What is the capacity of a portable power station?
One of the most important things to consider with power stations is their capacity. This refers to the amount of power It can store and provide to you, and it’s an essential factor to keep in mind when you’re looking for a portable power station that will meet your needs.
In this article, I’ll be discussing what capacity means in the context of a portable power station, and how it can affect the performance and functionality of the unit. I’ll also be providing some examples of different portable power stations and their capacities, so you can get a better sense of what to expect when you’re shopping around.

What is Capacity?
When it comes to portable power stations, capacity is measured in watt-hours (Wh). This is the amount of energy that It can store and provide to you, and it’s an important factor to consider when you’re looking for a portable power station that will meet your needs.
For example, if you have a portable power station with a capacity of 100 watt-hours, it means that it can provide you with 100 watts of power for one hour, 50 watts of power for two hours, and so on. The more watt-hours a portable power station has, the more power it can provide to you, and the longer it will last before needing to be recharged.
How Does Capacity Affect Performance?
The capacity of a portable power station can have a significant impact on its performance and functionality. For example, a portable power station with a high capacity will be able to provide you with more power for longer periods of time, which can be particularly useful if you’re planning to use it for camping or other outdoor activities.
On the other hand, a portable power station with a low capacity may not be able to provide you with as much power, or for as long, which can be limiting if you’re planning to use it for more demanding applications.
Examples of Portable Power Stations and Their Capacities
Here are a few examples of portable power stations and their capacities to help you get a better sense of what to expect when you’re shopping around:
- The Anker PowerHouse 400 has a capacity of 400 watts-hours, which means that it can provide you with 400 watts of power for one hour, 200 watts of power for two hours, and so on. This makes it a great option for camping or other outdoor activities, as it can provide you with plenty of power for your devices.
- The RAVPower RP-PB056 has a capacity of 56,000mAh, which is the equivalent of 201.6 watt-hours. This portable power station is great for charging your phone, tablet, or other small devices on the go.
- The Goal Zero Yeti 400 Lithium has a capacity of 396 watt-hours. It is designed for light to medium power needs like powering a small refrigerator, lights and charging devices.
Portable Power Station | Capacity (Watt-hours) |
---|---|
Anker PowerHouse 400 | 400 |
RAVPower RP-PB056 | 201.6 |
Goal Zero Yeti 400 Lithium | 396 |
The reason why the capacity of the Goal Zero Yeti 400 Lithium is not 400 watt-hours is that there is always some energy loss during the charging and discharging process. This is known as the Coulombic efficiency of the battery. The Coulombic efficiency of a battery can be affected by a variety of factors such as the type of battery, the age of the battery, and the temperature of the environment.
Additionally, some manufacturers may choose to use a slightly lower capacity battery in order to increase the overall lifespan of the unit or to make the unit more affordable.
In the case of the Goal Zero Yeti 400 Lithium, it uses a Lithium-ion battery which has a high energy density and long cycle life, allowing it to have a capacity of 396 watt-hours. The capacity rating of 396 watt-hours is still considered high and suitable for light to medium power needs.
In conclusion, the capacity of a portable power station is an essential factor to consider when you’re looking for a unit that will meet your needs. The more watt-hours a portable power station has, the more power it can provide to you and the longer it will last before needing to be recharged. Remember to keep in mind your power needs and usage before choosing the right portable power station for you.
