Yes, you can use that charger on your Galaxy Tab A8, but I suggest sticking to using official chargers as they are built safely for your device. If you're using another brand's charger to charge your tablet, always make sure that it's an authentic one. USB Type C is really convenient.

Ensure that the charger, adapter and cable are Samsung Authorized and compatible with your device.
Even if adapters or charging cables appear similar, their quality and charging speed may differ. To preserve your Samsung Galaxy Tab A8 lifespan, make sure to use Samsung Authorized chargers and charging cables that are compatible with your specific device, as they are designed to maximize battery life. If you use products that are not specifically for mobile devices (travel chargers or standard chargers) or products that are not Samsung Authorized, your device may be damaged or not charge properly.
