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.

### ⭐⭐⭐⭐⭐ USB to 9v/12v adapter
*by C***1 on December 7, 2025*

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.

### ⭐⭐⭐⭐ Only 12V work
*by A***O on December 22, 2025*

The 12-volt output works well enough for my needs, but the 9-volt output does not work. It's a good thing that I specifically need 12 volts.
