About Watts & Whys
Portable power, explained. No hype, no sponsored rankings, just the right answer for your situation.
We live out in the country. The last couple of winters, bad storms knocked our power out for one to three days at a time.
That's how we got interested in backup power. We wanted to find something that would keep the things we needed running at our house, without having to buy a whole-home generator. Watts & Whys is where we share what we learn along the way.
Watts & Whys helps people choose the right portable power station, solar generator or home backup battery for what they actually need to run.
Most "best power station" lists rank the same handful of models for everyone. But the right pick for keeping a fridge cold during a three-day ice storm is not the right pick for running a Starlink Mini at a campsite. So we start from your situation: what you need to power, for how long, and on what budget.
What we do
- Do the runtime math. Every guide is sized from real power needs. Our Runtime Calculator lets you do the same math for your own devices.
- Compare real specs. Capacity, continuous and surge output, battery chemistry, recharge speed, weight and warranty, side by side.
- Read what owners say. We dig through owner reviews for the problems spec sheets never mention, and we tell you who each pick is not for.
What we don't do
- We don't accept payment for placement or rankings.
- We don't claim to have tested products we haven't. When a guide is based on research rather than hands-on use, we say so.
