\text{9.87 h}

5 steps

Identify the given values.
The energy required to charge the phone is $14.8 \text{ Wh}$ .
From the previous problem, the power output of the charging device (S20 3) is $1.5 \text{ W}$ .
Use the formula relating energy, power, and time.
The formula for energy is:
$E = P \times t$
where $E$ is energy, $P$ is power, and $t$ is time.
Rearrange the formula to solve for time.
To find the time, we can rearrange the formula:
$t = \frac{E}{P}$
Substitute the given values and calculate the time.
$t = \frac{14.8 \text{ Wh}}{1.5 \text{ W}}$ $t \approx 9.8666 \text{ h}$
Round the answer to a reasonable number of decimal places.
$t \approx 9.87 \text{ h}$
The final answer is $\text{9.87 h}$ .
