Template:AC Adapter

☐ Find the input voltage and amperage listed on the laptop. This may be printed on the back of the laptop, or on the chassis under the battery.
☐ Find an AC adapter that matches the voltage and amperage listed on the laptop. You will be looking in the output section printed on the AC adapter:

INPUT: 100-240V~1.9A
       50/60Hz
→ OUTPUT: 16V ⎓ 4.5A 

Requirements

For an AC adapter to power the device correctly, it must:

• Match the input voltage (V) of the laptop exactly.
• Match or exceed the recommended amperage (A).
• Have a plug that fits into the laptop snugly and provides power.

Tip

AC adapters are sorted in bins by voltage, amperage, and brand; the bins are color-coded by brand.
