Review: works with my projector! - So happy and impressed. I bought a new LED Projector from desertcart https://www.desertcart.com/gp/product/B07JH74N32/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 This is a 12v projector with an internal battery, but the battery only lasts a little more than an hour, not long enough for a full movie. I bought this USB to 12v dc adapter to power the projector rather than using the wall plug. My expectation was that either it would not provide enough amps, or just enough to more slowly drain the projector battery so maybe I could get 90 or 120 minutes out of the projector battery. To my surprise, this usb adapter not only provided enough energy to power the projector, it also topped off the internal battery charge! Far exceeds my expectations! I put a USB voltage checker on the input, it was taking between 1.75-1.95A of 5.06V from my usb external battery (the kind you use to charge a phone) This will make my projector so much more used, as I use it outside on camping and boating trips.
Review: Absolutely works, but you may need real power for 12V devices (sometimes). - Yes, this will produce 12V from your power brick. Will your device work? Maybe. 12V often suggests more power. If you have a small power brick it may not be able to produce the power you need for your device. You may want to consider a power brick that can produce 2 or more amps (2A). There's some math to figuring out how much power you need, but a good 2A power brick will work for many things. There's no free lunch here, 12V devices usually want more power, a tiny power brick won't do that. So, if you have a good strong power brick, this thing will definitely do the trick. It gets a bit warm but has not failed me. A power brick will usually just shut off to protect itself from burning up (a good thing). You'll know if you're using more power than you have if your power brick shuts off every time you plug this in.

### ⭐⭐⭐⭐⭐ works with my projector!
*by Y***M on June 18, 2019*

So happy and impressed.

### ⭐⭐⭐⭐⭐ Works great
*by B***S on November 14, 2019*

These are great, now I can take advantage of the large number of USB power supplies out there for powering 5V stuff. But do note how many amps you need, since most are only rated for 500ma to 1A! At first I had trouble with this, but the gear I was testing it with (which came with a 3A brick when new) needed at least 2A to be happy, and the regular 1A USB power supplies were simply shutting down. I found two rated for 2A, and even one of those didn't always work. That's okay, since I plan to use it with an extension cord that has a pair of USB plugs rated for 3.6A total. As a bonus, it had a velcro strap built in, a rare case when the item is better than pictured. It may just be the particular lot that the seller got, but I'm happy not to have to add one on my own.
