## Questions & Answers

**Q: Will this charger also work for an Oxygo battery which look exactly the same?**
A: I would ask the manufacturer for sure but you are right they are look alike I do not sell that model however their distributed should be able to tell you I can ask Imogene in the am if you wish without asking I wouldn't want to steer you wrong

**Q: Does the battery have to cool before using the external charger? If I don't cool it, the red light blinks and it never charges!**
A: You must have a defective battery. Mine never get that hot while in use or charging. Call Imogen and they will send you a new one

**Q: Is there a warranty?**
A: The Inogen One G3 External Battery Charger comes with a 1 year warranty from Inogen. In my years of doing this, I don't think I've made more than a handful of warranty claims on the external battery charger. It's very well made!

**Q: Does this charger work with the Oxygo ?**
A: Yes, it will work with the Oxygo as well.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Battery charger
*by W***. on December 29, 2025*

Does a good job

### ⭐⭐⭐⭐⭐ Inogen best
*by A***I on November 19, 2025*

Works great if you have the 8 hr batteries you need this charger it works the best than putting battery in unit to charge!

### ⭐⭐⭐⭐⭐ Overpriced
*by S***T on October 7, 2022*

Now it was about $50 cheaper than off the Inogen website. In my opinion $250 for a charger is a rip off. I will say it’s been so handy! I have all my batteries charged and it’s very easy to use. I’m still mad about price though.
