Induction-based charging is always a crowd-pleasing trick (at least among this crowd of one). It feels vaguely magical to lay a device down on top of a mat and watch the little battery light turn on. CTA Digital's new Non Contact Induction Charging Pad will enable DSi and DSi XL owners to enjoy the convenience of setting a thing on top of another thing. By replacing your battery with the special battery included with the kit, you'll be able to charge the device through contact with the charging stand with four lights (not five) to indicate charge level.
The device is available now from Amazon and other retailers. We're personally going to hold off for a while, as we often do with third-party charging products, and make sure there aren't any fire-related issues.
