UGREEN PB312 20000mAh 22.5W Power Bank 25683

Product Overview

The UGREEN PB312 20000mAh 22.5W Power Bank 25683 is designed for users who need reliable backup power for phones, tablets, earbuds, smartwatches, cameras, speakers, and everyday USB-powered devices. With a large 20000mAh battery capacity, this power bank is made for long days, travel, university, office use, commuting, road trips, and emergency charging during power outages.

This model gives you a practical mix of speed and capacity. The two USB-A ports support up to 22.5W fast charging, while the USB-C port supports up to 20W input and output, allowing the power bank to charge your device and also recharge itself through the same Type-C port. That makes it more useful than basic power banks that only support slow output and slow recharging.

The 3-port design allows you to charge up to three devices at the same time, making it helpful for users who carry more than one device or need to share power with family, friends, or coworkers. A clear digital LED display shows the remaining battery level, so you can check the power status before leaving home, office, or class.

If you want a power bank that is not limited to emergency charging only, the UGREEN PB312 is a strong daily-use option. It offers high capacity, fast wired charging, USB-C two-way charging, multiple outputs, low-current device support, and a travel-ready design in one practical portable charger.

Key Features

20000mAh High-Capacity Backup Power
The 20000mAh battery capacity gives you strong backup power for long days when wall charging is not available. It is useful for travel, business trips, university, outdoor use, road trips, and daily emergency backup.

22.5W USB-A Fast Charging Output
Both USB-A output ports support up to 22.5W fast charging for compatible devices. This is useful for phones and accessories that still use USB-A charging cables, giving faster performance than standard 5W or 10W power banks.

20W USB-C Two-Way Charging
The USB-C port supports up to 20W output for charging compatible devices and up to 20W input for recharging the power bank. This two-way charging feature makes the PB312 more practical for daily use because one USB-C port handles both charging directions.

Charge Up to 3 Devices at Once
With 2 USB-A ports and 1 USB-C port, this power bank can charge three devices at the same time. You can charge a phone, earbuds, and smartwatch together, or share power with another user when needed.

Digital LED Battery Display
The built-in digital display shows the remaining battery level clearly. This is much more convenient than guessing from small indicator lights, especially before travel, office use, or power outages.

20W Faster Recharging for the Power Bank
When used with a compatible 20W PD charger, the PB312 can recharge faster than ordinary low-input power banks. This helps reduce waiting time and keeps the power bank ready for your next use.

Low-Current Mode for Small Devices
The power bank supports low-current charging for smaller accessories such as earbuds, smartwatches, fitness bands, and similar low-power devices. This makes it more versatile than power banks designed only for phones.

Pass-Through Charging Support
The PB312 supports pass-through charging, allowing connected-device charging while the power bank is also being recharged. This is useful when you have limited wall sockets and need to manage multiple devices.

Compact for a 20000mAh Power Bank
Despite its large capacity, the PB312 has a manageable size for bags, backpacks, office drawers, travel pouches, and car storage compartments. It is more portable than many heavy high-capacity power banks.

Safer Everyday Charging
The power bank is designed with intelligent voltage and current management, over-temperature protection, and a protective shell design for safer daily charging when used with compatible devices and cables.

Useful During Load Shedding & Travel
For users in Pakistan, this power bank is especially helpful during load shedding, long commutes, university classes, business travel, and emergency situations where phone battery backup is important.
