Specifications

UGREEN's official specification lists a 48,000mAh / 153.6Wh capacity, five charging ports, dimensions of approximately 143 × 105 × 77mm, and a weight of approximately 1,637g.

Massive 48,000mAh / 153.6Wh Capacity

The UGREEN 25286 is designed for users who need substantially more portable energy than a conventional 10,000mAh or 20,000mAh power bank.

Its 48,000mAh / 153.6Wh capacity provides a large reserve for keeping multiple devices powered during long working sessions, trips, outdoor activities, or situations where wall outlets are unavailable.

It is particularly useful for:

• USB-C Laptops
• Smartphones
• Tablets & iPads
• Gaming Handhelds
• Cameras
• Bluetooth Speakers
• USB Accessories
• Mobile Workstations
• Emergency Backup

The actual number of device charges varies according to battery size, charging efficiency, operating load, and power conversion losses.

Up to 300W Total Charging Power

The UGREEN 25286 provides up to 300W total power output, enabling it to charge multiple high-power devices at the same time.

This is a major difference compared with ordinary power banks designed primarily for smartphones.

The high combined output makes the UGREEN 25286 suitable for users who may need to power combinations such as:

• Laptop + Smartphone + Tablet
• Two USB-C Laptops + Phone
• Gaming Handheld + Laptop + Accessories
• Camera Equipment + Tablet + Phone
• Multiple Devices During Outdoor Trips

Available charging power is distributed according to the ports and devices being used, so individual port output may decrease when several devices are connected simultaneously.

140W PD 3.1 USB-C Fast Charging

The primary USB-C1 port supports USB Power Delivery 3.1 and delivers up to:

• 28V / 5A – 140W
• 20V / 5A – 100W
• 15V / 3A
• 12V / 3A
• 9V / 3A
• 5V / 3A

It also supports PPS from 3.3V to 21V at up to 5A.

With up to 140W from a single port, the UGREEN 25286 can provide sufficient power for many high-performance USB-C laptops that require substantially more than typical 45W or 65W power banks can deliver.

Two Additional 100W USB-C Ports

In addition to its 140W USB-C connection, the power bank includes two more USB-C ports, each capable of delivering up to 100W in supported configurations.

USB-C2 and USB-C3 support:

• 20V / 5A
• 15V / 3A
• 12V / 3A
• 9V / 3A
• 5V / 3A
• PPS 3.3–21V / 5A

This gives the UGREEN 25286 enough flexibility to charge several demanding USB-C devices from one portable battery.

Two 22.5W USB-A Ports

Legacy USB devices aren't left behind.

Two dedicated USB-A ports support output of up to 22.5W for compatible equipment.

Supported output profiles include:

• 5V / 3A
• 9V / 2A
• 12V / 1.5A
• 10V / 2.25A

These connections are useful for smartphones, controllers, headphones, lighting, Bluetooth accessories, and other equipment that still relies on USB-A cables.

Charge Up to Five Devices

The UGREEN 25286 provides a total of five USB charging connections:

• 1 × USB-C – Up to 140W
• 2 × USB-C – Up to 100W Each
• 2 × USB-A – Up to 22.5W Each

This allows several compatible devices to be connected at once.

When multiple ports are active, the power bank automatically distributes its available output according to the connected devices and supported charging configuration.

Its maximum combined output is 300W.

140W Two-Way USB-C Charging

USB-C1 isn't only a high-power output.

The same connection also supports up to 140W input, allowing the power bank itself to recharge through USB Power Delivery 3.1.

This two-way functionality means one high-power USB-C port handles both:

• Up to 140W output to compatible devices
• Up to 140W input for recharging the power bank

A compatible high-wattage USB-C charger and suitable 5A E-Marker cable are required to achieve maximum charging performance.

Approx. 1.5-Hour Fast Recharge

Despite its enormous 48,000mAh capacity, UGREEN states that the power bank can be fully recharged in approximately 1.5 hours using a compatible 140W charger under its specified test conditions.

Actual recharge time can vary according to:

• Charger Output
• USB-C Cable Capability
• Battery Temperature
• Remaining Battery Level
• Operating Conditions
• Whether Other Devices Are Connected

The 140W input capability significantly reduces downtime compared with charging such a large battery from a conventional low-power charger.

