If there’s any doubt at all, it’s better to err on the side of caution and be sure.
3. Match Your Volts & Amps
You always wants to match the Voltage and Amperage of your current Sony VGP-AC19V19 AC Adapter. If you have higher amperage with matching voltage, you can still use it. The general rule of thumb, however, is to not use any adapter with over 2x the amperage.
Example:
– I have a 60W AC adapter and want to use a 90W adapter? YES
– I have a 60W AC adapter and want to use a 150W adapter? NO (not recommended)
