The Wellue is a bottle-sized pulse-dose oxygen concentrator that weighs about 4 lb with one battery. It delivers 93%±3% oxygen at settings 1–3, shown live on screen, and runs up to 9 hours on two detachable 6600mAh batteries. It suits travelers, hikers and daily commuters who need supplemental oxygen without a tank. Unlike many small concentrators, buyers report it holds above 90% purity and raises saturation at altitude, though it is pulse-only and not for continuous-flow users.

Buyers rate it highly and say it raises oxygen saturation at altitude, often from the low 80s to the low 90s on level 1. They call it lighter and more convenient than an oxygen tank and say it beats a larger, heavier unit. The main complaint is that the strap and pad will not stay where they are set.
The Wellue portable oxygen concentrator is a compact, bottle-sized unit that delivers pulse oxygen. It fits in daypack side pockets and carry-ons, and it comes with a carry bag and shoulder strap. It weighs about 4.0 lb (1.8 kg) with a single battery.
Oxygen purity is 93%±3% at flow settings 1-3, and the current concentration shows in real time on the screen. The screen also shows battery status and flow settings, and the buttons are recessed. A rotate knob selects one of five pulse flow settings. Seven safety alarms monitor conditions from airflow to battery life.
The unit has two detachable 6600mAh batteries, which give up to 9 hours of oxygen support. It charges through a Type-C connection and can run at altitudes up to 4,000 meters. It has Pulse Mode and Active Mode. Active Mode switches to timed pulses at 20 BPM if weakened breathing is detected.
