Detailed Description

Running out of smartphone battery during a busy day can be frustrating, especially when you're travelling, working outdoors, attending university, or dealing with an unexpected power outage. The UGREEN PB312 25683 20000mAh Power Bank provides a convenient way to keep your essential devices powered wherever you go.

Its 20,000mAh capacity gives you considerably more battery reserve than a typical 5,000mAh or 10,000mAh portable charger. The PB312 is designed primarily for smartphones and everyday USB-powered electronics, while its 22.5W maximum output provides faster charging than basic 10W–12W power banks.

The power bank features a combination of USB-C and USB-A connectivity, making it suitable for both newer USB-C devices and accessories that still use traditional USB-A charging cables.

Whether you need additional battery for your iPhone, Samsung Galaxy, Android phone, tablet, wireless earbuds, smartwatch or other USB-powered accessories, the PB312 offers a straightforward portable charging solution.

20,000mAh High Capacity

The biggest advantage of the UGREEN PB312 is its 20,000mAh battery capacity.

This gives you enough portable energy for extended periods away from an electrical outlet. It is especially useful for customers who spend long hours outside the home or office.

The large capacity makes the PB312 suitable for:

• Smartphones
• Tablets
• Wireless earbuds
• Bluetooth speakers
• Smartwatches
• Portable gaming devices
• USB-powered accessories
• Other compatible electronics

As with all power banks, the actual usable output is lower than the nominal battery-cell capacity because energy is converted from the internal battery voltage to the output voltage.

---

22.5W Fast Charging

The PB312 supports up to 22.5W output, giving compatible smartphones considerably faster charging than conventional low-power power banks.

The available charging speed depends on the connected device and its supported charging protocol.

This makes it a good choice for users who want a balance between:

Large capacity + portable size + faster charging

Instead of carrying a basic power bank that only provides slow emergency charging, the PB312 is designed to provide a more useful fast-charging experience.

---

USB-C Connectivity

USB-C has become the standard charging connection for many modern smartphones, tablets and accessories.

The PB312 includes USB-C connectivity, allowing compatible devices to be charged using a USB-C cable.

It also makes recharging the power bank more convenient when paired with an appropriate USB-C wall charger.

---

USB-A Support

While USB-C is increasingly common, many users still own USB-A charging cables and accessories.

The PB312's USB-A connectivity provides broader compatibility with existing accessories.

You can therefore use it with many:

• Android phones
• Older smartphones
• Bluetooth headphones
• Wireless earbuds
• USB-powered accessories
• Portable speakers
• Charging cables

---

Ideal Everyday Power Backup

The UGREEN PB312 isn't designed only for emergency situations. Its 20,000mAh capacity makes it useful as an everyday portable charging companion.

Keep it in your:

• Backpack
• Laptop bag
• Travel bag
• Office drawer
• University bag
• Car emergency kit

It can provide convenient backup power when you don't have immediate access to a wall outlet.

---

Great for Travel

For travel, a 20,000mAh power bank provides a useful compromise between capacity and portability.

It can help keep your phone charged during:

• Long road trips
• Airport waiting
• Train journeys
• Hotel stays
• Business trips
• Outdoor activities
• Camping
• Day-long sightseeing

Before flying, always check your airline's current requirements for carrying lithium-ion power banks.

• Smartwatches
• Fitness trackers

Practical 20,000mAh Capacity

A 20,000mAh power bank can potentially provide several smartphone charges, depending on:

• Phone battery size
• Charging efficiency

• Phone usage during charging

Therefore, actual charging counts will vary from one device to another.
