Why does my Raspberry Pi flash a red light?
Seems there is no problem at all with your Raspberry Pi. A constant red light, the PWR led, indicates that your raspi is properly powered up. With a bad power supply it would flash below 4,63 V. So you do not have to worry about your power supply with 1 A output.

If that helps, plug in cables one at a time to identify which is interfering with boot. Confirm the USB cable is properly seated in the power slot. The red power LED does not necessarily mean it is fully connected. The voltage is too low (below 5 V), try a different power supply and/or cable. The R-Pi needs a supply rated for 700 mA or more.
