Notion Ink teases 15-hour battery life for Adam slate

My interest in Notion Ink's Adam tablet continues to grow. Although I wouldn't call this one an iPad killer just yet, there's a lot to like about the device, including a transreflective Pixel Qi display that's viewable in direct sunlight and a Tegra 2 system-on-chip equipped to accelerate HD playback, Flash content, and games. In a post on the official Notion Ink blog, founder Rohan Shravan has now revealed some details on battery life.

According to Shravan, the Adam is running a minimum of 15 hours on a full charge. Nvidia's Tegra 2 may deserve much of the credit, as the SoC is said to consume less power than the slate's LCD, Wi-Fi, 3G, and speaker components. Shravan pegs the chip's typical power consumption at 60-70mW, and says it tops out at around 200mW under heavy usage.

Adding to the intrigue, Shravan claims that the Adam's internal speaker actually produces decent sound. The slate is also shown connected to a USB keyboard and mouseā€”no proprietary connectors here.

We don't yet have a firm release date on the Adam, but it's expected to arrive late this year or early next. The Android-based device is slated (ha!) to cost $498 fully equipped, $450 if you drop the Pixel Qi display or 3G, and $399 if you ditch both and stick with Wi-Fi and a standard LCD. Thanks to Engadget for the tip.
