Because the BenQ GV10’s USB port can’t power a Chromecast 4, I still had to carry a power bank when traveling, which was inconvenient. After thinking about it for a month, I bought the BenQ QS02.

Compared to other Google TV sticks and boxes, the BenQ QS02 is much more expensive (NT$1,990) and hard to find. I only saw it in stock on MOMO. It’s not the only 1.0A stick on the market, but since BenQ support confirmed that QS02 works with the GV10, I chose it to avoid surprises.

I’m also a long-time BenQ user; both of my monitors are from the BenQ PD series.

So far, I can confirm that the BenQ GV10 can use the QS02 without any additional power. I haven’t tested how long the GV10 itself can run in this setup.

The nice surprise is that it also works on the EPSON EF11/12 without extra power. I had searched for a long time and couldn’t find the USB power specs for EF11/12, but it seems to be at least 1.0A. The photo above is my EF11 in the bedroom, which used to run with a Chromecast 4 that required external power. When traveling with a projector, besides the projector power cable, I always had to manage the streaming stick’s power too. Now I can just plug it in directly.

Lightweight gear makes placement flexible. Now I can watch TV while doing pull-ups. The “screen” is actually my daughter’s diaper pad.

Update

Starting mid-2025, the QS02 began to freeze frequently. It even booted into a strange console screen, and I had to press reset to make it usable. To be safe, I started bringing two TV sticks when traveling. I never got it repaired and eventually it went out of warranty. I honestly didn’t think a device like this would fail.
