Robooter E40
The tightest turning chair Robooter make, and the one in the range built to live indoors.
The number that decides who lifts it
About 55 lb, and the battery comes out first.
Robooter publish this chair at 25 kg, about 55 lb, as its product net weight. The battery lifts out before you pick anything up, so the piece you actually handle is lighter again. It folds into one piece, which makes the folded frame the single heaviest thing you ever carry.
- ✓About 55 lb ready to driveProduct net weight
- ✓7.5 lb battery, and it lifts outTake it out and every lift gets smaller
- ✓A comfortable two person lift into a trunkOne person with a short ramp
Getting it into the car
It folds by hand into one piece, and stands 17.7 in tall.
Folded, the E40 is 27.6 in long, 24.6 in wide and 17.7 in tall, which is 700 by 624 by 450 mm on Robooter's own table. It folds by hand, so there is no folding motor to keep charged, and nothing comes apart, so there is nothing to leave behind in the garage.
- ✓17.7 in tall foldedThe measurement that decides whether it clears the lip of your trunk
- ✓27.6 in long and 24.6 in wide foldedLay it flat in the trunk, or stand it up behind a seat
- ✓Folds by handNo tools, no catches to learn, and the same fold every time
- ✓The 7.5 lb battery lifts outCarry it indoors to charge, and the frame goes into the car that much lighter

Folded, and still one piece. Hold the 17.7 in height against your trunk opening and you will know in one look.
The seat, the doors and the turn
17.3 in of seat, 24.6 in across, and it turns inside 17.7 in.
Seat width decides whether an hour in the chair is comfortable, so it leads here. Robooter's metric table gives the seat at 440 mm wide and 440 mm deep, which is 17.3 in each way, and they list the cushion as the same 440 mm square. The chair itself measures 624 mm across at its widest, or 24.6 in, and that is the number your doorways care about.
A standard interior door
Fits, 7.4 in to spareA 32 in door, against a 24.6 in chair
✓Straight through, no angling and no shuffling
✓Room either side for your hands on the armrests
An older, narrower door
Fits, 3.4 in to spareA 28 in door, against a 24.6 in chair
✓Still a comfortable gap at normal walking pace
✓No need to line the chair up perfectly
A narrow bathroom door
Too close to callA 24.5 in door, against a 24.6 in chair
≈The two measurements sit a tenth of an inch apart
≈Openings this narrow vary with the frame in them, so we call it neither way
iWhere the E40 earns its keep. It comes about inside 17.7 in. The E60 needs 31.5 in and the X40 needs 29.9 in, so in a hallway, a small kitchen or a bathroom doorway this is the difference between backing up twice and simply turning.
How far one charge goes
Twenty three kilometres, and what quietly shortens it.
Robooter publish 23 km from the 20 Ah lithium pack this chair ships with. Read it as the best a fresh battery will do on a flat, dry, mild day, and treat it as the ceiling rather than the plan. Four things move the number, and only one of them is the battery.
- ✓ColdEvery battery gives up some of its capacity in the cold, and a Canadian winter is where you feel it
- ✓Slopes and thick carpetA ramp, a driveway or deep pile all pull harder on the battery than a flat floor
- ✓Your weight, and what you carryThe closer to the 330 lb rating, the harder the motors work for the same distance
- ✓Stopping and startingA steady roll asks less of a battery than a route full of pulling away again
iThe battery, and where it charges. The 20 Ah pack is the one that carries the 23 km figure. It weighs 7.5 lb and lifts out, so it can charge indoors on a counter while the chair waits by the door. Robooter also list a smaller 12 Ah pack for this chair, sold separately.
