What to Look For
- USB-C in/out: One cable for everything (bank + phone). Avoid micro-USB if possible.
- Wattage: 18–22.5W is the sweet spot for fast phone charging without overheating.
- Size & weight: Pocketable ≈ 180–220g. Ultra-slim models trade a little speed for thinness.
- Indicators: A simple % readout or clear LEDs help you avoid heading out half-charged.
- Safety marks: Look for UKCA/CE compliance from known brands and UK-based support.
Quick Tips
- Use a decent USB-C cable rated for fast charge (PD/20W+).
- Charging while in a tight pocket can trap heat — give it airflow.
- Upgrade your wall charger too: a small 20–30W USB-C plug will refill the bank faster.
- Air travel: 10,000mAh is well under airline limits — keep it in hand luggage.
