Can I charge my laptop with an external smartphone battery?

Question

USB

There is an external battery Canyon CNE-CSPB26R. It can charge players and smartphones via a USB-miniUSB cable (USB input, from there power is supplied via miniUSB (output) to the device). And there is a netbook that does not ask for a lot of energy, which I would like to charge using the above-mentioned external battery. And there is also a USB-USB cable (male-male), which, as I wanted, should have solved this problem by connecting the battery and the netbook. But it was not there. It doesn’t work if the battery cable is inserted into a USB hub with a mini-USB port, and the netbook and USB hub are connected via USB-USB. Is it even possible to make a battery designed to charge smartphones charge a laptop?
The battery works, tested on the player.
