Able to power rock pi 4 using 12v/2a power supply, but unable to charge phone with it.
Well i got to it recently after some time to test it properly. And it is not worth the money, definitely not able to transfer more than 1A, as phone is not even trying to charge using 27w power adapter, and unable to power SBC like rockpi4. So please, do not buy it and save your money for something that works.
Little thick but it works - thanks
