The unit accepts 100-240V AC mains input at 50\/60Hz, making it compatible with UK and international mains when paired with an appropriate socket adaptor.\u003c\/p\u003e\n\u003cp\u003eDesigned for powering small electronics that require switchable voltage — routers, CCTV cameras, USB hubs, audio equipment, LED controllers — the Mercury adaptor replaces multiple fixed-voltage wall warts with a single unit. The voltage selector dial on the housing allows switching between seven output levels (3V, 4.5V, 5V, 6V, 7.5V, 9V, 12V) without needing separate adaptors for each device. The eight included DC plugs cover the most common barrel jack sizes used in consumer electronics.\u003c\/p\u003e\n\u003cp\u003eThe switch-mode topology converts mains voltage more efficiently than linear transformers, reducing heat generation and idle power consumption. At 75 x 50 x 42mm and 120g the unit is compact enough for desk drawers, tool kits and travel bags. The moulded UK plug folds flat against the housing when not in use, and the detachable DC cable allows the plug head to be swapped without re-wiring.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower max.\u003c\/td\u003e\n\u003ctd\u003e12W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAdaptor plugs\u003c\/td\u003e\n\u003ctd\u003e3.5mm jack, 2.35 x 0.75mm, 3.5 x 1.35mm, 4 x 1.7mm, 5 x 2.1mm, 5.5 x 2.1mm, 5.5 x 2.5mm, 6.3 x 3mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput voltage\u003c\/td\u003e\n\u003ctd\u003e100-240Vac, 50\/60Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput current max.\u003c\/td\u003e\n\u003ctd\u003e1000mA (all output voltages)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput voltage\u003c\/td\u003e\n\u003ctd\u003e3\/4.5\/5\/6\/7.5\/9\/12Vdc\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e75 x 50 x 42mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e120g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch5\u003eDownloads\u003c\/h5\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/661401UK.pdf\" target=\"_blank\"\u003eProduct Manual\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eWhat devices does this power supply suit?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eAny device requiring 3-12V DC at 1000mA or less, including routers, CCTV cameras, USB hubs, LED strip controllers, small audio equipment, and other consumer electronics.
