FREQUENTLY ASKED QUESTIONS

Who is the Assist Lite designed for?

The Assist Lite is built for emergency mobility scenarios, especially for children, elderly individuals, or persons needing assistance in outdoor or evacuation settings. It’s compact and lightweight ideal for caregivers, schools, public institutions, and families.

What’s included in the box?

Each purchase includes:

  • 1x Assist Lite unit
  • 1x Quick-Release Lithium Battery (36V / 5Ah)
  • 1x Charger
  • 1x Removable Seat Cushion
  • 1x Emergency Manual Handle
  • 1x User Manual

How do I know when to charge the battery?

There’s a built-in battery indicator on the control panel so you can monitor usage and avoid running low during operation.

Does it need a special operator or license?

No. The controls are simple, color-coded push buttons — making it intuitive to operate by trained caregivers, family members, or emergency responders. However, a brief orientation or manual review is recommended before use.

How steep of a staircase can it climb?

It can safely climb stairs with an angle of up to 35°, which covers most standard residential and commercial staircases.

How long does the battery last on a single charge?

On a full charge, the battery lasts for approximately 0.5 hours or up to 40 floors of stair climbing. The 36V / 5Ah lithium battery can be fully recharged in 2.5 hours.

How much weight can it safely carry?

The Assist Lite supports up to 120 kg (264.5 lbs) of body weight. Always ensure the passenger is securely fastened with the four-point seatbelt.

Can it be used without power?

Yes. Assist Lite is equipped with a manual emergency handle, allowing operation even when power is unavailable.

Is it noisy when climbing?

Nope. The motor operates below 70 decibels, which is about as loud as a quiet office. Perfect for schools, clinics, and quiet residential settings.

What are the dimensions of the Assist Lite?

  • Unfolded: 57”L × 19.7”W × 46.5”H
  • Folded: 39.4”L × 19.7”W × 11.8”H
  • Seat Height (from ground): 18.8”
  • Track Length: 29.1”
  • Weight: 39.7 lbs

What is the size of the Assist Lite?

The Assist Lite is compact and portable perfect for emergency or home use:

  • Unfolded Size: 1450 × 500 × 1180 mm (57 × 19.7 × 46.5 inches)
  • Folded Size: 1000 × 500 × 300 mm (39.4 × 19.7 × 11.8 inches)
  • Packaging Size: 1050 × 560 × 330 mm (41.3 × 22 × 13 inches)

It’s easy to store, transport, or fit in tight spaces like stairwells, hallways, or vehicle trunks.

What types of stairs can it handle?

Straight stairs made of concrete, tile, wood, or carpet (with moderate thickness). Not compatible with spiral, curved, or very narrow stairs.

How hard is it to learn?

Not hard at all. Both units have simple fixed-speed controls. Most caregivers master it in under 30 minutes. We also provide a step-by-step manual.

Can I use this alone as a caregiver?

Absolutely. With a little practice, most users (including older or smaller-frame caregivers) can operate either model safely solo. We recommend doing a few practice runs first, without a person in the chair.
