Went through a brief online lesson on power chords, it seems all you do is fret the root node which is the actual note you want, plus 2 other notes on the same fret with a space between from the root node, under the subsequent strings next to the root.

The lesson uses a 3 finger approach but I couldn't do this properly especially when moving closer towards the pickups, so I have 2 choices, fret only 2 strings (1 root and the other) or fret the other 2 notes with 1 finger, the ring finger which is what I did, and found it much easier without involving the 3rd finger (pinky).

Is this all there is to it to power chords ? Just fret a root node and the 2 other notes (with ring finger).

Fingers are not 'strong' enough yet, need to get used to moving them apart this far and pressing/holding down harder for the ring finger to fret 2 strings.

Ring finger fretting two strings? As far as i remember, the two strings are fretted with the ring finger and pinkie. At least that's what i was thought to do..

That was what the lesson thought but I find it much harder to get a clear note, especially when you move downwards near the pickups where the fret spaces are ridiculously small.

I have big hands also. I rather build a strong callous to fret 2 strings with 1 ring finger though, and it's faster/easier to coordinate and move fast imo to catch the right chord.

Just practice. It wouldnt be a problem later on. Taking easy way outs to avoid working on your weaknesses wouldnt help you get better.

Not to say its wrong, but you need to work your fingers anyway. Work on what you're weak at.

half agree half disagree. It depends on who taught you this lesson. I can teach you that the earth goes round the moon. But of course you wouldn't listen, because i know craps about the solar system.

Although i agree that you should work on your weaknesses, but what if you can do it another way or even a better way? For example, i can't play with my teeth and i can play much faster with a pick or fingerstyle. Should i work on playing with my teeth? After all that is my "weakness". There are many ways to fret a G-chord, which one do you use and why? The way i fret a G-chord depends on which chord i was playing previously and which chord i will play next.

So the best in my opinion is to practice all the ways you can play it (applies to any type of instrument). Both at what you are weak at and what you are strong at. Because the minute u stop practicing what you are strong at, it will soon turn into a weakness. I know it sounds abit cheesy but it's true. I thought it was crap at first too, but quickly realized the limits of fretting/playing only one way.
