Anker Nano Magnetic Power Bank 5,000mAh (Qi2)
A thin magnetic battery you can keep using while it charges
A 0.33-inch-thin 5,000mAh Qi2-certified magnetic power bank with 15W wireless charging and up to 20W over USB-C. It measures 4.02 x 2.77 x 0.33 inches and comes with a cable.
Our take
A cabled power bank ties your phone to a battery while it charges. On a walking tour or in a cramped airplane seat, that cable is in the way. A magnetic one fixes that.
This one snaps onto the back of the phone, so you keep using it while it charges. It's only 0.33 inches thick, Qi2 certified for 15W wireless charging, and it also charges over USB-C at up to 20W when you're in a hurry. The trade-off is efficiency. Wireless charging loses some energy as heat, so 5,000mAh gives you less than one full recharge. It adds noticeable weight to the back of the phone, and phones without built-in magnets need a magnetic case to hold it.
If you have a MagSafe iPhone, this is the magnetic bank we'd buy. Check the price before you book.
Who it’s for
iPhone users with MagSafe or a magnetic case who want a cable-free top-up on travel days.
Skip it if
Skip it if your phone doesn't support magnetic charging or you need more than one top-up. A standard cabled power bank holds more for the money.
Anker Nano Magnetic Power Bank 5,000mAh (Qi2): questions people ask
Are magnetic power banks allowed on planes?
Yes. Like every power bank, it goes in your carry-on, not your checked bag.
What does Qi2 certified mean?
Qi2 is a wireless charging standard with magnets that line the charger up with the phone. Certified chargers like this one support up to 15W on compatible phones.
Why does wireless charging give fewer charges?
Some energy turns into heat when power goes over wireless. Use a cable if you want the most out of the battery.
