Portable Air Conditioner for Camping, with only a single duct, suffers from extremely low energy efficiency. While cooling, it simultaneously creates negative pressure due to exhaust, drawing in hot outside air and creating an endless cycle. For poorly insulated vans, it only provides a noticeable breeze, failing to substantially lower the overall temperature.
The Portable Air Conditioner for Camping is a large cabinet occupying approximately 0.25 square meters and half a meter high, plus a bulky exhaust duct that cannot be bypassed. Inside a van, it becomes a permanent obstruction, severely disrupting the layout and flow of movement.
A portable air conditioner can exist as a “temporary toy” rather than a “living space” if all of the following conditions are met
1. It is only used when parked at a campsite with 220V AC power, completely independent of its own battery.
2. It is only used for mild, supplementary cooling during spring and autumn or at night when temperatures are already low; it is not expected to work during the midday heat of summer.
3. The user can tolerate its significant noise and space occupation.
4. The user has extremely low expectations for its cooling performance.
“Portable air conditioners” and “minivan/RV” systems fundamentally contradict each other. While they address the pseudo-pain point of “no installation required,” they introduce four unavoidable real pain points in RV living: extreme power consumption, poor performance, space-consuming nature, and high noise levels.
Immediately remove “portable air conditioners” from your primary solution list. They will waste your valuable money and space and provide an extremely poor experience.

The correct approach to converting a minivan into an RV should be
1. Prioritize thorough insulation and heat preservation throughout the vehicle. This is the foundation for any effective air conditioning system.
2. Secondly, plan the electrical system according to your travel patterns (whether you frequently stay at campsites, and the frequency of summer use).
3. Finally, within your electrical system budget, choose the most efficient dedicated cooling solution.
The essence of adaptability is system matching. Choose an air conditioning system for your minivan that matches its limited space, limited power, and mobility, rather than forcibly cramming in an inefficient portable air conditioner designed for fixed rooms.
