How to Reset Your Jackery Explorer 300 Plus
Here are several methods to reset your Jackery Explorer 300 Plus, starting with the simplest and progressing to more advanced solutions.
Method 1: Soft Reset (Power Cycle)
This is the first thing to try for most issues. It’s a quick and easy way to resolve temporary glitches.
Diagnosing the Issue
This method is ideal for minor issues like a frozen screen or unresponsive buttons.
Fix Steps
- Turn off the Jackery Explorer 300 Plus by pressing and holding the power button for 2-3 seconds until the screen goes dark.
- Disconnect all cables and devices connected to the unit (AC, DC, USB).
- Wait for 30 seconds. This allows any residual power to dissipate.
- Press the power button again to turn the unit back on.
Testing
Check if the issue is resolved. Test the AC outlets, USB ports, and DC outputs to ensure they are functioning correctly.
Method 2: Long Press Reset
This method is similar to a soft reset but involves a longer press of the power button.
Diagnosing the Issue
Use this method if the soft reset doesn’t work or if the unit is experiencing more persistent issues.
Fix Steps
- Ensure the Jackery Explorer 300 Plus is powered on.
- Press and hold the power button for 15-20 seconds. The screen may flicker or briefly turn off. Continue holding the button.
- Release the power button. The unit should restart.
Testing
Verify that the unit powers on and functions correctly. Test all outputs.
Method 3: Firmware Update (If Applicable)
If a firmware update is available, it might address underlying software issues.
Diagnosing the Issue
If the unit is functioning but experiencing intermittent problems or if the Jackery app indicates a firmware update is available, proceed with this method.
Fix Steps
- Download the Jackery app on your smartphone (available for iOS and Android).
- Connect your Jackery Explorer 300 Plus to a stable Wi-Fi network.
- Open the Jackery app and follow the on-screen instructions to check for and install any available firmware updates. Important: Do not power off the unit during the update process.
- Once the update is complete, the unit will restart automatically.
Testing
Test all functions of the Explorer 300 Plus to confirm the update has resolved the issue.
Prevention Tips and Maintenance Advice
Preventative maintenance can significantly reduce the likelihood of issues with your Jackery Explorer 300 Plus.
- Store Properly: Store the unit in a cool, dry place, away from direct sunlight and extreme temperatures.
- Regular Charging: Avoid letting the battery remain at 0% for extended periods. Charge it to around 40-60% for long-term storage.

Pro Tips

- Reset While Charging: If the unit won’t power on, try performing a long press reset while it’s connected to a power source.
- Battery Calibration: While not officially supported, letting the battery fully discharge (until the unit shuts off) and then fully recharge it can sometimes help recalibrate the battery meter.
- Avoid Extreme Temperatures: Operating or storing the unit in extreme temperatures can damage the battery and affect performance.
- Clean Contacts: Periodically clean the charging and output ports with a dry, lint-free cloth.
