Ive seen a lot and used a bunch of different chargers over
the years but what I have now is the Sirius Charger from
Peak Electronics.

This has been the best purchase I have ever made.
Its utterly reliable and completely idiot proof.
No buttons or dials or different modes to worry about.
Just plug it in.

I have not used any other charger since I purchased it.
I dont even know where the wall wart for my radio is.

Its built into a rugged steel box and made in the USA.
