Compact 5 V 1 A power adapter
The Phihong PSAC05R-050 is a 5 W AC adapter that delivers 5 V at 1 A through a Mini-USB connector. It accepts a universal 100-240 V input at 50-60 Hz, making it suitable for worldwide mains supplies. The unit is supplied new and includes built-in protection against incorrect voltage, short circuit and internal overheating.
For devices needing 5 V Mini-USB power
This adapter suits hardware that draws up to 1 A at 5 V and uses a Mini-USB input, such as certain routers, hubs or legacy peripherals. It is not for equipment that requires a higher voltage, a larger current or a different connector type such as Micro-USB, USB-C or a barrel jack. Buyers needing more than 5 W should look at a higher-rated supply.
Check voltage, current and plug before ordering
Confirm the target device specifies exactly 5 V DC and a maximum draw of 1 A or less. Verify the power port is Mini-USB and that the polarity matches the adapter output. Ensure the mains socket provides 100-240 V AC at 50-60 Hz, which covers most domestic supplies.

Questions about this item
What device with a Mini-USB port needs 5V 1A power to run with this adapter?
Any device that draws up to 1A at 5V through a Mini-USB connector — such as certain routers, external drives or development boards — will work with the 5W output.
Can I keep using my existing IEC C7 figure-8 mains lead with the 100-240V~300mA 50-60Hz input?
The adapter has a fixed mains plug, so a separate IEC C7 lead is not used; plug the unit directly into a 100-240V socket.
How do I confirm the 5V 1A output is live after connecting the Mini-USB cable?
Measure 5V at the Mini-USB plug with a multimeter, or verify the attached device powers up and operates normally.
