SMARTCOBY SLIM 5K (Safe model)

Heat-Reduction Priority Model 

This product was developed in response to customer feedback requesting “a model that minimizes heat generation.”
The SMARTCOBY SLIM 5K Safety Model prioritizes temperature stability during operation.
For users seeking fast charging performance under the Qi2 standard (maximum 15W output), we recommend the SMARTCOBY SLIM 5K High-Performance Model.

 ※ The Safety Model shares the same hardware specifications as the High-Performance Model (Qi2 max 15W output, dimensions, weight, etc.).
Only the firmware program that controls power output and heat generation has been adjusted. 

Equipped with a Qi2 Certified Chip 

The SMARTCOBY SLIM 5K supports magnetic wireless charging for iPhone 12 / 13 / 14 / 15 / 16 / 17 series, iPhone Air series, and Pixel 10 series.
It provides stable, contactless wireless charging while minimizing heat buildup.
The iPhone 16 Pro can be fully charged in approximately 170 minutes (the High-Performance Model takes about 150 minutes).
Because it complies with MagSafe technology, it can be used safely even after future iOS updates. 

Maximum 20W Single-Port Output 

The USB-C port supports a maximum output of 20W, allowing wired charging for smartphones (iPhone, Galaxy, Xperia, and other Android devices) as well as tablets (iPad / iPad mini / iPad Pro, etc.). 

Ultra-Thin 8.7 mm Design 

Combining ultra-thin and compact construction, this product achieves minimal size, thickness, and weight.
Even when stacked with a smartphone such as an iPhone or Galaxy, it fits comfortably in your hand without protruding beyond the device’s edges.
It can also be easily stored in a small pocket of a bag or pouch.
Perfect for cafés, trains, airplanes, business trips, and travel.
※ When used with iPhone mini models, the battery will slightly extend beyond the phone’s edges. 

Simple and Elegant Aluminum Alloy Body 

Constructed with ultra-thin battery cells, this sleek metallic design complies with Apple’s accessory design guidelines.
It does not interfere with the camera when magnetically attached to an iPhone, and remains comfortable to use even with a protective case installed. 

Complete Pass-Through Charging Function 

While charging the power bank itself, it can simultaneously charge your smartphone or other device.
The SMARTCOBY SLIM 5K uses CIO’s proprietary complete pass-through circuit, which automatically switches to direct device charging once the power bank is fully charged.
This design reduces internal battery cell stress, extending lifespan and improving safety.
※ When using complete pass-through charging, wireless output is limited to 5W. 

Battery Capacity and Energy Loss 

※ The rated capacity of this product is 5000mAh (3.85V, 19.25Wh).
However, because energy loss occurs when transferring power to another device, the actual usable capacity is approximately 3000mAh (5V/2A), about 60% of the rated value.
In wireless charging, additional energy loss occurs during electromagnetic induction, so the effective charge capacity will be reduced.
When using fast charging (e.g., PD 9V), the effective discharge capacity may decrease due to conversion efficiency.
Although the battery’s total energy is 19.25Wh, the actual usable capacity when discharging at 9V is approximately 2139mAh. 

CIO Reliable Warranty 

As a Japanese manufacturer, CIO provides full support for defective units.
If you experience any issues during use, please contact us directly.
Providing your order number or the name of the retailer will help us assist you more efficiently.
※ Products may have signs of unsealing due to inspection prior to shipment. Please be assured that all units are brand-new and unused. 

Wireless Charging Compatibility and Heat Considerations 

※ Magnetic wireless charging up to 15W is available only on iPhone 12 and later models running iOS 17.4 or later.
※ For iPhone 11 or earlier, and iPhone SE or 16e models, the maximum wireless output is 7.5W.
※ For Android smartphones, the maximum wireless output varies by device model.
Please check your device’s Qi2 charging specifications.  
※ The maximum 15W performance may vary depending on battery level and ambient temperature. 

When watching videos, gaming, or using your phone during charging, or in environments above 25°C (77°F), charging speed may decrease significantly.
To achieve optimal performance, charge in a cool environment and avoid using your device simultaneously.
