How Much Does It Cost to Run a Phone Charger in India? (2026)
Charging a smartphone from empty takes 10 to 20 watt-hours, so a full year of daily charges is about 5 kWh. Chargers left plugged in draw well under a watt with nothing attached.
A typical phone charger (10 W) costs ₹0.060 per hour, or about ₹3.60 per month at 2 hours a day in India. Cheap to run
| Wattage | Per hour | Per day | Per month | Per year |
|---|---|---|---|---|
| Low (5 W) | ₹0.030 | ₹0.060 | ₹1.80 | ₹21.90 |
| Typical (10 W) | ₹0.060 | ₹0.12 | ₹3.60 | ₹43.80 |
| High (25 W) | ₹0.15 | ₹0.30 | ₹9.00 | ₹109.50 |
Formula: watts ÷ 1000 × hours × price per kWh. Typical use is 2 h/day ≈ 7 kWh per year.
In India, with electricity at ₹6.00 per kWh (source: Typical urban domestic slab rate; national average ≈ ₹5.5/unit FY2025-26, 2026-04), a typical phone charger costs ₹0.060 per hour and about ₹43.80 per year at 2 hours a day. Each ₹1.00 of electricity buys roughly 16.7 hours of use.
How to lower the cost of running a phone charger
- There is nothing to save here. Charge as you like.
- Unplug chargers only if you want a tidy outlet, not for the bill.
- Fast chargers do not use more energy per charge, they just finish sooner.
In standby it draws about 0.1 W, which adds roughly 1 kWh (₹5.26) per year if it is never unplugged.
