# Can USB-C charger from laptop be used to charge USB-C Samsung phone?

I have a Samsung S8 phone, which has USB-C charging connector. I lost the original charger for my phone, but I have the original USB-C charger for my Huawei Matebook X Pro laptop. Is it possible to use this charger to charge the phone? Is the USB-C standard itself a guarantee that all the relevant characteristics will be equivalent?

Here is the electric info from the mobile phone charger (which has USB-A female output connector, and there was USB-A to USB-C cable which I lost):

``````OUTPUT: 5.0V = 2.0A, 10.0W
9.0V = 1.67A, 15.0W

``````

Here is the electric info from the laptop charger (which has USB-C female output connector):

``````OUTPUT: 5.0V = 2.0A, 10.0W
9.0V = **2.0A**, **18.0W**
12.0V = 2.0A, 24.0W
15.0V = 3.0A, 45.0W
20.0V = 3.25A, 65.0W
``````

(There is a difference in ampere and wattage for the 9.0V, is that a problem or is it that the device will just take what it needs?)

• Is the wattage really 18.0W? Wattage is Voltage x Ampere, so having the same V and A shouldn't produce a different W. Commented Oct 10, 2022 at 12:31
• @AndrewT. sorry, there is a difference in amperes too! I have edited the post. Thank you very much! Commented Oct 10, 2022 at 12:39
