One of the hardest things about taking your young child with you when you do errands is dealing with the stroller. The Origami Stroller from 4Moms opens and folds itself at the touch of a button, so you don’t have to fight with it yourself. One of the wheels has a generator inside to keep the battery charged up; one short walk is enough to keep the battery charged, or you can charge it with AC power. (You can also fold it manually). It has safety features: seat sensor so it won’t fold when a child is in the seat, a 2-step fold process so you don’t start it accidentally, daytime “running lights” so other people see you, and pathway lights so you can see your way in dim lighting. The generator even produces enough power to charge your cellphone (requires an optional accessory). An LCD display shows you the status of the battery and even shows how far you’ve walked. The Origami Stroller is $849.99, and optional color seats are $99.99 each; both are available now. You can pre-order the cellphone carry bag and charger for $39.99 or the Graco car set adapter for $59.99.
