How to Find Compact Dell Inspiron 1420 AC Adapter

For Dell Inspiron 1420 AC Adapter information, you should also know some knowledge about how to replace a missing or broken Dell ac adapter.

They must both be the same type with respect to laptop ac adapters or DC adapter. (In rare instances, either will work but this is the exception and there is no way to know without examining the circuit unless this capability is explicitly stated on the device or in the user manual.)

If DC, the polarity must be the same. Even if the connectors are identical, it's a coin toss as to whether the center is positive or negative. However, the Dell laptop ac adapter cable can be cut and spliced if incorrect polarity is the only problem. The Dell Inspiron 1420 AC Adapter replacement much have at least the same current rating. Higher current is fine as long as it isn't ridiculously more.

The connectors should be identical. If the old Dell AC Adapter is dead, and it's not a cable problem near the connector, cutting and splicing in the old connector on the new Dell Inspiron 1420 AC Adapter is acceptable as long as it's done very carefully and double checked for wiring errors and short circuits.

The output voltage with no load must not be much greater than the listed value unless you know for sure that the equipment can take it, or that the other laptop ac adapter behaved similarly.

The replacement doesn't need to be switchmode unless weight is an issue, but it must be regulated.

For some reason I've been fascinated by tiny laptop AC adapter that use switch mode power supplies, since they're light and can supply more current than similar linear power cubes. One type that keeps catching my eye is used a lot for "AC travel charger" accessories. These things connect via a cable to the bottom of a laptop, much like the cigarette-lighter "charger/saver" accessories, only the Dell Inspiron 1420 AC Adapter driven by house current.
