We live in a time where phones are demanding more from the outlets we plug into, and the Anker 523 Nano charger, priced at $19.99 (down from $29.99), is like a silent revolution. This little white brick, slightly bigger than the original 20-watt Apple adapter, packs 47 watts into a 3 oz package. Foldable prongs snap flat against the back so it can fit in a pocket or the side of a backpack. This accessory is perfect for anyone upgrading (or has upgraded) to the iPhone 17 which Apple just released with the promise of charging to 50% in 20 minutes with a 40-watt adapter.
When you take one out of the box, the first thing you notice is how unassuming it feels in your hand—smooth plastic, no rough edges, just a pair of USB-C ports that look ready for whatever you throw at them. When you plug your new iPhone 17 into each port, it negotiates up to 45 watts when used alone, reaching 50% in the time it takes to browse through a few notifications. Apple engineered the iPhone 17 battery to manage this greater flow, which is complemented with improved software in iOS 26 that optimizes power needs based on usage. What exactly happens? Your phone consumes what it requires without overheating, and the Anker maintains the current by monitoring temperatures over 3 million times every day via its built-in safety mechanism.
- Charge 2 Devices at Once: With 27W from one USB-C port, and 20W from the other, you can fast charge your iPhone and your iPad at the same time.
- High-Speed Charging: Utilize either USB-C port to provide up to 47W of power to charge a MacBook Air or other USB-C notebooks at impressive speeds...

Plug in a Galaxy S25 or a Pixel 10 alongside your iPhone and the ports will split the load—one at 27 watts and the other at 20 watts—for simultaneous top-ups that rarely fall short of what each device needs. Samsung’s fast charging gets its due, reaches speeds that match the phone’s own 45-watt capability when used alone, while Google’s adaptive charging also plays nice, prioritizing battery health over brute force.
A MacBook Air M2, M3 or M4 draws 45 watts from one port, that’s plenty to get through an email and video chat morning without overheating. The Dell XPS 13 and HP Spectre x360 do the same, enough to get through light editing or browsing marathons. Even when you daisy chain and charge a phone via the laptop’s pass through, the Anker stays stable and doesn’t throttle under the combined load.
Anker’s ActiveShield 2.0 keeps an eye on voltage and heat 24/7, shutting down if anything goes wrong – twice as vigilant as their older models. Users report no melted ports or unexpected shutdowns after months of daily use in outlets from airport lounges to bedside tables.
