Anker Nano Power Bank 10K 45W Built-In Retractable USB-C Cable: review
The Anker Nano Power Bank 10K 45W Built-In Retractable USB-C Cable (don’t worry, I’ll shorten it from here on out), is exactly what it sounds like. It's a small-sized portable charger with a built-in cable for on-the-go charging, and boasts a 10,000mAh capacity and 45W maximum power output.
The real draw of the Anker 10K 45W is its convenience. Firstly, that integrated charging wire is a massive plus. Simply pull it out, and it auto locks to the length that suits you best. To unwind, all you’ve got to do is pull and release – easy as you like. In addition, this model is pretty compact, meaning it can easily slot into a pocket or small bag.
Is its charging performance as efficient as its build? Well, it would be hard to answer that question with a one-word answer. First of all, there are some restrictions worth noting. A 45W maximum power output means that it can’t charge more demanding devices, like laptops, at peak levels – something that a lot of the best power banks are capable of. Its 10,000mAh capacity isn’t the largest either, though it will be plenty to charge most phones and a pair of wireless earbuds a couple of times.
Anyway, I tried charging my Samsung Galaxy S24 FE – which has a 4,700mAh battery capacity – and fast charging was activated, enabling my device to go from 0-100% in around 80 minutes. That’s as fast as I’d expect, so no complaints there.
After a while, though, I wanted to recharge the portable charger, and performance could’ve been a bit better. After about 10 minutes, I realized it was only charging at 19W. This is because the model throttles charging input to keep temperature in check. Still, I got a full charge after approximately two hours, which is still fairly decent.
And let’s go back to that temperature control note. Sure, the charger can get a little warm, especially if you’re also making use of its additional USB-A and USB-C ports and edging towards maximum power use. But it never felt overly hot. You can also check the battery temperature and health of the model using its inbuilt display.
The display itself is behind a translucent exterior, and can also update you on the power output from the integrated cable and additional ports – pretty handy. It's not the brightest display I’ve ever used, but it’s certainly a nice-to-have.
Something I really like about this model is its well-designed cord, which you can adjust to fit onto a backpack or a belt loop, for instance. The exterior itself also has an attractive metallic, glossy finish, as well as a textured surface, which enhances grip. It can be yours in a range of colors too, specifically: Aurora White; Phantom Black, which is the variant I tested; or Sprout Green.
For the power and build quality on offer, I’d also say that this model is priced pretty well. It has a list price of $59.99 / £49.99 / AU$99.95. We’ve tested cheaper rivals – like the Samsung 25W 10,000mAh Wireless Battery Pack – but that model has a considerably lower wattage.
Combine that with the integrated table and the fact that this model is regularly on sale already, and I’d say the Anker 10K 45W is a strong value pick worth checking out. If you need to charge a laptop or power hungry phone like the the OnePlus 13, for example, something mightier will suit you better. Otherwise, I’m generally a fan of what Anker has to offer here.

Should I buy the Anker Nano Power Bank 10K 45W Built-In Retractable USB-C Cable?
Buy it if...
You only need to charge your phone
For a lot of modern iPhones and Samsung phones, for instance, this is a powerful enough pick. 45W means you’ll be able to access fast charging, with the 10,000mAh capable of supplying multiple full charges.
You don’t already own a USB-C cable
One of the best things about this power bank is that you don’t need to buy a separate USB-C cable to make use of it. Simply connect your device to the integrated cable, and you’re good to go. Also, Anker says that the cable can survive more than 20,000 bends and retractions, so it should last for quite some time.
Don't buy it if...
You want to charge your laptop
Unfortunately, this model doesn’t have the firepower to charge more demanding devices like laptops or certain phones at maximum capacity. That’s due to its fairly modest 45W power output. I’d recommend a model with around 100W if you want to charge one of the best MacBooks, for example.
You’re looking for a super-cheap option
I’d argue that this model is pretty solid value for money, but there are certainly cheaper options out there if you’re looking to spend a little less. Having said that, you can often find the Anker Nano 10K 45W for less than its $59.99 / £49.99 / AU$99.95 list price, so keep your eyes peeled for a sale.

Anker 20,000mAh 87W Power Bank
Yep, I’ve got another Anker model for you, and this one’s really special. I used this one personally for a couple of weeks, mainly to extend the battery life of my Nintendo Switch 2. However, its 87W power output also means it can charge a lot of the most power-hungry phones at maximum capacity, and even juice up a good portion of laptops. With an integrated cable, additional USB slots, and a handy display, this power bank really has it all. Read our full Anker 20,000mAh 87W Power Bank review.
