5v 1a USB power supply, Is it ok if i power my nano through the USB port?

I fried a nano by using the VINN port with a 12v1a power supply. I don't want to do the same mistake twice so i was wondering if it is ok to use the USB port as a power port and supply it with 5v1a phone charger? Will it fry my 2nd nano? Thank you!

There's nothing wrong with the way the power is supplied, but it's likely that the other components that connect to the Nano are the cause of the burn Nano, so it's more likely that you'll get better advice if you show all the connections.

This may help?

I think this is the way i fried it, thank you! 5v phone charger works, it doesn't heat up at all.
