LoRa still needs about 100mW when transmitting, which is a thousand times more than what this can do…

Yes I’m talking about recharging a battery sitting next to this; agreed that it can’t power a node directly. In the U.K. we are actually allowed to transmit up to 500 mW on the ISM band (provided we adhere to the utilisation quota, which I think is 15%)
