    I am going to answer my own question about ports etc. I realise that I couldn't see the specification sheet on a mobile device - OK on a laptop. I did some experiments. The unit takes approx 50 microamps from the battery when off. When the battery is first connected , the unit takes approx 48mA and the two large USB sockets turn on producing around 4.94V. With no load they turn off again after some seconds, back to standby current. Pressing the button on the side, switches the unit on again, and it turns off some seconds later with no load. With a load it stays on. Charging can be via the micro USB, lightning connector or USB-C. The output of the unit goes from 4.94 to 4.87V when charging., and the unit digit of the display flashes to show charging. The display shows the percentage charge in the battery, although I didn't see numbers in the spec sheet for that. There is a problem using it as a no-break supply, because disconnecting the charging supply causes a momentary break in the output. I have discovered that before with other battery packs. Reconnecting the charging supply does not cause a break. I may experiment to see if a capacitor on the USB 5V out would hold up the supply as the input turns off - that would make it much more useful.
