Frequently Asked Questions (FAQ)

Q: Can I use this adapter with a device that requires less than 1000mA (e.g., 300mA or 600mA)?
A: Yes. The 1000mA rating is the maximum capacity. Your device will only draw the amperage it requires, making this adapter fully safe for devices needing 1000mA or less.

Q: How do I select the correct polarity for my device?
A: Check your device or original power supply for a polarity symbol (+ ---C--- -). To change polarity on the PHC-1000K, simply align the tip’s polarity indicator (+ or -) with the arrow on the cable connector prior to plugging it in.

Q: Is this power supply regulated?
A: Yes. Unlike older unregulated transformer supplies that spike in voltage when unloaded, this switching regulated adapter maintains a constant, safe voltage output regardless of the load.

⚠️ IMPORTANT: Always verify your device’s required voltage, tip dimension, and polarity (+/-) prior to connecting. Applying incorrect voltage or polarity can cause damage to your device or adapter. If you need assistance verifying compatibility, please contact our support team.
