DROK USB to 12v Adapter - 5V to 12V Step Up Converter, Boost Converter Voltage Regulator with 5.5x2.5mm/3.5x1.35mm Ports and 1.2m Cable

Works great

Works great. I use it to power a 9v TP link router with a USB power bank. And it's nice to know i can also use it for 12v if i ever need it.

Works well with powerbank and compatible with the Masterbuilt Gravity 800. Connection won't twist lock in like Masterbuilt supplied cable but will be enough to make connection (bit of electrical tape to be sure). Easy to use, and had six hour smokes no issues, and can move smoker around to suit weather conditions.

Excelente me sirvió de mucho para usar mi router con un power bank

Product quit working after only a couple of days. It is now only outputting 5V and the little block gets quite warm to the touch.

I like how it has an LCD screen that tells you if it's operating at 9 vs 12 volts. I use this to power a camera via a USB to DC power adapter to avoid having to drain the camera's stock batteries. I used to use a battery bank/power bank that had a dedicated DC out, but those are impossible to find these days. This adapter allows me to use regular power banks and step up the voltage to meet the needs of my camera without sacrificing too much power during the conversion. The only thing to note is that this has a hard time working in sub-freezing temperatures. Generally, it works well above 36 degrees Fahrenheit. If you intend to use this in colder temperatures, you may need to cover it with a hand warmer or keep it close to you inside a pocket to prevent the components from freezing.

I was looking for an accurate step-up converter to bring a 5V output from a power bank up to an even 12V. This converter from DROK does step-up the 5V output as I was wanting, but it doesn't convert to an even 12V like I was hoping. The converter says 12 on the LCD panel, but my Fluke meter sees 12.24 VDC. When the switch on the converter. is on 9V, my meter reads 9.26 VDC. I may not be able to use this for my particular application as a result. Luckily, the converter is just a few dollars which makes the loss easier to stomach.

We needed to find the right size to fit in an old Audiovox DVD player so we bought additional connectors. Works great!

Mobil internet modemim powerbanktan çalıştırmak istedim (gerçekten mobil olsun). Bir powerbank 5 volt veriyor ama modeme 12 lazım. Bu dönüştürücü ile yapabildim. Hem de powerbankın USB çıkış bu kablo modeme uygun bir giriş yaptı. Süper! Çok mutlu oldum!! :)

Ho provato il prodotto con un power banck spostando l'nterruttore di cambio voltaggio ma il il display segnava sempre 4,9 V

شغل راوتر 5G شغل كل الممودمات التي تقبل 12v منتج رائع شكرا لك أيها البائع الرائع

What a fantastic product, now I can plug in and charge 9-12v electrical products from a usb port!.

الكابل معاه تحويله علشان يمشي مع غالب الراوتر انصح بهذا المنتج
