The USB charging cable is suitable for charging the nachfolger high-performance electric pump for the next use. The USB charger has a small LED that lights up red when charging. The small red light will turn off (or turn green) when the pump is fully charged.
The 240V power pack should have an output power of at least 1 Ampere hour (Ah), otherwise the charging process will take a long time or the pump will not charge at all. If the HyFive USB charging cable is used in the car or on the plane, make sure that there is always more than 1Ah, otherwise the consequences mentioned can occur.
