Looked it up at Wikipedia and now I know why my charger was examined at 4 different airports. This id states the level of emanated magnetic waves. Was allways able to bring it aboard, but left me puzzled.
The Wh can be easily calculated: Ah*V = Wh - Therefore: 30Ah (which corresponds to 30000mAh)*3.7V = 111Wh.
With many airlines, you therefore have to get an exception transport permit at the check-in, as most airlines set the capping at 100Ah. With an exception permit, even 150Ah are possible. However, some American airlines have generally limited capping to 100Ah. In this case, no exemption permit will help!
Aukey PB-Y7 is only compatible with Apple notebooks because USB-C Output (PD): 20V, 1.5 A.; too weak for Dell XPS 13.

Huawei Super Charge is not supported with this powerbank. But with Quick Charge 3.0, the phone is charged as quickly as with Super Charge 25W. However, the phone heats up noticeably.
26500mAh ist korrekt laut Herstellerseite. -> https://www.aukey.com/products/26500mah-usb-c-power-bank-with-power-delivery-pb-y7
PS: Ich habe den Fehler weitergeleitet.
Yes, it should be possible to charge a Surface Pro 4 (SP4) with this (provided a suitable cable for the Surface is available). The battery capacity of an SP4 is apparently 5'087 mAh, with this PowerBar it should theoretically (!) be possible to charge an SP4 5.9x. Test reports showed that an SP4 needs about 160 minutes to be fully charged (via PowerBars - of course, there are differences). As always, all information without guarantee ;-)
Approx. 1 time. Macbook pro has 100Wh battery capacity and the powerbank has 30Ah but only a voltage of 3.7Volt, which also results in approx. 100Wh, i.e. one charge.
Yes, I have just tested it. The Android phone had fast charging enabled and when I charged the powerbank, I put a meter in between and it charged at 3A which tells me it's Quick Charge.
Good question. I just tried it and when I plugged in the higher USB charge current, the USB-B port changed to output (instead of input). So I don't think it really works.
For me, charging is fastest (4-5h) with the MacBook USB-C charger.
Alternatively, there are Quick-Charge USB-C chargers from Aukey for the car and power socket (they also manage 4-5 hours for a full charge). Faster will hardly be possible.
Thank you for the idea of charging the Surface with the PowerBank - I also have a Surface Pro and this PowerBank, but unfortunately it doesn't charge with or without the keyboard. I have tried all connection options (USB A to C, USB C to C), but unfortunately the Surface always reports 'Device is not charging' and that I should connect the correct charger. Maybe I don't have a charging cable that supports PowerDelivery?
