Our verdict

The Wave 3 is a different animal to mains-only rivals: with the optional battery it runs cordlessly for hours, making it ideal for tents, vans, campers and off-grid rooms. Genuinely quiet (down to 44 dB) and doubles as an efficient heat pump, but cooling output is modest for the money and it is expensive once you add the battery.

Pros

  • True cordless running with optional add-on battery
  • Very quiet, down to 44 dB in sleep mode
  • Compact and genuinely portable at ~15kg

Cons

  • Expensive, especially with the add-on battery
  • Modest 6,100 BTU cooling suits only small spaces
