This Disney Philips candlelight is similar to another set I have by Philips, the difference being the Mickey picture on the light.
The size of a small cup, it charges by plugging into a USB port (with the supplied USB lead). There was no power / plug in charger with this product.
When charged, tilting the candlelight to the side turns it on. It emits a flickering glow, and is safer than a combination of children, pets and naked flames, making it a safe night light for children or Disney obsessed adults such as myself!
