Smartphone battery life has come a long way in the past few years, but nothing beats the peace of mind that comes with a power bank. Having a power bank with you means that, even on the busiest of days, your phone won’t leave you high and dry.

The Anker Nano 30W is a great shout if you want a power bank that feels a bit more “premium” than the usual cheap bricks you see discounted for Black Friday. It’s still pocket-friendly – roughly the size of a chunky old feature phone – but the frosted front and hidden colour display give it a much sleeker look.
Tap the button and the screen fades to life, showing an exact percentage plus a handy time estimate until it’s full (when you’re charging it) or empty (when you’re using it). That alone is a big reason to grab it; you actually know how much power you’ve got left, instead of guessing from a row of vague LEDs.

You get a built-in USB-C cable that both recharges the Nano itself and charges your phone, tablet or earbuds, so you’re never stuck hunting for a lead at the bottom of your bag. On the side, there’s an extra USB-C and a USB-A port, so you can plug in more gadgets when you need to.
With up to 30W over USB-C, it’s a particularly good pick for iPhone owners (it hits Apple’s fast-charge sweet spot for most models) and for quickly topping up most other everyday USB-C devices on the go.
Under the skin, the 10,000mAh capacity gives you enough juice for a full phone recharge and then some, and the Nano charges back up quickly when you do get near a plug.
That combination of clear battery info, fast charging, built-in cable and genuinely pocketable design is exactly why this is a power bank worth buying, especially at its newly discounted price.
If you want something smarter than the bargain-bin options, that you can throw in a pocket or bag and trust to get you through a long day or weekend away, the Anker Nano is a very strong candidate.
Cuter and classier than the average power bank, the Nano hides a neat little screen behind a smokily metallic front. It’s not quite as impressive on the technical side, but it can still hold its own against mid-tier contenders.
