I have designed, built, and tested an all-HF WSPR beacon that produces 1W @ 5V and is rugged and cost-effective.
Results
Power consumption: Around 420mA @ 5V.
Cost
Cost: Around 500 INR.
Time to build
Time to build: Less than 30 minutes.

The files for this project are published here for personal (non-commercial) use.
For a 5W (QRO) WSPR beacon, please stay tuned for our upcoming QEX magazine article ;)
Special shout-out goes to Brad (K1TE) for always pushing me to do better.
Updates
Updated PCB design (more compact):
I plan to use the following Panel Mount USB Type C Female Connector Jack - JST-PH-2.0 Connector Output in this project. The JST-PH connector on the PCB may need to be flipped to ensure correct polarity.
