The cable was 6 pounds and fitted perfectly both ends ie in my macbook air and the power pack.

Warning : Don’t use normal non electrical tape as power packs get warm and only electrical tape is valid. Tips:

Try to use a correctly cut piece of heat shrink tube to neaten the soldering joint. Use flux to get a better soldering joint. Most solders come with flux or buy separate it make sure the imputiues don’t cause a bad joint. Test the joint using your needle nose pliers. I also used pike disgorger that is a great tool as you can grip and fix the nose on the subject very handy in holding these wires.

Should you do this ?
