CHALLENGE The Problem We Set Out to Solve
Portable power banks are convenient, but they're also heavy, expensive, and slow to charge. The bigger and longer-lasting the battery, the heavier the price and weight burden gets. If campgrounds and apartment complexes had stations for swapping standardized batteries, portable fridges and electric wagons could run lighter and cheaper.
🔋 The existing power-bank market — bigger capacity means pricier, heavier products
SOLUTION The Limits of Power Banks Today → The Swappable-Battery Fix
If existing power banks and portable fridges were a hassle because of
- Heavy, expensive built-in batteries — bigger capacity means a bigger price and weight burden
- Long charging times, with no backup if it dies mid-use
- Cold storage at campgrounds relying on coolers and ice
- The hassle of hauling heavy camping gear yourself
With swappable-battery infrastructure
- Battery-swap stations installed at campgrounds and apartment complexes
- A portable fridge that runs on standardized batteries — 24-hour cooling plus power for devices and lighting
- A battery-swap electric wagon that carries heavy loads with ease
- When it dies, swap the battery instantly — no waiting to charge

PLAN Rollout Scenario — From Campgrounds to Apartment Complexes
Like the "ice-cup stand" of a campground, we're extending battery-swap fridges and electric wagons into everyday spaces.
1
At Campgrounds
Battery-swap portable fridges and electric wagons act as a mini mobile convenience store at the campground, cutting the burden of hauling heavy gear and enabling 24-hour cooling.
2
At Apartment Complexes
Use an electric wagon for grocery-store shopping, and keep frozen/refrigerated deliveries fresh in a battery-swap fridge left at the door.
🛒 Grocery store — from shopping to getting home, all on the electric wagon
🚪 Apartment doorway — temporary storage for fresh food, then straight to your next camping trip

🧞The "everyday ice-cup stand" — turning battery-swap stations into everyday infrastructure
Battery-swap stations at campgrounds and apartment complexes become the "everyday ice-cup stand."
