The Anker 511 Charger (Nano 3) is a compact 30W USB-C GaN wall charger for people who want one portable charger for a compatible phone, tablet, earbuds, or MacBook Air; its cable is sold separately.
Recommended For
- Phone users who want a compact everyday or travel charger for one USB-C device at a time; its small U.S. foldable-plug design and 30W output suit bag or pocket carry.
- iPhone and compatible USB-C phone owners who want a small wall charger for faster single-device charging, rather than a multi-device charging station.
- Tablet users who need a compact charger for top-ups at a desk, hotel, or between outings; the reviewer found 30W adequate for an iPad Air and other lower-powered devices.
- MacBook Air owners who need a small backup or travel charger for lighter use and are comfortable with slower charging than a higher-wattage adapter.
Real-World Use Scenarios
- For a day out or short trip, pack the charger with a compatible USB-C cable to top up a phone from a wall outlet; its compact size and foldable plug make it easier to carry than a larger laptop brick.
- When a MacBook Air needs power away from its usual charger, use the Nano 3 as a compact backup or to keep the laptop running during lighter work; it can charge an Air, but it is not a fast-charging replacement for a higher-wattage adapter.
- At a desk or bedside, use it to charge an iPad Air between uses; Anker cites about 50% charge in 45 minutes for the fifth-generation iPad Air, with actual time varying by device and use.
- For a compatible Samsung phone, use it as a small single-device wall charger when you want fast wired charging; the phone and cable must support the required charging standard for the expected speed.
- At night or between outings, charge earbuds or another small USB-C accessory; it can serve as the same compact charger, though these devices may not charge faster than they would with a lower-wattage adapter.
