Because each outlet in the power strip is not supplying more than the max power that the outlet it’s plugged into can provide. If anything plugged into a power strip were to draw the max electricity the breaker would trip to protect the wiring and other things plugged into it. Power strips are about the ease of on demand electricity for multiple appliances, not power amplification.
