The Problem
Three objects
to charge
one phone.
- 01A caseProtection only. No power.
- 02A power bankExtra weight you forget to charge.
- 03A brick + cableTwo more things in every bag.
The case protects the phone, carries 4,000 mAh of power and plugs straight into the wall. Nothing else to pack.
One object
Case. Battery. Plug.
The Technology
Power that travels inside the phone.
SQUIRL turns the phone case itself into a complete charging system: an integrated 4,000 mAh battery plus fold-out wall-charging plugs, protected by multiple utility and design patents.
- 01Recessed prong bayStainless-steel AC prongs sit inside the shell, flush with the surface, until released.
- 02Integrated 4,000 mAhCharge the case on its own, or keep the iPhone inside and charge both from the wall.
- 03Machined internal frameSoft-touch composite over a rigid core — presence in the hand without bulk.
- 04USB-C pass-throughData, audio and charge behave exactly as they do without the case.

Step 1 · SlideIn the wild
Wherever there's an outlet,
there's a charger.
Home, work, the coffee shop, the hotel, the airport. One case goes with the phone and turns any standard outlet into a full charge.
Charge at the desk without owning the desk.
The hotel and nightstand brick, retired.
Every outlet on earth is now your charger.
Industrial Design
Engineered to
disappear.
Every millimetre of the mechanism is hidden inside a shell you'd carry anyway. Premium cord-free charging for modern mobile life — one object that protects the phone, carries the power and plugs into the wall.
Built-in wall plug
Stainless-steel prongs fold out of the shell and back flat in one motion.

A second full charge carried inside the case, not in your bag.

Travel-ready
Home, office, coffee shop, hotel, airport — no brick, no cable.

“Finally, no cable needed.”
“Charges my phone anywhere there's an outlet.”
“Feels like a premium case, works like a charger.”
Originally introduced for earlier iPhone generations and sold through major big-box retailers, SQUIRL earned Amazon's Choice, Top Rated Seller and Free Shipping placements. Demand for cord-free charging is established, not theoretical — and the new generation is built for iPhone 17, with an iPhone 18 version to follow.
Protected Innovation
The plug is the patent.
Competitors add capacity. SQUIRL removes the charging brick entirely — and the mechanism that makes it possible is protected by multiple utility and design patents.
Utility & design patents
Multiple granted patents covering the integrated fold-out wall-charging plug within a battery case body.
Mechanical architecture
A recessed slide-and-hide hinge that survives repeated cycles and sits flush when stowed.
Platform expandability
The mechanism scales across device generations, regions and adjacent product categories.
Retail · Licensing · Acquisition
Your brand. Our IP.
Previously sold through major big-box retailers and now returning with a new generation for iPhone 17, SQUIRL is positioned for retail distribution, brand licensing and strategic acquisition — with patented IP and proven sell-through behind it.
- 01Differentiate a crowded accessory shelf with a category-defining SKU
- 02Reduce reliance on bundled chargers as regulation tightens
- 03License protected IP instead of engineering around it
- 04Meet USB-C and sustainability commitments with one product
A product people actually use daily.
