How to Select the Appropriate Portable Power Station Battery Capacity

What exactly is battery capacity, and why is it significant?

Assume you're camping in the middle of nowhere. Your laptop and phone abruptly lose power, and you discover that your portable power station battery is also dead. That can't be fun, can it?


This is why determining the appropriate portable power station battery capacity is critical. The total amount of energy that a power station can store is defined as battery capacity. You won't be able to charge all of your devices if you don't have enough. As a result, understanding how to select the appropriate battery capacity for your portable power station is critical to avoiding the disappointment of having a dead phone, laptop, or other camping gear in the middle of nowhere.


How is the capacity of a battery determined?

You may have noticed that power stations refer to battery capacity in terms such as "500 Wh" or "20000 mAh." If you're wondering what this means, let me explain. The capacity of a battery is expressed in either watt-hours (Wh) or milliampere-hours (mAh). These figures indicate how much energy a battery can store.


Watt-hours (Wh) are units of measurement for the amount of energy consumed in one hour at a rate of one watt. If your portable power station has a battery capacity of 500Wh, it can power a device that uses 1 watt for 500 hours or a device that uses 50 watts for 10 hours for 500 hours.


Milliampere-hours (mAh) are units of energy that store enough energy to allow one ampere of current to flow for one hour. So, if your portable generator has a battery capacity of 20000mAh, it can store enough energy to power a device that uses 1 amp for 20000 hours or a device that uses 2000mA for 10 hours for 20000 hours.


Simply put, the greater either of these numbers, the more power that portable power station can store and the longer it can charge your devices.


How to Calculate the Required Portable Power Station Battery Capacity

Step 1: Determine how much power you require to power your devices.

This step is straightforward: make a list of your devices and their wattage requirements. If you can't find this information on the device or the packaging, look it up online.


Add everything up after you've made your device wattage list. This total is the starting point for your required battery capacity.


Step 2: Determine how long each charge cycle will require you to use the power station.

When deciding on battery capacity, consider how long you'll use the power station each time. For example, do you intend to use the power station briefly to charge your laptop or phone, or will you use it for hours at a time to power your campsite?


Thus, it is not only about the amount of power required, but also about how long the power must be sustained. If you require power for more than 2-3 hours, choose a portable generator with a larger battery capacity than the total wattage of your device. For example, if you have 500 Wh of devices, buy a 1000 Wh power station. This ensures that it will last as long as you require.


Step 3: Examine the typical battery capacities of common household appliances and devices.


Remote control: 0.1-0.2Wh

Wireless earbuds: 0.2-0.3Wh

Bluetooth headphones: 0.4-1Wh

Smartwatch: 1-2Wh

Digital camera: 4-8Wh

Portable speaker: 6-12Wh

Smartphone: 8-12Wh

Tablet: 20-40Wh

Portable refrigerator: 100-150 Wh

50-inch flat screen TV: 150Wh

Laptop: 150-300Wh


Recommended power stations by battery capacity level:

OtterBox Fast Charge ($55) – up to 74 Wh

Goal Zero Yeti 200X ($299) – up to 187 Wh

EcoFlow RIVER Pro ($549) – up to 720 Wh

EcoFlow DELTA ($1,099) – up to 1,250 Wh

Goal Zero Yeti 3000X ($3,499) – up to 3,032 Wh


Your portable generator's battery capacity decision will determine whether your devices always remain fully charged. It's like filling up your gas tank before a long drive; you want to make sure you have enough juice so your car doesn't run out of gas before you get there. Calculate the wattage of your device before you purchase a portable power station to ensure that you choose the right battery size for your requirements.
