Have you considered repairing the charging port?
Thanks for answering
I have tried 3 or 4 usb cables for charging and it's same.. Also i can't open it, it doesn't have any screws so i can't measure anything..
The powerbank is pretty new but it doesn't have warranty.
Is there a way to open it somehow in a repair store.. I guess like they are opening the smartphones with non-removable batteries ?
The powerbank device does not have any screws visible, and it may not have any at all. That is because it costs less to design it to either snap together, be or to be sonic welded , or glued. So what you need now is some good light and probably a magnifier, so that you can examine the case and locate the seam between the halves. That seam will go all the way around the case and hopefully look a bit different. The other possibility is that the halves of the case snap together, in which instance you will probably need to break the snapping hooks and then glue the case closed after repairing it. In either case, my way of opening glued shut cases is to use a quite sharp thin knife blade, with the sharp edge against the crack of the seam, and gently tap on the back edge of the blade to start the joint cracking. As soon as the joint cracks a little bit, advance the knife blade to a section that has not yet cracked and tap on the blade to break the seam some more. But be very careful while doing this to not cut your hands. I always rest the device being opened on a covered surface so that I do not damage the table while working. The whole process is a lot like cracking open a walnut. It is also very important to not let the sharp edge go into the case and cut things inside.
The output port is not the same as input ...so you could possibly damage itWhat happens if I try to charge a powerbank through the output port ?
