It takes about 4-5 hours for full charging. The light on the battery charger will turn green once full charged.

The normal respiratory frequency is 18-26 times per minute, and lovego g3 preset a max 42 times per minute in pulse flow mode. So if your respiratory frequency is more than 42 times, then resjoy g3 alarm system works with code “E4Hb”. So you only need to adjust your breathing,not too fast.

We do not suggest that. As it may damage the machine.

Taking oxygen too long, your nose may feel very dry. And the oxygen through the humidifer bottle will be humidied which makes oxygen therapy more confortable.

Take Oxygen Anytime, Anywhere.
