I installed it in this box https://www.amazon.com/gp/product/B00E6MZ832/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1 and use it to power some waterproof string lights near my pool. The lights pretty much use the max amperage the unit can provide, and it remains cool to the touch. **Q: My unit started buzzing. Anyone else have that issue?** A: Something is probably just vibrating in the unit. Remove the top, fire it up and watch to see what component is vibrating. Probably a capacitor or an inductor. Then power it down and add some hot glue to that component. Should fix it. This is all assuming you are outside your return time, of course. **Q: Input polarity? I am noob so please tell me if using with type f socket i have to always make sure that L&N inputs match the output of wall plug?** A: GreetingsFor the input of the F-type socket, the L & N of the AC line of the power supply is to maintain the connection of the corresponding hole, and do not reverse, so that the power supply can work more stably. **Q: How to power a 8 raspberry pi 4 cluster? Need a terminal block or do without and daisy chain? Or does each each positive negative need to feed to sour** A: They can be connected in parallel as long as you use wire gauge heavy enough to carry the amperage......which won't be much. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by C***N on November 7, 2018* ### ⭐⭐⭐⭐⭐ Review *by S***E on January 5, 2019* ### ⭐⭐⭐ Review *by M***E on August 11, 2019* --- ## 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.tn/products/88388977-letour-5v-power-supply-40a-ac-110v-220v-converter-dc](https://www.desertcart.tn/products/88388977-letour-5v-power-supply-40a-ac-110v-220v-converter-dc) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-20*
