How to choose a power bank or charger
- Capacity: 10,000mAh suits most people. Go to 20,000mAh only if you charge more than one device a day.
- Output: a higher wattage charges faster, but only if your phone supports it.
- Ports: USB-C is now standard. Check you have the right cable.
- Weight and size: a bank you do not carry is no help.
- Brand and warranty: a known brand with a written warranty is safer than a no-name bank.
