Outdoor Power Supply Life Cycle

How long does a portable power station last?

A portable power station’s lifespan is largely determined by its battery cycle life. This means the amount of times it can be charged and recharged before capacity drops.

What is the life expectancy of a power supply?

No general answer can be given. Well, the power supplies' heating is usually much higher at 90% than at 80% and extremely high at 100%. So considering heating, it's usually good not to put more than 80% load on the supply for longer periods. Life expectancy is not really equal to MTBF!

How long does a battery last in a power station?

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%.

How long does a TDK rws50 power supply last?

TDK RWS50 power supply lists the MTBF at 4,170,949 hours !!!, which is about 500 years. Yet they contain mechanical fans that usually have at most 40,000 hrs, and best electrolytic caps are rated at 100,000 hours at 60C. Although the life expectancy doubles with every 10c drop in operating temperature, I still can't figure out the 4M hrs rating.

How do you store a power station?

If you’re not using it, store your power station in a cool, dry place with a 50% charge. (Remember, don’t store it anywhere where it will overheat or freeze.)

What can you use a power station for?

This should be obvious, but you must ensure your devices match the power station’s output to avoid overloading. That means you can use it to charge things like phones, laptops, portable lights, cameras, etc. - but you should try to power heavy-wattage items like washing machines, vacuuming cleaners, etc.
