Inogen One G5 External Battery Charger BA-503

Could not charge batteries while it was still attach to the concentrator. This little charger is a life saver, because they will now recharge.

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!!

Surprising light, nice indicator light, but over priced. The bad thing is they are the only ones that have this pin layout and form-factor for the charger, so they get to overcharge the handy capped. Would I buy again: yes because I need to be able to charge my batteries.

Used to charge spare battery. Works great.

It’s great. Easy to use. Totally silent. Charges pretty quickly and it’s small.

Best price for this product.

Easy to use.

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.

Got this to charge spare batteries, it charged the battery better than the regular charging method.. Really like this charger .

Charges G5 battery without having to keep concentrator plugged in!
