LM2596 No-isolation DC-DC Converter Power Supply Module IN 4-35V OUT 1.25-30V 3A | eBay

won this on bidding $4.99 only person that bid (wonder why )
all it is is a LM2596 in a very small project box, not much bigger than the
2596. Will just make a mod with 2-18350's in it without the board.

Just put a atty connector, switch, and 2.1mm plug and you have a PT in a small box.
