Some ESP’s are certainly recorded at > 320mA on boot up even though many will run around 70mA.
Boot up is important so it’s worth trying something that can give you at least 500mA.

here it’s a bit cheaper.
BTW, connect it to the USB power pin on arduino (5.2v) instead of regulated 5v…
“ESP-01 Adatper” 
I’ve set wrong fuses on atmega, so it was running at 8mhz, and IDE compiled code for 16mhz, thus serial wasn’t working. But still, i can’t get it to connect
it just stays at wifi connected.
