Vakoss Power Bank Not Charging or Turning On: Single LED Blinking from 4 LEDs

Good evening
I have a problem with the vakoss bank power
the power bank does not charge and does not even want to turn on under the charger
only one LED from 4 is blinking
What could it be?
Am I doing something wrong?
Is something wrong with him?

I think that there is no philosophy in this, so nobody can help me today, I will go and give away the equipment.

You do not load, how can you be sure? Changing the cable has helped, what time trials? Flashing of the last LED probably signals discharging.

Usually when charging a powerbank it is signaled on it via LEDs.
I suggest a replacement of a USB cable like a colleague, if that does not help, try changing the power source.
If you continue to have a problem then most likely the USB powerbank socket is damaged.

It looks like I've just cut the cable 3 times and every other one. I tried to run under the PC port. Under the charger from the smartphone. Under the charger from the phone. Under the TV port and everywhere the same

And it is suggested that the power bank itself (landed from 5h) and all of this power LED flashes. Only that I thought she could because the first 25% was loaded and I left him. After 5h, nothing se diminished. And I'm sure that Ne Ne is loading because I do not want to turn on

You got a damaged copy.

as you say Artur. I was exchanged from my hand
