According to http://www.ebay.com/itm/nRF24L01-Wireless-Transceiver-Module-PA-SMA-Antenna-MAX-distance-up-to-1KM-/160822596423?pt=LH_DefaultDomain_0&hash=item2571c61347 the max current for thr amplified radio is 115ma. According to https://github.com/nodemcu/nodemcu-devkit the nodemcu can supply at least 500ma on 3.3V. So unless you connect a lot of other power hungry stuff you should be fine.
