Puts Standard Batteries to Shame

You already have the best laptop, now get the external battery that delivers all the power you need. For work AND play. Quickertek's Battery for theMacBook Pro extends your MBP time instantaneously- allowing you to charge the battery and use your macBook Pro simultaneously. Ready to use right out of the box, it contains a powersupply and all cables.
If you *have* to work, why not work outside or at the coffee shop or by the pool. With the right external battery, you have the freedom to decide where and when to work. Do what you want, when you want with the right power solution. You could even take one of the super-long airline flights. Get your work done and still have time for fun - ebay, games and online shopping - whatever you want.
Don't cripple yourself with the distraction of a dying battery. Work until you decide you're done. With up to 12 hours of extra power, it will outlast you. It even recharges faster than you too - only four hours for a full recharge.
