You can charge different iPhone and iPad models the same way, but it does not mean you should. There are subtle differences between how the iPhone 17 battery charges as opposed to the earlier models, and getting it right can extend the life of the device. You can’t be expected to know the secret formula, but Anker’s 45W Nano Charger with smart display does, and charges with optimal effectiveness specific to each device.
This ultra-compact, ultra-intelligent charger is a must-have for iPhone and iPad users, and right now at Amazon it’s only $28 — a fat 30% markdown from its already-reasonable $40 regular price. Predictably, it’s moving very quickly at this low price, so don’t sleep on this one.
Little Charger, Big Brain
Anker has been continuously improving its Nano charger line for a few years now, and this version adds a display and iPhone-specific intelligence to what was already a compact, capable charging block. The screen needs just a tap to see real-time charging status, double-tap to switch between modes, or hold for two seconds to rotate the orientation. It turns off automatically after a minute so it’s not lighting up your nightstand all night. It’s a small quality-of-life addition, but if you’ve ever plugged in a phone at night and had no idea whether it was actually charging, the feedback is genuinely useful.
This Nano charger doesn’t just identify your device, it uses Anker’s innovative TÜV-certified Care Mode to automatically adjust power delivery based on battery level and lowers the charging temperature by up to 9°F compared to a standard 45W charger. That’s meaningful for overnight charging in particular, where sustained heat is the thing most likely to degrade a battery over time. The charger identifies iPhone 15, 16, and 17 series devices automatically — excluding the iPhone 17e — and extends compatibility to several iPad Pro models from 2020 onward. At full tilt, it pushes 45W and can charge an iPhone 17 Pro to 50% in about 20 minutes per Anker’s internal testing.
Pocket-Sized Power
The exceptionally small and portable design of the Nano falls in line with Anker’s overall motif. It’s about 47% smaller and 36% lighter than the original 30W Anker charger, and the prongs fold both 90° and 180°, which makes it easier to slot into outlets tucked behind furniture or cramped airport charging stations without wrenching the plug sideways to make it fit.
The Anker 45W Nano Charger comes in four colors — black, white, orange, and blue — and ships with an 18-month warranty and no cable, which is worth factoring into the total cost if you don’t already have a USB-C cable you’re happy with. For Apple aficionados who care about what long-term heat does to their battery — $28 is an outstanding price for what Anker has built here.
