20,000 mAh power bank — the universal choice
20,000 mAh is the sweet spot — enough capacity for a weekend trip (3–4 smartphone charges), under 500 g and hassle-free on planes (approx. 74 Wh, well below the 100 Wh limit).
Who is it for
- Weekend getaways — 3–4 smartphone charges, 1 tablet charge
- Students and mobile workers — a full day away from an outlet
- Travellers — fits in carry-on luggage with no restrictions
What to look for
Choose models with USB-C PD 20–30 W (fast phone charging) and a USB-A output (for older devices). Recharging the power bank itself takes 5–8 hours with an 18 W charger. At homescreen.pl: Baseus, Ugreen, Joyroom, Dudao, Romoss, 4Smarts.
