iPad Battery and Keyboard Pack
An ingenious all-in-one unit that connects to your iPad. Gives up to 90 hours on a full charge! The built-in keyboard is similar to a standard Apple keyboard, with island-style keys.
This is for 2nd, 3rd and 4th generation iPads - that is, everything up to the iPad Air and not the 1st generation iPad. Of course it doesn't fit the iPad mini either. It's a 4,000 mAh lithium polymer battery.
This might seem a little pricey, but for 90 hours on a full charge, you're talking some serious battery life! This is for the on-the-go professional or student who needs a couple of days between charges. Great for vacations and trips to different countries where you never know when your next charge will be or if you have the converters for the outlet.
The keyboard is nice too, and it makes it so that your iPad can be your primary computer. Typing on the iPad screen with your fingers is ok, but not great for prolonged use - typing with your fingers hitting real keys is much more tactile and intuitive and you can feel when you make a mistake. (At least we've seen that we can type much faster with a real, physical, keyboard.)
So yeah, it's $130 bucks, but if you want a keyboard and need a nice, beefy battery, then this might be the unit for you!
