    I have tried searching the forum and have got a response on lower power rating charger for e.g. 5V / 2.1 Amps, but i question was specifically with a higher power rating charger. I have an HP elitebook 360 which comes with a USB C charger with following ratings
    65W Max (5V/3A or 9V/3A or 10V/5A or 12V/5A or 15V/4.33A or 20V/3.25A). I believe the charger will change the configuration based on the end point .

    My question is can I use this charger to charge OP7Pro? If yes, are there any down-sides to it?

    Thanks in advance for answering.

    Kind Regards,

    Bro, never try this, even if you use the 65w charger the phone only can take upto 30w max which has been restricted in both hardware and software.

    Moreover if any software or hardware issue occurs then the device will no more restrict the current flow that cause higher current flow or fluctuations which may lead to battery damage or higher chance to explode.

    So always try to use in box or original chargers and stay away from such danger.

    You can use the charger, I sometimes use my macbook pro charger when I don't have my warp charger with me...

    Power Delivery Type-C compliant chargers should be able to adjust the output based on the device they are charging. This is part of the PD standard. Still, there is a risk involved in this and you should use the provided charger instead.

    Sorry, but this is not true. It will not "definitely blow the resistor" as you state. As you can see above, @Liehjan has did it in the past. PD devices are designed to allow this.

    If it is USB PD compliant, no it won't.

    It'll just charge at 10w (5Vx2A) like the spec states it should.

    VOOC/Warp Charge is only usable with the official OP stuff, other equipment will just default to standard USB charging.

    As I already said earlier, been using a macbook pro charger with my 7pro for the last 4 months.. My phone is still completely fine and not damaged in any way!

    Hi All,

    Thank you very much for all your responses. This helps. I did try to charge the phone using the 65 W charger and it charges normally. I ran the "Ampere" app and could see the phone was charging at about 1.5 to 1.7 Amps with 4Volts. I guess this is normal. I have seen the phone charge at normal rate. The phone does not get heated when charged using the 65 W charger. I do not know the internals of this phone but my common logic from electronics says that the resistor will blow if it heats up. it heats up if you pass either more voltage / current thru it. From the Ampere app above, i can see the voltage and current supplied and drawn are under the ranges and there is no heat, so i am quite confident that internal resistor may not blow up.

    Having said this, i have now charged the phone multiple times in last 2 days and have not seen any downside.

    I hope my inputs & the inputs above helps other who are looking for such information.

    I would now request the admin to close the thread if possible.

    Thank You All!!
