04Questions buyers ask
What is a mosquito net air conditioner?
A small air conditioner that cools the space inside a bed's mosquito net or a small tent instead of a whole room. The COG-2 delivers 3000BTU for 5–8 m²; in a larger room, use it with an air-conditioning mosquito net or a tent.
What is the difference between the COG-2 and the COG-2+?
The COG-2 is cooling only. The COG-2+ adds a heating mode with 2000BTU of heating capacity. Both cool at 3000BTU from 300W.
Does the COG-2 need a drain hose?
Yes. A drain hose and an exhaust hose come in the box.
Can I control the COG-2 from my phone?
Phone and WiFi control through the Uhome Life app is available as an option. The panel and the remote control work on every unit.
Can the COG-2 run on 12V or 24V?
It runs on AC 220V / 110V; from a 12V, 24V or 48V battery it needs an inverter. At 300W rated power it has the lowest draw of the four SpaceCool models.
Is the COG-2 available for OEM / ODM?
Yes. Orders with custom packaging start at 100 units; without customization there is no minimum.
