Adapters commonly list outputs from about 18W up to 40W. Typical listed wattages include 18W, 20W, 30W and 40W. Actual charging speed can vary depending on the adapter model, cable, and the device’s charging negotiation.
Most adapters use USB‑C ports; many also include USB‑A ports or ship with USB‑A to USB‑C or USB‑C to USB‑C cables. Expect USB‑C to be the primary connector for newer adapters.
Product descriptions commonly list protections such as overcurrent, overvoltage and short‑circuit protection, along with smart chips that manage input power and prevent overcharging or abnormal current flow.
Many chargers have two ports to charge multiple devices at once. Common combinations are dual USB‑C ports or one USB‑C plus one USB‑A. Some car chargers and combos add dual Quick‑Charge USB ports or built‑in retractable cables alongside USB‑A/C ports.
Several product details state roughly 25–30 minutes to reach about 50% battery on recent iPhone models; actual times vary by model, charger, and cable.
