NdFeB Magnet Charger
NdFeB magnet to make the world’s smallest charger
Nowadays, since portable batteries and mobile routers can be seen everywhere, we believe everyone may have the same feeling: they are too big and too heavy, and it always feels like you have a brick in the bag. Due to Scientific and technological progress, life becomes more convenient. So charging must catch up, that is to become smaller and lighter. Design mania shows you the smallest charger in the world that is being raised.
The Nipper emergency charger is very small. It is a small box of 17 x 17mm, plus a braided belt. It is the smallest mobile phone charger in the world. Best of all, it uses 2 dry batteries to recharge mobile phones. The design seems unbelievable, but it’s very easy to use. Just open the Nipper, install 2 section 5 battery and plug in the phone charging interface to charge the phone. When it is not used, hang it on the key chain or put it in the bag to solve the unexpected need.
The Nipper emergency charger contains 3 neodymium magnets, which play a role in conducting connections as well as fixing batteries. The circuit board in Nipper is a Boost converter, which can convert the dry battery voltage to 5 V to charge the mobile phone. The experimental results show that 30 minutes can help charge 10% power and 60+ minutes is required for 20%.
