Can I use a Quick charge 3.0 powerbank on my Quick charge 2.0 phone?
Hello everyone, just wanted to know can I get this Aukey Power Bank and use it with my HTC One M9 (which has quick charge 2.0).
Will there be any issues or am I good to go?
Thank you in advance for the responses.

Yes, although it may not charge as fast as it could. 3.0 negotiates a range of voltages based on what the device/charger/cable/connection can handle, whereas 2.0 just has slow and fast. If the d/c/c/c can convince the logic on a 2.0 that it's good to go for hi-power charging, then then hi-power charging it is and excess energy gets wasted as heat. 3.0 avoids that by negotiating.
I see, I was mostly wondering if there will be any issues regarding heat or too high of a voltage, but thank you for your detailed answer. I just found out on the qualcomm website that Quick Charge 3.0 is backwards compatible.
Your phone controls the charge circuit, depending on the max output of the power source your phone will adjust accordingly. Your phone will never draw/charge more than would be safe.
