These days, portable power stations have exploded in popularity, and for good reason; they're one of the most convenient ways to have a reliable backup supply of power on hand for just about anything - from camping and other outdoor activities to emergencies or living completely off-grid. Before deciding on which portable power station to buy, battery life is one of the most important featuresidal factors. This will be a follow-up post about hand-in-hand with what impacts the battery life of portable power stations as well as how to pre-estimate the runtime of these batteries.

What Impacts the Battery Life?

Battery Capacity: A power station's ability to carry as much power is what determines how long its battery can last and is measured in watt-hours (Wh). Bigger batteries have more capacity for energy storage, and so this is why they can be longer lasting. Most total capacity available for a single run is between 100Wh and up and over 2000Wh with larger capacities offering the best overall operating time.

How much power certain devices can draw when they are connected to the power station directly impacts how long their battery will last. The battery will reduce faster if the supplying device draws high power. You can power an estimated runtime of the device using the wattage which is powered by then dividing that value by the capacity of the power station.

Power Consumed by Device: Taking into account how much power the device is known to consume For instance, LED lights do not consume electricity as much as filament light bulbs so obviously you will have a longer battery life when using the power station with LED lights compared to the same power station and incandescent bulbs.

Idle Power Draw: Some power stations will use a small amount of power simply by being on but not actively supplying devices, and this can happen 24/7! It also depends a lot on the model and affects how long the power station can stay charged without using Fyfe

Battery: Generally the performance of the battery depends on temperature so ultimately if the temperature is low then probable battery will probably last longer. High-performance temperatures, i.e. \/ hot or cold, can have adverse effects on battery capacity and runtime.

Battery health: Capacity may diminish over time, reducing battery the age of a battery as it will lose capacity with use. Taking good care of your battery can help extend its life.

Estimating Runtime

Here is the formula you can use to calculate how much longer one charge on a portable power station will last.

Runtime =(Battery Capacity *Device Power Draw) Runtime (hours)=Battery Capacity (Wh)Device Power Draw (W)

If a generator can handle 500Wh and you have a device that uses 50W, then this is the kind of proposal based on runtime:

Runtime=50050=10 hours.

Real-World Examples:

Camping: A 300Wh power station for a 60W fan gives nearly about 5 hours of use

Emergency Power: About 5 hours(power 200W refrigerator-1000Wh)

Off-Grid Living - A 2000Wh power station with the assistance 300W TV can work for approximately 6-7 hours.

Summary

How Long Will a Portable Power Station Battery Last on One Charge? Understanding these factors and running those calculations via the formula provided will give you a rough estimate of the amount of time you can expect to run your devices with any given Portable Power Station, whether it be used for outdoor adventures, emergency preparedness, or off-grid living.
