If there was ever a multi-gadget charger that can take care of all iOS devices in one go, it's the Kanex Sydnee.
Most chargers that deal with several devices at once can handle 3 at most -- not the Kanex Sydnee. This particular creation can take care of four at once. While it's only one more than what the regular chargers on the market can handle, it's still super rare to find one that can handle this many. The cord has four USB outlets that will pump out 2.1 amps of power to each device. Once it's done charging, it'll automatically shut off. The piece also boasts a cable management design that will makes sure that tangles will never occur.
The Kanex Sydnee is only compatible with iOS devices such as iPads, iPhones and iPods.
