DEDAKJ Portable Pulse Flow Oxygen Concentrator

A pulse flow oxygen concentrator delivers oxygen in short bursts (pulses) triggered by your inhalation. This intelligent method is more efficient than continuous flow, conserving battery and oxygen, making it ideal for active users.

The unit weighs only 1.2 kg and measures 163.5 x 100 x 184 mm, making it one of the lightest and most compact medical-grade portable concentrators available. It easily fits in the included carrying backpack or can be hand-carried.

With one 5000mAh battery, you can expect approximately 3.5 to 7 hours depending on the flow setting (see detailed chart in product description). The dual-battery option doubles this runtime, and batteries are hot-swappable for continuous use.

Yes. You can plug the device into a power outlet (using the included adapter) or a car charger for continuous use while simultaneously charging the battery.

Yes. Each individual battery is rated at 72Wh, which is under the 100Wh limit for carry-on batteries requiring no airline approval. For the two-battery pack (144Wh total), it falls under the 100-160Wh category, which is permitted by most airlines but may require prior notification—we recommend checking with your airline before travel.

At higher elevations, the air is thinner. The High Altitude Mode automatically adjusts the device's internal compressor to ensure it still produces oxygen at the specified purity (90-96%) and flow rate, effective up to 5000 meters.

It delivers medical-grade oxygen with a concentration of 90-96%. It offers 5 adjustable settings: Pulse flow levels 1-4 and a Continuous flow level 5.

The device operates very quietly, typically below 45 decibels on lower settings, making it discreet for use at home, work, or while sleeping without causing disturbance.

The package includes the oxygen concentrator, one or two rechargeable batteries (depending on the option selected), a charger, a nasal cannula, a user manual, and a premium protective transport box. The optional carrying backpack is sold separately or in specific kits.
