Overview
The HKM-400787 is a compact folding electric wheelchair designed for adults who need reliable powered mobility at home, in shops, and on paved outdoor paths. Its aluminum alloy frame keeps the overall weight manageable while supporting a 265 lb load capacity, and the scissor-style folding mechanism lets it collapse quickly for loading into a car trunk or closet. Padded armrests, a breathable fabric seat, and an adjustable backrest help you stay comfortable during longer outings.
Dual 250 W brush hub motors drive the rear wheels for smooth acceleration and enough torque to handle ramps and gently sloped sidewalks. The 24 V lithium battery system uses two removable 12 Ah packs, so you can charge them on or off the chair and carry a spare set for extended days out. Depending on terrain, speed, and occupant weight, the chair can travel up to approximately 12.4 mi (20 km) on a single charge.
A 360-degree joystick controller is mounted on the left armrest by default and can be swapped to the right side if you prefer. The controller offers speed selection and a horn, while the electromagnetic brake engages automatically when the joystick returns to center or the power is released. Solid front caster wheels and larger rear drive wheels with a treaded tire pattern keep the chair steady over tile, carpet, asphalt, and compact gravel.
Safety features include rear anti-tip wheels, a seat belt anchor point, reflective panels, and a manual brake release lever for attendant-controlled pushing. The chair folds without tools by pulling the backrest release, and the footrest flips up to reduce the folded depth. With folded dimensions of 29.5 x 15.0 x 29.1 in, the HKM-400787 fits into most sedans and SUVs for travel to appointments, parks, or family visits.
Key Features
Lightweight Aluminum Frame
The HKM-400787 uses an aluminum alloy frame that resists corrosion and keeps the chair light enough for travel. Welded joints and a scissor-style fold provide rigidity when open and a slim profile when collapsed. The red-and-black finish hides everyday scuffs and is easy to wipe clean.
Dual 250 W Brush Hub Motors
Two 250 W brush motors mounted in the rear hubs deliver a combined 500 W of power. They accelerate smoothly on flat floors and provide enough torque for ramps and modest slopes. The hub-mounted design reduces the number of exposed moving parts.
Removable 24 V Lithium Battery System
The chair runs on two 24 V 12 Ah lithium battery packs that slide out from under the seat. You can charge them on the chair or remove them for off-board charging in a more convenient outlet. Carrying a second set doubles your available range for all-day trips.
Electromagnetic Braking System
An electromagnetic brake activates automatically when the joystick is released or the power is turned off. This keeps the chair stationary on inclines and prevents unintended rolling. A manual release lever lets an attendant push the chair when needed.
360-Degree Joystick Controller
The joystick controller offers intuitive direction control and speed selection for precise maneuvering in tight spaces. It can be mounted on either the left or right armrest to suit your dominant hand. A horn button and battery-level indicator are built into the control head.
Quick-Fold Travel Design
Pull the release strap on the backrest and the chair folds inward without tools in seconds. The footrest flips up and the armrests lift to reduce the folded footprint. Once folded, it stands on its rear wheels and fits into many car trunks.
All-Day Seating Comfort
A padded fabric seat and backrest cushion the rider during extended outings. Flip-up padded armrests make side transfers easier, and the adjustable footrest supports your legs. The seat dimensions are approximately 18.1 in wide by 16.5 in deep.
Safety and Stability Features
Rear anti-tip wheels, a seat belt, and reflective details add peace of mind on ramps and uneven paths. The wide rear drive wheels and front caster pair keep the chair balanced across indoor floors and paved outdoor surfaces. A battery compartment lock helps deter theft while parked.

Battery, Range, and Charging
The HKM-400787 is powered by two removable 24 V 12 Ah lithium battery packs mounted under the seat. Together they provide 24 Ah of capacity and approximately 576 Wh of energy for a driving range of up to 12.4 mi (20 km) under ideal conditions. The included off-board charger accepts 100-240 V AC input, so it works with standard household outlets.
You can charge the packs while they are installed or remove them for charging indoors. Each pack has a handle for easy carrying, and a locking tab keeps it secure while driving. Battery life is rated for 500 or more charge cycles before noticeable capacity loss occurs.
Tip: For longest battery life, store the packs at room temperature and avoid leaving them fully discharged for more than a day or two. Recharge after each use and keep them away from direct sunlight, heaters, and freezing conditions during storage.
Because the batteries slide out, you can leave the folded chair in a vehicle and charge the packs inside your home, office, or hotel room. This also makes it simple to carry a spare pair for extended travel.
Daily Use & Care
- Charge the battery packs after each outing so the chair is ready for the next day.
- Release the electromagnetic brake only when you intend to push the chair manually.
- Keep the joystick dry and wipe it down if you drive through light moisture.
- Check tire pressure on the rear pneumatic tires weekly for the smoothest ride.
- Fold the chair before lifting it into a vehicle to protect the frame and joystick.
- Use the anti-tip wheels on inclines and uneven ground for added stability.
- Store the battery packs indoors at room temperature when not in use for long periods.

