This simple cable has so many uses! Plug the 9 volt battery clip onto a standard 9V battery and connect the other end to anything with a 5.5x2.1mm, center-positive barrel jack. Use this cable to battery-power any device that needs 9V and has an on-board barrel jack - it works great for Arduinos, development boards, evaluation boards, and more! ...

This is a simple cable that adapts from a USB port to a 5.5x2.1mm barrel connector, center positive. This cable allows the user to use a USB port on a computer, laptop, or on our cigarette power supply to provide our development boards with 5V. The USB specification limits current consumption to a max of 500mA from a USB port but this is more than enough to run a simple development board. Cable length is 3 feet.

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!

This is a high grade DC Buck converter that inputs 6 to 12V and outputs 5V up to 3A or 15W. With good thermal performance and protection, this DC block is perfect for battery applications (such as...

This is a high grade DC Buck converter that inputs 6 to 12V and outputs 5V up to 3A or 15W. With good thermal performance and protection, this DC block is perfect for battery applications (such as SLAs or LFPs) that need to power a USB or 5V device even while the input is varying (battery charge/discharge). 89% efficiency makes this a high-efficiency, plug and play, DC Step Down solution. Features: Input Voltage: 6 to 20VDC Input Current: 3ADC max Quiescent Current: 12.5mA Efficiency:...

This is an industrial grade DC Buck-Boost converter that inputs 8V to 40V and outputs 12V up to 3A or 36W. With tons of heatsinking and protection, this DC block is perfect for battery applications...

This is an industrial grade DC Buck-Boost converter that inputs 8V to 40V and outputs 12V up to 3A or 36W. With tons of heatsinking and protection, this DC block is perfect for battery applications (such as SLAs or LFPs) that need to power a steady load (such as 12V router and WiFi equipment) even while the input is varying (battery charge/discharge). 85% efficiency makes this a good, plug and play, DC Step-Up/Down solution. Features: Input Voltage: 8 to 40VDC Input Current: 1 to...
