CECCCROHS 120 Review: it's a "wall wart" does not match picture. - I was specifically looking for a power supply that wasn't a wall wart since the 16 volt units are very fat and take up too much space on an extension cord. I bought this unit because the picture in the listing shows the transformer in-line with the power cord away from the receptacle which is exactly what I was looking for. Very disappointed when it showed up, the item in the picture is NOT what I received. See my picture, it's the same as what I already have. So it was a time waster, shopping the many transformers, finally selecting one, waiting for it to be delivered, and now I have to go through the hassle of returning it and starting over. People lead busy lives and this false advertising wasted a lot of my time. Buyer beware. Review: Ignore the first 2 pictures in the advertisement - i received the item in picture 3 - The only reason I purchased this item from other similar items is that the main picture showed a power supply with a cable to the outlet rather than a "wall wart" style. I got the wall wart (you see it in the 3rd and 4th pictures actually) which doesn't fit in my already crowded power outlet board. Seller should remove the main picture and second picture which are misleading. ## Features - AC Input Voltage: 110V-117V-120VAC 60Hz or 220V-230V-240VAC 50Hz Suitable Input Voltage For Your Country/Area.

I plugged this adapter into a mic pre amp and obviously it was too powerful and it fried my pre-amp. This is a great adapter as it works fine with my other pre-amp. ## Customer Reviews ### ⭐⭐ it's a "wall wart" does not match picture. *by B***P on October 1, 2022* I was specifically looking for a power supply that wasn't a wall wart since the 16 volt units are very fat and take up too much space on an extension cord.

Powered my Presonus Bluetube perfectly. --- ## 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/6280818-upbright-16v-18v-ac-adapter-compatible-with-presonus-tubepre-microphone](https://www.desertcart.tn/products/6280818-upbright-16v-18v-ac-adapter-compatible-with-presonus-tubepre-microphone) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-11-08*
