Overview
The HKM-7827923 is a folding electric wheelchair built around a 24 V 12 Ah removable lithium-ion pack and a pair of 250 W brushless hub motors, which together deliver the 500 W of tractive effort advertised on the title. The aluminum-alloy frame folds in roughly five seconds and ends up small enough to roll behind a car seat or into a taxi trunk. A right-hand joystick, an electromagnetic brake, and pneumatic rear tires round out the drive system.
The silver aluminum-alloy frame is welded rather than bolted, with a hinged backrest and a single cross-brace release that locks the chair open for use. When the lever is pulled, the chair collapses inward to 24.4 x 13.8 x 34.4 in (620 x 350 x 875 mm) and weighs roughly 64 lb without the battery and joystick. A red gas strut on the cross-brace cushions small bumps and softens the drop into the seat.
Two 250 W brushless DC hub motors live inside the 12 in rear wheels, which use pneumatic tires with visible tread for grip on sidewalks and ramps. The motors pull the chair up to 3.7 mph (6 km/h) and climb slopes up to 8 deg, while the electromagnetic brake stops the chair the moment the joystick is released. Two 6 Ah lithium cells wired in parallel deliver the full 12 Ah capacity that powers a 12.4 mi (20 km) range per charge.
The 24 V / 2 A joystick controller mounts on either armrest without tools and carries a power button, a horn, a speed dial, and a battery indicator on the same housing. Padded foam armrests flip upward for side transfers, the footrest flips up out of the way, and the cushioned seat measures 17.3 in wide by 17.7 in deep. Anti-tip wheels at the rear of the frame keep the chair stable on ramps, and a charging port on the battery pack accepts a 100-240 V input from the supplied charger.
Key Features
Dual 250 W Brushless Hub Motors
Two 250 W brushless DC hub motors drive the rear wheels for a combined 500 W of tractive effort, which is enough for everyday sidewalks and gentle ramps up to 8 deg. The motors are sealed against splashes and run quietly, so the chair can be used indoors without disturbing conversation or office settings.
Folds in About Five Seconds
Pull the cross-brace release and the chair collapses inward in roughly five seconds, ending up at 24.4 x 13.8 x 34.4 in (620 x 350 x 875 mm). That footprint fits the trunk of most sedans and hatchbacks without removing wheels or breaking the chair down further.
Removable 24 V 12 Ah Lithium Battery
The 24 V 12 Ah lithium-ion pack slides out from the side of the frame so it can be charged off-board in a hotel room or home office. Two 6 Ah cells are wired in parallel internally to deliver the full 12 Ah capacity that powers the 12.4 mi (20 km) range.
Intelligent Electromagnetic Brakes
An intelligent electromagnetic brake engages the moment the joystick returns to center or the power switch is flipped off, holding the chair on the slope without any action from the user. The brake release lever on the motor lets a companion push the chair in manual mode if needed.
Left or Right Joystick Mount
The controller bracket fits either armrest, so the joystick can be swapped to the left or right side without tools to match the user's dominant hand. The 24 V / 2 A controller also carries a horn button, a power button, and a battery indicator on the same housing.
Anti-Shake Cross-Brace Suspension
A red gas strut mounted to the lower cross-brace cushions small bumps and softens the seat when the user sits down, which is a noticeable comfort improvement over chairs that fold flat without any spring assist. The strut is rated for the chair's 265 lb (120 kg) load capacity.
Pneumatic 12 in Rear Tires
The rear 12 in wheels use pneumatic tires with visible tread for grip on sidewalks, ramps and light gravel, while the front 7 in solid PU casters keep steering light and maintenance-free. Anti-tip wheels at the back of the frame prevent the chair from pitching backward on a slope.
Airline-Friendly Lithium Chemistry
The lithium-ion pack meets typical airline and cruise-line limits for spare mobility batteries when it is carried in the cabin as a carry-on. Always confirm with the carrier before flying because each airline enforces its own watt-hour threshold and packaging rules.

Battery, Range, and Charging
HKM-7827923 ships with a 24 V 12 Ah removable lithium-ion battery that delivers the 12.4 mi (20 km) per-charge range advertised on the title. The pack is built from two 6 Ah cells wired in parallel inside a single housing, so the rider never has to manage the cells separately. Under typical conditions with a 165 lb rider on level sidewalk, the chair returns roughly that range; cold weather, hills, and a heavier rider all shorten it.
Charging the pack from empty takes about 6 to 8 hours with the supplied off-board charger, which accepts a 100-240 V input at 50/60 Hz so it works on most international outlets with the appropriate plug adapter. The charger shuts off automatically when the pack is full, so the chair can be left plugged in overnight without damaging the cells. A full charge adds roughly 5 lb to the chair because the pack itself weighs about that much and clicks into the side of the frame.
Tip: Store the battery indoors at room temperature when the chair is parked for more than a week. Avoid storing the pack at 100 percent charge or fully drained, because both extremes shorten cell life; roughly 50 percent state of charge is the recommended storage target.
Because the battery is removable, the rider can leave the chair folded in the trunk and bring the pack inside to charge, which is convenient in apartments, hotels, and offices where the chair itself cannot reach an outlet. The pack also matches typical airline carry-on rules for spare lithium-ion mobility batteries, although each airline enforces its own watt-hour threshold.
Daily Use & Care
- Charge the battery after every outing, even short ones. Lithium-ion packs last longer when they are kept between 20 and 80 percent state of charge rather than being drained to zero.
- Inflate the rear pneumatic tires to the pressure printed on the sidewall every two weeks. Soft tires shorten range, slow acceleration, and make the ride feel sluggish on flat ground.
- Lock the cross-brace before sitting down. The folding release lever must click into its open position or the chair can fold under load and tip the rider forward.
- Switch the joystick to the left armrest if a stroke, injury, or surgery has left the right hand weaker. The controller is reversible and the brake works the same on both sides.
- Wipe the frame with a dry cloth after outdoor use. Moisture, salt, and grit speed up wear on the joystick cable, the brake release lever, and the folding hinge.
- Store the chair indoors when it is not in use. Direct sunlight fades the seat fabric and dries out the foam padding, while overnight dew can corrode the steel hardware.
- Drive in the lowest speed setting for the first week. The joystick is more responsive than a manual chair's push rims, and an unexpected burst of speed at a curb cut is the most common first-day surprise.

