Compact 5 V 4 A adapter for USB hubs
This Manw power adapter delivers 5 V at 4 A through a 3.5 mm by 1.35 mm barrel connector, matching the small jack found on many USB hubs. It accepts a 100 to 240 V input, making it suitable for worldwide use. The unit is rated for a maximum of 20 W continuous output. It is intended for hubs and similar peripherals that require this exact voltage, current and connector size.
Steady 20 W output under sustained load
The adapter maintains its rated 5 V 4 A output during extended operation rather than only in short bursts. Continuous 20 W delivery keeps connected hubs stable when multiple devices draw power simultaneously. No internal fan is present, so airflow around the case affects thermal performance. Users needing higher wattage or a different connector diameter should select another model.

Questions about this item
How much heat or noise does the adapter produce when running a USB hub all day?
The unit has no fan and no moving parts, so it runs silently; typical wall-wart warmth is the only noticeable heat.
Does my USB hub need a specific barrel size to work with this 3.5 mm × 1.35 mm connector?
Yes — the hub must accept a 3.5 mm outer-diameter, 1.35 mm inner-diameter male barrel plug with centre-positive polarity.
