Inogen One G5 External Battery Charger BA-503

I have a portable oxygen (Inogen) and it has to be charged

Purchased to keep my batteries ready to go. Expensive but worth it because I always have a battery to go and since Im using oxygen 24-7, this is a valuable asset!!

It charges fast and is light to carry with you.

My sister-in-law needed extra battery packs for going outside and for when the power was out in her building. So happy to have this extra insurance.

Best price for this product.

First unit was damaged but supplier sent new one immediately ,arrived the next day .

A must have if you have multiple batteries. You all ways have a full charged battery ready to go. It also saves the Inogen 5 from charging for hours.

Very lite and easy to charge batteries .

would buy again

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