A lot of basic solar-powered calculators don't have batteries at all. Covering the solar panel will shut it off.

- AshamedCaptain 6y agoYeah, what I mean (and has been better put elsewhere) is that the consumption of your average calculator is so low as to be practically negligible (<1mW?), otherwise capable of running for years on a depleted battery. Which is why they may work from such a small solar panel, but at the same time it says nothing about the solar panel itself.