Frequently Asked Questions
What is the weight capacity of the HKM-400787?+
The HKM-400787 supports riders up to 265 lb (120 kg). Exceeding this limit can reduce range, climbing ability, and braking performance. Always include the weight of any bags or accessories you carry.
How far can the chair travel on one charge?+
On level ground with a typical rider, the chair can travel up to 12.4 mi (20 km) on a full charge. Range decreases on hills, rough surfaces, and in cold weather. Carrying a second battery set can extend your outing.
Can the batteries be charged off the chair?+
Yes, both 24 V 12 Ah lithium battery packs slide out and can be charged separately with the included off-board charger. This is convenient when storage space is limited. A full charge takes approximately 6 to 8 hours.
Is the joystick controller interchangeable between sides?+
Yes, the joystick mount can be installed on either the left or right armrest. This lets left- or right-handed users operate the chair comfortably. The swap requires only a few minutes and basic tools.
Does the chair have a manual mode?+
Yes, a manual brake release lever disengages the electromagnetic brake so an attendant can push the chair like a standard wheelchair. Use this only on level surfaces and with assistance. Always re-engage the brake before powered use.
What surfaces can the HKM-400787 handle?+
The chair is designed for indoor floors, paved sidewalks, compact gravel, and short grass. Its 12 in rear drive wheels and front casters smooth out small bumps. It is not intended for loose sand, deep gravel, or off-road trails.
Can I take this wheelchair on an airplane?+
The removable lithium battery packs are typically sized for airline travel, but each carrier sets its own rules. Contact your airline before your trip to confirm battery limits and packing requirements. Never check the batteries in hold luggage.
How do I maintain the chair?+
Keep the battery charged, wipe the frame with a damp cloth, check tire pressure on the rear pneumatic tires, and inspect fasteners monthly. Store the batteries indoors at room temperature. Follow the user manual for specific service intervals.

Why Choose the HKM-400787
Folds for Any Car Trunk
The quick-fold mechanism collapses the HKM-400787 to 29.5 x 15.0 x 29.1 in, so it fits in most sedans and SUVs. This makes it practical for appointments, family visits, and vacations.
Removable Batteries
Two slide-out 24 V 12 Ah packs let you charge inside your home while the chair stays in the garage. A spare pair can double your daily range.
Smooth Dual-Motor Drive
Dual 250 W brush hub motors provide a combined 500 W of power for ramps, carpets, and paved paths without jerky starts.
Intuitive Joystick Control
A 360-degree joystick can be mounted on either armrest and offers speed selection for tight indoor turns and open outdoor stretches.
Built-in Safety Braking
The electromagnetic brake holds the chair on inclines the moment you release the joystick, while rear anti-tip wheels add stability.
Airline-Friendly Battery Option
Each removable lithium pack is sized for common airline battery allowances, making travel easier. Confirm your carrier's rules before flying.
Controls & Indicators
360-Degree Joystick
Move the joystick in the direction you want to travel; speed increases with how far you push it. Release the joystick and the chair slows to a controlled stop. A horn button is located on the control head for alerting others.
Power Switch
Turn the keyed power switch to the ON position to activate the controller and motors. Always switch the chair off before folding, lifting, or charging. Remove the key when leaving the chair unattended.
Speed Selection
Press the speed button on the joystick to cycle between low, medium, and high speed settings. Use the lowest setting indoors and around obstacles. The selected speed is shown on the control display.
Electromagnetic Brake
The brake engages automatically whenever the joystick is centered or the power is off. This prevents the chair from rolling on slopes. A manual release lever disengages the brake for attendant pushing.
Battery Release
Unlock the battery compartment and slide each pack out to charge it away from the chair. Reinsert the packs until they click into place and the indicator lights confirm connection.
Charge Port
Plug the off-board charger into the charge port on the battery pack or control module. The charger works with 100-240 V outlets and shows a full-charge indicator when complete.
Anti-Tip Wheels
The rear anti-tip wheels make contact with the ground if the chair tips backward on a ramp. Check that they spin freely and are not worn before each ride.
Pre-Ride Safety Checklist
- Inspect the frame for cracks, bent tubes, or loose fasteners before each ride.
- Confirm both battery packs are locked in place and the charge indicator shows adequate power.
- Test the joystick in all directions at low speed before leaving a level surface.
- Verify that the electromagnetic brake engages when the joystick is released.
- Check that the rear anti-tip wheels rotate freely and are not damaged.
- Make sure the footrest is folded down and your feet rest securely on it.
- Fasten the seat belt and adjust it so it sits low across your hips.
- Ensure the tires are not worn or under-inflated before driving outdoors.
Quick Troubleshooting
Chair will not power on.+
Check that both battery packs are fully seated and the key switch is turned ON. Verify the charger is unplugged from the chair. If the display remains dark, test each battery pack individually.
Joystick does not respond.+
Make sure the joystick cable is securely connected to the controller. Restart the chair by turning the power off and on. If the problem continues, inspect the cable for damage.
Chair pulls to one side.+
Check the rear tires for equal pressure and wear. Verify that both motors engage by testing forward movement on a flat surface. Contact support if one motor fails to run.
Brake does not hold on slopes.+
Confirm the electromagnetic brake is not manually released. Test on a slight incline with the power off; the chair should resist rolling. If it slides, stop using the chair and have the brake inspected.
Range seems shorter than expected.+
Range drops with hills, colder temperatures, heavier loads, and older batteries. Charge the packs fully and avoid frequent high-speed driving. Replace batteries when they no longer hold a charge.
Folding mechanism sticks.+
Remove any debris from the hinge points and apply a small amount of silicone lubricant. Check that the backrest release strap is not caught. Do not force the frame closed.
