3-in-1 charge cable 2A or 0.65A?

Is the 2A charge cable with 3 charging sub-cables always be 2 amp in actual usage?

The fact is that 2A is only valid when there is only one smart device is charged.

When 2 device are charged,the current for each is not more than 1A.

When 3 sub-cables are used for 3 smart phones or tablet or game machine,the current for each is 0.65A.
