Every day, for health reasons, I drink decaffeinated coffee with coconut oil, butter, & whole creme. Naturally, to get these oils to blend with the coffee, they need to be whipped at high speed (to emulsify the oils). Over the past few months I have bought 6 so-called coffee whips. These are devices shaped like a stick blender, but they have a circular coil of wire at the end of a thin shaft. It rotates quickly & whips the coffee. I’m sure you’ve all seen them.
Well, they have all died, a couple of them in less than a month. It was frustrating. I even contemplated designing my own that would last longer. I found what looks like a decent motor on Amazon, & I figured I would use two 18500 Li-on batteries in series to get 7 to 7.5 volts. It was going to be a pretty involved project. Then,
I don’t drink coffee, but I drink cacao and these devices are perfect to solve the cacao powder in milk without getting any chunks.
However for my task this works fine. I have a version from “Severin”, which works here for years. I put normal two AA rechargeable batteries in, which last about 5 month or so until they need a recharge.
I looked at that unit, but decided on the Dremel because it’s a known quantity: i.e. it’s a well-known company with a reputation for making high quality products. One factor I did not mention: I drink around ten cups of decaf coffee a day. I think that’s why the others died so quickly – I use them much more than most people use theirs.
