The anthracite finish is durable and unobtrusive for everyday carrying, while the multiple outputs support simultaneous charging of more than one device.

Suitable for

• Recharging smartphones and tablets during travel or commuting
• Powering USB-powered accessories such as Bluetooth headphones or portable speakers
• Providing backup power for longer outings, events or work away from mains power
• Charging multiple devices at once (one USB-C and two USB-A devices)

When it may not be suitable

This power bank is intended for charging consumer USB devices and is not designed as a replacement for laptop batteries that require high-wattage, dedicated charging protocols. Devices requiring specific fast-charging standards at high wattages may not charge at their maximum speed depending on the device’s and cable’s supported protocols. The physical size and weight associated with a 20000mAh capacity may be heavier than lower-capacity models if minimal weight and compactness are the priority.

Key specifications

• Battery capacity: 20000mAh
• Output ports: 1 × USB-C, 2 × USB-A
• Color/finish: Anthracite
• Use case: Portable charging for smartphones, tablets and USB-powered devices

How to use

Connect the power bank to your device using an appropriate USB-C or USB-A to device cable. Start charging by selecting the correct output port; most devices will begin charging automatically when connected. Recharge the power bank itself via the USB-C input using a compatible charger and cable. Observe charging indicators on the device or power bank to monitor remaining capacity and charging progress. For safe operation, use cables and adapters that match your devices’ charging specifications.

What to consider before purchase

• Check your device’s charging connector type and required charging protocol to ensure compatibility with USB-C or USB-A outputs
• Consider the weight and dimensions associated with a 20000mAh capacity if you prioritise portability
• Confirm whether your devices require higher wattage fast charging that the power bank may not provide

Usage recommendations

Use the USB-C port when charging USB-C devices for best compatibility, and distribute multiple devices across the USB-A outputs to preserve charging efficiency. Recharge the power bank after each use to keep it ready for travel, and store it in a dry, temperate place to prolong battery life.
