Important features in electric screwdrivers for furniture dis/assembly
You need tactile feedback to avoid stripping the threads.
In my experience, Ikea style knock-together furniture has a fairly narrow &quot;acceptable torque&quot; range. This is easily detected by hand feel.  However, any power driver will give  you dead nerves.  You will not be able to feel the correct torque, and the machine will be a &quot;bull in the china shop&quot; and blast right through the correct torque before you even know what's happening.
Is it OK for disassembly?  Sure if you remember to switch it to &quot;loosen&quot;.  Is it OK for &quot;rundown&quot;? Sure, but the final few twists should be by hand.
The best power driver I ever had was cheapie. But it was shaped like a screwdriver, with the result that you could effortlessly switch between power and hand operation at any moment.
However I have found a much more satisfactory method: a &quot;Speed wrench&quot; with a bit holder.

Now this gives me the speed and power of a power driver but the control and tactile feedback of hand driving.
They cost a little bit of money but y'know what? 5 years hence they won't be in the junk bin waiting to go to the electronics recycler.
