GoKey adds four handy gizmos

GoKey is a slim, compact keychain accessory that provides four handy items in one
As you might expect, the GoKey has the look of an oversize key.
Its big round head terminates in a USB stem, which is where you plug it into your PC to access the 8GB, 16GB, or 32GB of onboard (and password-protected) storage.
USB connection also charges the GoKey’s internal battery, which the developers say can charge your phone for “up to two hours.”
At the other end, a stowaway cable (Lightning or Micro-USB) folds out to connect to your smartphone for syncing and/or charging (check).
Finally, the GoKey pairs with your smartphone via Bluetooth to help you when either goes missing.
If you need help finding your keys, an app points the way.
When it’s your phone that can’t be found, a press of the GoKey makes the phone ring.
The effective range? Up to 100 feet, according to GoKey’s makers.
