Frequently Asked Questions About Solar Power Banks – FAQs

How quickly can a device be charged via the solar power bank?

If the power bank is fully charged, the maximum current at the USB output decides how quickly a device (e.g. smartphone) can be charged. The manufacturers provide information in the unit of amperes (abbreviation “A”) – eg “current of up to 2.4A”. 
Tip: You should not buy a solar power bank that can supply less than 2 A of electricity!

How long does it take to charge the power bank using solar energy?

The duration of charging via solar energy depends on the capacity of the solar power bank. The greater the amount of energy, the longer it takes to charge.  Depending on the sunlight (summer, winter, time …) it can take between 50 and 100 hours of sun until the device is fully charged. It is therefore easier to charge a solar power bank via the socket, because it is much faster!

Which connectors are the power banks compatible with?

Most manufacturers make sure that they include special connections so that common electronics such as smartphones, cell phones, etc. can also be charged. In almost all cases, this is a normal USB cable or micro USB cable. 
For this reason, the power banks presented here all have an output voltage of 5 volts in order to be compatible with all common USB devices
