10,000 mAh power bank — compact enough for your pocket
10,000 mAh is a typical capacity for compact power banks — it weighs 200–300 g and fits in a trouser pocket or a small bag. It charges a flagship smartphone with a 5,000 mAh battery from 0 to 100 % with 30–50 % left over. Recharging the power bank itself takes 3–5 hours with an 18 W charger.
Who is it for
- Everyday use — one top-up during the day when the battery drops in the afternoon
- Air travellers — 37 Wh is well below the IATA limit (100 Wh), zero issues at security
- iPhone MagSafe users — MagSafe 5,000–6,000 mAh models snap magnetically onto the phone
What to look for
Choose models with USB-C PD 20 W — fast charging for the phone and the power bank itself. A USB-A port lets you charge older devices at the same time. Models with an LED display show the exact battery level. At homescreen.pl: Baseus, Dudao, Joyroom, Romoss, Samsung.
