HyperMac Stand props up iPad; extends battery life by 16 hours
The shining feature is really the 40-watt-hour rechargeable lithium-ion battery, which can extend the iPad’s battery life by a whopping 16 hours. (You charge the stand via mini-USB.) Users can monitor how far the battery has charged up by the 5-stage lighted LED indicator.
The HyperMac Stand is available now for $129.95. Pricey for an accessory, but at least it sounds useful.
