Overview
HKM-5337555 is built around a lightweight aluminum alloy frame that folds in about three seconds, so the chair can travel with you rather than being left in the hallway. The two 250 W brushless hub motors deliver a combined 500 W of driving power through a 360 degree joystick, and the electromagnetic brake stops the chair as soon as the joystick is released. The frame is rated for users up to 265 lb, so daily trips to the market, the clinic, and the park feel settled at any speed.
A pair of 24 V 6 Ah lithium battery packs slide out from the lower frame tubes for off-board charging, which is convenient for hotels, offices, and small apartments without a power outlet near the chair. Each pack can be charged separately, and the dual-port charging cradle lets you top off both packs at the same time. On a full charge the chair reaches the 12.4 mi range mark at a measured 3.7 mph on flat pavement, with shorter distances on hills, grass, and thicker carpet.
Ride comfort comes from a cushioned mesh seat and a breathable backrest, both covered in a washable fabric that breathes through summer afternoons. The armrests lift up so you can slide closer to a dinner table or transfer to a car seat without leaning on the controller. A fold-up footrest with a non-slip tread keeps feet planted over uneven sidewalks, and the rear anti-tip wheels quiet the chair when you back up onto a threshold.
Travel is part of the design: the folded footprint slips into most car trunks, rides on trains, and the dual 24 V 6 Ah battery pack is sized for airline carry-on rules that vary by carrier. Call the airline in advance for their current documentation, and pack the charger lead in the chair bag. Storage, charging, and transport all point at the same idea - one chair, three places, no lifts required.
Key Features
Foldable Aluminum Frame
The chair folds in a single motion using the cross-brace under the seat, and the aircraft-grade aluminum frame keeps the folded shape rigid for trunk loading. The folded footprint is small enough to stand in a hallway while you grab the charger.
Dual 250 W Brushless Motors
Two 250 W brushless hub motors sit inside the rear wheels, so the chair has no exposed chains or belts to snag on door frames. Together they deliver 500 W of combined driving power, with the second motor assisting on ramps and on uneven sidewalks.
Dual Removable Lithium Batteries
Two 24 V 6 Ah lithium battery packs slide out from the side tubes of the frame, so each pack can be charged separately or carried indoors for a top-up. The combined 24 V 12 Ah capacity extends the daily range to 12.4 mi on flat ground.
Electromagnetic Safety Brake
The electromagnetic brake engages the moment the joystick returns to center, so the chair holds its position on slopes and flat floors without a parking lever. The brake releases again as soon as the user nudges the joystick forward.
360 Degree Joystick Controller
The 360 degree joystick mounts on the right armrest by default and can be moved to the left armrest without tools. The controller carries the power button, the speed selector, the horn, and a USB charging port for a phone.
Lift-Up Armrests and Fold-Up Footrest
Both armrests lift up to give the user a clean side path for side transfers to a bed, a car seat, or a dining table. The fold-up footrest closes against the front frame so the chair is shorter when folded and easier to stand near.
Washable Breathable Seat
The cushioned seat and the backrest are covered in a breathable mesh fabric that lets air through during outdoor use. The covers unzip for washing, so crumbs, sidewalk dust, and pollen lift out in a single laundry cycle.
Built for Travel
The folded chair fits most car trunks, ride-share trunks, and closet corners, and the dual 24 V 6 Ah packs are sized for airline carry-on rules that vary by carrier. Call the airline in advance for their current documentation and label requirements.

Battery, Range, and Charging
HKM-5337555 runs on a pair of 24 V 6 Ah lithium battery packs, one in each lower frame tube, and the pairs are wired to deliver a combined 12 Ah at 24 V. On a full charge, with a 165 lb user, flat pavement, and the seat at room temperature, the chair reaches the 12.4 mi range mark at the 3.7 mph top speed. Hills, thick carpet, grass, and heavier users will reduce the daily range, so plan a shorter loop when the route is rough. The removable packs also let you swap one pack for a spare at lunchtime, which is helpful on long museum days or at a busy airport.
Charging is handled by the 24 V 2 A charger in the box, with an input range of 100-240 V AC at 50-60 Hz so the same charger works in the United States, Canada, Mexico, and most of Europe. Plan on 6 to 8 hours for a full charge from empty, and top off the packs after each outing rather than running them to empty. The charger has a power-off protection function, so the charger stops on its own once the packs are full and the green ready light is on. Each pack is rated for 500+ charge cycles, which is roughly two to three years of daily use before a pack holds noticeably less charge.
