We loved this fan, still use it, but miss the rechargeable option. **Q: how is this newer model ($45) different from the older model for $30 more** A: Hello, I'm not sure what the "older" model was, ours was a 10" 12v that we loved.The newer model has Smart Power technology. It chooses which power option is most efficient. It will run on AC, DC, has it's own rechargeable batteries and you can also use and addition D-cell batteries. That is something that is now made too clear when you are shopping for them. It has internal batteries and you can add D batterries, so you have the option of 4 power sources. The fan motor is also improved to run on less power...giving you longer run time. It has a USB port also. It is a good fan. I'd shop around, I paid more for ours, but I see you can get them under $45 now. **Q: Is it 110 or 220 volt** A: The charger indicates an input of 110-240V. The two prongs appear to be for 110 standard wall outlet. So an adapter to 240V could be required. **Q: What is the difference between this model and black and orange model?** A: Thanks for your question. The only difference is the color. ## Frequently Bought Together - O2COOL Treva 10 Inch Smart Power Fan With Built In Rechargeable Batteries and USB Port For Cell Phone Charging - Amazon Basics 12-Pack D Cell Alkaline All-Purpose Batteries, 1.5 Volt, 5-Year Shelf Life - Treva 10-Inch Portable Fan, Powered by Battery and/or AC Adapter - Desk Fan Air Circulating with 2 Cooling Speeds for Personal and Travel Use (Black) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/1463503-o2cool-treva-10-inch-smart-power-fan-with-built-in](https://www.desertcart.jp/products/1463503-o2cool-treva-10-inch-smart-power-fan-with-built-in) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-08-31*
