12 Volt No-Idle Air conditioning System for Trucks/Vans:  >>>[email protected]
The battery-powered Guchen no-idle HVAC system saves fuel, keeps drivers comfortable and helps protect the environment.

It seems that there's an ongoing quest in some circles for the holy grail of boating comfort: 12 volt air conditioning. 

Both models' Btu output is specified at ABYC rating conditions, and both come from well respected manufacturers. There are other 12v DC compressor - based units available, but either their specifications and documentation give insufficient information, or they are not suitable for small marine applications.

It seems that there's an ongoing quest in some circles for the holy grail of truck cab comfort: 12 volt truck air conditioning. Yet few seem to fully appreciate the benefits of the more practical, but far less complex and substantially less expensive alternative: DC powered 12v rooftop air conditioner. Many trucks these days already have drivers installed, and if not, there's a wide range of inexpensive models available that are suitable for powering small air conditioners.

This post will focus on small air conditioning systems that are suitable for sleeping cabins or for truck sleeper cab. With a small unit, the DC current draw is low enough that they can usually be powered by an engine alternator whenever the engine is running, as well as from the batteries when required. Of course, any sized air conditioner can be powered by batteries through an inverter, it is just a matter of practicality.
