External Laptop Batteries – The PowerPad 130

Web Worker Daily has nice things to say about Electrovaya’s PowerPad 130, an external add-on laptop battery that promises upwards of 10 hours of additional run-time on a single charge. Reviewing the device, Samuel Dean says he got an additional 6.5 hours of battery life on his Thinkpad X40.

The PowerPad certainly has a lot of interesting features, including a small LCD display that depicts how much juice it has left and a couple of USB ports so cell phones, MP3 players and other USB-rechargeable device can be recharged directly from it.

On the other hand, this will set you back $299 and adds and additional 2 pounds to whatever other gear you’re toting.
