Black rectangular AC adapter with 5.5mm x 2.1mm barrel plug and 6.5ft power cord

WAWEIS

WAWEIS AC/DC adapter 5.5mm x 2.1mm 3.3V 1A 6.5ft cord

SKU CH-HHX0-CZC3R

A 3.3V 1A AC/DC adapter with a 5.5mm x 2.1mm tip, 6.5ft cord and 100-240V input

  • World-wide 100-240 VAC input for universal use
  • 5 ft cord gives flexible placement
  • 3 V 1 A output matches device requirements
  • FCC CE RoHS certified for safety compliance
  • Over-current over-voltage short-circuit protection included

What this adapter powers

This WAWEIS AC/DC adapter delivers 3.3 volts at 1 amp through a 5.5 mm by 2.1 mm barrel connector. It accepts worldwide mains input from 100 to 240 volts at 50 or 60 Hz and includes a 6.5 ft power cord for flexible placement. The unit is new and built to FCC, CE and RoHS standards.

Replacing a lost or faulty charger

It replaces an original laptop or device charger that uses the same 3.3 volt, 1 amp output and identical 5.5 mm by 2.1 mm tip polarity. The upgrade is worth it when the original supply is missing, damaged or no longer holds a stable voltage under load. Built-in over-current, over-voltage, short-circuit and total-power protection guards the connected device during the swap.

Behaviour under continuous use

The adapter maintains its rated 3.3 volt output during sustained operation thanks to overload protection, high-quality wiring and a smart chip that manages overheating. Anti-interference isolation materials keep the output clean over long sessions. Safety certifications confirm the protection circuits remain effective after extended duty cycles.

Questions about this item

What plug size does the 3.3V adapter use for the device connection?

The adapter uses a 5.5mm outer diameter and 2.1mm inner diameter barrel connector for the DC output.

How do I connect the 6.5ft power cord to the mains supply?

Plug the IEC C7 figure-8 mains lead into the adapter brick, then insert the wall plug into a 100-240VAC 50/60Hz socket.

When should the AC adapter be replaced?

Replace the unit if the output voltage drifts from 3.3V, the 1A current limit trips repeatedly, or the 6.5ft cord shows insulation damage.
