Firstly, locate the inflation port, usually located in a corner or edge of the product.
Use matching inflation tools such as air pumps or manual inflators.
Inflate according to the inflation pressure requirements specified in the product manual to avoid excessive inflation that may cause the product to rupture.
For example, when inflating an inflatable mattress, you can first use an air pump to quickly inflate it to a certain degree, and then use a manual inflator to fine tune it to the appropriate hardness.
