The included accessories were minimal: a Type-C to Type-C charging cable and a multilingual user manual. While some power banks include a wall adapter, the XDIGI PB21 doesn't; you'll need to provide your own.

Charging Performance and Features
Fully charging the XDIGI PB21 from empty took approximately 3 hours and 30 minutes using a standard wall adapter. This is a reasonably fast charge time considering its massive 120,000mAh capacity.

The power bank boasts three ports: one USB-A (30W output), one USB-C (30W output), and a Type-C port with 100W input/output. This versatility ensures it can charge a wide range of devices quickly.

Charging a standard Android phone took just over an hour and 10 minutes. It also provided multiple full phone recharges, highlighting its impressive capacity.

Compatibility and Safety
The XDIGI PB21 worked well with various devices, including phones, tablets, and even some smaller laptops. However, it might not be powerful enough for high-power devices like gaming laptops.

Safety features include overheating protection, short-circuit protection, and input/output over-current protection. This ensures safe and reliable charging.

Overall Verdict
The XDIGI PB21 is a well-built, high-capacity power bank with a sleek design and a user-friendly interface. Its multiple ports and fast-charging capabilities make it versatile and convenient.

While the price point is slightly high, the quality and performance justify the cost for users who need a reliable and powerful portable charging solution. Its lack of included cables is a minor drawback.
