Oh yeah, the D1 Mini also has a very low quiescent current (25uA) RT9013 regulator, so it should be much better for use on battery power than the nodemcu with the LM1117 which uses 5mA! That's 200x less current wasted!
Also the dropout voltage is only 250mV compared to about 1V for the LM1117. You couldn't use a LiPoly battery to power it with an LM1117 because of the high dropout voltage.
