PowerBank X-power SI30A7QLX silver (30000mAh, PD130W, LED, seamless fast passthrough charging, 21700 Li-pol Cylindrical battery, 100w cable) — a powerful and modern power bank from the Sigma Mobile brand, designed for those who need a reliable power source on the go, at work, or at home. The SI30A7QLX model combines a large capacity of 30000 mAh and a maximum output power of up to 130 W, allowing you to charge laptops, smartphones, and other devices at high speed.

Key Features

• Capacity: 30000 mAh.
• Maximum Output Power: up to 130 W (total for connected devices).
• Ports: USB-C1 (input/output), USB-C2 (output), USB-A (output).
• Port Output Power: USB-C1 up to 100 W (output), USB-C2 up to 30 W (output), USB-A up to 22.5 W (output).
• Input Power: maximum input power of SI30A7QLX — 60 W; for full fast charging, it is recommended to use a PD charger of at least 65 W (full charge to 100% is possible in 2 hours 30 minutes when using a compatible cable and charger with Power Delivery 100 W support).
• Battery: six 21700 cylindrical Li-Polymer cells (21700 cylindrical batteries), ensuring stable power under high loads and a longer service life (up to 1000+ cycles).
• Weight and Portability: only 570 grams, compact dimensions for convenient transport.
• Included: 100W E-Mark cable included.
• Display: LED display shows input/output power, low current mode, and protocol status.
• Supported Protocols: PD 3.0, QC 3.0, AFC, FCP.
• Protection: built-in protection system against overheating, overvoltage, and short circuit.

Ports and Simultaneous Charging

The SI30A7QLX has three connectors, allowing you to charge up to three devices simultaneously, provided that the total power does not exceed 130 W. The main USB-C1 supports up to 100 W output power and up to 60 W input power; USB-C2 — up to 30 W; USB-A — up to 22.5 W. This makes it possible, for example, to simultaneously charge a MacBook and a smartphone: one device can receive up to 100 W, the other — up to 30 W.

Fast Charging and Lifespan

Despite its large capacity, the SI30A7QLX power bank can be fully charged in 2 hours 30 minutes when using a Power Delivery 100 W charger and a compatible cable. New 21700 Li-Polymer cells better withstand high currents during fast charging, wear out slower, and have a longer service life — over 1000 cycles. 21700 batteries are also used in power tools and electric vehicles, which emphasizes their reliability and stable operation under load.

Seamless Passthrough Charging

One of the important advantages of the SI30A7QLX is seamless passthrough charging: when switching between charging the power bank from an external source and powering connected devices, the current supply is not interrupted. When external power is lost, the power bank automatically continues to power connected devices, and when external power is restored — it instantly returns to charging mode without failures. This is especially useful for routers, smart home systems, CCTV cameras, medical devices, and server equipment.

LED Display and Additional Functions

The LED display shows input and output power, low current mode, and protocol status, allowing you to control the charging process and optimally distribute power consumption. The power bank is equipped with protection against overheating, overvoltage, and short circuit for safe use with modern electronics.

Recommendations and Compatibility

The SI30A7QLX is compatible with a wide range of devices thanks to its support for PD 3.0, QC 3.0, AFC, and FCP standards. It is recommended to use PD chargers with at least 65 W for optimal charging. The model is ideal for mobile professionals, travelers, and users who need a stable power supply for laptops, smartphones, tablets, and peripherals.

Additional materials and demonstration videos are available on the official Sigma Mobile support website: video on charging laptops and smartphones, video on low current mode, video on seamless passthrough charging and video on power distribution between ports.
