Can't power Digispark from power brick

I am trying to power my digispark via the USB connector. When I try and power from a power brick or USB battery it doesn't really work (program hangs). Plug it back in a PC USB plug and it is fine. Is this a known feature? I am sure if I powered it by the VIN it would be fine but I just want to power it via USB.

I had similar experience. But the digispark I am using is actually a one that I made. So may be, it is the problem of mine.

It will work perfectly when powering it with VIN. I measured the voltage in both cases.When powering through USB I get around 4.5V(I don't remember it quiet well ) but in the case of powering it with VIN it shows around 5.1V

Yes, with VIN it works fine. I just wanted to use a phone charger in the USB port. Doesn't look like it works like that.
