✔️ Backpackers – Ultralight alternative to camp stoves
✔️ Parents – Prepare bottles on road trips
✔️ Office Workers – Ditch breakroom germs
Critical Note: Not for heating milk/oil – water only! For best results:
Use filtered water (reduces scaling)
Choose USB-C PD models >45W (faster boiling)
Avoid sub-$25 units (safety risks)
The Bottom Line: A game-changer for anyone needing hot water untethered from outlets. While not powerful as full-sized kettles, its convenience outweighs limitations for on-the-move lifestyles.
