Using a mixer is not "a must".
You should be able to whisk 1-2 egg yolks together quite easily which a whisk and some elbow grease.
How do you think we beat egg yolks for the centuries prior to electricity?

I don't even bother with a whisk for something that small.
(the only wisk I have is medium sized balloon whisk, I don't have any small ones).
I find a fork and a small bowl work well for up to about 3-4 eggs.
I tip the bowl towards hand with the fork so I can get a better angle on it, and it keeps the eggs from spreading out too much across the bowl.

I think a great option for beating small amounts, if you don't just use a whisk, is a hand-cranked egg beater.
They're cheap and easy to use.
I have one I got from my Mom many years ago, and it works great.
If you get one, don't let batter or egg or whatever dry on it--wash (or at least rinse) as soon as you're done using it.
They're hard to get dried-on stuff off of because the spaces are small.

I'd use my immersion blender , which gets plugged in.

have you tried tilting your blender?
i had the same problem for awhile and tilting the blender so the blades could reach the eggs
did the trick.
just be sure to have a firm, two hand hold; one on the base of the blender and one on the glass.
then just tilt the top towards you.

This is what I use currently - a drill on a high speed using the micro mixer attachement.
I think Dremel Stylus on low would work as well, but I don't have that one.
When I make waffles for 4 people, I use 4 yolks and my immersion blender gets the traction needed, but for two yolks I need a narrow glass and this.

One option I've found works well is, I had picked up a immersion little milk frother gadget, and it works like a tiny immersion blender.
Honestly, I find beating eggs can be done just fine by hand, with a fork and a bowl or with a whisk (sometimes just "churning" between the hands if the whisk is too large or the quantity or bowl too small), but the little frother works when I've lumps to be worked out of something, or actual blending would be nice but the quantity is small - and since I've got it, I can use it for things like beating eggs if I'm in a hurry or feeling lazy.

Many sauces and pastries call for beaten yolks. You need to beat yolks well, till they are thick again and are lemon-colored, so using mixer is a must. But if you need only one or two egg yolks, regular mixers are too big for the task. What I'm currently using is a battery-driven micro mixer, and it is not powerful enough and eats up batteries fast.Can anybody suggest a good solution to the problem?

A hand whisk or fork can work best here, or you can use an immersion blender, milk frother or hand drill with a micro mixer attachment. While 2 eggs should be Ok to beat by hand, you can also try using an immersion blender.
You can easily whisk 2 egg yolks by hand. Try using a hand powered egg beater. Try using an immersion blender.
