Helpful Ordering & Product Information, Product Selection & Ordering Information

• Material Selection Guide: We offer several engineering-grade material options to match different environments and performance requirements. If you're unsure which material to choose, ASA or PET-GF will be an excellent choice for most customers and provide a great balance of strength, heat resistance, durability, and outdoor performance.
  • For more demanding or specialized applications, we offer additional engineering-grade polymers with enhanced mechanical, temperature, impact, or flame-retardant properties.
  • Need help choosing? Check out our YouTube Material Selection Guide, where we explain the different polymers we offer and help you determine which material best fits your application.
• Need help choosing between the PowerMount Plus or PowerMount Pro of the GoPro Mission 1 M1X and 9Thirteen coolers? Watch our Cooler Selection video to find the best option for your camera and application.?
• CAMCooLER fans are IP-68 rated custom manufactured to our specifications rather than standard off-the-shelf cooling fans.
  • Fans installed in products manufactured after February 2026 are IP68-rated for dust and water resistance, unless otherwise stated.
  • Fans operate at approximately 5,000 RPM with standard USB power or can be adjusted from 2,500–7,000 RPM with our optional speed controller, allowing users to balance cooling performance, airflow, and fan noise for outdoor, indoor, or studio applications.
  • For applications requiring additional fire-safety performance, we also offer UL 94 V-0 flame-retardant fan options.
• Expedited Order Processing, if selected, only prioritizes order handling, faster picking, packing, and handoff to the shipping carrier. It does NOT upgrade or change the shipping method or service. If faster delivery is required, a premium shipping service must be selected at checkout.

  For in-stock items, your order will be prioritized and processed ahead of all other orders, ensuring faster picking, packing, and handoff to the shipping carrier. Orders are typically shipped within one business day, or the same day if placed early enough.

  Saturday, Sunday, and US federal holidays are not included in this timeframe. If we do not hand off your package to the carrier within three business days of your order being submitted, the expedited processing fee will be refunded.

• Run Time: A 10,000mAh 45W fast-charging power bank typically provides about 5.5 to 6 hours of combined camera recording and active cooling runtime in our real-world setups.

  For longer tournaments, doubleheaders, or all-day recording, we recommend stepping up to a 20,000–30,000mAh power bank for extended runtime and extra headroom. We recommend the UGREEN Nexode 25000mAh Power Bank.

• Now offering FedEx/UPS Overnight, or 2 day shipping options for domestic orders for an additional fee. (fulfillment typically 1 to 2 days) Free ground shipping still applies to all domestic orders over $40.
• Backordered item? No worries—we’ll manufacture and ship it promptly based on your order date. Don’t wait for available inventory, as backorders are fulfilled in the order they’re received. Some products may never appear as 'in stock' because they ship immediately after production, with no extra inventory available due to high demand. Items marked 'out of stock' and not available for backorder have either been discontinued or currently have an uncertain delivery timeline.
• No USB wall chargers included: Our coolers don’t come with a wall USB charger since most people use a battery pack instead. The great news is that those old USB chargers you’ve got tucked away—too weak for today’s smartphones—work perfectly with our coolers because they need so little power.
• Anker Power Banks require "Trickle Charging Mode" to work with our cooling fans. Currently, there are no other known issues with power banks. We recommend the UGREEN Nexode 25000mAh Power Bank. It also fits perfectly in our indestructible battery holder.
• Add Speed Controller: https://camcooler.com/product/usb-cooling-fan-governor-zk-ufs/   The USB Speed Controller is NOT waterproof.

• All CAMCooLER cooler cases are manufactured using high-quality, engineering-grade polymers selected for strength, heat resistance, durability, and demanding real-world use. We do not use hobby-grade plastics in our cooler cases. When comparing products, look for manufacturers that clearly disclose the materials they use. If a manufacturer doesn't identify the polymer, it's difficult to evaluate its actual mechanical and thermal performance. CAMCooLER believes customers should know exactly what they're buying.

• 11/3/2023 Update: Introducing our latest innovation: an adjustable rpm fan designed to cater to your specific cooling needs. Whether you find yourself in a cozy studio environment or basking under the scorching sun at your next event, this fan has got you covered. With the ability to lower the fan speed, we have successfully minimized the noise output, ensuring a tranquil atmosphere for your studio endeavors while still helping to prevent your Action 4 camera from overheating.
  Equipped with an included user-friendly controller, our variable fan offers a wide range of rpm options, ranging from a gentle 2500 rpm to an impressive 7000 rpm. While it is highly improbable that you will ever require speeds exceeding 5000 RPMs, we believe in providing you with the flexibility to adjust the output according to your preferences without compromising the electrical integrity of the fan. Embrace the power of choice and experience the perfect balance between cooling efficiency and noise reduction with our variable rpm fan. If the variable controller is unnecessary for every event, set it aside and connect it directly to the USB plug for a constant 5000 rpm fan.
