Frequently Asked Questions About Energy Storage Power

General Questions

Let’s assume your device’s power consumption is 60W (might be a box fan), and you want to use the T500 to run your device.
540Wh*0.85/60w = Roughly 7.5 hours of working time
Please note the actual power consumption varies based on many factors.

WANROY power stations can be charged with a third-party brand solar panel. The plug size and input voltage you are trying to charge with must match the WANROY’s power station. We can’t recommend other brand products to recharge your WANROY power station. As we can’t guarantee the safety and quality of those products or provide after-sale service for them. It is highly recommended that you purchase the matching WANROY solar panel(s) for your WANROY T500.

Yes, although the charging efficiency will be low causing prolonged charging time.

  1. It cannot. You would need to use the same parameters of solar panels to charge the power station.
  2.  The 28W solar panel voltage is 4V, and the 60W solar panel voltage is 18V. Mixing the two would cause the high voltage to flow back to the low voltage, which will damage the circuit and cause damage to the power station.
  1. We recommend keeping the battery power above 20% when using or storing the power station regularly.
  2. Please store the product in a room temperature place and avoid humid environment. In order to prolong the battery life, please charge the battery grids to fifth gird if the equipment was not be used over 3 months.
