Aaoyun 20000mAh Power Bank with 22.5W USB-C PD and Built-in Cable

The Aaoyun 20000mAh is a mid-range portable charger with 22.5W USB-C Power Delivery, built-in USB-C cable, and dual ports (USB-C input/output + USB-A). It delivers roughly 12000–14000mAh of real-world usable capacity—typical efficiency loss for the 20000mAh rated spec. The 22.5W PD output is moderate: adequate for phones and small tablets, but slower than 30W+ rivals for laptop charging. Built-in cable is convenient and reduces what you need to pack; the external USB-A port supports simultaneous charging of a second device. Recharge time is moderate (6–8 hours from empty with a standard 18W charger). Weight and bulk are average for 20000mAh—not pocketable like 10000mAh banks, but lighter than high-capacity laptop banks. Pass-through charging is not confirmed. Brand presence is minimal outside Amazon; Aaoyun has no established reputation in power-bank communities (r/PowerBank, r/UsbCHardware) or major tech review coverage. Return and defect data are sparse, limiting confidence in long-term reliability. Positioned as a budget-friendly option for light travelers and daily phone top-ups; not suitable for heavy laptop use. Competes with entry-level INIU and budget-tier Anker models on price, but lacks their review volume and community validation.
