Universal AC adapter for low-voltage devices

This WAWEIS AC adapter converts worldwide mains input of 100-240VAC at 50/60Hz into a selectable 3V-3.3V output at 2A-2.5A. The barrel connector measures 5.5mm x 2.1mm and the integrated power cord extends 6.5 ft. Safety circuitry includes over-current, over-voltage, short-circuit and total power protection, backed by FCC, CE and RoHS certification.

Suits owners of legacy

Buyers replacing a lost or faulty charger for routers, switches, audio gear or older laptops that specify 3V-3.3V at 2A-2.5A will find a direct match. It is not for devices that require a different fixed voltage, a higher current rating, a USB-C power delivery profile or a proprietary multi-pin connector.

Output fixed at 3V-3.3V 2A-2.5A on a 5.5mm x 2.1mm

The single specification that decides fit is the regulated output window of 3V-3.3V at up to 2.5A delivered through the stated barrel size. Verify the target device's label matches this voltage range, current demand and connector polarity before purchase.

Questions about this item

Will the 5.5 mm × 2.1 mm barrel connector wear out and need replacing?

The barrel connector is a standard 5.5 mm × 2.1 mm size; if it loosens over time you can replace the adapter with any unit that matches the 3 V–3.3 V and 2 A–2.5 A output range.

What stops the adapter from delivering more than 2.5 A during a long charge session?

Built-in over-current protection and total-power protection limit the output to the rated 2 A–2.5 A range even under sustained load.

How warm does the brick get when it runs all day at 100–240 VAC?

Over-heating protection with a smart chip and overload protection keep the brick at a safe temperature during continuous 24-hour operation.
