Buying Guide: Key Considerations for Choosing a Water Irrigator
- Intended use: Travel-friendly vs. home-use needs. A compact model with long battery life suits commuters, while higher-capacity tanks favor daily home use.

- Power and charging: USB-C or standard USB charging adds convenience for travelers. Verify compatibility with your power sources.