Tip: Store the packs at room temperature, charge them once a month during long storage, and wipe the battery terminals with a dry cloth before sliding the packs back into the frame. Avoid leaving the packs in direct sunlight or in a freezing car overnight, and the cells will keep their full range for years.
The dual-port charging cradle lets you charge both packs at the same time, so the chair is ready to go after a single overnight charge. You can also charge one pack in the chair and the other on a kitchen counter, which is helpful in a small apartment without a power outlet near the chair.
Daily Use & Care
- Charge the battery packs after each outing rather than waiting until they read empty, and the cells will last longer and stay ready for the next morning.
- Lift the armrests before you scoot to a table or counter so the controller is not pressing into the edge of the worktop.
- Switch the red motor clutches to manual mode before pushing the chair by hand, and switch them back to electric mode before turning the joystick on.
- Keep the cushioned seat and breathable backrest cover free of crumbs by brushing the mesh fabric weekly with a soft bristle brush.
- Wipe the joystick and the USB charging port with a dry cloth after rain or a damp sidewalk so grit does not collect around the controls.
- Fold the chair before lifting it into a car trunk, and pull the frame together using the center strap rather than the armrests.
- Park the chair on flat ground when you stop, and rely on the electromagnetic brake instead of chocks or blocks to hold it in place.

Frequently Asked Questions
How much does the HKM-5337555 weigh?+
The chair weighs about 67.5 lb (30.6 kg) with both 24 V lithium battery packs installed, and roughly 63.9 lb (29.0 kg) with the packs removed. The folded shape is short enough for one adult to lift into a car trunk, and the cross-brace gives a solid handhold for the lift.
Do I need to charge the battery before the first ride?+
Yes, top up the 24 V lithium battery packs for a few hours before the first outing. The first three rides should be short so the cells can settle into their working range, and the charger indicator will turn green when the packs are full.
Can the chair climb a small ramp?+
Yes, the dual 250 W brushless motors drive the chair up to an 8 degree slope on a paved ramp with a 265 lb user. Steeper ramps will still roll, but the 3.7 mph top speed will drop, and the chair will climb more slowly than on flat ground.
Will the chair fit in a car trunk?+
Yes, the folded footprint is about 25.9 x 14.0 x 32.3 in (658 x 355 x 820 mm), which fits most sedans, hatchbacks, and SUVs. Lift the chair by the cross-brace strap and not by the armrests when loading.
Is the chair safe on grass or gravel?+
Yes, the 12 in rear wheels and the 7 in front casters handle short grass paths and packed gravel. Soft sand, deep gravel, and wet grass will reduce the 12.4 mi range and the 3.7 mph top speed, so plan a shorter loop on those surfaces.
Can I take the chair on a plane?+
Yes, the dual 24 V 6 Ah lithium battery packs are sized within the watt-hour limit most airlines accept for carry-on mobility devices. Call the airline in advance for their current label and documentation requirements.
How long does the battery last?+
Each 24 V 6 Ah lithium battery pack is rated for 500+ charge cycles, which is roughly two to three years of daily use. Swap a worn pack for a fresh one rather than opening the battery case, and the controller will pick up the new pack without any setup step.
What warranty comes with the chair?+
The chair ships with a manufacturer warranty covering the frame, the motors, and the electrical components. The exact terms are printed on the warranty card inside the box, and the support team can email a copy of the card on request.

Why Choose the HKM-5337555
Folds for the Car
The cross-brace folds the chair in about three seconds, so the chair fits in most car trunks and rides in the back of a ride-share without a ramp. The folded frame stands upright in a closet so it does not block the hallway.
Approved for Air Travel
Two 24 V 6 Ah lithium battery packs inside the frame are sized for airline carry-on rules that vary by carrier. Call the airline ahead of time for their current documentation and label requirements.
Two Batteries, One Charge
Two removable 24 V 6 Ah packs share the load, so you can swap one pack for a spare at lunchtime, run an inverter off the second pack, or charge each pack on a different outlet while you sleep.
Easy to Drive
The 360 degree joystick moves the chair in the direction you push, and the electromagnetic brake stops the chair the moment you let go. No parking lever is needed on flat ground or on a gentle slope.
