Product details

Introducing the SMARTCOBY ULTRA SLIM 3K — a fusion of elegance and performance.

Crafted with cutting-edge technology, this ultra-slim power bank combines sleek design with powerful charging, giving you the freedom to carry it anywhere without compromise.

For your daily commute, weekend getaways, and everything in between.

The SMARTCOBY ULTRA SLIM 3K blends seamlessly into any lifestyle.

With an ultra-thin 4.98 mm (0.196inches) design, it slips easily into your wallet or planner.

Stack it with your phone, and you’ll hardly notice it’s there—until the moment you need reliable power right at your fingertips.

So slim, it feels invisible.

So powerful, it’s always ready when you are.

This is the new meaning of portable peace of mind—right in the palm of your hand.

The Revolution of Slim.

Just 4.98 mm (0.196inches)thin and weighing only 82 g.

Thinner than a smartphone, so light you’ll forget it’s even there.

It’s “here,” yet it feels like “nothing.”

A whole new experience in portable power.

Every 0.1mm Counts.

A stainless-steel frame, Tier-1 battery cells, and a liquid silicone adhesion surface—

each material refined to its thinnest form, working together to create an ultra-slim body.

(This illustration highlights the core materials. The final product also includes magnets, circuit boards, and other components, resulting in a total thickness of 4.98 mm.)

Three Pillars of Safety

Crafted with an ultra-slim design that never compromises on protection:

Reinforced Stainless Steel Frame – unmatched strength and rigidity.
Premium Tier-1 Battery Cell – trusted for stability with minimal risk of swelling.
Liquid Silicone Contact Surface – protects your smartphone from scratches while providing secure adhesion.

It’s not "thin but fragile."

It’s designed to be both thin and secure, emphasizing safety and reliability in daily use.

Stainless Steel Exterior with Premium Craftsmanship

Unlike ordinary power banks with plastic bodies, the SMARTCOBY ULTRA SLIM 3K features a stainless steel exterior—renowned for its exceptional strength and rigidity.

Through a meticulous process of press molding, mirror polishing, laser cutting, PVD coating, and anti-fingerprint treatment, we’ve created a body that delivers both durability and a premium finish.

To ensure true safety, a battery must be designed with the risk of internal swelling in mind.

The SMARTCOBY ULTRA SLIM 3K uses high-quality battery cells from Tier-1 battery cells manufacturer, a global supplier known for providing components to leading technology brands, including Apple.

Based on internal testing under controlled conditions, Tier-1 battery cells demonstrated a swelling coefficient of approximately 1.04%. Actual performance may vary slightly in mass production.

That’s why we were able to achieve this ultra-thin 4.98mm body.

In fact, its slimness is not just about design — it’s proof of its outstanding safety.

A Surface Built for Everyday Contact

Because it’s a surface that attaches to your smartphone again and again, it had to be thin, soft, and strong.

The adhesive layer is engineered with polycarbonate reinforced by an overmold of liquid silicone — combining scratch-resistant softness with outstanding durability in just a fraction of a millimeter.

This invisible layer of thoughtful design ensures your phone stays safe, while keeping the device ultra-slim and comfortable to use every day.

MagSafe® compatible — designed for magnetic alignment with iPhone 12 and later models (not an Apple-certified accessory).

Supports up to 10W fast charging under optimal conditions.

When plugged in, the unit automatically switches from wireless to wired charging.

Just-Right Capacity for Everyday Carry

Get the power you actually need—without the bulk.

The 3000mAh SMARTCOBY ULTRA SLIM 3K delivers about a 40–60% top-up for iPhone 15/16.

Slim, light, and easy to carry, it’s made for people who prefer a smarter, lighter setup over oversized batteries.

Built-in Find My® feature

works seamlessly with Apple’s Find My network. You can locate it from your iPhone, receive alerts, and play a sound to find it.

Because this mobile battery is designed to stay with you in your wallet or bag every day, we’ve integrated Find My so you’ll never lose it.

* Image shown is for illustrative purposes. This product contains built-in magnets. Do not place or store credit cards, IC cards, or similar items near the device as magnetic data or chips may be damaged.

* Find My operates for about two months on a dedicated power source separate from the battery itself. Initial pairing setup is required to use the Find My feature.

* Find My is an Apple-certified feature.

Minimal by design, yet thoughtful in every detail.

A single press of the power button reveals the remaining charge through a soft glow of three LED colors.

No clutter, no distractions—just the quiet reassurance of knowing exactly how much power you have left.

By keeping it to one discreet light, it preserves both simplicity and elegance, making every glance effortless.

Charge both your phone and the battery at once.

With SMARTCOBY ULTRA SLIM 3K, simply connect a USB-C cable and enjoy seamless pass-through charging — your smartphone and the power bank charging together, with your phone always prioritized.

Imagine this: plug it in before bed, attach your phone, and by morning both are fully charged and ready to go. Slip them into your bag still connected, and your day begins without a second thought.

It’s a small feature, but one that transforms everyday convenience into peace of mind.

Every great product begins with a simple idea on paper.

Before achieving its final ultra-slim form — only 4.98mm thin — the SMARTCOBY ULTRA SLIM 3K went through multiple stages of design, testing, and refinement.

We started from hand-drawn concept sketches to explore the ideal balance between compactness, durability, and charging efficiency.

The drawing below represents the earliest design concept — visualizing the foundation for what would become our functional prototype.

From paper to reality — our vision took shape through continuous testing and iteration.

We refined each component, ensuring that the stainless-steel frame, Tier-1 battery cell, and liquid silicone coating maintained both strength and elegance.

After months of prototyping, the result is a sleek, functional model that perfectly aligns with our design vision.

Precision Craftsmanship in Every Layer

Every component of the SMARTCOBY ULTRA SLIM 3K was designed to achieve extreme thinness without compromising strength or safety.

The production process involves multiple precision steps — from laser-cutting stainless steel to integrating Tier-1 manufactured battery cells, all the way to final assembly and coating with liquid silicone for a smooth touch.

The diagram below shows the internal composition and layer structure.

Each layer contributes to durability, thermal stability, and the signature slim profile of just 4.98mm.

After assembly, every unit undergoes testing for:

Charging efficiency
Heat management
Durability and flexibility of materials

Only after passing these tests, the product moves to the next stage — final finishing and packaging.

Accessories that comply with Apple’s official accessory design guidelines will not interfere with the camera and can be used seamlessly with magnetic attachment.

It’s not just about avoiding camera interference.

We designed “SMARTCOBY ULTRA SLIM 3K” to preserve the natural feel of your iPhone in your hand.

That’s why we focused not only on thinness, but also on compact width.

At just 70mm wide, it fits seamlessly with every iPhone from iPhone 12 onward—keeping the grip as clean and comfortable as Apple intended.

“So glad I had it.” — moments you’ll experience again and again.

Slip it out in an instant, charge smoothly anywhere.

Thin. Light. Effortless.

A quiet companion to your everyday life—

before you know it, you can’t imagine being without it.
