The Nipper currently works with any phone or other device with a micro-USB connector. It will be developed a version compatible with the iPhone. For a smartphone, it will give an extra 10% battery capacity in 30 minutes, and 20% in just over an hour.

It contains 3 neodynium magnets that holds the batteries together while at the same time making an electrical connection to the circuit board. This circuit is called a boost converter, it turns the power from the batteries into a 5v power supply.

The project campaign is fully funded on the Kickstarter and reached its funding goal of $6.000, the early bird pricing are gone, but you can still get it for $15, an estimated delivery is on April of 2016.
