What it is

The BFKK 5V 2A power adapter converts 100-240V AC mains supply at 50/60Hz into a regulated 5V DC output rated at 2A maximum. It delivers up to 10 watts through a 5.5mm barrel jack compatible with both 2.1mm and 2.5mm centre-pin sizes.

Who it suits

This unit suits devices that specify exactly 5V input and draw 2A or less, such as TV boxes, cameras, speakers, routers, Raspberry Pi boards, USB hubs, LED strips and Bluetooth speakers. It is not for equipment requiring a different voltage, a current draw above 2A, or a barrel connector other than 5.5mm x 2.1mm or 5.5mm x 2.5mm.

What the bundle changes

The adapter ships as a standalone wall charger with no additional cables, tips or mounting hardware included. Buyers must verify that their device uses one of the two supported jack sizes and that its power label matches the 5V 2A rating before connecting.

Questions about this item

Does my device need a 5.5 mm barrel jack with 2.1 mm or 2.5 mm centre pin to use this adapter?

Yes. The plug is 5.5 mm outer diameter and fits centre pins of 2.1 mm or 2.5 mm.

Can I keep using my older 5 V equipment that draws less than 2 A with this supply?

Yes. It delivers 5 V at up to 2 A and will safely power any 5 V load from 0.1 A to 2 A.

How can I confirm the adapter is working after I plug it in?

Connect it to a compatible 5 V device; if the device powers on and operates normally, the adapter is functioning correctly.
