Here's why:
* Amperage is the current: A higher amperage (2A) means more power is flowing to the device. A lower amperage charger (0.5A) won't provide enough power to charge the TomTom GPS efficiently.
* Potential damage: Using a lower-amperage charger can potentially damage the GPS device. It may cause the battery to charge very slowly, or even worse, could overheat and potentially cause damage.
Recommendation:
* Use the recommended charger: The best approach is to use the charger that came with your TomTom GPS or a charger that specifically meets its power requirements (5V 2A).
* Check the device manual: Your TomTom GPS user manual will likely state the recommended charging specifications.
In short, it's safer and more efficient to use a charger that meets the power needs of your device.
