Since USB 2.0 became a standard for charging port there are a couple of things happens. Devices got more and more battery capacity and that is why many fast charging protocols appear to overcome USB 2.0 default 2.5W (5v 0.5A). Those protocols were necessary to keep the same charging time with larger batteries. Some of those protocols were part of USB standard (like USB Battery Charging and USB Power Delivery) and some were not (like Apple 2.4A, Qualcomm QuickCharge, Mediatek PumpExpress+, and a lot of others).

Most chargers and power banks support only some of those fast charging protocols. So usually you will not get the fastest posible charging for all of your devices from the same source. For example power banks with Mediatek PumpExpress support is exceptionally rare devices. There are a number of power banks with Qualcomm Quick Charge or USB Power Delivery available, but not with Mediatek PE+. So below is three 10000 mAh power banks I found with MTK-PE support.

In the future fast charging might get some common ports and protocols. And it seems it will be type-c with USB Power Delivery in use in most cases. But for the moment it is several standards that provide more power than a standard USB port. Those standards are mostly not part of USB specification. And it is kind of unusual to have charger or power bank that support multiple fast charge protocols for different devices. That cause slower charging of some phones using charger or power bank designed for another. For example, at the moment most Qualcomm and Mediatek based Android smartphones have different fast charging standards. It took some time for me to find MTK-PE+QC3.0+Apple2.4 charger and power bank.

So the power bank is Tqka BA058
