Universal Battery from APC charges laptops and USB devices

If you’ve ever gone to purchase a universal battery for your laptop, you know that it can be a pain making sure that you get the voltage correct. Sure, you could just guess, but if you get it wrong, your entire laptop could go kaput. This new external battery from APC takes all of the guesswork out of it.

These new batteries come in 70-watt and 90-watt versions and will automatically detect the correct voltage before sending any juice to your laptop. As a bonus, it features two USB ports for charging things like phones and iPods. If you pick up the 90-watt model, you can expect to get around 8 hours of extra life out of your notebook, which makes it well worth the $225 price tag. The smaller version will run you $135.
