Where Should I Pack My Power Bank When Flying?

I pack my own power bank in my carry-on every time, and I would not put it in a checked bag unless I wanted to risk a problem at security or at the gate. If you are flying with a phone charger, a laptop battery pack, or a small backup battery for travel, what matters […]

Can You Charge Your Phone on a Plane?

I’d keep this simple: yes, you can usually charge your phone on a plane, but I would never count on the seat USB port as my only plan, and I definitely would not buy a big portable power station thinking it will solve air-travel charging. If you are trying to decide what to carry for

Can I charge my electric vehicle for free?

I get this question a lot as an electrician and a solar owner: yes, you can sometimes charge an electric vehicle for free, but usually only in specific situations. In the real world, ?free? EV charging usually means workplace charging, promotional public charging, or using solar power that you?ve already paid to install on your

My job is usually resetting expectations before somebody spends

Can charging an electric car with a solar panel save money?

I tell homeowners this all the time: yes, you can save money charging an electric car with solar, but only when the system is sized around your driving and not around a fantasy version of your house. I have seen people save real money with a simple rooftop setup, and I have also seen people

Does a solar lease make financial sense?

I’ve looked at a lot of solar proposals, and my blunt take is that a solar lease only makes financial sense when you need a lower monthly payment right now and you are willing to give up most of the long-term savings. If your main goal is getting the cheapest power over 20 to 25

How do I use a solar calculator by zip code?

I use a solar calculator by zip code as a rough screening tool, not a buying decision, and I would not trust one by itself to tell you whether solar is a smart move for your house. If you are trying to figure out whether solar will actually help your bill, budget, or backup goals,
