Ugreen 10000mAh Two-way Fast Charging Power Bank – PB502

The Ugreen PB502 delivers efficient portable charging in a compact, streamlined design. This versatile power bank combines fast charging technology with practical features for users seeking reliable on-the-go power solutions.

Dual-Port Fast Charging Output

The PB502 features strategically designed output options:

• USB-C Port: Supports Power Delivery protocol with up to 20W output
• USB-A Port: Delivers Quick Charge technology with up to 22.5W output
• Smart Power Distribution: Automatically allocates appropriate power to each connected device
• Combined Output: 15W total when both ports are used simultaneously

This dual-port configuration enables the PB502 to efficiently charge a wide range of devices including smartphones, tablets, wireless earbuds, and portable gaming accessories. Additionally, the intelligent power management system identifies connected devices and provides optimized charging parameters for each specific model.

Two-Way Fast Charging Technology

The PB502 incorporates advanced bidirectional fast charging capabilities:

• Fast Input: Recharges at up to 20W via Power Delivery through USB-C port
• Quick Recovery: Approximately 3 hours to recharge from 0% to 100% (with 20W adapter)
• Pass-Through Function: Simultaneously powers connected devices while recharging

This two-way fast charging technology minimizes downtime between uses, ensuring the power bank remains ready when needed. Furthermore, the pass-through charging function allows the PB502 to serve as a charging hub when limited wall outlets are available.

Ultra-Slim Profile Design

The Ugreen PB502 features an exceptionally thin form factor:

• Dimensions: 142 × 70 × 15mm (5.6″ × 2.8″ × 0.6″)
• Weight: 194g (6.8oz)
• Surface: Smooth matte finish resistant to fingerprints
• Edges: Gently curved for comfortable handling

Despite its slim profile, the PB502 houses a 10000mAh battery sufficient to fully recharge an iPhone 13 approximately 1.8 times or a Samsung Galaxy S22 about 1.7 times. Moreover, the streamlined design slips easily into pockets and bags without creating unsightly bulges or adding significant weight.

Smart Digital Display

The PB502 incorporates a precision digital display that provides:

• Numerical percentage indicator showing exact remaining capacity
• Charging indicator during device powering
• Input status during power bank recharging
• Automatic display timeout to conserve power

This informative display eliminates guesswork when managing power resources. Consequently, users can make informed decisions about device usage patterns based on precise remaining capacity data.

Comprehensive Safety System

The Ugreen PB502 integrates multiple protection mechanisms:

• Temperature regulation prevents overheating during rapid charging
• Voltage monitoring maintains stable output across varying battery levels
• Current limitation protects against potentially damaging power surges
• Short-circuit protection automatically disconnects power flow when hazards are detected
• Cell monitoring system maintains battery health over extended use

These layered safety measures operate continuously to protect both the power bank and connected devices. Additionally, premium lithium polymer cells with enhanced chemistry provide stable performance throughout the product’s operational life.

Durable Construction

The PB502 is engineered for longevity:

• Impact-resistant outer shell withstands daily handling
• Reinforced port structures maintain connection integrity
• High-quality internal components selected for extended lifespan
• Premium battery cells rated for 500+ charge cycles with minimal capacity loss

Each design element contributes to the overall reliability of the PB502. Subsequently, the power bank maintains consistent performance characteristics even with regular daily use across varied environmental conditions.

Ideal Users

The Ugreen PB502 is particularly well-suited for:

• Daily commuters who value the ultra-slim 15mm profile and 194g weight – the compact design slips easily into pockets or small compartments without adding significant bulk
• Business professionals requiring quick device recharging between meetings – the 20W output can restore compatible smartphones from 0% to 50% in approximately 30 minutes
• Users of multiple device types – the combination of USB-C and USB-A ports accommodates both newer and legacy devices without requiring adapters
• Frequent travelers seeking reliable backup power in a compact form factor – the durable construction withstands transport conditions while providing dependable performance
