Pros & cons
Pros
- Two USB-C cables are built into the pack, so there is nothing extra to carry or lose
- 45W output tops up laptops and tablets, not only phones
- 20,000 mAh holds enough for a multi-day trip or several devices in sequence
Cons
- More reserve than a single phone top-up needs on a short day
- Bulkier to pocket than a 10,000 mAh charger
Skip it if
Skip it if you only top up a phone on short days — a 10,000 mAh bank like the INIU 45W is easier to pocket.
How we assessed it
We synthesized this
Two USB-C cables are built into the Anker pack itself, so the thing you always forget is already attached. That matters on the road: 45W of output tops up laptops and tablets, not only phones, and the 20,000 mAh reserve carries a multi-day trip or several devices charged one after another. It is the pick for travellers who want a single pack to cover a whole kit.
Be honest about the size, though. All that reserve makes it bulkier to pocket than a 10,000 mAh charger, and it is more than a single phone top-up needs on a short day out — a smaller bank suits that. Our read is a synthesis of Anker's documented capacity, output and built-in cables rather than a hands-on charge test — see how we test.
