Anker took a single-port 45W GaN charger, squeezed it down to roughly the size of Apple’s old 20W cube, and put a little screen on top.
That screen shows wattage, temperature and charging mode. On recent iPhones and iPad Pro, it also names the device and reads out its battery level. Underneath, it’s a commodity product with a premium twist, so the only real question is whether you’ll ever look at the screen often enough to justify paying for it.

One-sentence verdict: A tiny, quick single-port charger that iPhone 15–17 owners will enjoy; the smart features stop at Apple, and Galaxy phones that need 5A PPS won’t reach their top speed.

Tiny. Anker lists it at 34 × 35.5 × 40 mm and 75 g, close to Apple’s old 20W cube.
The prongs fold flat, and they also lock at 90°. Sounds like a gimmick. Then you plug it in behind a bed, or squeeze it onto a power strip next to a fat adapter that would normally block the neighbouring socket, and it stops sounding like one. Colours are black, white, blue and orange.
The screen is small but bright enough to read at a glance. It sleeps after a while and wakes when you tap the touch area on the side, but the display itself isn’t a touchscreen, so don’t go poking at the numbers expecting them to do anything when you want to change modes.
There’s nothing to install or pair: plug it in, add your own USB-C cable, and it starts charging straight away.
The controls take a minute to learn. One tap shows charging status, a double-tap switches between Auto and Care modes, and a two-second press flips the display 180°. It won’t turn 90°, though, so in a sideways outlet you’ll be reading the numbers sideways.
Peak output is 45W (20V⎓2.25A), and an iPhone won’t pull anywhere near that. Cult of Mac measured about 31W into an iPhone and 43W into a 13-inch iPad Pro. Anker rates the iPhone 17 Pro at 50% in about 20 minutes, and AppleInsider’s test came in just under. So who’s the headroom for? iPad Pro and small laptops, mostly, and a MacBook Air will charge from it too, just not quickly.
Care Mode lowers the charging temperature for long overnight sessions, and Anker claims the phone runs up to 9°F cooler than on a standard 45W charger. That’s the company’s own figure. Still, it’s a sensible idea for a brick that lives by the bed.
Samsung owners get the short end here, because the listed 3A PPS covers 25W Super Fast Charging but not the 45W mode, which needs 5A.
Works with:
Not compatible:
Anker gives it an 18-month warranty. It launched in January 2026, so it’s had nine months in owners’ hands, and the Amazon rating has stayed at 4.7 across more than 5,000 ratings without any sign of a heat or failure pattern. The power-bank recalls on Anker’s recall page don’t include chargers.
At $25.99, it costs about what Anker charges for a two-pack of its plain 45W bricks, and it charges no faster. You’re paying for the size, the clever prongs and the screen. Will you actually glance at the readout, or use Care Mode overnight? Then it’s a fair premium. No? Buy the plain brick.

| Product | Best for | Key advantage | Main drawback | Price |
|---|---|---|---|---|
| Anker Nano 45W Smart Display Charger (this review) | iPhone 15–17 and iPad Pro owners who want one small brick for the bag and the bedside | Very small for 45W: about 34 × 35.5 × 40 mm and 75 g, per Anker | One USB-C port, and no cable in the box | $25.99 |
| Anker 45W USB-C Charger Block, 2-Pack | Two rooms, same speed | Two 45W bricks for about the same money | No screen, bigger, fixed prongs | $29.99 |
| Belkin 45W Compact USB-C Charger | Lowest cost 45W | Cheaper and compact | No display or smart modes | $19.99 |
| Samsung 45W Super Fast Charging Charger | Galaxy owners | Supports Samsung 45W Super Fast Charging 2.0 | Larger, no display | $24.90 |
| Anker Nano 65W GaN II PPS Charger | Laptop headroom | 65W for MacBook Air and Pro | Bigger, no display | $29.99 |
iPhone owner who likes the screen? This is the one. If you just want fast charging, Anker’s 45W two-pack gets you two bricks for about the same money. Galaxy owners should buy the Samsung 45W, because it’s the only one here that unlocks 45W Super Fast Charging, and for a laptop, step up to the Anker Nano 65W.
For an iPhone owner, it’s a lovely little charger. Small enough to forget about, quick enough that your iPhone’s own charging limit becomes the bottleneck, and the folding prongs fix an annoyance you’ve probably had for years. The screen is a nice extra, not a necessity, though recognition and Care Mode make it more than decoration on the phones it supports.
Scope is the reservation. The smart features are built for iPhone 15–17 and specific iPad Pro models, and the 3A PPS limit keeps Galaxy phones out of their fastest mode. Outside Apple’s world, or if you’d never look at the screen, a cheaper plain brick does the same job.

Figures marked “(Anker)” are the manufacturer’s published claims. “N/A” means the value is not listed on the Amazon listing or the Anker product page.
Yes. Any USB-C iPhone fast-charges over USB Power Delivery. As of October 2, 2026, Anker’s recognition list stops at the iPhone 17 series, so the device name and battery readout may not appear for an iPhone 18.
No. You get the charger and a welcome guide, so bring your own USB-C cable.
At 25W, yes. The listed 3A PPS output can’t drive Samsung’s 45W Super Fast Charging 2.0, which needs 5A.
No. You tap a touch area on the side to wake it, double-tap to change modes, and hold for two seconds to flip it 180°.
