How to Convert Battery Watt-Hours (Wh) to Milliamp-Hours (mAh) — iFORWAY Makes It Easy

In today’s tech-driven world, understanding battery capacity is more important than ever. Whether you’re selecting a smartphone, portable power station, or energy storage device, knowing how to interpret different units can help you make smarter decisions. Today, iFORWAY will guide you through the process of converting watt-hours (Wh) to milliamp-hours (mAh) and explain why this knowledge matters.

What Are Watt-Hours (Wh)?

Watt-hours (Wh) are a common measure of energy that represents how much power a battery can provide over a period of time. Simply put, 1 watt-hour means the battery can supply 1 watt of power for one hour.

For example, if your iFORWAY device uses a 20 Wh battery, it can deliver 20 watts of power over the course of one hour. This unit is particularly useful when describing the energy storage capacity of larger devices like portable power stations and backup batteries.

What Are Milliamp-Hours (mAh)?

Milliamp-hours (mAh) measure battery capacity and are typically used for smaller devices like smartphones, headphones, and compact tools. mAh tells you how long a battery can supply a specific current. For instance, a 1,000 mAh battery can provide 1 ampere of current for one hour, or 1 milliampere for 1,000 hours.

This unit is especially helpful when evaluating the battery life of portable electronics.

Why Convert Watt-Hours to Milliamp-Hours?

When purchasing new devices or replacing a battery, you might need to convert watt-hours (Wh) to milliamp-hours (mAh) to compare battery capacities across different products. For instance, iFORWAY’s portable power solutions often use Wh for energy storage, while smartphones and other smaller devices use mAh.

By understanding these conversions, you can better compare battery performance and select the best option for your needs.

How to Convert Watt-Hours (Wh) to Milliamp-Hours (mAh)

To convert watt-hours (Wh) to milliamp-hours (mAh), you need the battery’s voltage (V). Use the following formula:

Where:

• Wh is the battery’s energy in watt-hours.
• V is the battery’s voltage.
• mAh is the resulting milliamp-hour capacity.

Example:

If you have a 5 Wh battery with a voltage of 5 volts:

This means a 5 Wh battery running at 5 volts has a capacity of 1,000 mAh.

How to Convert Kilowatt-Hours (kWh) to Milliamp-Hours (mAh)

For larger battery capacities, such as those used in iFORWAY home energy storage systems, you’ll often see kilowatt-hours (kWh). To convert kWh to mAh, use this formula:

Example:

If you have a 0.005 kWh battery with a voltage of 5 volts:

This means a 0.005 kWh battery running at 5 volts has a capacity of 1,000 mAh.
