Barrel Jack to 2-pin JST
Two pin JST connector to a 2.1x 5.5mm barrel jack, 6.25 inch long jumper cable.
We use this cable to adapt from a wall power supply to a relatively small, SMD JST connector.
We found that many of the SMD connectors used for battery charging were too
large or were not capable of through-putting the current we wanted for faster charging.
This setup, with a SMD JST connector and wall power supply, can handle up to 2A!
