I was wondering who was going to catch that.
My electric razor is a rechargeable. It’s good for a few days.
However, one of the advantages of the modern world is the miniature DC to AC inverter. I have one that was designed for laptops. It only puts out about 45 watts, but that works for my shaver.
I even used it once on a jobsite. My little pen solderer just wasn’t getting hot enough. I checked the voltage, about 105 volts. Brownout conditions.
I used the inverter and completed the connection.
You can even set it up with a compact fluorescent lamp. No electricity, what’s that?
Those are great. My first one was a 75 watt cigarette-lighter unit, it eventually died and was replaced with a 150 watt model. I've used it for internet connection (laptop and cellphone) during extended periods of power outage, to charge batteries for my new camera on the way to the recent camp-out, and various other things.
