I think this has been a bad buy. I have one of the smaller ones and that is good batteries are long lasting (9v) and I have had the unit for about 4 years changing the batteries about 3 times a year and it is still going strong **Q: Will it be effective for Squirells? Tell me if you know it please.** A: No, squirrels seem totally unphazed by these, even the ones with flashing lights. You need proper squirrel traps, which are humane if used correctly. **Q: What adapter does it use ??** A: The adapter for this product can be purchased from the company that sells it. The recommended adapter is on the instruction leaflet. **Q: Can I use rechargeable batteries in this as others run down very fast?** A: Not sure to be honest. I keep mine constantly plugged with the use of the power cable to an outside plug socket. I used to use non rechargable batteries but they drain very quickly. But once plugged in, it works perfectly fine. Worked well for a few years now. ## Frequently Bought Together - Defenders STV620 Mega-Sonic Cat and Dog Repeller, Mains and Battery Powered Garden Pest Repeller - The Big Cheese 9v Universal Mains Adapter and Extension Cable Kit for Mega-Sonic Cat Repeller and Mega-Sonic Fox Repeller --- ## 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.us/products/50423870-defenders-stv620-mega-sonic-cat-and-dog-repeller-mains-battery](https://www.desertcart.us/products/50423870-defenders-stv620-mega-sonic-cat-and-dog-repeller-mains-battery) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-14*
