A blackout may affect everything from business meetings and internet access to lighting and basic home appliances. That’s why a portable power station as an alternative energy source becomes a necessity nowadays for those who need quiet, green and portable power during emergencies.
However, there is a crucial point to consider before purchasing a portable power station:
What appliances will your portable power station be able to operate?
Can it supply power to a fridge? Can it handle fans, Wi-Fi routers, computers, TVs, kitchen equipment?
This all depends on the capacity and the output power of the station itself, measured in watt-hours (Wh) and watts (W).
What Is a Portable Power Station?
The portable power station is basically a rechargeable battery device with multiple outputs like AC outlets, USB ports, and DC outputs.
These devices can typically be charged via:
- Wall outlet electrical power supply
- Solar panel charging
- Car charging
- Charging from a USB-C port on compatible devices
After charging the device, you can attach any compatible device to the power station.
Unlike the traditional stationary inverter, the portable power station is portable and independent and can therefore be used both at home and outdoors.
Understanding Watts and Watt-Hours
However, before deciding on what appliances you will be able to operate, you need to know about the following three concepts.
Watts (W)
This concept refers to the level of power consumption that is required for operating the appliance.
For instance, if your portable power station has a continuous power output of 500W, then usually the level of the total connected load should not exceed the supported level.
Watt Hours (Wh)
Watt hours refer to the level of battery power supply and allow you to estimate how long the appliances will work.
Higher Wh level means higher backup power time of your appliances.
Surge Watts
Some motor or compressor-powered appliances might need extra power at the start-up time.
As it was mentioned above, the source states that the starting surge of 400-450W could be needed when starting a 150W refrigerator.
Which Home Appliances Can a Portable Power Station Run?
Here are approximate figures from the supplied guide:
