A 20,000 mAh power bank is the all-rounder: it charges a modern phone about three times, rides in a bag on the MTR and still fits the airline limit. These are the fast-charge units shoppers in Hong Kong order most on AliExpress.
Do not shop on the biggest number alone. Look for a stated mAh figure, 20W or higher USB-C output with PD, a digital display and plenty of recent reviews with real photos. 手機冇電唔使驚，but pick a unit you can trust in your bag.

What to look for in a 20,000 mAh power bank
Start with the title. A real listing states the capacity (20000mAh), the maximum output in watts (22.5W, 30W, 45W) and the protocol (PD, QC). A USB-C port that both charges the power bank and charges your phone saves carrying a second cable.
A digital display is worth having because it shows the real percentage instead of four vague lights. Expect a unit of this size to weigh around 350 g to 450 g, so check the weight before you commit to carrying it every day.
Is 20,000 mAh too big for daily use?
For a daily commute to the office, probably yes: a 10,000 mAh slim unit is lighter. A 20,000 mAh model makes more sense when you travel, spend a long day out, charge a tablet, or share one power bank between two people. At about 74Wh it stays well under the common 100Wh airline limit.
Frequently asked questions常見問題
How many times can a 20,000 mAh power bank charge a phone?
Around two and a half to three full charges for a typical 4,500 mAh phone, because roughly 60% to 70% of the rated capacity is usable after conversion losses.
Is 22.5W fast enough?
It is fine for most Android phones and gives iPhones a decent top-up. For tablets or faster phone charging, look for 30W to 45W with PD.
Can I take a 20,000 mAh power bank on a plane?
Yes, in hand luggage. 20,000 mAh at 3.7V is about 74Wh, under the common 100Wh limit. Never pack it in checked baggage.
