What is the difference between a power adapter and a battery charger?

A power adapter converts AC power from a wall outlet into DC power to operate electronic devices directly. A battery charger is designed to charge batteries using a specific charging algorithm and voltage/current profile.

What connector sizes are available?

Common DC connector options include:

  • 5.5 × 2.1 mm
  • 5.5 × 2.5 mm
  • 4-pin XLR
  • Aviation connectors
  • GX series connectors
  • Anderson connectors
  • Terminal block connections

Custom connectors are also available.

What certifications do your power adapters and chargers have?

Depending on the model, our products can be certified with:

  • UL
  • cUL
  • FCC
  • CE
  • UKCA
  • SAA
  • PSE
  • CB
  • RoHS
  • DOE Level VI

Please contact Guangdong QINX Technology Co., Ltd. for certification details of a specific model.

What is DOE Level VI efficiency?

DOE Level VI is an energy-efficiency standard for external power supplies. It requires lower standby power consumption and higher operating efficiency, helping reduce energy costs and environmental impact.

What protection functions are included?

Typical protections include:

  • Over-voltage protection (OVP)
  • Over-current protection (OCP)
  • Short-circuit protection (SCP)
  • Over-temperature protection (OTP)

Protection features vary by model.
