Can I Charge My Phone with Laptop Charger Type C

Share with friends

Can I Charge My Phone with a USB-C Laptop Charger? This is a common question people wondering if it’s possible to charge a mobile device with a USB-C laptop charger.

I have seen this particular question in an online community where a questioner asked if anyone have an idea about using laptop’s USB Type-C charger to charge OP3T.

The question: Hi guys! I was wondering if it would be possible to use my laptop’s USB Type-C charger to charge the OP3T. Does anyone have any idea if that’s compatible?

Answers:

1. I’ve actually grown a pair and tested it. The notebook charger charges my phone (standard speed), but the phone charger, does not charge the laptop ((unrecognized device plugged in” message shows up).

Mistery solved. Hahaha

what phone is it ? as you said it could be a coincident. I will test it with mac usb-c charger and let you know. If you use named brand chargers and cables “usually” safe.

How did the Macbook charger work?

I didn’t know that, I just know that a friend of mine killed his phone by using my dash charger. It could have been caused by a hardware failure in either the phone or my charger though.

It’s written DC output 20V 2.1A. Would it adjust to the voltage used by the phone or would it fry the whole thing?

Normally it should but I would contact razor first if it doesn’t state 5V anywhere on it.

this is the issue they are trying to fix with this is the issue they are trying to fix with USB-C PDI haven’t tested on oneplus 3t but if done correctly usb-c should negotiate and only supply the right voltage to the device.

It will most likely charge, but the amount of power coming from the charger is probably a lot higher than your battery can handle. So it will most likely destroy your phones battery.

but not dash Charge

Correct, as stated in my first response. Only 5V 2.1A

You know nearly all USB C chargers support 5V charging. in that case the phone will handle charging like normal and everything will be fine.

10. Not sure if a different cable will be compatible with dash charge. It will charge, but may be at a slower speed and might heat the phone also.

11. It will most likely charge, but the amount of power coming from the charger is probably a lot higher than your battery can handle. So it will most likely destroy your phones battery.

12. in theory yes it should work. Only at 5V 2.1A though. Unless the charger itself explicitly says it doesn’t support phone charging.