Long-Life LiFePO4 Battery

Instead of conventional lithium-ion chemistry, the UGREEN 25286 uses LiFePO4 – Lithium Iron Phosphate battery technology.

UGREEN describes the cells as automotive-grade and states that they retain more than 80% of their original capacity after 3,000 charge cycles.

The longer cycle-life design makes the power bank especially useful for customers who plan to use it frequently for:

• Professional Work
• Home Backup
• Outdoor Activities
• Travel
• Gaming
• Content Creation
• Mobile Workstations

Smart Digital Display

The integrated smart LED display provides useful information about the power bank's operating status.

It can show:

• Remaining Battery Percentage
• Total Input Power
• Total Output Power
• Charging Status

This is especially useful when charging laptops and several devices simultaneously because you can quickly monitor how much power is being used and how much battery remains.

Built-In Three-Mode LED Light

The UGREEN 25286 incorporates an LED light for outdoor, emergency, and low-light situations.

Available modes include:

• Low Brightness
• High Brightness
• SOS Emergency Flashing

UGREEN's published testing lists approximately:

• Low Mode – Up to 150 Hours
• High Mode – Up to 115 Hours
• SOS Mode – Up to 115 Hours

Actual lighting runtime varies depending on remaining battery capacity and operating conditions.

Ideal for Laptop Charging

With 140W PD 3.1 output, the UGREEN 25286 is particularly suited to users who need portable laptop power.

Compatible device categories include:

• MacBook Pro
• MacBook Air
• High-Power USB-C Laptops
• Lenovo USB-C Laptops
• ASUS USB-C Laptops
• Dell USB-C Laptops
• HP USB-C Laptops
• Microsoft Surface Devices
• Chromebooks
• Other Compatible PD Laptops

UGREEN officially lists compatibility with MacBooks, USB-C laptops, smartphones, and tablets.

Actual charging speed depends on the connected laptop's supported USB-C Power Delivery profile.

Great for Gaming Handhelds & Gaming Setups

The large battery capacity and high USB-C output also make the UGREEN 25286 a strong option for portable gaming.

It can be used with compatible:

• Steam Deck
• ASUS ROG Ally
• Lenovo Legion Go
• MSI Claw
• Nintendo Switch
• USB-C Gaming Controllers
• Gaming Accessories
• Portable Monitors
• USB-C Hubs & Docks

Its large battery reserve can help extend gaming sessions when an AC outlet isn't readily available.

For gaming handhelds that support high-wattage USB-C charging, the power bank can provide substantially more power than basic smartphone-focused portable chargers.

UGREEN also highlights NTC temperature control and a V-0 flame-retardant design as part of the product's safety construction.

Integrated Carrying Handle

At approximately 1.64kg, the UGREEN 25286 is much heavier than a conventional pocket-sized power bank.

To make transportation easier, UGREEN integrates a dedicated carrying handle into the design.

This makes it better suited to:

• Work Bags
• Vehicle Storage
• Camping Gear
• Mobile Offices
• Photography Equipment
• Gaming Trips
• Emergency Power Kits

UGREEN also includes a non-slip base to help keep the unit stable during use.

Compact for Its Capacity

The power bank measures approximately:

143 × 105 × 77mm

and weighs approximately:

1,637g / 1.64kg.

While significantly larger and heavier than standard 10K or 20K power banks, the design provides an unusually large 48,000mAh capacity and 300W total output in a portable USB charging format.

No Wireless Charging

The UGREEN 25286 is focused on high-power wired charging and does not include wireless charging.

All device charging is handled through its:

• 3 × USB-C Ports
• 2 × USB-A Ports

For maximum performance, use compatible USB-C Power Delivery chargers, cables, and devices.

Important Air-Travel Note

The battery is rated at 153.6Wh, which is significantly larger than many conventional travel power banks.

Airline and aviation rules for batteries of this capacity can vary, so customers should check the current requirements of their airline and relevant aviation authority before flying with this product.

Do not assume that a 48,000mAh / 153.6Wh power bank will be accepted for air travel without restrictions or prior approval.
