The ORB Xbox One Dual Controller Charge Dock is a low cost way of avoiding the annoyance of changing batteries in Xbox One controllers.
Included are two replacement battery packs, a USB lead and the dock itself.
The Orb dock has a light around the base which is usually green until you pop a controller in that needs a charge, at which point it turns red.
Being a fairly bright light it’s a pity the Orb dock doesn’t have a way to turn the lights off without removing the power as they can be distracting if you want to charge your controllers while watching TV.
Keep that in mind when deciding where to place this, rather than powering via the Xbox you could always pop it out of sight and use a spare USB plug adapter.
A great low cost way to stop having to use batteries, with the added bonus of having somewhere to store your controllers when not in use.
