Does it matter which charger I use?

It doesn't matter which charger you use for your amateur radios. It is essential that the charger is compatible with the battery type and voltage of your radio to ensure safe and efficient charging. Using an incompatible charger can not only shorten the life of the battery, but also increase the risk of damage to the device or even hazards such as overheating or fire damage. When purchasing a charger, be sure to choose the radio manufacturer's recommended model or a compatible third-party charger that is specifically specified for your device type.
