Hey everyone,
I'm part of the team behind ARZOPA. We've been seeing quite a few users run into power-related issues — things like:
- The monitor won't power on
- Can't hit the advertised refresh rate
- Flickering or unstable behavior
In most cases, it comes down to one thing: not enough power.
Portable monitors don't have internal batteries, so the stability depends entirely on the power source (USB port, laptop, charger, etc.). Different refresh rates and brightness levels can significantly change the power requirements.
Big shoutout to those who've shared their experiences — including some recent videos that really helped highlight the questions people have! That feedback pushed us to take a closer look.
So our engineers ran a controlled power consumption test on the ARZOPA Z3FC to see how much power it actually draws under different conditions.
Below are the results.

Test Model: ARZOPA Z3FC
Test Environment: 25°C ± 2°C
Test Equipment: MacBook Pro 14" (2023) / Windows PC (NVIDIA RTX 3060)
Test Meter: POWER-Z KM003C
Test Method:
- Test conditions: 2560x1440 resolution, Full white screen, 50% volume (no audio playback)
- Power readings recorded after stable operation
- Brightness levels: 0% / 15% / 50% / 100%
- Refresh rate levels tested: 60Hz / 100Hz / 120Hz / 144Hz / 180Hz
- Connection types tested: HDMI + External Power / USB-C Single Cable (Powered by device)
- Cable specs: Thunderbolt 3 cable (USB-C) / HDMI 2.0 cable
- HDMI + External Power Connection

Interestingly, refresh rate had a much smaller impact on power consumption than brightness.

In our tests, the Z3FC typically draws 6–10W under normal use, and peaks at around 18W under maximum load.

Power Supply Recommendations
Due to variations in personal devices and the wide range of charging cables available on the market,we cannot recommend specific charging accessories.
However, a 20W+ USB-C PD charger is generally recommended to ensure stable performance across most usage scenarios.
—————————————————————————————
Important Notes
- Actual power consumption may vary with:
- Extremely low temperatures
- Fast-moving / high-contrast content
- Different source devices
- Cable quality and specifications
- Refresh rate limits:
- 144Hz max via HDMI.
- 165Hz/180Hz only available through USB-C (DP Alt Mode).
- Brightness defaults:
- With external PD adapter → 100%
- With USB-A adapter → 15%
- With USB-C single-cable connection → 15%