Why Choose the HKM-7827923
Folds Small Enough for a Car Trunk
The collapsed footprint of 24.4 x 13.8 x 34.4 in fits behind most rear seats, so daily errands do not require a wheelchair lift or a van.
Easy for Solo Travelers
With a removable battery and a one-step fold, the chair can be packed into a taxi, rideshare, or rental car without waiting for a companion to help.
Switchable Left or Right Joystick
The joystick can be moved to either armrest in seconds, which is useful for users who have full use of only one hand after a stroke or injury.
Light Enough to Lift
At approximately 64 lb without the battery and joystick, the chair can be lifted into a trunk by a single adult who is comfortable with that weight.
Comfortable for Long Outings
A padded seat, a cushioned backrest, and the anti-shake gas strut all work together to reduce vibration during half-day trips to parks, museums, or shopping centers.
Built for Everyday Sidewalks
Pneumatic rear tires, electromagnetic brakes, and an 8 deg climbing rating cover the slopes, ramps, and curb cuts found on typical community routes.
Controls & Indicators
Joystick Controller
The joystick sets direction and speed. Push forward to drive forward, pull back to reverse, and let go to stop. Speed is adjusted with the dial on the controller housing.
Power Button
Press the power button on the controller to wake the system. The battery indicator lights up and the joystick becomes active within a second or two.
Horn Button
Tap the horn button to alert pedestrians and other riders. The horn uses a short electronic chime, not a continuous tone.
Speed Selector Dial
Turn the dial between the turtle and the hare to pick a top speed. New users typically start at the lowest setting until they are comfortable with the joystick response.
Brake Release Lever
Pull the red lever on each motor hub to release the electromagnetic brake so a companion can push the chair in manual mode. Push the lever back before driving under power.
Charge Port
The charge port sits on the side of the battery pack. Plug the supplied charger into the port, then into a 100-240 V wall outlet. The charger light turns green when the pack is full.
Folding Release Lever
Pull the folding release lever on the lower cross-brace to collapse the chair for transport. Lift the same lever to lock the brace open before sitting down.
Pre-Ride Safety Checklist
- Confirm the battery is locked in its cradle and the indicator light on the controller shows a green or full state of charge before driving.
- Check that the cross-brace release lever is in the locked-open position and that both armrests click into place when lowered.
- Inspect both rear tires for correct pressure and look for cuts or debris lodged in the tread before each ride.
- Spin the front caster wheels and clear any hair, string, or gravel wrapped around the axles.
- Power on the controller, wait for the joystick to calibrate, and move the joystick through full travel to confirm smooth response.
- Test the electromagnetic brake by releasing the joystick on a flat surface. The chair should stop within a few inches and stay put.
- Confirm the footrest is locked in the down position and that the rider's feet sit fully on the footplate before driving.
- Switch the chair off and engage the brake release levers if a companion will be pushing the chair in manual mode.
Quick Troubleshooting
Chair will not power on+
Check that the battery is fully seated in its cradle and that the power button on the controller has been held for two seconds. If the indicator light stays off, plug the charger into the pack and try again after the charger light turns green.
Range is shorter than expected+
Cold weather, low tire pressure, and frequent stops on hills all reduce range. Inflate the rear tires to the printed sidewall pressure, keep the battery above 20 percent state of charge, and warm the pack indoors before driving in winter.
Joystick feels laggy or unresponsive+
Switch the chair off, wait five seconds, and switch it back on so the controller reboots. If the lag persists, check the cable under the armrest for kinks or pinching at the folding joint.
Charger light does not turn on+
Confirm that the wall outlet is live, that the charger's barrel plug is fully inserted into the battery port, and that the battery is locked into the frame. Replace the charger only with a unit of the same voltage and current rating.
Electromagnetic brake will not release+
Push the red brake release lever on each motor hub toward the wheel and try again. If the brake still holds, switch the chair off, wait ten seconds, and switch it back on so the brake controller resets.
Chair pulls to one side while driving+
Check both rear tires for equal pressure and inspect the front casters for hair or string wrapped around the axles. Re-calibrate by switching the chair off, centering the joystick, and switching power back on.

Important Safety Notes
The HKM-7827923 is designed for use on sidewalks, indoor floors, ramps, and similar surfaces that a manual wheelchair can already handle. Riders should always observe local traffic rules, wear the included seat belt when one is fitted, and avoid slopes steeper than the rated 8 deg climbing angle, because stability drops quickly beyond that grade.
- Always lock the cross-brace before sitting down.
- Inspect tires, joystick cable, and brake release levers before each ride.
- Do not exceed the 265 lb (120 kg) load capacity.
- Avoid slopes steeper than the rated 8 deg climbing angle.
- Charge only with the supplied 24 V charger.
- Do not expose the battery to water, fire, or temperatures above 113 deg F.
- Switch the chair off before switching between manual and electric modes.
- Consult a qualified clinician about seating and mobility needs.
