The magnetic connector works as well as a standard USB connector. It's all I use.
The setup includes a small 'plug' that you insert into the telescope's USB port. The cable has a corresponding end that magnetically attaches to the plug. The main benefit is that if the cable snags, it simply pops off rather than potentially damaging the telescope.
There are different types of cords available. Some have a round connector and others an oval. The round connectors will not fit on the S50.
