Black rectangular power adapter with 1.5 m cable and 5.5 mm x 2.1 mm barrel connector

BFKK

BFKK PA100 5V 2A power adapter 5.5 mm x 2.1 mm 1.5 m

SKU CH-A87A-SWCEF MPN PA100

Supplies 5 V at 2 A to Cisco SPA-series IP phones via a 5.5 mm × 2.1 mm barrel connector on a 1.5 m lead

  • Powers Cisco SPA IP phones reliably
  • Delivers 5 V at 2 A from 100-240 V input
  • Built-in short-circuit, over-voltage, over-current and over-temperature protection
  • FCC, CE and ROHS certified for safety
  • 5 m cable with 5.5 mm x 2.1 mm connector

Compatible Cisco IP Phone Models

This 5 V 2 A power adapter replaces the original Cisco PA100 charger for SPA300, SPA500, CP500 and SPA900 series phones. It supports models such as SPA504G, SPA303, SPA922, SPA942, SPA525G2, SPA962, SPA501G, SPA508G, SPA509G, SPA512G and SPA514G.

Installation and Common Issues

The barrel connector measures 5.5 mm by 2.1 mm and the cord is 1.5 m long, so it reaches most desk outlets without strain. The unit accepts 100-240 V at 50/60 Hz, making it usable worldwide with a suitable plug adapter. Failures usually come from bent centre pins or cracked strain relief rather than the adapter itself.

Practical Limits of the 5 V 2 A Barrel Interface

Output is fixed at 5 V with a maximum of 2 A, delivering up to 10 W; it will not power devices that need higher voltage or current. The connector polarity is centre-positive, so reversing it can damage the phone. The cable is not detachable, so a damaged lead means replacing the whole adapter.

Questions about this item

How can I confirm the adapter is working correctly after plugging it into my Cisco IP phone?

The phone should power on normally and show its usual boot sequence or home screen, indicating the 5V 2A output is stable and the 5.5 mm x 2.1 mm connector is making proper contact.

What comes in the box and do I need to buy any extra cables or plugs for a Cisco SPA504G?

The package includes the PA100 adapter unit with its fixed 1.5 m cable and 5.5 mm x 2.1 mm barrel plug; no additional cables are required for the listed Cisco SPA models.

My Cisco phone needs 5V 1A — is the PA100 rated at 5V 2A safe to use?

Yes, the 5V 2A rating means it can supply up to 2000 mA; it will safely deliver only the 1000 mA your device draws and is explicitly noted as compatible with 5V 1A, 1.5 A and 1.75 A units.
