB-C2 and connect UAB-A on the device you simply a 5V charger????

So different connection combinations give different charging specs.

Is a Pixel 7 compatible with GaN chargers?

Thanks

I'm not familiar with gaN charger but I would stick with recommend name brand or stock 30w PD charger

Gallium nitride chargers are more energy efficient and compact, so they generally charge faster without as much heat generation (in the charger, that is): https://www.belkin.com/products/product-resources/gan-chargers/. I have a couple of GaN chargers, and they work great for my Pixel 7 Pro, Chromebooks, and everything else. But as mustang7757 says, I would stick with known brands to be safe. Apart from the main manufacturers like Google and Samsung, other good brands include Anker and Belkin. Chinese brands with odd names in all-caps are a bit more suspicious, but Nekteck and UGREEN seem to be reviewed pretty well (I have a Nekteck charger that works great).
