Most of us tend to misplace our Laptop chargers or forgot to pack them up. In such situations, we might have to use chargers with different power and voltage ratings. However, most of us have not thought about the long-term effects of using chargers with different power wattages.

There are 2 different scenarios-higher wattage charger and a lower wattage one. Using a higher wattage charger is perfectly safe. This is because the Laptop is designed in such a way as there is the maximum power that can be drawn by the system. A higher wattage charger can supply this power easily and hence you won’t run into any issues.

A lower wattage charger is a different issue. It is not ideal to use a lower wattage charger. As a result, we would recommend not to use one at all. What makes a lower wattage charger unsuitable for use?

Using such a charger might result in a fuse in energy supply and this could in fact damage other elements of the device. The battery life would be diminished and it would start draining rapidly.

Many users have also reported about the adapter and the laptop overheating. Overheating could cause further performance issues and could damage other components.

In most other situations, it is best to avoid using Low wattage charger. Although, for a one-off use they are fine, continuous usage will harm your battery in the long run.
