I’ve reviewed my share of portable power stations, and when I receive a new one to test, I like to sit down and figure out the target market.
Some power stations are big and heavy, while others are smaller and easier to move around. Some have more battery capacity, some are expandable with extra batteries, and some have inverters with greater capacities to power your largest appliances.
Some power stations are designed to be used as an uninterruptible power source (UPS). If you keep the power station plugged into the wall, any device you plug into the power station’s outlets will keep working if the electricity goes out. If you sleep with a CPAP at night, keeping it plugged into a UPS means you won’t even notice if your home’s power goes out — the CPAP will keep working.
