Please indicate which PowerBank complies with the new 3C safety certification (China Compulsory Certification). Please also add a filter for this. Stricter regulations now apply to the carriage of power banks on certain flights. This was triggered by safety problems.

I am looking for a suitable power bank to power a sensor (Sensirion Minion) via a USB connection. Unfortunately, most powerbanks have an automatic standby mode. However, since the sensor has almost no consumption, it automatically switches off the power supply again after a short time. => Is there a powerbank/battery that does NOT go into standby mode and continuously feeds the sensor?

Why are there hardly any power supply units with cables? So you can't charge anything directly and always have to look for cables that also correspond to the power category ...

When will the powerbank be back or will it no longer be available?

In general, mAh makes little sense, without V you ultimately don't know what power the power bank can deliver.....
