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
List of supported protocols
- Qualcomm Quick Charge 2.0 (QC2.0)
- Qualcomm Quick Charge 3.0 (QC3.0)
- Mediatek Pump Express 1.0 (MTK-PE)
- Mediatek Pump Express 2.0 (MTK-PE2.0)
- Huawei Fast Charge Protocol (FCP)
- Samsung Adaptive Fast Charging (AFC)
- USB Battery Charging 1.2 (BC2.1)
- Apple 2.4A
Test charging and recharging
100% charged power bank is able to fully charge two phones:
- Umidigi Z2 Pro (3250 mAh) – 1h 53m – 16.3 Wh – MTK-PE 9v
- iPhone Xs (2658 mAh) – 2h 12m – 13.3 Wh – Apple 2.4A/2.1A
- Tqka (10000 mAh) – 2h 50m 33Wh – QC2.0 9v
