Power base
Designed primarily for outdoor use, the Storm4 X-plore is unbeatable in this regards. It offers improved shock absorption and improved traction over even rough ground, giving you maximum freedom to go where you choose. Each wheel has independently adjustable high-end springs that can be set to your individual needs. The X-plore features the latest Durawatt motor technology, providing a smoother, quieter drive that delivers on power and performance, as well as an unrivalled 37 mile range at a top speed of 8 mph. When it comes to driving outdoors, the Storm4 X-plore goes further, faster, and in more comfort than its rivals. It features additional 50 mm all-round suspension over the basic Storm4 model at a minimal cost increase, making it the obvious choice.
Seating
Invacare's top of the range Modulite seating system can be fitted to the Storm 4, allowing postural support and comfort that can be set exactly to your size and needs. Powered accessories such as a seat lifter, powered tilt and recline, and powered elevating leg rests are all available, as one would expect from such a high-end powerchair. The modular nature of this seating system also allows retro-fitting of accessories and further adjustment at a later date, should your requirements change.
A Teens Modulite version is available for younger users, in seat widths of 12 - 15" and depths of 12 - 22", to accommodate the body shape of adolescents.
There is also the option for a Recaro seat on the Storm, although this is more expensive than the Modulite seat.
Transportation and Options
Fully crash-tested, the Storm4 X-plore is suitable for occupied transportation in an adapted vehicle, and is compatible with the Dahl docking station. The backrest can be easily folded down to lower the overall height for storage or unoccupied transport, allowing it to fit in a wider range of vehicles. Further customisations include a choice of solid or pneumatic drive wheels and castors, as well as six different shroud colours available as standard.
Controls
The LiNX Simply Smart control system is now available on the Storm4 X-plore, easy to use, and highly expandable with a range of options such as high definition LCD screens. LiNX controls also allow easy post-supply adjustments should your control needs change, and can be fitted with a range of special controls.
Our verdict
The Invacare Storm4 X-Plore Powerchair is the ultimate choice for those after a high performing outdoor powerchair that makes no compromises on range, speed or comfort.
The Storm is of limited use indoors, unless you have a particularly spacious property, as it is not as compact as other powerchairs, and rear-wheel drive results in a large turning circle. You may also find that if you've been off-roading, the tyres are too muddy to want to bring indoors!
If you want a balance of indoor use along with outdoor performance, than Invacare's Aviva RX40 is the powerchair to consider instead; otherwise if you're looking for off-road capability then Meyra's Optimus2 is worth trying alongside the Storm.
