Black rectangular AC/DC adapter with 5.5 by 2.5 mm barrel plug and 90 cm cord

DYMATIZE

DYMATIZE 4.5V 1A AC/DC Adapter 5.5x2.5mm Plug

SKU CH-VN5V-GZ1KX

Supplies 4.5 V at 1 A through a 5.5 × 2.5 mm plug with 90 cm cable and built-in overload protection

  • Accessory TypeAC Adapters
  • Delivers stable 4.5V power from 100-240V input
  • 0A output supports devices drawing up to 1000mA
  • 5 x 2.5 mm plug with centre-positive polarity
  • Built-in overload, over-voltage, thermal and short-circuit protection
  • 90 cm copper cable with ferrite ring reduces interference

Power Adapter Purpose

The DYMATIZE AC to DC adapter converts 100 to 240 V mains electricity into a regulated 4.5 V direct current at up to 1.0 A. It is designed for devices such as set-top boxes, routers, game consoles, repeaters, mini speakers, headphones, security equipment, LED lamps and similar low-power electronics that require this exact voltage and connector size.

Cable and Protection Features

A 90 cm cord uses copper cores and terminates in a 5.5 x 2.5 mm barrel plug with centre-positive polarity and an integrated ferrite ring to suppress noise. Built-in safeguards include automatic overload cut-off, over-voltage cut-off, thermal cut-off and short-circuit protection, and the supplier advises operating below 80 per cent of the rated 4.5 W maximum load.

Connector and Voltage Constraints

The fixed 4.5 V output and 5.5 mm by 2.5 mm plug dimensions mean the unit cannot power equipment that requires a different voltage, current rating, polarity or barrel size. Buyers who need a higher wattage supply, a longer cable or an alternative connector type must select a different adapter.

Highlights

Questions about this item

Will the 5.5 × 2.5 mm barrel plug or the 90 cm cable need replacing first?

The cable is a fixed 90 cm length with a copper core and ferrite ring; the barrel plug is moulded on. Neither is designed for user replacement, so plan to replace the whole adapter if either fails.

What stops the adapter from delivering its 4.5 V 1 A output continuously?

Built-in overload, over-voltage and thermal cut-offs will shut the unit down if the load exceeds about 80 % of the 1 A rating or if internal temperature rises too high.

How hot or noisy does the adapter get when left running 24/7?

The adapter is a sealed switching supply with no fan; it runs silently and the thermal cut-off limits case temperature, but no specific surface-temperature figure is published.
