SparkFun Barrel Jack to 2-pin JST Adapter Cable Pogo Pins "Spear Head" (10 pack) - P75-LM3 SPI chip select connected toTwo 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!
