For hikers, campers, road-trippers, and anyone who demands genuinely cold refreshments on the go, the Chillbee Sofichill 22 Portable Backpack Fridge is set to revolutionize outdoor cooling. Unlike traditional coolers that rely on melting ice, this innovative backpack features a built-in compressor, delivering true refrigeration that keeps your food and drinks perfectly chilled or even frozen, no matter where your adventures take you.


Project Overview

  • Name and Creator: Sofichill, Soft-Sided Compressor Backpack Cooler by ChillBee

  • What It Is: The Sofichill 22 is a soft-sided, portable backpack cooler equipped with a powerful compressor, providing active cooling and precise temperature control down to 5°F (-15°C). It eliminates the need for ice, freeing up valuable space, reducing weight, and ensuring your contents stay cold for extended periods.


Key Features

  • True Compressor Cooling: Unlike passive coolers or those relying on ice packs, Sofichill utilizes a built-in compressor with air-cooling technology. This allows it to actively cool its contents, reaching temperatures as low as 5°F (-15°C). You can precisely set the desired temperature via an operation panel.


  • Rapid Cooling in 25 Minutes: The integrated compressor rapidly cools the interior, reaching its target temperature (e.g., 86±32°F / 30±0°C to 5°F / -15°C) in just 25 minutes. This quick performance ensures your items are chilled without delay.


  • Generous 22L (23qt) Capacity: Despite its portable backpack design, the Sofichill boasts a spacious 22-liter (23-quart) interior. This ample space can accommodate approximately 12 cans plus 6 bottles, or enough food and drinks for a weekend trip, maximizing usable storage since no ice is required.


  • Lightweight & Portable Backpack Design: Weighing around 6.3 kg (13.2 lbs), including the compressor, Sofichill is significantly lighter than many traditional coolers of similar capacity. Its soft-sided construction and ergonomic backpack straps make it comfortable and easy to carry on your back, freeing your hands for other gear.

  • Durable & Leakproof Construction: The cooler features a triple-layer soft insulation system:


    • Outer Layer (TPU 840D): Durable, waterproof, and abrasion-resistant for robust outdoor protection.

    • Middle Layer (NBR 25mm): High-density insulation (25mm thick) minimizes heat transfer for extended temperature retention.

    • Inner Layer (TPU 1mm): Leakproof, food-safe, and easy to clean.

    • An Airtight Sealed Zipper (TIZIP) and Cold Lock Press Lid further enhance insulation and ensure 100% leakproof performance.

  • Versatile Power Options: Sofichill offers multiple ways to stay powered:


    • AC Power: Connects to standard wall outlets (110V/220V) for pre-cooling or use at home/campsite.


    • Car Charger: Plugs into your vehicle's cigarette lighter (12V/24V DC) for cooling on the go.


    • Portable Power Bank: Compatible with the optional BeeCell 99 (27,000mAh / 99.9Wh) for up to 8+ hours of cord-free cooling, or other DC batteries meeting 12V/24V, 10A specifications.


    • Solar Charging: The optional BeeCell 99 power bank also supports 100W MPPT solar charging for off-grid use.


  • Long-Lasting Cooling: With a powerful external battery like the BeeCell 99, the Sofichill can maintain cold temperatures for over 42 hours, ensuring extended freshness for your food and drinks.

The Idea

  • Concept: To provide outdoor enthusiasts and travelers with a truly portable, high-performance refrigeration solution that eliminates the mess and inconvenience of ice, offering precise temperature control and extended cooling in a comfortable backpack form factor.


  • Inspiration: ChillBee was founded on the principle of diligence and synergy, much like bees, with a mission to deliver superior cooling performance and a seamless user experience. They identified the limitations of traditional coolers – their weight, bulk, reliance on melting ice, and inability to maintain precise temperatures. The Sofichill 22 is born from a desire to address these pain points directly, offering a modern, efficient, and eco-friendly cooling solution that empowers users to enjoy fresh food and cold drinks on any adventure, big or small. It's about combining advanced technology with practical design to enhance the comfort and enjoyment of outdoor living.
