Hi there

I've just bought an anker zola powerbank for a backpacking trip and am running into issues with it, I got it charged up to 91% at home, disconnected it and tried charging it up at work, which is where the issues started. The charger brick and cable work on my phone but when I plug it into the anker it either flashes the lightning bolt symbol briefly before stopping charging or not at all. Any advice? I'll be going to a very remote area for about a week so it really does need to be somewhat reliable.
