MENMOS Portable Home & Travel Oxygen Bar Machine

Big question about the car battery...does not work ????? Is it compatible with standars USA cars ???Machine just quit, would not stay on or function. with the car charger, anyone haveinsight on this, Please help..

Great

This machine is very well made and designed. The oxygen delivery is 90% at 1 liter per minute, 70% at 2 lpm, 50% at 3 lpm, 40% at 4 lpm, and 30% at 5 lpm. This machine fills in the needs for most people where the battery portables are expensive and run at lower oxygen levels, and the higher end machines that provide high oxygen levels but are for home use and not portable at all. This machine fits nicely in between. If you want a personal machine that is easily transportable, for your "oxygen bar" needs, this is the one to get.A secondary note: If you use a 12vDC to 120vac inverter for use in a car, use a minimum 300W Pure Sine Wave Inverter. This will give the longest life for your machine. A lesser wattage modified sine wave inverter (Really a square wave vaguely simulating a sine wave) will shorten the life of the machine - in my opinion, as an electronic technician knowledgeable in using inverters to drive electric motors.
