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 world’s smallest phone charger will be there for you.

How Do I Use It?

It couldn’t be easier. When not in use, The world’s smallest phone charger is always with you: attached to your key ring or in your pocket or bag. When you need to charge your phone, simply open The world’s smallest phone charger, place two AA batteries between the magnets and connect it to your phone.

Compatibility

The world’s smallest phone charger currently works with any phone or other device with a micro-USB connector (Samsung, HTC, LG, Nokia, etc). We’re also developing a version compatible with the iPhone, so stay tuned. However, if you have an adapter (not included), it can also work with iPhone devices.

Charging Time

For a modern smartphone, The world’s smallest phone charger will give an extra 10% battery capacity in 30 minutes, and 20% in just over an hour.

How Does It Work?

The world’s smallest phone charger contains 3 neodymium magnets. They have the double function of holding the batteries together while at the same time making an electrical connection to The world’s smallest phone charger circuit board.
