Every power bank is sold on mAh, which tells you how much energy it holds — not how fast it will charge your phone. A 10,000 mAh bank with 18 W will fill a modern phone in about an hour. The same capacity at 5 W takes all afternoon.
These are the power banks we stock, cheapest first.

What actually matters
1. Watts, not just mAh. 10,000 mAh is roughly two full charges for a modern phone. 20,000 mAh is four. But the charging speed depends on wattage, not capacity.
2. The flight limit. Airlines cap lithium batteries at 100 Wh. A 20,000 mAh bank at 3.7 V is about 74 Wh, so it flies. A 27,000 mAh bank is 100 Wh — right at the limit, and some airlines refuse it.
3. Ports. Two outputs let you charge a phone and headphones at once. USB-C in and out is now the standard; micro-USB is the sign of an older design.
4. Weight. 20,000 mAh weighs around 400 g. It is the difference between a pocket and a bag.
5. Cable or no cable. Built-in cables save you the one thing you always forget. They also break first.
Frequently asked questions
How many charges will 10,000 mAh give me?
Roughly two full charges for a modern phone, less in cold weather.
Can I take it on a plane?
Yes, in hand luggage, up to 100 Wh. A 20,000 mAh bank is about 74 Wh.
Does fast charging damage my phone?
No. The phone negotiates the rate. A higher-wattage bank charges faster only if the phone supports it.
