Review: Lots of air, very quiet and runs off of car/boat 12VDC - I needed a fan that would run from 12VDC to use in my boat. We have a Church service at the lake during the summer that I enjoy attending, but it can get really hot sitting in the boat tied to the dock for an hour!! I picked this unit especially because it is designed for 8 D cell batteries (12VDC) and not 6 (9VDC). It does not come with a cable for a cigarette lighter, but they are easy to find. Very happy with the amount of air it moves and that it is quiet enough not to be noticed by others. I have also installed the 8 D cell batteries now and useded it for the last two Sundays with only the internal batteries. Don’t know how long they will last but after approx 1 hour each Sunday and being stored in a boat locker (temps in upper 90 degree range) it is still running like new! I am very happy with this purchase and wouldn’t hesitate to buy another. Just make sure it uses 8 and not 6 batteries if you want to plug directly into a car or boat. ;-) Update: Our summer is over and we are back home, but this fan performed flawlessly and was a real life saver during Church at the river! Worked great with a cigarette lighter cable I already had with or without internal batteries, but it definitely stands up better with the weight of the installed batteries ;-). Definitely recommend these O2Cool fans!!! Review: Really circulates well. - Why did you pick this product vs others?: A relative of mine was living with me for a short time. She had one of these. She always told me get one of these battery operated. I thought yeah right. Probably doesn’t work that great. My power went out for 4 hours and very hot outside. Got the fan out. I was surprised how awesome this worked. Granted it takes some big batteries and quite a few but SO worth it. It kept the air cool in kitchen/fam room areas. Therefore-after using the relative’s fan, you know I bought not one, but two. Put the batteries in, perfect! Great circulation. Thank you! ## Features - Dual power sources: AC Adapter (included) or 8-D batteries (not included) - Powerful 2-speed 10-inch blade fan offers quiet cooling - Grille pivots for directional air flow - Treva - An o2cool brand. - Compact folding design makes it great for travel, easy to carry and store and perfect for indoor or outdoor use ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B071W1GBX8 | | Best Sellers Rank | #1,721,022 in Home & Kitchen ( See Top 100 in Home & Kitchen ) #3,593 in Personal Fans | | Blade Length | 10 inches | | Blade Material | Plastic | | Brand | O2COOL | | Brand Name | O2COOL | | Collection Name | Office | | Color | Black | | Connector Type | Standard AC power connector | | Control Method | Touch | | Controller Type | Button Control | | Customer Reviews | 4.5 out of 5 stars 841 Reviews | | Electric Fan Design | Table Fan | | Electric fan design | Table Fan | | Finish Type | Painted | | Included Components | Cord | | Indoor Outdoor Usage | Indoor | | Installation Type | Portable | | Item Dimensions D x W x H | 12"D x 13.5"W x 4"H | | Item Type Name | Fan | | Item Weight | 1.24 kg | | Manufacturer | o2Cool | | Material | Plastic | | Model Name | FD10003A | | Model Number | FD10003A | | Motor Type | Brushed | | Mounting Type | Stand | | Noise Level | 45 db | | Number of Blades | 5 | | Number of Power Levels | 2 | | Number of Speeds | 2 | | Part Number | FD10003A | | Power Source | Battery Powered | | Product Dimensions | 12"D x 13.5"W x 4"H | | Recommended Uses For Product | Indoor, Office, Outdoor, Travel | | Room Type | Office | | Size | 10 inches | | Special Features | Portable | | Speed | 2 rpm | | Style | Traditional Casual | | Switch Type | Push Button | | UPC | 755247174020 | | Unit Count | 1 Count | | Voltage | 120 volts | | Wattage | 50 watts | ## Product Details - **Brand:** O2COOL - **Color:** Black - **Electric fan design:** Table Fan - **Mounting Type:** Stand - **Power Source:** Battery Powered - **Product Dimensions:** 12"D x 13.5"W x 4"H - **Recommended Uses For Product:** Indoor, Office, Outdoor, Travel - **Room Type:** Office - **Special Feature:** Portable - **Style:** Traditional Casual ## Images ![O2COOL Fan 10 inch Battery or Electric Operated Indoor/Outdoor Portable Fan with ac adapter, Tilts 90 Degrees - Image 1](https://m.media-amazon.com/images/I/91N5OWYyKbL.jpg) ![O2COOL Fan 10 inch Battery or Electric Operated Indoor/Outdoor Portable Fan with ac adapter, Tilts 90 Degrees - Image 2](https://m.media-amazon.com/images/I/91tc4KZsbzL.jpg) ![O2COOL Fan 10 inch Battery or Electric Operated Indoor/Outdoor Portable Fan with ac adapter, Tilts 90 Degrees - Image 3](https://m.media-amazon.com/images/I/81vC9yocj5L.jpg) ## Questions & Answers **Q: Is this waterproof enough to be used in a shower window (where it will get splashed)?** A: No.It is a great fan to have when the power goes off. It isnt as powerful as needed but it is better than most I have seen. It does go through a lot of batteries. **Q: what is the trick for getting the batteries to all fit?** A: put the end ones in first, the middle ones last **Q: Does the fan come with the AC adapter** A: No. I do not recommend it. It stopped working after a month. **Q: What is the jack size/style to use a cigarette lighter cord with it?** A: I don't know about the jack size because the 1st time I used this fan the switch stopped working. I don't recommend buying this fan. I couldn't return it because it was past the time I could. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Lots of air, very quiet and runs off of car/boat 12VDC *by P***R on July 17, 2018* I needed a fan that would run from 12VDC to use in my boat.

Lasted a few days with regular overnight use and even left it on one day the entire day.
