This cable features an integrated boost converter, enabling it to draw power from any USB port—be it from a computer, battery pack, or other USB sources—and output a higher DC voltage. Ideal for powering 12V devices with a center-positive DC barrel jack from a USB source, it adds convenience to your power supply needs.The DC barrel plug sports a standard 2.1mm opening, complete with springs for the center terminal, making it compatible with 2.1mm jacks. Rated at a 500mA output, this cable also supports higher current draws; it has been tested with up to 700mA with minimal voltage droop. However, continual operation at 700mA is not recommended.Efficiency metrics include 83% efficiency at 150mA draw and 86% efficiency at 200mA draw, with an overall efficiency averaging around 85% at low currents, decreasing to about 80% at higher currents. The cable also features a low quiescent current of 3mA. Additionally, be wary of potential USB port voltage droop and resistivity issues in low-quality cables. https://elecena.pl/product/29465140/adafruit-usb-to-5-5mm-2-1mm-dc-booster-cable-12v-output 2025-10-30 https://elecena.pl/product/29465140/adafruit-usb-to-5-5mm-2-1mm-dc-booster-cable-12v-output 2025-11-04 https://elecena.pl/product/29465140/adafruit-usb-to-5-5mm-2-1mm-dc-booster-cable-12v-output 2025-12-04 https://elecena.pl/product/29465140/adafruit-usb-to-5-5mm-2-1mm-dc-booster-cable-12v-output 2025-12-15 https://elecena.pl/product/29465140/adafruit-usb-to-5-5mm-2-1mm-dc-booster-cable-12v-output 2025-12-20 https://elecena.pl/product/29465140/adafruit-usb-to-5-5mm-2-1mm-dc-booster-cable-12v-output 2025-12-26 https://elecena.pl/product/29465140/adafruit-usb-to-5-5mm-2-1mm-dc-booster-cable-12v-output 2025-12-31 https://elecena.pl/product/29465140/adafruit-usb-to-5-5mm-2-1mm-dc-booster-cable-12v-output 2026-01-22 https://elecena.pl/product/29465140/adafruit-usb-to-5-5mm-2-1mm-dc-booster-cable-12v-output 2026-01-24 https://elecena.pl/product/29465140/adafruit-usb-to-5-5mm-2-1mm-dc-booster-cable-12v-output 2026-01-30 https://elecena.pl/product/29465140/adafruit-usb-to-5-5mm-2-1mm-dc-booster-cable-12v-output 2026-02-20 https://elecena.pl/product/29465140/adafruit-usb-to-5-5mm-2-1mm-dc-booster-cable-12v-output 2026-02-23 https://elecena.pl/product/29465140/adafruit-usb-to-5-5mm-2-1mm-dc-booster-cable-12v-output 2026-03-04 https://elecena.pl/product/29465140/adafruit-usb-to-5-5mm-2-1mm-dc-booster-cable-12v-output 2026-04-12 https://elecena.pl/product/29465140/adafruit-usb-to-5-5mm-2-1mm-dc-booster-cable-12v-output 2026-06-22 https://elecena.pl/product/29465140/adafruit-usb-to-5-5mm-2-1mm-dc-booster-cable-12v-output 2026-06-29
