Which outdoor power supply has the longest life

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.

To help you decide, I tested the efficiency, in a variety of scenarios, of the best portable power stations from Jackery, Oupes, EcoFlow, Anker, Goal Zero, Grecell, Bluetti, Dakota Lithium, Lion Energy, Vtoman, and Oupes. ↓ Jump to the Rest of the Field ↓ What to Know Before Purchasing a Portable Power Station

LiFePo4 power stations will last for more than 3,000 charge cycles, or about 10 years. That's far longer than the 500 or so charge cycles and 3 to 5 years you'll get from an older power station with a lithium-ion battery. How long does it take to recharge a portable power station with solar panels?

Portable power stations are more powerful and cost effective than ever before. And, thanks to advances in lithium-ion battery technology, they're also lighter and more compact. Whether you've been dreaming of van life or are building out your emergency kit in advance of that next blackout, there is a power station that will meet your needs.

This means the amount of times it can be charged and recharged before capacity drops. Most modern power stations, including Pisen's models, use lithium batteries, which typically last hold 500 to 1,000 charge cycles (battery cycle life) before their capacity drops to around 80%.

While a particular power station might claim to hold 1,000 watt hours, the actual amount of usable power you can get out of it is a different story. The best portable power stations also have an onboard computer that shows you how much energy is left in your unit, as well as how much power it's currently using.
