This is why it’s good to have some kitchen/dish gloves. And if you can get them with extra long sleeves, the better. It’s actually worse if the nasty water gets inside them 🤢
I used to get “reusable gloves” but they wear out too easily so then I bought some industrial use silicone dipped gloves for handling lye but instead I use them exclusively for dishes and cleaning now. I have a second pair for handling lye and other caustic chemicals.
All these creative solutions for doing this without sticking your hand in makes me wonder how people usually do the dishes that doesn’t involve putting your hands in anyways? Like gloves would help with both, but the rest?
By “regular” batteries I assume you mean alkaline ones like your standard AA and AAA. Lithium Ion batteries aren’t really more “powerful”, more likely the circuit was simply designed for constant 5V because that is cheap and easy nowadays. Small lithium batteries like the one used here and a simple charging circuit and port are dirt cheap when purchased in bulk.
Not to mention there’s a size difference both for the battery itself and mounting area for it. For something like a AA battery there needs to be a user accessible battery compartment to replace them. It’s cheaper and easier to just not do that.
A normal AA battery is probably more powerful than this tiny thing. That cell is probably 3.7v 250 mah at best. My “shitty” ikea rechargeable AAs are like 900 mah, and the good ones are 2400 at 1.2V. 3.7 * 250 is 925 watt hours, 1.2* 900 is 1000, and 1.2 * 2400 is 2800.
The biggest benefit is these are easily and quickly rechargeable.
An alkaline AA may have more capacity, but the LiPo has lower internal resistance and it’s electrolyte is flammable. The worst the alkaline would do it shorted or punctured is get warm and poop out KOH.
I updated the post to reflect the “(cat)” toy nature in the alt text first line. Sorry I took this for granted as a clearly understood context as a common cat toy (in the USA) and failed to describe it as such.
I posted it here because I wanted to reach the most significant audience. Posting this in electrical engineering would have missed the majority of people this is intended to inform.
