Hi I recently bought PowerCore+ 20100 USB-C and when I tried using it to charge my phone, a Redmi K20 Pro, there is no “quick charge” notification that pops up on my phone. I tried using all the cables that I had. The cable that came with my phone, the A to C cable from the PowerCore+and the C to C cable from the PowerCore+ but none of them can quick charge my phone. Only when I plugged it into the wall charger will the “quick charge” notification pops up. Does this mean that my product is defective? Incompatible? Should I get a refund for this?
That phone requires a Quickcharge 4.0 or USB-C output of 18 to 27 w to fully enable fast charging. The baterypack you have is only capable of outputting 15w of power which may not be enough to trigger fast charge on your phone
That model PowerCore will not fast charge any device. It supports standard 15W USB-C output. It does not support fast charging tech such as USB Power Delivery, Quick Charge, etc.
As your phone supports Quick Charge 4+ (meaning it’ll work with either USB Power Delivery or Quick Charge 3.0) you’d need a different model power bank to get fast charging speeds. The Anker PowerCore Speed 20000 PD has the same capacity as your current power bank. And supports up to 24W USB Power Delivery via its USB-C port. That would fast charge your phone.
Depending on your habits you may not need fast charging. If traveling you can connect the power bank to the phone while the phone has a nearly full battery. Fast charging typically kicks in below 70-80% charge. Connecting early keeps the phone’s battery at 100% while it draws from the power bank first. This also has the benefit of giving you maximum uptime with the phone.
Similarly if charging the phone overnight lack of fast charging isn’t a problem. The 15W output is enough to charge the phone fully over several hours.
If you do want to upgrade your power bank any Anker PowerCore model with “PD” in its name will work for you. They are available in 10,000mAh, 20,100mAh, and 26,8000mAh capacities.
