Description
Anker Zolo 20 W Compact USB-C GaN Charger (A2699)
Single-port wall adapter with one USB-C output at up to 20 W—aimed at phones, wireless earbud cases, and tablets that do not need a high-wattage brick. Second-generation GaN internals target cooler day-to-day operation than many standard 20 W units.
20 W output
The USB-C socket supplies up to 20 W, often about three times quicker than bundled 5 W adapters, for fast charging on supported smartphones and many slimmer tablets, plus convenient case top-ups.
GaN II and size
- Operating frequency doubled versus conventional GaN designs, with an upgraded circuit and stacking layout
- Body roughly 25% smaller than earlier Anker 20 W models while keeping the same power rating
- Described as running about 13 °C cooler than typical 20 W chargers to ease heat stress on internal parts
Housing
A 3D transparent exterior and stacking-technology shell preserve a premium feel in a compact black 2-pin format. Cooler thermals plus the reduced volume help the charger stay comfortable to hold after extended use.
Works with
- Android handsets that support USB Power Delivery or similar fast-charging protocols
- iPhones when paired with a compatible USB-C cable
- Most tablets; very large tablets may charge slower than with their original higher-wattage adapter
The see-through finish is a design layer over Anker’s usual protective housing approach and is not described as reducing structural protection.
