YACSEJAO USB 5V to 9V/12V Step Up Cable 2.6FT/0.8M USB to 9v, 5v to 12v Step Up Step Up Voltage Converter with DC Jack 5.5 x 2.1mm(3.5 x 1.35mm)

• 【USB to DC Booster Cable】Mainly used for USB to DC, 5V to 9V 12V boost. The cable can only operate with an output voltage of 9V or 12V 800Amh MAX, they are an IC circuit used to limit voltage to protect your device.
• 【Functional Design】Each cable will have an IC circuit to protect your device over load.It helps the cable in steady current&steady voltage,when your output or input is over the limit of the cable,it will lower the current to protect your devices.
• 【Easy to Use】With digital display function, which can provide much convenience for your using and operating. With compact shape, lightweight and portable, take up no space and you can put it anywhere.
• 【Application】The usb to DC 12V/9V cable can be used to power the router via power bank if power down. In addition, can also be applied to other device which is 5v power supply, such as small fan, desk lamp, solar panel, USB power pack, power adapter, speakers that requires for 12V/9V poewr and bluetooth audio etc.
• 【Widely Usage】 Plug and play, It is widely used in 12V low-power equipment such as a wireless router, smart speaker, smart camera, light band, game console, table lamp, breast pump, mini fan, development board,etc.

YACSEJAO 5V to 9V 12V Boost Digital Display Adjustable Power devices such as routers and optical cats through the USB port of the charging bank. Product interface: USB to DC3.5mm/USB to DC5.5mm Interface size: [DC3.5mm interface specification: Outer diameter 3.5mm, inner diameter 1.35mm] [DC5.5mm interface specification: Outer diameter 5.5mm, inner diameter 2.1mm] Plug level: positive inside and negative outside Three kinds of line difference: [5V straight-through] simple power cord, USB input 5V, power supply DC plug output 5V. [9V voltage boost wire] with a booster component, the USB input voltage of 5V through the component to boost to 9V, current within 1A. [12V straight-through] With a booster component, the USB input voltage of 5V is boosted to 12V through the component, and the current is less than 1A. Warm tips: (1) Do not connect the USB power supply port of the 9V/12V booster cable to the USB port on the computer (2) The current output of the 9V/12V booster line is less than 1A. If the current of your router/optical cat is greater than 1A, it cannot be used
