Electric Razor Charge Lifespan Calculator

Electric Razor Charge Lifespan Calculator


Imagine a world where your trusty electric razor could tell you its life story, from its first buzz to its last. Sounds like a dream, right? Well, buckle up, because we’re about to dive into the electrifying world of calculating your razor’s charge lifespan! It’s not rocket science, but it might just save you from showing up to that important meeting looking like a castaway.

Electric Razor Charge Lifespan Calculation Formula

The formula to calculate the charge lifespan of an electric razor is as straightforward as a clean shave. Here it is, dressed in code:

def calculate_charge_lifespan(battery_capacity_mAh, power_consumption_mA, charge_efficiency=0.85):
Calculate the charge lifespan of an electric razor.
– battery_capacity_mAh: The battery capacity in milliampere-hours.
– power_consumption_mA: The razor’s power consumption in milliamperes.
– charge_efficiency: The efficiency of charging, default to 85%.

– lifespan_hours: The lifespan of the razor on a single charge, in hours.

usable_battery_capacity = battery_capacity_mAh * charge_efficiency
lifespan_hours = usable_battery_capacity / power_consumption_mA
return lifespan_hours

Electric Razor Charge Lifespan Categories

Category Lifespan Range (hours) Interpretation
A > 10 Exceptional; ready for life’s hairy moments.
B 7 – 10 Reliable; your beard won’t see it coming.
C 4 – 6 Moderate; for the less fuzzy among us.
D 1 – 3 Low; living on the edge of a power outlet.
E < 1 Emergency; it’s time for a new razor, buddy.
