An apparatus may include a plurality of power inputs configured to receive direct current from a plurality of external power adapters that convert alternating current to direct current. The plurality of external power adapters may include a primary external power adapter and at least one backup external power adapter. The apparatus may also include a power output configured to provide direct current to a device. In addition, the apparatus may include a switching mechanism that, when the primary external power adapter is operational, supplies direct current from the primary external power adapter to the power output and, when the primary external power adapter fails, supplies direct current from the backup external power adapter to the power output. Various additional apparatuses, systems, and methods are also disclosed. |
