USB step-up converter with DC 5.5x2.1mm plug - 5V to 12V 1A

USB DC 12V step-up converter for Arduino

The USB to DC 5.5x2.1mm / 2.5mm step-up adapter is an ideal solution for powering devices with a DC jack directly from a computer USB port, a power bank, or a phone charger. It enables charging and powering equipment fitted with a DC 5.5x2.1mm or 5.5x2.5mm jack from a universal USB type A port.

The DC plug has a 2.5mm pin, which ensures compatibility with both socket standards. It is an extremely practical tool for powering electronic modules, including for Arduino, from USB 5V or connecting power via a USB-A port from a DC power supply.

Key technical specifications
