Inogen One G5 External Battery Charger BA-503

My husband can still use his inogen at work while the other battery is charging

Product works great

a very bit pricey, however its what I needed

Easy to use.

Very easy to use

Must have if you have a spare battery for your Inogen. Quite pricey, but works as designed.

Best price for this product.

You have to make sure plugged in the cord from wall to unit is loose fit

would buy again

Works great to recharge my inogen batteries
