Detailed Description

Whether you're travelling, working, studying, commuting or simply dealing with frequent power interruptions, having enough battery power for your smartphone has become essential. The UGREEN PB505 35340 provides a substantial 20,000mAh battery capacity in a portable form factor, giving you significantly more backup power than typical 5,000mAh or 10,000mAh power banks.

Its biggest convenience feature is the built-in USB-C cable. Instead of remembering to pack a separate cable, you can simply pull out the integrated cable and connect your compatible USB-C device. The integrated cable is designed to reduce cable clutter while remaining available whenever you need it. UGREEN describes it as a durable, tangle-free built-in USB-C charging solution.

The PB505 supports up to 22.5W output, allowing compatible smartphones to charge considerably faster than standard 5W or 10W portable chargers. It also supports two-way fast charging, meaning the power bank itself can be recharged through its USB-C connection.

---

20,000mAh High-Capacity Battery

The 20,000mAh capacity is the main reason to choose the PB505 over a smaller portable charger.

Its internal battery is rated at approximately 74Wh, based on 3.7V × 20,000mAh.

This gives you enough stored energy for multiple smartphone charging sessions, making it particularly useful for:

• Long working days
• University and college
• Business trips
• Road trips
• Travel
• Outdoor activities
• Emergency backup
• Areas with unreliable electricity

Actual charging cycles vary depending on your phone's battery capacity, charging efficiency, usage while charging and conversion losses.

---

Built-in USB-C Charging Cable

The integrated USB-C cable is one of the PB505's most useful features.

You don't need to carry a separate USB-C cable every time you take the power bank with you. Simply release the cable from the power bank and connect it directly to a compatible device.

This is particularly useful for:

• USB-C smartphones
• Android phones
• iPhone models with USB-C
• Tablets
• Wireless earbuds
• Portable gaming devices
• Other USB-C accessories

The built-in cable is designed to stay attached to the power bank, helping prevent the common problem of forgetting or losing your charging cable.

---

Up to 22.5W Fast Charging

The PB505 provides up to 22.5W maximum output through its supported charging interfaces.

The built-in USB-C cable/USB-C output supports:

• 5V / 3A
• 9V / 2.22A
• 12V / 1.67A
• 10V / 2.25A

with a maximum output of 22.5W. The USB-A output also supports up to 22.5W.

The actual charging speed depends on the connected smartphone and its supported charging protocols.

---

Three Charging Outputs

The PB505 offers three ways to connect your devices:

1. Built-in USB-C cable
2. USB-C port
3. USB-A port

This gives you considerably more flexibility than a power bank with a single output.

You can use the built-in cable for your primary smartphone while keeping the USB-C and USB-A ports available for other compatible devices.

The PB505 is designed to support charging of up to three devices simultaneously, although available power is shared when multiple outputs are being used.

---

USB-C Port

In addition to the integrated USB-C cable, the PB505 has a separate USB-C interface.

This is useful if:

• Your built-in cable is already being used
• You need to charge a second USB-C device
• You have a longer USB-C cable
• You need a particular cable type for a specific device

The USB-C interface can also be used to recharge the power bank.

---

USB-A Compatibility

The PB505 retains a traditional USB-A output, making it compatible with many existing charging cables.

This is useful for customers who still have:

• USB-A to Lightning cables
• USB-A to USB-C cables
• Micro-USB cables
• USB-A accessories
• Older smartphones and electronics

The USB-A output supports up to 22.5W under compatible charging conditions.

---

Battery Level Display

The PB505 includes a digital battery-level display, allowing you to check the remaining power without guessing.

This is particularly useful with a 20,000mAh power bank because you can see when it needs to be recharged before leaving home.

Instead of relying on a simple LED indicator, the display provides a clearer indication of remaining battery status.

---

The exact charging speed still depends on the connected device, cable and protocol negotiation.

---

Two-Way Fast Charging

The PB505 isn't only capable of quickly charging your devices—it can also recharge itself through USB-C.

Its USB-C input supports up to 20W input:

• 5V / 3A
• 9V / 2.22A

UGREEN lists an approximate recharge time of around six hours using a 20W PD charger.

116 × 70 × 30mm

and a weight of approximately:
