👎 Cons

- Charging the power bank itself can take a few hours, depending on the adapter used.
- Not laptop-grade output — won’t run larger power-hungry devices.
Keeping realistic expectations helps you avoid disappointment—this is designed for phones and small electronics rather than heavy devices.
