## BigBlue Cellpowa100 (CP100) Review: A Compact LiFePO4 Portable Power Station That Punches Above Its Weight Finding a portable power station that balances portability with useful power output can be a challenge. The BigBlue Cellpowa100 (CP100) aims to solve this dilemma with its impressively compact 1.35kg (2.97 lbs) body, LiFePO4 battery chemistry, and 100W AC output — all at a price point of ¥19,489 on Amazon Japan. ### Long-Lasting LiFePO4 Battery At the heart of the Cellpowa100 is a lithium iron phosphate (LiFePO4) battery — the same chemistry used in electric vehicles. This battery type is known for its superior longevity, and BigBlue claims this unit can last up to 10 years or more. For a device that many will purchase as an emergency preparedness tool, this kind of lifespan is a significant advantage over standard lithium-ion alternatives. ### Ultra-Compact and Airline-Friendly Measuring just 13.5 × 8.5 × 15.6 cm (5.3 × 3.3 × 6.1 inches) and weighing only 1.35 kg, the Cellpowa100 is remarkably portable. Its 102.4Wh (32,000mAh) capacity falls within airline carry-on limits, making it an excellent travel companion for business trips and vacations. You can easily slip it into a backpack without adding significant bulk or weight. ### 100W Pure Sine Wave AC Output Despite its small size, the CP100 features a built-in AC outlet with a rated output of 100W and pure sine wave output. This means you can safely power small appliances like portable fans, mini refrigerators, electric blankets, and laptop chargers. The pure sine wave ensures compatibility with sensitive electronics. ### Versatile Charging Ports — Up to 5 Devices Simultaneously The Cellpowa100 offers a generous array of output ports for its size: 1 AC outlet, 1 USB-A port, and 3 USB-C ports. This allows you to charge up to 5 devices at once — ideal for keeping your smartphone, laptop, tablet, and other gadgets powered up simultaneously. The emphasis on USB-C ports is a welcome modern touch. ### Fast Charging and Pass-Through Capability Using the included PD 65W AC adapter and USB-C cable, you can fully charge the unit in approximately 1.8 hours. Pass-through charging is also supported, meaning you can charge the power station while simultaneously powering your devices — a practical feature for everyday use and emergencies alike. ### Built-In LED Light and Comprehensive Safety The integrated LED light offers four modes: high, medium, low, and SOS. This makes it a handy flashlight during power outages or nighttime outdoor activities. Safety is well addressed with a Battery Management System (BMS) that includes overload, overheat, over-discharge, overcharge, overcurrent, and short circuit protection — six layers of protection in total. ### Solar Panel Compatible For off-grid situations, the Cellpowa100 supports solar panel charging up to 40W. BigBlue recommends their own F35 solar panel (sold separately). This capability adds a crucial layer of versatility for camping, hiking, or disaster preparedness scenarios where grid power is unavailable. ### The Bottom Line The BigBlue Cellpowa100 is a well-designed compact portable power station that excels in portability and convenience. Its LiFePO4 battery ensures long-term reliability, and the array of ports and features — including pass-through charging and an SOS LED light — make it suitable for daily use, travel, and emergency situations. However, the 102.4Wh capacity does have its limits; it's not designed for powering high-draw appliances for extended periods. The product comes with a 2-year warranty and a beige two-tone color finish. Currently available on Amazon Japan for ¥19,489.
