Client Background

A professional outdoor adventure Team (hereinafter referred to as the “client”) specializes in extreme outdoor projects such as high-altitude mountaineering, desert crossings, and rainforest expeditions. Each expedition lasts 5-15 days, and the team needs to carry various electronic devices including cameras, satellite phones, GPS locators, drones, and emergency lighting. Previously relying on traditional power banks, they faced issues such as insufficient battery life (only 1-2 days), single charging interface, and lack of emergency early warning functions. They had repeatedly missed rescue signals due to device power outages and encountered sudden severe weather due to failure to obtain timely weather warnings, posing significant safety hazards to the expeditions.

Project Challenges

1. Extreme environment adaptation: Stable power supply for devices is required under complex environments such as strong ultraviolet radiation at high altitudes, desert sand and dust, and rainforest humidity. Traditional power banks are prone to short circuits and sudden drops in battery life.
2. Multi-device power supply needs: The team’s carried devices cover interfaces including USB-A, USB-C, and Lightning, requiring simultaneous support for fast charging of multiple devices and compatibility with wireless charging devices.
3. Off-grid emergency support: In remote areas without signals or sunlight (e.g., rainy days, cave expeditions), a backup power generation method is needed to avoid complete power interruption.
4. Safety early warning and emergency response: Real-time weather warnings and distress functions are required, along with meeting the needs of nighttime lighting and temporary communication assistance.
5. Portability requirement: The product weight should be controlled within 1kg, with a compact size that does not occupy too much backpack space, suitable for long-distance hiking with load requirements.

Solution

The client purchased our PN-W29A Multi-Functional Solar Power Bank (16000mAh capacity). Relying on its integrated design of “power supply + emergency response + entertainment”, it accurately addresses the core pain points of outdoor adventures. The specific applications are as follows:

1. All-scenario power supply configuration: The product is equipped with a 16000mAh Grade A Li-polymer battery, supporting 4 power supply modes — solar charging (solar panel efficiency up to DC5V/240mA, fully charged in 6 hours under 25000LUX illumination), hand-cranked power generation (2W power, emergency charging available at 7200r/h hand-cranking speed), AC fast charging (40W input, fully charged in 3 hours), and wireless charging (5W/7.5W/10W/15W multi-power adaptation), completely eliminating off-grid dependence.
2. Multi-interface compatible fast charging: Equipped with Type-C input/output port, USB-A output port, built-in Lightning cable and USB-C cable, supporting simultaneous charging of 5 devices. The 40W fast charging power can charge a mobile phone to 60% in 30 minutes, meeting the emergency charging needs of satellite phones, drones and other devices.
3. Emergency early warning and safety functions: Built-in FM/NOAA/WB three-band radio (FM: 87.5-108MHz, WB: 162.400-162.550MHz), preset with 7 NOAA weather alert channels to automatically receive severe weather warnings; long-press for 3 seconds to activate the SOS flashing LED light, combined with a 2W high-brightness LED flashlight, featuring both lighting and distress signal functions. The 360° rotating antenna enhances signal reception stability.
4. Extreme environment protection: Adopting ABS+PC waterproof material with IPX6 waterproof and dustproof rating, it can resist rainforest downpours and desert sand and dust. The operating temperature range is -10℃~60℃, suitable for various extreme outdoor scenarios.
5. Lightweight and portable design: The product weighs only 560g with dimensions of 22cm×16cm×5cm, which can be easily placed in the side pocket of a backpack. Equipped with a non-slip handle, it is convenient to take and use during hiking and camping without additional load pressure.
6. Additional practical functions: Built-in 3W Bluetooth speaker supporting Bluetooth 5.3 connection, which can play navigation voices and team communication audio during expedition breaks, improving outdoor collaboration efficiency; the HD LED display real-time shows remaining power, charging power, and radio frequency, making operation intuitive and easy to understand.

Project Results

1. All-time power guarantee: During 15 extreme expeditions, the PN-W29A operated without failure. In sunless environments, hand-cranked power generation maintained continuous power supply for core devices (satellite phones, GPS), reducing the device power outage rate from 35% to 0; in a fully charged state, it can charge a satellite phone 4 times, a GPS locator 6 times, a drone 2 times, and a mobile phone 3 times, fully covering the needs of long-cycle expeditions.
2. Significant improvement in safety factor: The NOAA weather warning function successfully avoided 3 sudden rainstorms and 2 sandstorms. The SOS flashing light helped the rescue team quickly locate during 1 high-altitude lost incident, increasing the safety factor of expeditions by 80%.
3. Efficient multi-scenario adaptation: The 2W LED flashlight meets the lighting needs of night camping and cave exploration with a battery life of over 30 hours; the Bluetooth speaker and radio functions realize information transmission and team collaboration in signal-free areas, enhancing the adventure experience.
4. Meeting portability and durability requirements: The 560g lightweight design did not increase the team’s load pressure. The waterproof and dustproof performance was tested in rainforest and desert environments with no equipment damage, achieving a 100% product integrity rate.

Client Feedback

“The PN-W29A has completely subverted our perception of outdoor power banks. It is not just a power supply device, but also our ‘safety steward’. The solar + hand-cranked dual power generation mode solves the power anxiety in extreme environments, the NOAA weather warning allows us to avoid risks in advance, the SOS function and high-brightness flashlight give us confidence in emergencies, and even the Bluetooth speaker can improve team collaboration efficiency. Lightweight, durable, and fully functional, it is an indispensable core equipment for every extreme expedition.” — Leader of the client’s adventure team
