The Jiayou Thunder 7 is a 10000mAh fast charging power bank built to keep your phone powered through a full day away from a wall socket. Its 22.5W maximum output gives modern smartphones a quick top-up, and the built-in Type-C and Lightning cables mean you don’t need to carry a separate cable.

If you’ve been looking for a dependable Jiayou power bank, the Thunder 7 combines high capacity with a smart LED display that shows battery percentage, voltage and wattage in real time. You always know how much charge is left and how fast your device is charging.

It suits daily commutes, campus days, office desks and long trips, anywhere your phone, earbuds or other small devices need reliable backup power.

Key Features

• 10000mAh / 37Wh lithium polymer cell: The high-density cell stores plenty of energy for multiple recharge cycles of your phone and other handheld devices, so one carry-along battery covers a full day.

• 22.5W maximum output: Output runs at 5V/4.5A, 9V/2A or 12V/1.5A, so compatible devices get a fast top-up without long waits.

• Built-in Type-C and Lightning cables: Both cables are attached and retract neatly into the body, which means no cable clutter and no forgotten cable at home.

• PD, SCP and QC 3.0 support: Multiple fast charging protocols let the power bank talk to a wider range of phones and accessories.

• Dual USB-A output ports: Along with the two attached cables, you can power several devices at once, which is handy when travelling with friends or family.

• Smart LED display: Percentage, voltage and wattage are shown on screen, so you can plan your charging instead of guessing.

• Multi-layer safety protection: The cell protection grid and intelligent safe electricity system help keep charging stable and your devices protected.

• 18W fast recharge input: Charging the power bank itself over USB Type-C (5V/3A or 9V/2A) means less time tied to a wall socket.

Why Choose This Jiayou Thunder 7 10000mAh Fast Charging Power Bank
