Anker PowerCore Fusion

The Anker PowerCore Fusion combines a wall charger and a power bank in one unit — plugged into an outlet it works as a standard charger with a foldable AC plug, and unplugged it functions as a standalone 5,000 mAh power bank. It provides two USB-A outputs and a maximum output of 15 W, so it is not a fast-charging device by current standards, more of a versatile, dependable all-rounder. It supports pass-through charging, meaning you can charge the unit from the wall while it simultaneously charges a phone. The trade-off is weight: at 187.4 grams it is considerably heavier than a dedicated power bank of similar capacity, the cost of combining two devices into one being the added bulk of the AC prongs and adapter housing. That makes it a poor fit for backpacking where every gram counts, but a sensible choice for trips that mix flights, hotels, and hiking, since it saves carrying a separate charger.
