Replacement Dell Inspiron Duo 1090 AC Adapter, guaranteed compatible with 1-year warranty. This is a new, Delta original product.
Dell Inspiron Duo 1090 Power Supply Specs:
When ordering a Dell Inspiron Duo 1090 AC adapter, check the voltage and amperage on the bottom of the netbook to make sure you are ordering the correct AC adapter. Some models have more than one AC adapter depending on the amperage rating. The rating should be taken from the netbook, not the AC adapter because this is the best match of what the netbook needs. You should find a rating that looks like this: 19V --- 1.58A. It can be on the label on the bottom of the netbook or in the battery compartment. AC adapters are safe to use within +/- 1V of the netbook voltage. It is also safe to have a higher amperage than marked on the netbook becuase the netbook can only pull the amperage it needs. Less than the required amperage will cause the power supply to burn up because the netbook is pulling more amperage than the AC adapter can give it. Also, check the DC Jack on the back of the netbook to make sure it is not loose. This will cause the netbook to appear like the AC adapter is bad when the netbook is just not making connection with power.
