Anker’s “Nano Power Bank (5000mAh, MagGo, Slim)” is a slim, compact mobile battery (8.6mm thick) that supports magnetic wireless charging—so you can charge your smartphone just by placing it on top. With Qi2 certification and MagSafe compatibility, it pairs particularly well with iPhones (MagSafe-compatible models), making it easy to quickly handle battery anxiety while you’re out and about.
A built-in magnet on the back keeps the iPhone securely aligned. Since it supports Qi2-certified wireless charging (up to 15W), you can reduce the hassle of plugging/unplugging cables and power up quickly even on the go or in the car. The fact that it’s positioned for iPhone 15/16/17 series and Air models is a plus for people who already know exactly which device they’ll use.
If you’re looking for a “thin but actually useful” power bank that won’t take up much space in your bag, this is a strong match. With a 5000mAh capacity, it’s less about long-distance travel power and more about “staying ready during outings” and “supplemental power for short to medium periods.” It’s especially suited for anyone who wants something lightweight and easy to carry.
Currently on Amazon for ¥5,490 (21% off; regular price ¥6,999). Wireless charging power banks tend to be priced higher, so if you’re looking to “try wireless charging conveniently,” this price makes it much easier to consider.
