Dell YF-0501 5V 1A AC Adapter

This Dell YF-0501 adapter converts 100-240V AC mains to a regulated 5V DC output at 1A maximum. It terminates in a 5.5mm x 2.5mm barrel connector with centre-positive polarity and includes a 140cm power cord. The unit suits routers, speakers, security cameras and similar low-power 5V equipment.

Safety protections and plug compatibility

Built-in overload, over-voltage, over-temperature and short-circuit cut-offs disconnect the output when limits are exceeded. The 5.5mm x 2.5mm barrel plug also fits devices specified for 5.5mm x 2.1mm centres, reducing the need for a separate adapter tip.

Users needing up to 5W at 5V DC

Buyers whose gear draws 1A or less at 5V and uses the stated barrel size can power it directly. Devices requiring more than 1A, a different voltage, USB-C delivery or a larger barrel diameter will need a different supply.

Questions about this item

How often should I replace the power cord or the adapter itself under normal use?

The adapter has no user-replaceable parts; the 140 cm cord and barrel connector are fixed. Replace the whole unit if the cable jacket cracks, the plug loosens, or the safety cut-offs trip repeatedly.

What limit will I hit first if I run a device drawing close to 1 A continuously?

The 5 W maximum output and the over-temperature cut-off will activate before the 1 A rating is exceeded, shutting the adapter down until it cools.

How warm does the brick get and how much power does it draw from the wall when left on 24/7?

Operating temperature is rated 0–40 °C; at full 5 W load the brick runs warm but stays within that range, drawing roughly 6–7 W from a 100–240 V supply.
