# Wh (Watt-hour)

A Watt-hour (Wh) measures the amount of electrical energy a device can consume or provide over an hour. It combines power (in watts) with time (in hours), giving a clear idea of the energy capacity of batteries or devices, such as those in portable power stations like the Anker SOLIX models.

#### Significance and Application

Watt-hours are crucial for determining how long a device or appliance can run on a specific energy source. For example:

- A **1000Wh battery** can theoretically power a 100W device for 10 hours.
- It helps compare the capacities of power systems, such as portable power stations for medical equipment or emergency use.

The **Anker SOLIX F1200** offers 1229Wh, while the **F2600** and **F3800** provide 2560Wh and 3840Wh, respectively​​​.

#### Example Scenario

If powering a 300L vaccine refrigerator requiring **2.6 kWh/24h**, an Anker SOLIX F1200 can sustain it for approximately 11 hours, while the F3800 can extend up to 35 hours​.

#### Strategic Integration or Technical Implementation

- **Calculating Runtime**: Use a runtime calculator to match the Watt-hour capacity with your device's power requirements for optimal results. Access the [Runtime Calculator](https://www.upsequip.com.au/runtime-calculator/) for accurate projections.
- **Backup Planning**: Systems like the [Anker SOLIX F1200](https://www.upsequip.com.au/emergency-ups-vaccine-protection/) or [F3800](https://www.upsequip.com.au/medical-refrigeration-power-security/) ensure uninterrupted medical refrigeration during outages.

#### Related Terms

- **Kilowatt-hour (kWh)**: Equivalent to 1000 Watt-hours, often used for billing electricity consumption.
- **Ampere-hour (Ah)**: Indicates battery capacity, focusing on current supply over time.
