Choosing the appropriate ITE (Information Technology Equipment) power adapter is essential to ensure device compatibility, safety, and long-term stability. Here are the key factors you should consider when selecting an ITE power adapter:
1. Confirm the Output Voltage and Current
Ensure the power adapter’s output voltage (V) and output current (A) match your device’s requirements.
✅ For example:
If your device needs 12V/2A, use a 12V adapter with at least 2A output.
Tip: It’s okay to choose an adapter with a slightly higher current rating than needed, but never lower.
2. Check the Connector Type and Polarity
Different devices use different DC plugs or barrel connectors. Always verify:
Outer/inner diameter (e.g., 5.5mm/2.1mm)
Polarity (center-positive or center-negative)
Locking, USB, or custom connectors
Quankang supports custom connectors to match your device perfectly.
3. Evaluate Power Rating (Watts)
Multiply voltage × current to determine the wattage. Make sure the adapter’s power rating (W) is equal to or higher than your device’s requirement.
Example:
12V × 3A = 36W, so use a 36W or higher-rated adapter.
4. Consider Efficiency Standards
For commercial and international use, adapters must meet energy efficiency regulations, such as:
✅ DoE Level VI (U.S.)
✅ ErP Lot 7 (Europe)
✅ CoC Tier 2
Quankang’s ITE power adapters are certified for global efficiency standards.
5. Global Safety Certifications
Always choose a power adapter with valid safety approvals for your target market:
UL / FCC – North America
CE / GS / UKCA – Europe
PSE – Japan
CCC – China
KC – Korea
All our adapters are compliant with international safety standards.
6. Application Environment
Will the adapter be used in:
If so, look for:
7. Mounting & Form Factor
Choose between:
Wall-mount adapters (direct plug-in, compact)
Desktop adapters (with AC cable, larger output power)
USB-PD or programmable types (for smart devices)
8. Custom Branding and OEM Support
For companies reselling or integrating the adapters, look for:
Custom logo/labeling
Unique housing design
Package design support
