Wh = watt hours is the measure for electrical energy that is stored in the Power Bank.

Did you know?

There is no need to fully charge and discharge
(full cycle) your Power Bank. It is possible to add 10%, 20% or 30% anytime you want. Partial cycles can even prolong the lifetime of your Lithium-Ion battery.

How to Extend your Power Bank’s Life

  • DO consider temperatures
    The Power Bank should not be charged at temperatures of under 5 degrees and should not be discharged at temperatures over 40 degrees.
  • DO disconnect the charger of your Power Bank as soon as it’s fully charged
    This is also useful when charging your device.
  • DO charge your Power Bank even if you don’t use it
    To keep the Power Bank in good working condition, you should charge it at least every three months.
  • DO avoid to fully charge your Power Bank
    For best performance and longer lifetime do charge your Power Bank only up to 80% and discharge only up to 20%. Most Power Banks have a charging status indication.
  • DO NOT drop the Power Bank
    The Power Bank contains a circuit board and other fragile components inside. Always make sure to handle it carefully. Don't drop or throw it.
  • DO NOT expose the Power Bank to extreme temperatures
    Batteries prefer temperatures between 5 and 25 degrees. The more you deviate from that comfort zone, the bigger are the irretrievable capacity losses that might result. This also includes not covering the Power Bank with a blanket or clothes.
  • DO NOT keep your Power Bank in pocket or bag with metal objects
    It is always best to be careful and make sure they are never placed in a position where metal objects could short the output.
  • DO NOT charge your Power Bank and your device at the same time
    It affects the battery health of Power Banks due to excessive heat production in both kinds of charging.

12,000 ÷ 2,000 × 0.7 = 4,2*

*amount may vary depending on different influencing factors:

  • Usually the accu of your device is not completey discharged (best case ~ 20%).
  • Usually you never completely charge your device (best case ~ 80%).
  • The capacity of the Power Bank (and your device) slightly decreases over time due to the Lithium-Ion accu.
  • If you use your device during the charging process the provided power is being consumed simultaneously.
