It has a USB A type male input and a 2.1 x 5.5mm output plug with the inside positive pole and outside negative. The cable is approximately 1M\/3Ft long and black. It is intended for 12V devices rated at 600mA or less, with a maximum output power of 6W and a maximum output current of 600mA. Typical source-supported uses include connecting a power bank to a router during a power cut, supplying a car air purifier or LED strip light from a power bank, or powering other 12V devices under 6W. The package contains 1PC of the cable, and other accessories shown in the picture are not included.\u003c\/p\u003e\u003ch2\u003eFeatures and Construction\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Black USB 5V to DC 12V step-up converter cable, 1M, USB A male to 2.1x5.5mm male plug\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US10\/9211\/2025-12-03\/original-image\/163370528580.webp\"\u003e\u003c\/div\u003e\u003cp\u003eThe cable provides a direct link between a USB A type male output and a 2.1 x 5.5mm DC plug. It is a step-up converter cable, not a standard passive USB cable, and it is intended for low-power 12V equipment within the stated 600mA and 6W limits.\u003c\/p\u003e\u003ch3\u003eMaterial and Build\u003c\/h3\u003e\u003cp\u003eThe source text specifies a black cable with a USB A type male input interface and a 2.1 x 5.5mm output plug. The output plug polarity is inside positive and outside negative. These connector details matter because a matching physical fit and correct polarity are required for the connected 12V device. No further material composition, insulation rating, or durability specification is provided in the source text.\u003c\/p\u003e\u003ch3\u003eSize and Practical Fit\u003c\/h3\u003e\u003cp\u003eThe cable length is approximately 1M\/3Ft, which gives a modest reach between a USB power source and a nearby 12V device. The output plug size is 2.1 x 5.5mm, a common DC barrel size, but compatibility should be checked against the device input before purchase. The input is USB A type male, so it fits a standard USB-A female port on a power bank or similar DC 5V USB source.\u003c\/p\u003e\u003ch2\u003eUses and Placement\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Black USB 5V to DC 12V step-up converter cable, 1M, USB A male to 2.1x5.5mm male plug\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US10\/9211\/2025-12-03\/original-image\/2370613338590.webp\"\u003e\u003c\/div\u003e\u003cp\u003eThe cable is suited to temporary or portable 12V power arrangements where a USB power bank is available and the device load is within the stated limits. It does not generate power by itself and depends on a suitable DC 5V USB source.\u003c\/p\u003e\u003ch3\u003eEvent or Professional Use\u003c\/h3\u003e\u003cp\u003eDuring a power cut, this cable can connect a power bank to a router so the router can receive a 12V supply from the power bank. It can also be used to supply a car air purifier or LED strip light from a power bank. In each case, the 12V device must be rated at 600mA or less, and the total output must remain within 6W maximum output power.\u003c\/p\u003e\u003ch3\u003eEveryday Home Use\u003c\/h3\u003e\u003cp\u003eAt home, the cable can link a suitable USB power bank to a compatible 12V device with a 2.1 x 5.5mm input. It is useful where a mains 12V adapter is not available or where a portable 5V USB source is already on hand. The approximately 1M\/3Ft length allows the power bank and device to sit near each other without excessive cable slack.\u003c\/p\u003e\u003ch2\u003eBenefits and Buying Value\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Black USB 5V to DC 12V step-up converter cable, 1M, USB A male to 2.1x5.5mm male plug\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US10\/9211\/2025-12-03\/original-image\/5690205294.webp\"\u003e\u003c\/div\u003e\u003cp\u003eThe practical value lies in adapting a DC 5V USB output to a DC 12V device within a clearly stated low-power range. Because the cable is reusable, it can remain part of a emergency or portable power kit.\u003c\/p\u003e\u003ch3\u003eReuse and Low Maintenance\u003c\/h3\u003e\u003cp\u003eThe cable can be kept with a power bank and reused whenever a compatible 12V device needs a temporary supply. No cleaning, service, or maintenance instructions are provided in the source text. Store it dry and check the connectors and cable before each use, particularly if it has been bent or strained.\u003c\/p\u003e\u003ch3\u003eWhy Choose This Product\u003c\/h3\u003e\u003cp\u003eChoose this cable when you need a USB A male to 2.1 x 5.5mm male step-up connection for a 12V device rated at 600mA or less and no more than 6W.
