NOTE: Please remove the protective film before first use
Please peel off the factory protective film first. The film can appear cloudy or scratched. Once removed, the actual screen is perfect.
Your device comes with a factory-applied screen protector. This is not a defect. For the best viewing experience, simply peel it off before using.
Multi-function button operation instructions:
Short press mode button
- The longer button is the on/off button (it is near the USC output port) & The shorter button is the mode button (it is near the type-c output port)
- 1: Press once to switch screens
- 2: Press the switch button three times in succession to reset the battery (mWh) and reset the timing. Clear current group (0.00)
- 3: Press and hold the switch button for 2 seconds to change the accumulated data storage group number (NO.X)
My USB tester screen looks blurry or has scratches right out of the box. Is it defective?
!! Please remove the factory protective film first !! The film can appear cloudy or scratched. Once removed, you will find a crystal-clear, scratch-free screen. If scratches remain after peeling, find us for a replacement.
The display became very dim after a couple of months. What can I do?
This seems to be a quality issue (backlight aging). Test the unit thoroughly within the first two weeks. If it dims, contact for a return/replace.
How do I reset the capacity (mAh) and energy (mWh) for a group?
Quickly press the mode button three times (triple-click). This resets the current group’s data.
My USB-C port doesn’t work at all, but USB-A works. What’s wrong?
First, rule out the PD “no-load” issue. Try different cables and devices. If it still fails, the unit is likely defective – request a replacement.
Why doesn’t the screen turn on when I plug in a Type-C PD charger?
You must connect a phone (or PD load) to the tester’s output port. Many PD chargers won’t output voltage without a device attached.
