PocketSolar: Foldable Solar Phone Charger
Summary
My company, PocketSolar, is developing a wallet-sized foldable solar charger to help travelers, hikers, and outdoor enthusiasts stay connected and powered up with reliable emergency charging that works anywhere there's sunlight.
Problem statement
Customers struggle with their phones running out of battery when they're away from traditional power sources, which leaves them disconnected, unable to navigate, or stranded in emergency situations.
Solution
PocketSolar is a compact, tri-fold solar charger that fits in your wallet when closed but expands to three high-efficiency solar panels when opened. The device connects directly to your phone via USB and harnesses sunlight to deliver a full charge in approximately two hours, eliminating the need for wall outlets or power banks during outdoor activities or emergencies.
Growth metric
The key metric to focus on is monthly active users (MAU) who successfully charge their devices using PocketSolar. To scale this metric to affect 1 million people, the company should establish partnerships with outdoor gear retailers like REI, Patagonia, and camping supply stores to reach adventure enthusiasts, and develop a direct-to-consumer subscription model offering seasonal solar accessories and replacement parts to build recurring engagement.
