Griffin on Monday added to the stack of CES product announcements by introducing the Travel Power Bank for Apple Watch. As you can see in the photo, the accessory is essentially a tiny battery pack with an inductive charging pad for Apple's wearable.
Griffin says that the built-in battery is of the 800 mAh variety, which is good enough to fully recharge the Apple Watch up to four times before needing more power for itself. That's not too shabby for a device that is so small it can be attached to a keychain.
