Frequently Asked Questions

What is the best backup source for a power outage?

A portable power station and solar generator are ideal backup power sources. Since these devices operate independently of the power grid, they stay clear from any impact of a widespread outage. In other words, when the grid is down, your lights, Wi-Fi, and other essential electronics can still be up and running, thanks to these independent power sources. One prime example is our DELTA Series, which juices up most appliances you need in a blackout.
