How to make MagSafe2 charger stronger
I used to have a L shaped MagSafe charger for my 2010 MBA. Now I have my 2015 MBP I now need to use the T shaped MagSafe2 charger. The only issue is because the angle the wire is on the connecter (and not going in the port as much) this makes it very easy for it to fall out of my computer when I move it (it gets very annoying!).
Is it possible somehow to make the charger stronger without modifying it too much?
There is a product that also can help with this.

It works by using a tiny machined piece of metal inside of the port on the computer to strengthen the connection of the magsafe 2 connector.
You can turn it into an approximation of an L or even a U by the simple expedient of tying a knot in it.
This is my standard way of dealing with any awkward cable.
It's not perfect, but boy, it's cheap ;-)
L-knot
U-knot
From comments - the U-knot is achieved by simply wrapping one end through a second time, if it's not clear from the picture.
BTW - keep the knot very loose, so you don't damage anything.
From further comments -
Of course, no knot is going to help if the cable gets yanked, in any direction; this idea is really just to set the cable off in the direction of the PSU, if that's not to the left of the machine.
Just reducing its tendency to want to be straighter in the 'wrong' direction, nothing more, & reducing pull angularly, rearwards, which is what the older L-plug would do naturally, thereby reducing the lever length of the T-cable in that one direction.
There are three axes to consider when measuring the force needed to separate a MagSafe 2.
There are two great articles that cover the basics:

The MagSafe 2 is quite strong if you have a direct yank or pull as discussed in the USB-C discussion above. The snuglet or a knot you tie won't help much at all for the direct yank. However, I've not heard of people feeling that one direction was too easy to disconnect.
The MagSafe is very underpowered if you push or pull it in the N (normal force) direction in the above diagram from Mac World. This is also the “put the Mac on a pillow” force that many people don’t want to have disconnect the charger. The snugglet fixes this problem exceptionally. It physically shims the magsafe adapter into the unibody frame for a snug fit. A cable knot won’t help you there either since the force needed to disconnect is so little, the knot can’t absorb or redirect a pull in this direction (and if you are pushing on the magnet end, no cable knot can help.
The last axis you can consider is if you pull the cord along the table plane (assuming your Mac is open on a kitchen table) and pull the cord towards the chair where you would sit. The force needed to disconnect the adapter is less than the force needed for a yank/pull but more than is needed in the vertical (normal force) direction. The snuglet helps here a little since a little is all that’s needed. A knot can help here both by acting as a shock absorber and to help possibly redirect some of that pull to the yank direction.
