I have saved approximately 20% on my electric bill over the last 6 months, my home is total electric. I gave away 5 of these to family and friends, they're all impressed with the savings. By the way I was an electronics supervisor at RCA for over 10 years and I believe you meant UL approved, not OSHA. **Q: How come reviews of this product outside of Amazon claim that this item does not save electricity, but in fact uses electricity and is fraudulent?** A: I got them and been using them but it actually say it will around 3 months 2 see the savings so I'm waiting **Q: The directions mention ac, ovens, refrigerators but those have dedicated circuits. how can you plut it into your oven 220v circuit?** A: I threw mine away. IT DOESN'T WORK. **Q: IS this a waste of money scam???** A: It saved me money ## Customer Reviews ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars THIS REALLY WORKS! *by C***C on Reviewed in the United States on June 30, 2021* I was skeptical about this product, but I needed to do something about my electric bill. For the longest time, my power bill had been above $200 every month. I have a 1200 sq foot home, and have not used the AC or heater, yet my power bill had been just ridiculous. I live alone and I use electricity pretty minimally to moderately I would think (TV, phone charging and your normal fridge, washer/dryer). I even thought someone was secretly siphoning electricity from my house, but it’s not the case.Then I bought this product in March. First month, I didn’t see any big difference. From $265 to $195, ehhh ok, a little bit but I was not impressed. Second month when I started seeing a difference. See pictures attached. My power bill speaks for itself. The other helpful habit I’ve added to the savings is unplug unused appliances except my tv, fridge/alarm system, dryer/washer - which in itself is not significant.Last bill was $118. From $250+ to $118, it’s pretty significant.So yes, I think this product has helped me with my power bill. Give it some time - it worked really well for me. It may just work for you, too. ### ⭐ 1.0 out of 5 stars Scam *by A***R on Reviewed in the United States on March 23, 2023* Waste of money. I bought two. One, i guess quit working after a few weeks. The LED light went out.The other came apart in my hand when i removed it from a receptacle. I saw no change at all in my electric bill ### ⭐⭐⭐⭐ 4.0 out of 5 stars Fragile *by T***R on Reviewed in the United States on September 20, 2021* Definitely made and difference for the better but on of pair's plug prong pulled right out of it. --- ## 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.com.cy/products/274445589-power-save-90v-250v-30kw-electricity-saving-box-energy-saver](https://www.desertcart.com.cy/products/274445589-power-save-90v-250v-30kw-electricity-saving-box-energy-saver) --- *Product available on Desertcart Cyprus* *Store origin: CY* *Last updated: 2026-04-25*
