Using a twin adapter like this one provides convenience to drivers and their passengers who have multiple accessories to charge simultaneously.
Although slightly larger than many other products at just under half a pound, this universal car charger features a self-recover safety function that allows the charger to recognize when its power transmission limit has been reached and it will overheat. This recognition of full charge, known as intelligent circuitry, is paired with the Short Circuit Protection. Together, these two features set the T-Mobile Compact Dual USB Charger Adapter apart from many of its competitors.
