Adjusted Purchase Price: Start with the base price. If the charger type includes specific components like a high-wattage adapter or a particularly long cable, a small adjustment might be applied based on typical market prices. For this model, we factor in the base cost and add nominal amounts for specific features.
Total Cost Over Lifespan: Multiply the Adjusted Purchase Price by the number of years the charger is expected to last. This gives a rough idea of the total investment.
Cost Per Year: Divide the Total Cost Over Lifespan by the Estimated Lifespan in Years. This provides the key metric for comparison.

Formula Used:

Cost Per Year = (Base Purchase Price + Feature Add-ons) / Estimated Lifespan (Years)

Variable Explanations:

Variable	Meaning	Unit	Typical Range
Base Purchase Price	The initial cost of the charger.	USD ($)	$5 – $30
Feature Add-ons	Nominal cost added for specific features like higher wattage adapters, longer cables, or extra ports. Calculated internally based on charger type.	USD ($)	$0 – $10
Estimated Lifespan	The anticipated duration the charger will function reliably.	Years	1 – 5
Cost Per Year	The calculated average annual cost of owning and using the charger.	USD ($) / Year	$2 – $25
Charger Type	Classification of the charging equipment.	N/A	Standard, Wall Adapter, Power Bank, Original TI
Cable Length	Length of the charging cable.	Meters (m)	0 – 3
Wall Adapter Wattage	Power output capacity of a wall adapter.	Watts (W)	0 – 18
Power Bank Capacity	Energy storage capacity of a portable power bank.	milliampere-hours (mAh)	0 – 20000
Number of Ports	Simultaneous charging capability.	Count	1 – 4
