Mp2637 charge timer

I have a question about the formula for calculating the mp2637 charging time.

When calculated according to the given formula, it is not calculated as 2.4 hours. Did I calculate it wrong?

thank you.

Hello! Welcome to the MPS Technical Forum!

I calculated the total charge time using the above formula, and I am getting about 2.4 hours as well.
The answer is in seconds, so please divide the answer you get by 3600, to get the answer in hours.
