Dell 81407 70-Watts 20V 3.5A Power Adapter

Description

The Dell 81407 is a 70-Watt AC power adapter, designed to supply power to compatible Dell laptop computers and potentially other Dell peripherals. It converts AC power from a wall outlet into the DC power required by the device, typically operating at a voltage of 20V with an amperage rating of 3.5A. This combination results in the total power output of 70 watts (20V * 3.5A = 70W), which is sufficient for most mainstream laptops, allowing them to run and charge their batteries simultaneously. This power adapter usually features a specific barrel-style connector that mates with the power input port on the Dell laptop. It's important to ensure compatibility, as different Dell models may use different connector sizes or voltage/amperage requirements. The adapter typically comes with a detachable AC power cord that connects the adapter brick to the wall outlet. The brick itself often includes an LED indicator to show that it is receiving power. Using a genuine Dell power adapter like the 81407 ensures that the device receives the correct and stable power it needs, protecting the battery and internal components from damage caused by incorrect voltage or current. It serves as a replacement for a lost or damaged adapter or as a convenient spare to keep at home or in the office.
