Compatible Dell Inspiron 15 3878 charger

This AC adapter replaces the original power supply for Dell Inspiron 15 3878, I5-3878 and 153878 models including the Touch 2-in-1 variant. It delivers a 19.5 V output through a 4.5 mm by 2.7 mm barrel tip that matches the laptop's charging port. The unit is brand new and includes the mains power cord.

Check tip size and voltage before ordering

Verify that your laptop requires a 19.5 V supply and uses the 4.5 mm by 2.7 mm connector; other Dell models may look similar but use different tip dimensions or voltages. Confirm the machine is one of the listed Inspiron 15 3878 series part numbers to avoid a mismatch. The adapter accepts 100 to 240 VAC at 50 or 60 Hz for worldwide use.

Fits directly into existing power setup

The adapter plugs into any standard wall outlet and connects to the laptop without extra cables or converters. Built-in over-voltage, over-current and short-circuit protection safeguards the system during charging. It frees you from hunting for a proprietary Dell brick and restores full mobility to the 2-in-1 device.
