Product details
Detachable Built-in USB-C to C Cable
A mobile battery equipped with a built-in USB-C cable.
Even if the cable is damaged, it can be replaced thanks to the detachable design, ensuring long-term and reliable use.
The approximately 21 cm built-in cable wraps neatly around the body, enabling fast charging for both your smartphone and the battery itself with a single cable.
※ The built-in cable is exclusively designed for SMARTCOBY Pro SLIM CABLE and is not compatible with other CIO products.
※ When inserting the built-in cable, please ensure the connector is fully and straightly inserted.
※ This product is a wired charging model and does not support Qi or MagSafe wireless charging.
Ultra-Slim & Lightweight Design
Measuring only 18 mm thick, this palm-sized slim power bank pairs perfectly with popular smartphones such as the iPhone 15.
Weighing only about 189 g (including the cable), it’s extremely portable for travel, office, business trips, or daily use at home.
Recommended for everyone—from students to professionals—who needs a compact, easy-to-carry power solution.
Single-Port 35W Max Output & Large Capacity
Equipped with a 10,000 mAh capacity and supports up to 35W output via a single USB-C port.
The 35W output drastically improves convenience, allowing charging not only for smartphones that require 20W output (iPhone, Galaxy, Xperia, and other Android devices) but also tablets (iPad / iPad mini / iPad Pro) and even mid-range laptops such as MacBook Air.
Fast Charging Support
The SMARTCOBY Pro SLIM CABLE supports PPS (Programmable Power Supply), allowing Super Fast Charging mode for Galaxy devices.
The main battery itself also supports 35W input, enabling full recharge in about 90 minutes when using a compatible fast charger.
Digital Power Display
When not in use, the surface remains flat and clean, blending the display with the body for a sleek look.
Unlike conventional glossy displays that easily show scratches, this model features a matte-textured surface identical to the main body, making scratches less noticeable.
During charging, the remaining power is displayed numerically, and while recharging the battery itself, an animated graphic playfully indicates progress.
Pass-Through Charging Support
Enables simultaneous charging of both your device and the power bank.
Even when the power bank is empty, you can plug it into the wall outlet and charge your smartphone or other devices through the battery.
Ideal for environments with only one outlet or when you want to charge both the battery and your device at once.
The built-in pass-through feature allows convenient charging in any situation.
Dual-Port Configuration
Designed with two USB-C ports, including the built-in cable, to maximize the functionality of the flat form factor.
This enables flexible charging options—charge an iPhone or Android via USB-C while charging another USB-C device or an accessory such as earphones.
It also supports pass-through charging that adapts to your device and cable setup.
Functional and Durable Exterior
To ensure long-term use, the surface features a fine matte texture inspired by DSLR camera bodies.
This design makes it resistant to scratches and scuffs, even from pens or fingernails, adding both functionality and durability for extended everyday use.
