iGreely USB Voltage Step Up Converter - DC 5V to 12V, 3ft Cable with DC Jack 5.5 x 2.5mm or 5.5 x 2.1mm

So I tend to try to prepare for the worst case scenario and since I have some massive power banks. I figured if I could power my modem router in a power outage without using my generator this would be perfect. I purchased a asus router that I just keep around to connect to my phone mobile data to run my essentials during a power internet outage. Usb tethering making for a much more reliable service then just a Hotspot. Helping with streaming and keeping everyone from going crazy on me. If this is your way of thinking this will work for the said application.

These cords work great for the monitor for my Bach up camera. The supplier provided the link to order them easily. If you need this cable, I would recommend purchasing these cables.

Perfecto

This device is good for some 12V wifi routers, 12V bluetooth speakers and perhaps 12V Monitors for desktop and gaming, it also works on desktop disc drives if you have an adapter for it, depending on what the device whattege rating is, this device may not work if the 12V device you connect it to requiers higher whattege, make sure you test it out on the 12V devices that this item may work on, it doesnt work for all 12V devices.

This adapter cable is just great! I needed to power a Shure wireless microphone receiver (needs 12 vdc) from a device that has a USB port delivering 5 vdc at 2.0A. This port was intended to charge a mobile phone or tablet. This inexpensive adapter cable let me connect the receiver right to the USB port. The coax connector was an exact for for the powered device. I no longer have to carry an AC adapter for the wirless microphone kit.

Esto convertidor de voltaje USB es tal y como está en la foto, la verdad es que funcionó correctamente

This USB cable is weak near the connector. It breaks easily and stops working

I used it to connect a Flame Boss 400 blower which requires 12v power, to a Milwaukee top off power inverter with 5v output from its USB A port. I let it run for a few hours and it ran steady with no issues from the cable. The real test will come when I use it for an actual longer cook on my grill and I’ll update then.

Prodotto di buona fattura, usato per accendere una striscia led di 50 centimetri dietro il televisore utilizzando la porta USB dello stesso, Funziona egregiamente oramai da qualche mese. Ho dato quattro stelle perché le specifiche tecniche sono carenti, ovvero non è scritto quanti milliampere supporta come carico, specifica tecnica molto importante.

ممتاز لتشغيل الراوتر والرسيفر وغيره

worked well - now run an outside controller off a USB (PD) battery instead of Mains adapter - much better.

Very good product, it did its job

I work with network equipment and often have to use small Netgear switches or media converters in racks or whilst moving about. There are often no mains sockets available. This lets me power the switch or media converter from my laptop, or even a convenient USB port on the equipment itself, like on most Cisco gear. You do need to check it won't pull too much current, but it's fine for most reasonable use cases. Robust enough as well. Maybe my only complaint is the electronics are all in the plug, which is quite deep. This sometimes means you can plug it or leave it plugged in with limited space. If it was in a blob on the middle of the cable, you could do this. I tried another type of this cable before and it was not nearly as robust or stable.
