Laptop charger for pixel phone

RRZishe

Hi,
I have a LG gram laptop that comes with a very thick type C charger. Sometimes I use it to charge my pixel, when I do my pixel charges faster. Is this an issue? Will it kill my phone's battery?

Thanks!

RRZishe Voltage on the charger? Should be fine either way

"The Pixel 6 & 7 is capped at 21W
The Pixel 6 Pro & 7 Pro is capped at 23W

Pixel devices do not support 30w or 33w charging. That doesn't mean you can't use a 30w charger with them, it just means the phone won't charge any faster." -reddit

USB-C cables are not made the same. Different cords and their power supply can handle different outputs and data speeds

Wattage = voltage × amperage

Higher voltage than designated for a device will damage the device. Higher amperage does not.

Most new usb c power adapters are capable of outputting different voltage outputs: 5v, 9v, 15v, and 20v. These are the new standards.

You must check to see what the output voltage of your adapter is and if it supports variable output and what those outputs are. You must also check what the voltage input for your device is and if it supports variable inputs and what voltages it can handle. If an adapter does not output a voltage that matches the input on your device then that's dangerous and will harm the device. A device will draw up to the maximum amperage it needs and can handle at a given voltage, if its available, but no more.

Faster charging is convenient, however it also reduces you battery lifespan. Charging at a lower amperage takes longer but puts less stress on battery during charge.

So i personally have dedicated 5v 1amp chargers specifically for my phones to avoid fast charging. I avoid new high power adapters.

raccoondad It says 65 W 🤷🤷🤷

You are definitely overdoing it on the voltage, stop using it

[deleted] Did I kill my battery?

[deleted] USB-C is able to control its voltage if I am not mistaken and will cap its charging at 21V

From what I understand the cable negotiates its power outage and if it cannot then it just does a slow 5V charge

raccoondad I hope so, but why does it charge faster than the regular charger?
Thanks

RRZishe Because the cable and its power supply have their own capacity, your phone however can handle up to 21V (a lot!)

traditional USB for example is only 5V, so if you had a traditional USB to USB-C converter in place it would only have the ability to charge up to 5V

Some cables and their power supply are just cheaper, but they have a cap that's far below what would be considered 'fast charging'

I use a 100V cable myself, never had an issue in terms of heating or battery issues. From what I understand that's because it limits itself to just what my phone can handle

raccoondad Thanks for the info! It's interesting that the default charger isn't the fastest it can be though

RRZishe The cable probably can, but your power supply probably can't. Google doesn't supply power blocks anymore </3

raccoondad I bought the Google power block

RRZishe '30W USB-C power charger' -Google store

Odd...I sadly don't have a device that can verify the cable that came with my device, so I just imagine the cable itself is capped at a lower rate

Regardless, power isn't forced into the phone, it draws what it needs. So if you get a faster charge, I would use it.

Just throwing this out there - the Anker 736 has been awesome as a universal charger (100w total). I use it them for my notebooks and power-hungry mobile devices (30w).
