If you own a Surface Pro, I highly suggest you get the Power Cover. It is $199 and I am getting anywhere between 6.5horus and 8 hours on a full charge. So worth it. The keyboard is an improvement over the type cover 1 as it isn't as noisy. I am not a fan of the touch pad on the Power Cover and Type Cover 2. (no clicking)
When carrying the device in a bag you don't notice the added weight, as well as when it sits on a table.
How it works if you don't already know:
When using the device off of a charger.
The power cover drains first, than the device itself, even if the power cover doesn't have any power, the keyboard still works.
When you charge the device it will always charge the device first than the power cover. It takes about 2 hours to charge both of them.
