Hello,
I have portable speakers (Supertooth Disco) that receive about 10v input (on the speakers written 12v but the inner batteries total is 10v).
I have a power bank of 18650 batteries:

The power bank has two ports of usb, each is 5v dc.
If I cut the two USB cables, and connect them in series to the powerbank, I will get 10v dc which is enough for my portable speaker, I suppose.
My question is- can it damage the power bank? because it is manufactured for 5v dc, and I am not sure, maybe if I create a circuit of 10v dc, the computer for the lcd indication might burn.
What do you think?
I believe in this forum there are people with more experience in elctornical circuits than me.
Thanks!
