No, you should always match the voltage requirements. Not only will your battery not charge you could actually damage it.
Your laptop is unable to charge because of a problem with your adapter or the battery itself; try plugging out the battery and returning.
DELL AC Adapters are manufactured with ID chips. The Laptop communicates with the AC adapter to find out the type and power rating. When the AC power adapter doesn't answer it doesn't charge the laptop battery. See the related link below for a full explanation of the problem.
If the adapter has the correct voltage, connector type and polarity, there should be no problem. The 65W and the 120W is the number of watts of power the adapter can provide. If the laptop needs 65W and the adapter can supply 120W, it should work fine. Had it been the other way around, the adapter might not be able to supply enough power for the laptop and it might get too hot and burn out.

Using a laptop AC adapter with a higher amperage rating should be safe, as the laptop will only draw the amount of current it needs. However, using an adapter with a much higher voltage could damage your laptop. Always match the voltage and polarity exactly, and ensure the amperage is equal to or higher than the original adapter.
To charge your Toshiba laptop, you'll need the appropriate power adapter that matches your laptop model. Plug the adapter into a power outlet and connect the other end to your laptop's charging port. Ensure the connection is secure and check for any indicator lights to confirm that the laptop is charging. If your laptop has a removable battery, make sure it is properly installed.

It sounds like you are referring to a universal adapter. A universal ac adaptor has several tips, which adjust the voltage and amperage, and the higher the voltage, the lower the amperage. Therefore, if your adapter is 4.3 amps at 15 volts, it will be significantly lower amperage at 19 volts.
It is not recommended to use a 16V charger with an 18.5V laptop. The voltage difference may not provide enough power for the laptop to operate properly or could potentially damage the laptop's components. It is best to use a charger that matches the voltage and current requirements specified by the laptop manufacturer to ensure safe and optimal performance.
