Smartphone Camera Sensor Size & Fast Charging Calculator
Battery Life Estimator
Estimates runtime based on battery size and workloads.
Please enter valid positive numbers. Total load must be greater than 0.
Power Bank Charge Multiplier
Calculates full charges a power bank provides (accounting for 18% conversion loss).
Please enter valid positive numbers. Device capacity must be greater than 0.
Manufacturer battery claims are famously exaggerated. Our power calculators use real-world wattage draw curves to give you accurate runtime estimates for your specific daily workflow and travel setup.
- Real-World Battery Life Estimator: Input your laptop’s battery capacity (Wh), set your screen brightness, and select your primary task (compiling, 4K video playback, gaming). The tool applies verified base-load wattages to give you an accurate, no-nonsense runtime estimate.
- Travel Power Bank Charge Multiplier: Stop calculating raw mAh. Enter your power bank’s Watt-hours (Wh) and your device’s battery size. This calculator factors in the standard 15–20% heat/conversion loss to tell you exactly how many full charges you will actually get on the road.
