Purpose and audience
This 12 V 0.5 A AC adapter powers low-draw devices such as CCTV cameras, LED strip lights, USB hubs, Bluetooth speakers, wireless routers, mini fountains and Wi-Fi IP cameras. It accepts a universal 100–240 V 50/60 Hz mains input and delivers up to 6 W of regulated DC power. The unit is not a charger and cannot supply more than 0.5 A.
Critical specification
The barrel plug measures 5.5 mm outer by 2.5 mm inner and is centre-positive; it also fits 5.5 mm × 2.1 mm sockets. Polarity and dimensions must match the target device exactly, otherwise the adapter will not connect or could cause damage.
Included accessories and effect
A fixed mains lead approximately 3 ft long is integrated into the body, so no separate cable is required. The flame-retardant enclosure is rated to withstand 1382 °C and the adapter carries FCC, CE, RoHS and CCC certifications with over-current, over-voltage, overload and short-circuit protection built in.

Questions about this item
What does the 6 W output rating mean for a device I connect?
The adapter can supply up to 6 W at 12 V, so it will power any 12 V device that draws 0.5 A or less — for example a 12 V LED strip, a small IP camera or a USB hub rated at 6 W or below.
What does the 5.5 × 2.5 mm centre-positive plug mean for compatibility?
The barrel connector has a 5.5 mm outer diameter and a 2.5 mm inner pin with positive voltage on the centre; it also fits sockets made for a 2.1 mm pin, so it works with most common 12 V DC jacks that use this polarity.
How much clearance does the 3 ft power cord need behind my equipment?
The cord is about 3 ft long, so you need roughly that much free length from the wall socket to the device plus a little slack for routing; the adapter body itself is small enough to sit on a desk or tuck behind a rack without extra mounting hardware.
