I replaced my MacBook charger with this compact wall unit - and wish I'd done it sooner
The Cuktech 15 is an ultraportable wall charger with four ports and a 140W output, letting you charge your laptop and other devices at once.
Adrian Kingsley-Hughes/ZDNETI can't believe how small wall chargers are getting thanks to gallium nitride (GaN) technology. This is a result of using GaN transistors which are a lot more efficient than older silicon semiconductors, alongside intelligent design that helps to dissipate the heat generated. I recommend this product for its combination of features relative to value -- as of right now you can get one for $50, a nice discount on the usual price of $70.
