It is generally safe to use a micro USB cable with a 5V charger to charge a PS Vita without harming the battery. The PS Vita requires a 5V power source for charging, so using a micro USB cable with a 5V charger should work just fine. However, it is always recommended to use the charger and cable that are specifically designed for the PS Vita to ensure the best charging performance and to avoid any potential damage to the device.
