Take the strain off pushing a manual wheelchair with the Duo Wheelchair Powerpack. Enjoy the effortless transportation that the powerpack provides with no more struggles up hills, ramps or uneven surfaces. The powerpack fits to the back of most manual wheelchairs and is operated by the flick of a switch that is fitted to the push handles. Simply walk behind with your thumb on the switch and let the powerpack do the hard work for you. The powerpack is easily removed for charging and travel, and it's lightweight, so it can be transported in the boot of a car, or on public transport.
