using a 10W( 5v~2A) power adapter for raspberry pi 4

Fri Aug 30, 2019 8:26 am

I am using a 10W power adapter to power up my raspberry pi 4.The red and green LED's blink at start. (The green LED gets dimmer after about 20 seconds and red. ).I don't have a monitor with a HDMI port so that I can actually see if my pi is working fine.I tried to set up SSH through
"putty" (a software to set it up easily) but It didn't work. The only thing I feel that's going wrong is the power supply. the raspberry pi 4 documentation says that a minimum of 3A is required but my power adapter supplies 2A at 5V -~10W. should I buy the official 15.3W power adapter?

also the chips on board get really hot just after minutes of powering it up.

Heat is expected. It may be underpowered, but I would expect it to boot with 10W. You really need to be able to access either the HDMI or the logs to see whether it is getting undervoltage events.
