Review on Inogen SG_B00D9BU4IK_US One G3 Backpack by Danielle Rogers

Perfect for my dad when he needs to be outside. Comfortable to carry on one or two shoulders. Most of the time he runs errands in the city, for example to the doctor, to the post office or to the grocery store. He leaves his charger in the car so he can plug it in between stops if needed. On these short trips, combined with the use of a charger, he does not need to carry an extra battery and the bag is therefore much lighter. His Inogen One G3 is provided by Medicare, so if you bought it outright it came with two 4-hour batteries instead of a 4-hour and an 8-hour battery. It also contributes to lighter weight when carrying an extra battery. Remember that just because you're taking a second battery with you as a backup, you shouldn't take it with you unless the battery dies first. You can always take out the extra battery and leave it in the car for quick reference when you need it. Another thing that worked really well for my dad with this backpack. A few years ago he injured his shoulder and is in severe pain every day. Although the Inogen One G3 is lightweight, it still gets a bit heavy if you end up having to carry it with a shoulder strap or arm strap after a while. The beauty of a backpack is that when the weight gets too much, it throws it over one shoulder. He just carries it like a real backpack and he distributes the weight evenly. We are very happy with the purchase!
