Based on ratings from across the web.
Reviews last updated: August 2026 · How we calculate this

What we like about Maxesla SKY-1B-FR

  • Efficiently cools down small rooms, offices, and bedrooms during heatwaves
  • Equipped with functional wheels and built-in side handles for easy mobility
  • Provides versatile 4-in-1 utility including cooling, fan, sleep, and dehumidifying modes
  • Includes an integrated 24-hour programmable timer
  • Effective dehumidification performance that extracts noticeable amounts of water

What we don't like about Maxesla SKY-1B-FR

  • Operates with high noise levels, described by some as sounding like a jet engine
  • The placement of the digital display screen on top makes settings hard to read from a distance or when using the remote
  • The standard exhaust hose is prone to disconnecting frequently
  • The remote control comes with cheap stock batteries that are prone to leaking and causing corrosion
  • The unit is somewhat heavy and cumbersome to carry up and down stairs

Verdict

The Maxesla SKY-1B-FR is a portable 4-in-1 air conditioner offering a 9,000 BTU cooling capacity powered by a 2.6 kW rotary scroll compressor running on eco-friendly R290 refrigerant. Operating on a 220V power supply, this Class A energy-efficient unit effectively cools indoor spaces up to 215 square feet while doubling as a dehumidifier and multi-speed ventilation fan. Main advantages include highly mobile design features like 360-degree casters and dual hidden handles, paired with user-friendly conveniences like an LED digital display, a 24-hour programmable timer, and a dedicated low-noise sleep mode operating at 54 dB. However, notable drawbacks include its restricted effectiveness in spaces larger than 215 square feet, potential disruption for sound-sensitive users, and reports of a rigid or short exhaust hose that can complicate window installation.
