Massive 30,000mAh Capacity

It can provide backup charging for compatible smartphones and other USB devices throughout the day, making it particularly useful during travel, long working hours, outdoor activities and locations where mains electricity is not readily available.

The CALUS FAST309 supports Power Delivery (PD) fast charging with up to 22.5W output, helping compatible devices recharge more quickly.

This makes it a practical choice when you need to restore battery power without waiting as long as you would with a basic low-output power bank.

Note: Actual charging speed depends on the connected device, cable, charging protocol supported by the device and the selected output.

Digital LED Battery Display

Never guess how much power remains.

The built-in LED digital display provides a clear battery-percentage reading, allowing you to check the remaining charge at a glance.

This is especially useful when travelling because you can see when the power bank itself needs to be recharged before heading out.

Built-In Charging Cables

The CALUS FAST309 includes integrated charging cables built into the power bank, giving you a convenient all-in-one charging solution.

Instead of having to carry multiple loose cables everywhere, the integrated design keeps the charging connections together with the power bank.

Charge Multiple Devices

With its multiple charging outputs, the CALUS FAST309 can charge more than one compatible device at the same time.

This is particularly convenient when travelling with several devices, such as a smartphone, tablet or wireless headphones.

Built for Travel and Intensive Use

The combination of 30,000mAh capacity, fast charging, integrated cables, digital battery display and carrying loop makes the CALUS FAST309 particularly suitable for people who spend long periods away from convenient power outlets.

• Camping and trips
• Daily commuting
• Emergency backup power

• Charging headphones and other USB devices

Its all-in-one design is intended for users who want high-capacity backup power without carrying a separate charger and multiple loose cables.
