Built for Heavy Users, Not Occasional Emergencies

Some power banks are fine for a quick top-up. The UGREEN PB312 is not one of those. This model is designed for:

• Professionals who rely on their phone all day
• Travelers dealing with long journeys or power outages
• Students and remote workers
• Content creators and field workers
• Anyone who can’t afford battery anxiety

With 20000mAh of capacity, you can move through your day confidently knowing you have multiple full charges available.

20000mAh Capacity – Real-World Power That Lasts

Capacity numbers only matter if they translate into real performance. The UGREEN PB312 delivers exactly that.

In everyday use, you can expect:

• 4–5 full charges for most smartphones
• 2+ charges for larger phones or light tablets
• Multiple recharges for smaller devices like earbuds

This makes it ideal for extended travel, busy workdays, or areas where access to power sockets is limited.

Two-Way Fast Charging – Faster for You, Faster for the Power Bank

One of the most practical features of the UGREEN PB312 is two-way fast charging.

What this means in daily use:

• Your phone charges faster than with standard power banks
• The power bank itself recharges much quicker
• Less waiting time between uses
• Better efficiency overall

Instead of spending half a day recharging your power bank, you’re back to full capacity faster and ready to go again.

Fast Charging Without Battery Damage

UGREEN doesn’t just focus on speed — it focuses on smart power delivery.

The PB312 automatically adjusts charging output based on:

• The device connected
• Battery level
• Charging stage

This ensures:

• Faster charging when safe
• Reduced heat buildup
• Better long-term battery health for your devices

You get speed without sacrificing safety.

Dual Device Charging – Power More Than One Device

The UGREEN PB312 supports charging multiple devices, making it ideal for multitasking or sharing power.

Perfect for:

• Charging your phone and earbuds together
• Powering a phone and a hotspot
• Helping a colleague or friend when their battery is dead

Each output is intelligently managed to keep charging stable and efficient.

UGREEN products are known for excellent build quality, and the PB312 continues that reputation.

• Solid, durable casing
• Clean, professional design
• Built to handle daily use and travel

It feels sturdy in the hand and reliable in the bag — not flimsy or disposable.

Despite its high capacity, the PB312 is designed to remain portable and practical.

• Slim enough for backpacks and laptop bags

• Easy to carry during travel or daily commutes

• Tablets
• Wireless earbuds

If it charges via USB, the PB312 is designed to handle it safely.

• Over-charging protection
• Over-discharging protection