Washable Cushion
The breathable mesh seat and backrest unzip for a wash cycle, so crumbs, pollen, and sidewalk dust lift out after a long weekend outdoors. A fresh cushion turns an ordinary chair into a tidy one.
Backed by Local Warranty
The chair ships with a manufacturer warranty and a responsive support team in the United States. Need a spare armrest, a footrest, or a replacement battery pack - the parts stream is the same supply chain that delivered the chair.
Controls & Indicators
Power Button
Press the power button on top of the controller to wake the joystick. Hold the same button for a few seconds to switch the chair off before lifting the user off the seat.
Joystick
Push the joystick in the direction you want to drive. Release it to stop, and the electromagnetic brake will hold the chair in place on any slope the chair can climb.
Speed Selector
Tap the speed button to cycle through five speeds, from a slow indoor pace up to the 3.7 mph top speed. Start low on a new surface and step up once the chair feels settled.
Horn Button
Press the horn button to beep at doorways, narrow aisles, and crowded sidewalks. A short tap is the polite way to ask for space without leaving the joystick.
USB Charging Port
Plug a phone cable into the USB port on the controller to top up a phone while you ride. The port shares power with the controller, so the chair must be on for the port to deliver current.
Battery Indicator
Glance at the LED bars on the controller to read the remaining charge. The bars drop one at a time as the battery nears empty, and the last bar blinks before the chair begins to slow down.
Manual / Electric Switch
Flip the red lever on each motor hub to switch between electric drive and free-wheel mode. Use free-wheel only on flat ground and never on a slope.
Pre-Ride Safety Checklist
- Check the joystick, the power button, and the horn by tapping each one before the user steps aboard.
- Confirm the 24 V battery indicator shows a full charge for the planned trip, and top off the second pack if the first is low.
- Inspect the front 7 inch solid wheels and the 12 inch rear wheels for cracks, missing treads, or pebbles caught in the rim.
- Release the electromagnetic brake by moving the joystick briefly and confirm the chair rolls and stops as expected.
- Lift the armrests, then lower them, until each clicks into place so the user has a firm side to lean on.
- Swing the footrest down and lower it for the user, making sure the heel sits behind the rear edge of the tread.
- Fasten the seat belt across the lap and pull the strap until the buckle holds without pinching.
- Walk a short loop at the slowest speed before heading out, and listen for clicking, rubbing, or motor whine.
Quick Troubleshooting
The chair will not turn on.+
Charge the 24 V battery packs for a full cycle, then press and hold the power button on the controller for a few seconds. Swap the two packs and try again if the first pack reads empty on the indicator.
The joystick feels stiff or sticky.+
Wipe the rubber boot around the joystick with a dry cloth and check that the boot is not pinched against the controller housing. Move the joystick through the full range a few times to work the boot loose.
Range drops below 12.4 mi on a full charge.+
Cold weather, soft tires, and a heavier user will all cut the daily range. Charge the packs at room temperature, switch to a flatter route, and check whether the chair has been overloaded for several trips.
The electromagnetic brake will not release.+
Switch the red clutch on each motor hub to the electric-drive position, then press the power button to wake the controller. The brake will release on the first nudge of the joystick.
A battery pack rattles in the frame.+
Open the lower frame tube, lift the pack, and reseat it until the latch clicks. A loose pack can trigger the low-battery warning on the controller and cut the top speed to protect the cells.
The chair beeps when the joystick is released.+
Release the joystick and let the chair rest for a few seconds. The beep is a self-check sound that clears once the controller confirms the electromagnetic brake is holding the chair on the slope.

Important Safety Notes
Read the user manual before the first ride, and walk a short loop at the slowest speed to get used to the joystick before heading out. The chair is a mobility device, not a medical device, and the manual lists the safety checks the manufacturer expects before each ride.
- Always fasten the seat belt before driving, and keep the belt across the lap rather than the waist.
- Drive at the slowest speed on ramps, in doorways, and on crowded sidewalks.
- Release the joystick to stop, and trust the electromagnetic brake to hold the chair on a slope.
- Switch to manual mode only on flat ground, and never on a slope or a curb.
- Keep fingers clear of the rear wheels while the chair is in electric mode.
- Charge the battery packs indoors and away from flammable materials.
- Do not lift the chair by the armrests, the joystick, or the seat belt - use the cross-brace strap.
- Inspect the wheels, the brakes, and the battery terminals before each ride.
