Power Outages in the UK and US

Power cuts are becoming more frequent on both sides of the Atlantic. In the US, the average household experiences over 8 hours of power outages annually, with states like Texas, California, and Florida seeing significantly more due to extreme weather events.

Whether you're preparing for hurricane season, winter storms, or heat wave-related grid failures, having reliable backup power is no longer a luxury, it's becoming a necessity.

Outage Impact

The 2021 Texas winter storm left over 4 million homes without power, some for nearly a week. Recent California heat waves have triggered rolling blackouts affecting millions.
