Client Background

Mr. Li Wei (hereinafter referred to as the “client”) is an experienced overlanding enthusiast and amateur photographer based in Shanghai, China. He frequently embarks on self-drive expeditions with his family across remote regions of China, such as the Tibetan Plateau, the deserts of Xinjiang, and the rainforests of Yunnan. These trips typically last 10-20 days, requiring reliable power for critical equipment including a portable fridge for food preservation, camera and drone gear, camping lights, laptops, and various communication devices. Previously relying on a combination of small power banks and his car’s inverter, he faced constant challenges: inability to run the fridge overnight without draining the car battery, insufficient power for camera equipment recharge over multi-day stops, and no reliable backup for essential devices during emergencies or when the vehicle was off.

Project Challenges

• Extended Off-Grid Independence: Needed a power source to sustain a 12V portable fridge (40W), camera gear, and lighting for a minimum of 2-3 days without any vehicle recharge, especially during stationary camping.
• High-Power Device Compatibility: Required to safely power devices with higher wattage demands, such as an electric cooking pan (800W) for meal preparation and a small projector (100W) for family entertainment.
• Harsh Environment Resilience: The power solution must perform reliably in diverse and extreme conditions encountered on Chinese roads—high-altitude cold on the Tibetan Plateau, intense heat and dust in the Taklamakan Desert, and high humidity in Southern China.
• Family-Centric Safety & Convenience: As a family man, he prioritized safety (stable battery chemistry), quiet operation (not disturbing wildlife or camp peace), and ease of use for all family members.
• Dual-Use Functionality: Sought a system that was vital for adventures but could also serve as a substantial power reserve for his apartment during occasional urban power outages, a growing concern in his area.
• Space-Efficient Portability: The unit needed to fit conveniently within his SUV’s packed cargo area without adding excessive weight or bulk.

Solution

The client selected our Portable 1024Wh / 1600W LiFePO4 Battery Pack. Its robust capacity, durable LiFePO4 battery, and high-power output directly addressed his core needs for both exploration and home readiness.

1. Long-Cycle Life LiFePO4 Battery: The 1024Wh capacity with over 3000-cycle lifespan provided the essential “power reservoir” for long trips. The LiFePO4 chemistry offered superior thermal stability and safety—a critical factor for family use—and maintained reliable capacity in the sub-zero temperatures of high-altitude locations.
2. High-Wattage Output for Comfort: The 1600W continuous (3200W surge) pure sine wave inverter allowed him to power not just sensitive electronics, but also higher-wattage appliances like the electric cooking pan and projector, significantly enhancing camping comfort and experience.
3. Core Application – Fridge & Camera Power: The battery reliably powered his 40W portable fridge for over 24 hours on a single charge while simultaneously charging multiple camera batteries, drones, and phones via the numerous USB and AC ports.
4. Flexible Recharging Strategy: Using the battery in tandem with his vehicle’s alternator (via a DC charger) and a supplementary 200W foldable solar panel (purchased separately), he established a sustainable power cycle. He could recharge while driving or during sunny camp days, achieving near-indefitive off-grid capability.
5. Seamless Home Integration: During a planned 8-hour maintenance blackout in his apartment complex, the unit effortlessly powered his family’s Wi-Fi router, LED lights, a fan, and charged all personal devices, proving its value as a home emergency asset.

Project Results

• Transformed Camping Experience: On a 15-day Sichuan-Tibet highway journey, the battery pack ensured their portable fridge ran continuously, preserving fresh food and drinks. It fully supported daily photography work and enabled family movie nights with the projector, greatly enhancing trip satisfaction.
• Achieved True Energy Independence: The system eliminated anxiety over finding power sources. In Muli County, where they stayed at a scenic spot for three days without driving, the solar panel successfully replenished 60-70% of the battery’s capacity daily, allowing all devices to function normally.
• Reliability in Extreme Conditions: The unit operated flawlessly at altitudes above 4,500 meters in temperatures around -5°C, with no noticeable performance drop, unlike previous lithium-ion power banks he had used.
• Quantified Power Security: The client calculated that on a full charge, the unit could: 1) Run his fridge for ~24 hours, 2) Fully recharge his DSLR camera batteries 15+ times, 3) Power the projector for 8+ hours, or 4) Keep essential home devices (lights, router, phone) running for over 12 hours.
• Verified Home Readiness: The successful deployment during the home power outage provided immense peace of mind, validating the investment as a dual-purpose tool for adventure and security.

Client Feedback

“This power station is a game-changer for my family’s adventures and our peace of mind at home. On the road, it’s our mobile power grid—keeping our food fresh, our gear charged, and even adding a touch of luxury with hot meals and movies under the stars. The peace of mind from knowing we have reliable, safe power in the middle of nowhere is priceless. Back in Shanghai, it instantly became our most trusted backup during blackouts. It’s incredibly well-built, easy to use, and just works. I was so impressed that I’ve actively recommended it to three friends: one who owns a tea plantation in Fujian (for powering tools), another who is a fellow overlander, and my neighbor who is concerned about urban power resilience. They all ended up buying one and are equally satisfied.”
