Beaver Electronics Co. has debuted a unique fast-charging external battery for the iPhone, which it’s dubbed “Quarter,” because it takes less than a quarter of the time to charge compared to a normal external battery. The secret lies in the charging method — Quarter has a built-in MagSafe port that allows it to be connected to MacBook’s MagSafe Power Adapter.
Apple does not allow third-party companies to use its MagSafe technology, so Quarter has been created without Apple’s permission and with components Apple likely would not approve of, but its super fast charging capabilities are undeniably enticing.
Design wise, Quarter is similar in size to an iPhone 6 Plus. It’s just as wide and a bit shorter, but quite thick and heavy. It’s 12.5mm thick and it weighs 180 grams. It’s made from aluminum and has an an extra lip at the top with a hole that could be attached to a bag or backpack, but given its size, I’m not sure anyone would want to use it that way so that extra bit of material is extraneous and an unusual design choice.
