GCE is the newest manufacturer of portable oxygen concentrators. GCE is a British company, though the Zen-O is manufactured in Auburn Hills, Michigan, making it an American-made product. In addition to the Zen-O, GCE has just released a new 5-pound Zen-O lite which provides pulse flow up to setting 5 and is comparable to the Inogen One G3 and SimplyGo Mini.
The Zen-O has been on the market since 2016 and has proven itself to be very dependable and easy to use. Most concentrators seem to require 6 months in the marketplace to allow the manufacturer to get the bugs out; however, it appears GCE took the time to test the Zen-O prior to releasing it to the market as it has had very few issues.
The Zen-O comes standard with the Zen-O concentrator in an attractive carry bag, AC and DC adapters for home and car, one (1) rechargeable battery (with the ability to hold a second battery), and a slim mobile cart.
The Zen-O provides continuous flow up to 2 liters per minute and pulse settings up to 6, making it similar to the Philips SimplyGo, yet it is superior in many features. Most notably is the Zen-O’s dual battery slots, providing double the battery time and less-frequent battery changing. Those using the unit at pulse 2 will enjoy 8 hours of battery time with two Zen-O batteries. Taller and narrower than the SimplyGo, the Zen-O is more comfortable to carry over your shoulder and allows for a slimmer cart, making it easier to put behind your seat in the car or even between your legs. The Zen-O cart is so compact you won’t have to remove and stow it away when traveling by plane. I also like the controls on the Zen-O with its easy on/off button that does not require double inputs like the SimplyGo. And at 38 decibels, the Zen-O is enjoyably quiet. Finally, those with minimal mechanical abilities will find it easy to change the sieve columns on their own, rather than waiting for factory service.
The Zen-O is an excellent option for travelers who need oxygen at 2 LPM only at night and are unable to use pulse flow at night, including those who use oxygen with a CPAP. The Zen-O can easily be packed in your carry-on luggage for a healthy night’s sleep while traveling.
Given the oxygen output, proven reliability, dual battery slots, and ease of use, I would say the GCE Zen-O is the best portable oxygen concentrator in its class (10-pound units). And if higher oxygen levels are not needed, I would also recommend the Zen-O over larger models such as the 14-pound SeQual eQuinox, 18-pound SeQual Eclipse 5 and the 20-pound Oxlife Independence.
