Review: Super handy USB to 9 V power converter — keeps my TP-Link router running from a power bank - I picked up this DROK USB to 9 V/12 V step-up converter to power my TP-Link router (which requires a 9 V input) directly from a power bank when the grid goes down — and it works exactly as I hoped. Instead of scrambling for a wall outlet during power outages, I simply plug the USB end into my power bank, switch the converter to 9 V, and my router stays online. It’s been a reliable backup solution that keeps my Wi-Fi active when I need it most. ✔ What I liked • Reliable backup power: The converter consistently delivers stable 9 V output from a standard 5 V USB source, so my router stays connected through outages. This has given me peace of mind knowing my network won’t drop unexpectedly. • Easy plug-and-play setup: Just plug the USB end into a power bank, flip the converter to 9 V, and connect it to the router’s DC input. No additional adapters or complicated steps required — it works right away. • Clear voltage indicator: The built-in LED display shows the selected output voltage clearly, so I always know I’m supplying the correct power. • Compact and portable: It’s lightweight and small enough to stash with my emergency gear or travel kit, and the cable length is good for routing without strain. ⚠ What to know • The output tops out around 1 A at 9 V, so it’s important to make sure your device’s power draw stays within that range — in my case, the TP-Link router runs perfectly well on this. • Best suited as a backup or temporary power solution (e.g., during outages or when on the go), rather than a full-time substitute for a dedicated power supply. ⭐ Final Verdict This USB-boost converter is a simple, effective way to run a 9 V device from a USB power source like a power bank. It gave me exactly the backup power solution I needed to keep my router online during outages, and the easy setup with a clear voltage display makes it very user-friendly. ✔ Highly recommended if you want a reliable backup power option for routers and other small 9 V devices.

### ⭐⭐⭐⭐ Works great for my use case.

First off, I hate bright LEDs on power supplies and USB cables. The green led of this one isn't as bad some blue LEDs but it's still too bright. One star off for the bright LED. I'm using this to power a HDHomeRun Flex 4 tuner. It generally hovers around 12 volts and 0.8 amps. Tried a couple of 1 amp supplies and the tuner just didn't like them and I wouldn't get some of my local channels. Was looking for a higher amp USB power supply and couldn't find much out there. Guess 12v1amp is pushing the USB spec. Thankfully this one delivers 1.2 amps and HDHR tuner is fine with it. I'm using an Anker multiport USB power supply to power a RaspberryPi, USB antenna booster and the HDHR. The USB supply is designed for 3+ amps out each port at same time. So the DROK step up converter is doing fine. If your trying to power it with a cheap phone charger, your results may not be as good. My goal was to mount the antenna stuff, Pi and hard drive on small board and hand it on a wall in the garage. Not have it be an eye sore and still be compact. The DROK supply help to not have a wallwart blocking a power outlet.
