What's worse than running out of power on your tablet, or any other device? Nothing, that's what. Suddenly, your cool new piece of technology has become an expensive paperweight. Fortunately, there are ways to boost your battery life so you can keep working as long as you need to.
Some tablets, like those made by Toshiba, have batteries that can be replaced by the user. One way to go is to buy an aftermarket battery pack that you can keep fully charged, and then swap it out for the old battery when yours runs out of juice.
Other tablets have attachments or docking stations that attach to the USB port or some other access point and provide an extra battery boost. There are a lot of options here; it's all about what you're willing to carry around with you.
