Portable 40,000mAh Power Bank for Fast Charging Android & iOS Devices

The Breakdown That Counts

【Easier to Charge】 With 2 USB-A ports and 1 USB-C port, this ZZI portable charger can simultaneously charge up to three devices. It charges an iPhone 15 to 75% and a Samsung S23 to 63% in just 30 minutes, ensuring a quick refill of power. When using multiple ports together, the total power output is 15W. The LED display shows the current battery charge status, input, and output, helping you avoid guesswork.

【Power in Your Pocket】 Lighter and smaller than most power banks, this portable charger only weighs 11.01oz (less than two iPhone 15s), making it easy to carry in your bag or pocket. With a 40000mAh battery, your device stays fully charged all day. Note: Portable chargers with this capacity are not allowed on airplanes.

【Mini-sized】 Collaborating with leading battery energy labs over 2.5 years, we developed a new high-energy, ultra-compact battery cell. Our product passed all 28 safety tests and maintains over 80% battery health after 3 months. With an 80% increase in density, it's 30% smaller than other portable chargers with the same capacity.

【Safe, Powerful】 Equipped with an intelligent AI chip, this charger automatically controls temperature and executes 200 protections per second. This reduces the risk of overheating by 90% for a safer user experience. Additionally, the built-in smart circuitry protects against overheating, over-voltage, overloading, short-circuits, and overcharging.

【Handy Stand】 ZZI conducted a survey involving 2,000 individuals and found that 70% always carry a power bank when going out, and 30% prefer phone cases with brackets for easier screen viewing. Based on this, we designed the N7 portable power bank with a telescopic bracket to free your hands when needed. After two months of user testing by nearly 1,000 participants, the N7 received unanimous positive feedback.

【Universal Compatibility】 This charger supports PD3.0, QC2.0, QC3.0, DCP, and FCP protocols, making it compatible with a wide range of devices, including iPhone 16/16 Plus/16 Pro/16 Pro Max/15/15 Plus/15 Pro/15 Pro Max/14/13/12/11, Samsung Galaxy, and Google Pixel.
