One G3 External Battery Charger - Lightweight and Portable Charging for The Inogen One G3-0.12 lb. - 3.13 in. W x 2.75 in. L x 1 in. H

Does a good job

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

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.

I received this battery charger very well, safely packaged. The charger itself was also protected in Inogen's heavy-duty air bubble envelope. I intentionally ran the charge down in one regular-sized battery for my oxygen concentrator, then attached my new charger to it. My battery charged up from 3% to Full in less than 4 hours. I am very satisfied with this product.

Now I have the convenience of charging my Inogen One G3 batteries (single and double cell) not using using the POC. Charging time using the external charger is about the same time.

I put off buying this because of the cost. That was a mistake - it is so handy to have I’m amazed. Wish I bought it sooner!!

The product may be ok but the driver left the package near the street in the snow. Our driveway and steps are clean. This item is worth over $200

Works great, but way too expensive for what it is in my opinion. But when you have to have it - you pay whatever they ask.
