Bring that extra battery boost to your smartphone and never go flat, using just a pair of AA batteries.
(August 12, 2015) The Nipper is a seriously small portable phone charger. It is small enough for you to carry it around wherever you go, doesn’t depend on you remembering to charge it, and it relies on something readily available everywhere: household AA batteries.
The Nipper was primarily designed for emergency use. When all else fails, when all hope is lost - in situations where you desperately need to use your phone but have no access to laptops, electrical sockets, wind turbines or solar panels the Nipper will be there for you.
