How long does a portable power station last?
A portable power station's lifespan depends on the type of battery inside. Most new portable power stations, including all the models we recommend here, feature LiFePO4 battery technology, which lasts far longer than older lithium-ion technology. How much more? LiFePo4 power stations will last for more than 3,000 charge cycles, or about 10 years.
How much power does a portable power station use?
Imagine your total power consumption for these devices amounts to 150 watts, and your portable power station has a 500Wh capacity. Using the runtime calculation formula, you might estimate approximately 3.3 hours of power. However, this doesn't account for an 85% conversion rate. In reality, your runtime would be reduced to around 2.8 hours.
