    Anyone else tried using a magnetic charging cable?

    When the phone was brand new, the 'lightning bolt' symbol appeared on the battery icon on the top right corner - indicating that it was charging. I left it there for 10-20 minutes and if I remember correctly, the phone didn't actually charge.
    Setup: Magnetic cable + 2.4A adapter.

    I charged the phone using the OEM cable and adapter, downloaded & installed updates.

    Tested the magnetic cable again by connecting the cable to the tip attached to the phone, the LED indicator light becomes white, the percentage of the battery will show when in lock screen but the phone won't charge.

    Tested the cable & brick on a different USB-C device and it worked properly.

    Replaced the 2.4A adapter with a 4.0A one and for ONE moment, the Razer Phone registered as "Charging Slowly".

    Unplugged the cable from the magnetic tip and brick, moved to a different outlet and reconnected everything. Nothing.

    Would really appreciate tips on how to solve this as having only 1 OEM cable & adapter is too much hassle. The phone gets a lot of use so intermittent charging with magnetic cables at the office, home, and car is a huge thing for me.

    Thanks!

    PS: This is the cable I'm trying to use: https://www.amazon.ca/gp/product/B078K7Z7WX/ref=ask_ql_qh_dp_hza
    It works on my other devices. It's just the Razer Phone that's being a pain.

    Some magnetic charging cables do not utilize the same pins to deliver power safely.
    You need more than three magnetic pins to perform power negotiation properly.

    Thank you for the insight.

    I looked at the magnetic tip and and saw 4 pins on each side.
    On the side that connects to the cable, there are 8 pins.
    On the cable itself, there are 4.

    However, this doesn't explain why the cables work for my other devices (iPad Air 2, One Plus 5) w/o problems.

    Do you have more thoughts regarding this?

    Thanks!

    You need to see what exactly each of those pins do on your cable, then make sure each of the pins are present on both sides of your USB-C port on the magnetic connector.

    If you're missing any of the pins, your power negotiation will not work properly. Newer QuickCharge standards have stricter protocols to keep your battery safe. Some of the other OEMs use old standards or proprietary standards that do not have such protections.

    I compared it to my OEM and other working cables and found a massive discrepancy. I'll opt to return the cable instead.

    Thanks a lot!

    Follow-up question, for me and those who might see this, do you have any magnetic cables to recommend that work well with the Razer Phone?
