Target offers the BlueLounge Kii Charge and Sync Lightning to USB Key in Black for $13.98. Choose in-store pickup to avoid the $4 shipping fee. That's the lowest price we could find by $26. It fits on your keychain, allows you to charge and sync Apple devices without a cable, and features a self-locking cap and flexible body to prevent breaking.
A4C offers the Apple 12-watt Power Adapter and Lightning Cable, model no. A1357, for $12 with free shipping. That's tied with our mention from a week ago, the best now by $9, and the lowest total price we've seen. The wall charger features a USB connector.
