Cybertake S2 Pro Portable Air Conditioner vs CYBERTAKE S1 Pro Portable Air Conditioner

The S2 Pro is the stronger unit: a Panasonic inverter compressor, 1800W heating, 5100 BTU peak cooling, 240 CFM airflow and a 150 sq ft rating. The S1 Pro is smaller and lighter at 21.6 lb, but it is cooling-only at 3300 BTU with a 120 sq ft rating. Buy the S2 Pro for year-round use in an RV, truck or tent; buy the S1 Pro only if you want the lightest possible cooling box for a small space. Owners of the S2 Pro praise the fast cooldown and quiet Eco sleep mode; the S1 Pro draws more modest feedback and its listed heating figure is not backed by a heater spec.

• Choose the Cybertake S2 Pro if you need heat as well as cooling, run it from 12V, 24V, 48V or wall power, and want the fastest cooldown in a 150 sq ft space.
• Choose the Cybertake S1 Pro if you only need cooling, want the lighter 21.6 lb unit, and are cooling a tent, cab or small room of about 120 sq ft.
