    o2 Cool Fans

  • What power sources Does this fan USE?: The Smart Power fan selects the lowest cost energy option. It selects the AC or DC adapter first, the rechargeable batteries second and the 8-D alkaline batteries third.

    How long does it take to charge the fan?: The charging time is based on the level of charge left in the batteries and whether or not the fan is in use during the charge cycle. We recommend that you monitor the indicator lights to determine when the unit is fully charged.

    How do I charge the fan?: Switch fan to \xF1OFF\xEE, connect the AC or car adapter to the fan, then plug the adapter into an electrical outlet or the car adapter into the car power outlet. Slide switch to one of these positions: HIGH, LOW, or STOP. It\xCDs necessary to begin the sequence in the OFF position to reset the Smart Power\xAC controller.

    What should I do before I store my fan?: Prior to storage, fully charge the rechargeable batteries. Store the fan with all plugs removed and the slide switch in the OFF position.

    How long will the rechargeable batteries last?: The rechargeable batteries can operate the fan up to 5 hours under typical use and can be re-charged up to 500 times.

    Can you recharge the batteries with a car adapter?: Yes. It takes the same amount of time to charge as it would using the wall adapter.

    The charge light won\xCDt stop blinking, and it HAS been over 24 hours.: Turn the fan on to see if it is working. If so, there might have been a malfunction in the light switch. If the fan still does not work, the rechargeable batteries have exhausted their useful life and the fan will need to be operated with other power sources.

    Can rechargeable batteries be replaced?: No. You cannot replace the rechargeable batteries built into the fan.

    I cannot see the rechargeable batteries. Where are they?: You cannot see the rechargeable batteries because they are built in.

    How do I dispose of the rechargeable batteries?: The batteries can be taken in a recycling station found at most electronic retailers.

    We have two O2 Cool 20" fans we got about 15 years ago. They've gone with us, or with our grandson, to music festivals in four states, and have increased our comfort level for years!

    The fans are great. We use them on our boat when we are away from the dock. Just a little breeze makes life so much nicer.

    I looked at many sources for a small, portable fan that would run on batteries. Our area had a power outage recently and i was without a fan for two days... misery! I found this one which not only runs on D-cell batteries but has its own internal battery and can be re-charged. Excellent product.

    Bought this for outdoor archery tournaments! We compete in the heat of the summer, and I saw someone had one of these, thought it was a great idea...so I bought one, and really it has proven to be really good. Overnight charge will do the whole day! Highly recommend this product!
    • Wireless...has a built in rechargeable battery! Impressive air circulation.
