James,
I recently installed an AuraGen system [1] similar to the current listing on eBay (#330329068735) onto a customer’s Bug Out Vehicle (BOV [2]), a 1986 Chevrolet Suburban 1 ton (modified with some parts that were originally incorporated in the M1008 CUCV [3]). This customer also is afflicted with COPD [4] and uses a 110 VAC [5] Oxygen generator. The Auragen, being a military designed system is far more durable, far more rugged, and most importantly, far more versatile than an inverter placed into any vehicle electrical system. Being a mil-spec unit,.EMP [6] is also not an issue as it meets the military requirements for such use in medical units for power generation.
At around $1,700 on eBay the end user can add about another $500-to-$600 for install and miscellaneous parts. I personally have a PTO [7] drive system in my own vehicle and have used it in several situations where, as some say “The Schumer [8] has hit the rotating impellers”, LOL [9], powering some mission critical communications, networking, and telecom facilities for other NGO [10] customers. These are not cheap, but what price is reliable power when lives depend on it? Best Regards, – Bob S.
