DOKIY C04: The Palm-Sized 10000mAh EDC Power Bank

Why carry a brick when you can carry a card? We believe powerful energy shouldn't weigh you down. The DOKIY C04 is engineered to defy expectations. 

By utilizing an advanced Dual-Cell Architecture, we've compressed 10,000mAh of capacity into a form factor smaller than a credit card. But it’s not just small—it’s tough. 

With a working range of -20°C to 60°C, C04 is ready for freezing ski trips, scorching summer hikes, or your daily commute. One port, total power. Simple, robust, and always ready.

Dual 5000mAh cells in parallel deliver longer-lasting power for your devices.

Lightweight cell layout increases energy density by 30%.

Can charge iPhone, Galaxy, GoPro, cameras, and more multiple times.

SW6224 smart chip automatically balances current between the two cells, ensuring smoother discharge, reducing temperature rise under high loads, extending overall cycle life, and maintaining consistent battery capacity.

Smaller than the width of a credit card, it slips easily into your pocket.

Precision internal stacked structure with a shock-resistant, crush-resistant design (178g).

Supports 22.5W output / 18W input, fully protocol-compatible, with bidirectional fast charging.

Charge your phone, fan, earbuds, and watch all with one device.

Output modes: 5V/3A, 9V/2.22A, 10V/2.25A, 12V/1.67A

Charges an iPhone to 50% in 30 minutes, compatible with PD3.0, QC3.0, SCP, and other protocols.

USB-C bidirectional fast-charging port

Fully charges itself in about 1.5 hours

Supports PD/QC protocol chargers

One Type-C cable does it all

No need to distinguish between input and output ports

Cleaner cable management for a minimalist travel experience

Built to Hang, Born to Style. The DOKIY C04 breaks the mold of boring black bricks. Inspired by tactical gear and cyber-industrial aesthetics, it features a rugged "Desert Tan" finish with anti-slip grooved textures and bold typography. 

The game-changer? An integrated metal carabiner structure. Clip it to your belt loop, backpack, or tactical vest for instant access. It’s not just a power bank; it’s a functional fashion statement that fits perfectly with your Gorpcore or Techwear outfit.

Our power system is built with comprehensive multi-layer safety protection, including Over-Voltage Protection (OVP), Over-Current Protection (OCP), Short-Circuit Protection (SCP), and Over-Temperature Protection (OTP). 

These intelligent safeguards work together in real time to prevent abnormal voltage, excessive current, accidental short circuits, and overheating—ensuring your devices and the battery remain stable, reliable, and safe in every charging scenario.

Charging temperatures above 50°C trigger automatic power reduction.

Discharging temperatures above 60°C prompt automatic output adjustment.

This ensures safe operation for both the device and the battery.
