CH191 Dual Cable Power Bank USB-C Lightning | OEM

Description

CH191 Power Bank is a compact 10000mAh fast-charge power bank with integrated USB-C and Lightning cables for convenient daily charging.

Frequently Asked Questions: CH191 Dual Cable Power Bank

1. Why does the CH191 use two 5000mAh cells instead of a single 10000mAh cell?

The CH191 uses a dual-cell configuration (two 5000mAh cells in parallel) to achieve a more compact form factor (97x65x27mm) while maintaining 10000mAh total capacity. Dual-cell design also improves thermal distribution — heat is spread across two cells rather than concentrated in one — and provides better discharge stability under heavy load. The dual 5000mAh cells are 3.85V high-voltage lithium polymer cells rated at 38.5Wh total energy.

2. What are the two built-in cables on the CH191 and which devices does each one serve?

The CH191 features two integrated cables: a USB-C cable that supports bidirectional charging (input and output) at up to 12V/1.67A for modern Android phones, iPads, and USB-C devices; and a Lightning cable that provides 5V/2.4A output for iPhones, AirPods, and older Apple devices. Both cables are permanently attached, eliminating the need to carry separate cables and ensuring you always have the right connector available.

3. Can the CH191 charge three devices simultaneously using both cables and the USB-A port?

Yes, the CH191 supports triple-device simultaneous charging through the USB-C cable, Lightning cable, and USB-A port. The USB-A port delivers up to 22.5W (supporting QC3.0 and SCP protocols), while the USB-C cable provides up to 12V/1.67A and the Lightning cable provides 5V/2.4A. The total combined output is managed by an intelligent power distribution IC that prevents overcurrent and maintains stable charging across all three ports.

4. What is the rated capacity of 6300mAh (5V/2.4A) and how does it differ from the 10000mAh cell capacity?

The 10000mAh rating refers to the battery cell capacity at 3.85V. The 6300mAh rated capacity represents the actual usable output at 5V/2.4A after voltage conversion losses, thermal losses, and circuit overhead. This is a standard industry measurement — all power banks deliver approximately 60-65% of their cell capacity as usable output due to the voltage step-up from 3.85V to 5V and conversion efficiency. The CH191’s 6300mAh rated output provides approximately 1.5-2 full smartphone charges.

5. How does the CH191’s compact 97x65x27mm body compare to similar dual-cable power banks?

The CH191 is notably compact for a dual-cable 10000mAh power bank. Most competitors with integrated dual cables measure 110-130mm in length. The 97mm length is achieved through the dual-cell parallel layout and tight PCB integration. At 27mm thickness, it fits comfortably in a jacket pocket or bag side pocket. The dual integrated cables fold flush into the body, maintaining a clean profile without protruding connectors.

6. What safety protections does the CH191 include for the integrated cables?

The CH191 includes comprehensive safety protection: overcurrent protection on each cable output, short-circuit protection that instantly cuts power if a fault is detected, overvoltage protection that prevents damage from voltage spikes, temperature monitoring with automatic shutdown if internal temperature exceeds 60 degrees Celsius, and input overcurrent protection during recharging. The cables use flame-retardant TPU jacketing rated to UL94 V-0 standard.

7. What OEM customization options does the CH191 offer for B2B distributors?

The CH191 is designed for B2B distribution targeting retail chains, corporate gifts, and promotional markets. OEM options include custom logo printing on the front and back panels, custom shell colors (minimum 500 units per color), branded packaging with company design, and optional cable type customization (e.g., replacing the Lightning cable with a micro-USB cable for specific markets). MOQ is 500 units. The dual-cable design appeals to buyers who need Apple and Android compatibility in one product.
