20,000 mAh Power Bank

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). Prices range from PLN 50 for Dudao/Romoss to PLN 150 for Baseus/Ugreen models with PD 45 W.

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.
