This Manw power adapter delivers a regulated 12 V output at 4 A for a total of 48 W. It suits LCD monitors, LED strip lights and other low-voltage devices that match the specified plug. The wide 100–240 V 50/60 Hz input lets it operate on mains supplies worldwide.

IC Chip Board and Four Protection Layers

An IC chip motherboard solution and high-quality components provide stable output under load. Over-voltage, over-current, short-circuit and over-heat protections guard connected equipment. Every unit undergoes a load aging test before shipment.

5.5×2.1 mm Nickel-Plated Plug and 90 cm Cable

The all-copper nickel-plated DC connector has a 2.5 mm inner diameter and 5.5 mm outer diameter. Its 90 cm (2.95 ft) lead resists wear and corrosion through repeated insertion cycles. The package includes the adapter and an AC power cable; buyers needing a different plug size or longer reach must source an alternative.

Questions about this item

Will the 5.5 mm by 2.1 mm DC plug or the 90 cm cable need replacement first under normal use?

The plug is nickel-plated copper and tested for repeated insertion cycles, while the 90 cm cable is fixed; the connector typically outlasts the cable if strain relief is respected.

What limit appears first when the adapter runs continuously at 48 W output?

The over-heat protection engages before the 4 A current limit is exceeded, shutting the unit down until it cools.

How much heat and fan noise should I expect when this adapter powers a load all day?

There is no fan; the unit relies on passive convection, so it runs silent and warm but stays within safe limits thanks to the over-heat protection circuit.
