A mobile charger is especially useful when:
✔️ You want to charge flexibly
- on the go (e.g., while traveling)
- at friends' places or at work
✔️ You don't want a fixed installation
- rental apartment
- lack of approval for a wall box
✔️ You want to save costs
- no installation costs
✔️ You use multiple charging locations
- one device for different locations
👉 A fixed wall box is better if you want to charge permanently at home with maximum power and comfort.
