Wireless chargers are not completely universal, as there are differences in charging standards. Some wireless chargers use the Qi standard, while others use other standards such as PMA or A4WP. This means that if you have a wireless charger that supports the Qi standard, it can only charge devices that support that standard.

Therefore, before using a wireless charger, you should first make sure that it supports the standard adopted by the device you want to charge. For some wireless chargers with multiple standards, you can check the compatibility list in the product description to confirm that it supports your device.

It should be noted that even if both devices use the same standard of wireless charging, their charging speed and efficiency will vary due to different device characteristics. Therefore, when buying a wireless charger, in addition to considering its standards and compatibility, you should also pay attention to its power, charging efficiency and other factors to ensure that it can meet your charging needs.
