45W PD Fast Charging
The FONENG PX138 supports up to 45W Power Delivery fast charging through its USB-C output. This allows compatible smartphones, tablets, and other supported USB-C devices to charge faster than with conventional low-power power banks.
The USB-C output supports multiple voltage profiles, including up to 20V⎓2.25A, while PPS support provides additional flexibility for compatible fast-charging devices.
20000mAh High-Density Battery
The PX138 uses a 20000mAh lithium-polymer battery built from two 10000mAh cells. FONENG’s high-density battery design allows the power bank to provide a large battery capacity while maintaining a relatively compact body.
This capacity makes the PX138 suitable for long days at university, work, commuting, travel, and other situations where access to a wall charger may be limited. Actual charging capacity available to connected devices will vary because of voltage conversion, charging efficiency, device battery size, and operating conditions.
Built-in Braided USB-C Cable
A built-in braided USB-C cable is integrated directly into the FONENG PX138. This allows compatible USB-C devices to be connected without carrying a separate cable, helping reduce clutter when using the power bank on the move.
The integrated USB-C cable supports both charging input and output, making it useful not only for charging connected devices but also for recharging the power bank through a compatible power adapter.
LCD Digital Battery Display
The built-in LCD digital display provides a clear indication of the remaining battery percentage. Instead of estimating available capacity from a few indicator lights, users can quickly see how much charge remains before leaving home, work, or starting a trip.
Compact and Portable Design
Despite its 20000mAh capacity, the FONENG PX138 measures approximately 102 × 71 × 29 mm and weighs around 330 g. Its compact shape is designed to be easy to hold and convenient to carry in backpacks, handbags, and travel bags.
The exterior also uses a metallic spray-painting process and refined mould design, giving the power bank a clean and modern appearance while maintaining a practical everyday form factor.
