The Standzout Helix is one of the best ways to charge an Apple Watch. You just plug it into the wall, and lay it on top. It has a compact housing that stores up to two meters of the Apple Watch charging cable, which allows for reducing cable clutter.
It is quite a decent product, and will recommend it for your Apple Watch needs. I can be purchased on the Standzout site for a now reduced price of $19.99, and available in colors of white, clear, black, and glow-in-the-dark.
