Best Practices

  • It is important to note Internet enabled smartphones require a lot of POWER! Much more than traditional cell phones.
  • It is recommended to charge a smartphone when the ZEUS PowerBank is at full capacity.
  • Set aside a few hours to recharge the ZEUS PowerBank to full capacity first, before using it to charge a smartphone.
  • It is recommended a smartphone is left “OFF” while charging it on the ZEUS PowerBank. The PowerBank will charge a smartphone at a more efficient rate when the phone is turned off.
  • If a user tries to charge a smartphone on the ZEUS PowerBank when both the PowerBank and phone are extremely low on battery, this will likely cause the ZEUS PowerBank to immediately shut down. Make sure the PowerBank is recharged to full capacity first.
  • Recharging the ZEUS PowerBank with a smartphone wall adapter IS possible. It has been tested using the Samsung 1Ah wall adapter and found to successfully charge the device.
