FARSENSE USB DC 5V to 12V Step Up Power Cable(3FT),USB C to DC 12V Adapter with DC Jack 5.5 x 2.5mm(Compatible with 5.5 x 2.1) and 3.5 x 1.35mm, Boost Converter Supports Voltage Display

Works! Nice.

I was quite happy to find that this small unit not only lives up to its specs (12 volts @ 1 amp) but also displays this on a digital display. It will start to drop just a bit once it hits around 980 mA and it Will drop out if you exceed 1 amp by even 100 mA. Also note that if yo run it close to the maximum, it will run quite warm. This didn't seem to effect its performance though. I was using it to power a portable DVD player. It ran needing about 670 mA to 800 mA depending on whether the volume was low or high and if I was using a Fire stick or not. It was pulling about 1.3 to 1.7 amps from the USB source which in this case was a battery bank. In my case, the included adapter didn't fit my player, but I didn't expect it to. You can find adapters on Amazon. Just be aware that this units polarity is the more common tip +. If you have a tip - device, you will need to get an adapter to reverse the polarity or cut the cable and do it yourself which will void the warranty. This small converter does work very well for extended periods of time and I've been very happy with it. Just be aware that it will not exceed 1 amp. It also won't exceed a 2.4 amp draw from your source. So, it's also quite efficient. At this price you really can't go wrong.

After 1 week and working great. I use it to power a 12V fan for my mini pc via usb.

Después de un tiempo falla y se calienta, pero cumple su propósito

Works great for what I needed it for. I wanted to replace my DC plug for my gun safe led lights as the original plug was bulky and took up too much space on the built in power strip so I wanted something that took up less space and came across this and it worked out perfectly. Quality seems good and is able to power up the led lights in my safe.

Bought two of these and they worked perfectly. Stable voltage and right on the money. Bonus adapters for flexible use. Other I bought for a dollar or two less failed at the outset. These were a bargain.

claims to have a 3.5mm DC adapter as well as shown in photos. does not

Works perfectly! We bought it for our car camera for our kids and it was exactly what we needed! Super easy set up, it literally just pulled right it to the car and then into the jack for the camera. It’s never hot when we touch it unless we’ve just gotten into the car, but we do live in Texas where it’s already in the high 90s. Definitely worth the price!

Super achat fonctionne parfaitement

Amazing! It works well with Cudy 4G router. Now I can power up my Cudy 4G router from a USB power bank! It runs Cudy router for 16 hrs. I don't need to worry about internet outage anymore!

Garbage.
