Powerfull

is a powerbank rental product launched in public venues across the UAE and Europe. There was no existing product — only a basic idea and raw sketches. I led the entire design effort: from research and product modeling to brand and UI system.

Outcomes

After launching in the UAE, the product was reused with minimal visual changes by partners in other markets.

Problem

The initial prototype included only a few disconnected screens with no logic or real flow. Through analysis, I identified core UX gaps:

Lack of clarity about powerbank availability and station status

No guidance inside venues (where to find the station)

Confusing or overloaded flows in similar rental apps

No persistent visibility of rental status or cost

Goal

Create a fast, clear, and context-aware rental experience that works reliably in real-world use.

Research

To define a better model, I:

Conducted a user survey with
24 participants to validate assumptions and test early flows

Analyzed 35+ apps (powerbanks, scooters, bikes) for flow patterns and UX pitfalls

Extracted best practices for onboarding, location discovery, and active rental

Solution

The product was built around a clear, low-friction user experience optimized for real-world conditions.

Smart station view with photo, walking distance, and description of indoor location

Live rental status showing time, cost, and auto-purchase threshold

Fast start — immediate access to station map on first open

Return flow with clear CTA and fallback messaging

Outcomes

After launching in the UAE, the product was reused with minimal visual changes by partners in other markets.
