Overview
The AOHI Magcube 40W is a tiny GaN wall charger that packs 40W of power into a near-perfect cube shape with foldable prongs. It features one USB-C port supporting Power Delivery 3.0 at up to 40W and one USB-A port with Quick Charge 3.0 at 18W. Its ultra-compact size and foldable plug make it one of the most travel-friendly chargers available.
Design & Build
The Magcube lives up to its name with a 1.18-inch cube design that is barely larger than a standard Apple 5W charger. The foldable US prongs sit flush against the body when closed, making it incredibly pocketable. The black or white matte finish resists scratches, and a subtle LED indicator shows power status. The two ports are positioned on the same face, and a small branding logo adds a premium touch. Build quality is solid, with a reassuring weight that hints at GaN components inside. The hinge mechanism on the foldable plug feels durable.
Performance
The USB-C port delivers up to 40W, enough to fast-charge an iPhone 15 Pro Max to 50% in about 25 minutes or fully charge an iPad Air in under 2 hours. It can also charge the Nintendo Switch at full speed in handheld mode. The USB-A port provides 18W QC 3.0 for Android devices. When both ports are in use, the charger intelligently splits power, typically delivering 20W to each port. The GaN technology keeps the charger cool even during extended use. PPS support enables Samsung Super Fast Charging on compatible Galaxy devices.
