suggest opening this link and reading the test report. Further questions will then become superfluous. Greetings
Hello,
I'm not sure if it's a good idea to use the battery as a power source or not, but I'm not sure if it's a good idea to use the battery as a power source or not. I'm not sure if it's a good idea to use the battery as a power source or not.
Hello Michaela
It depends on the power consumption of your device. This power bank supplies a maximum of 18W. I assume your Dell or Lenovo notebooks need more than this 18W. But if they can manage with so little power, then it might work. It doesn't work with my Levono because it needs 65W. You can usually find the required wattage on the original transformer of the laptop in question. Hope this helps.
Both work with the micro USB, i.e. charging the powerbank and supplying external devices with power. By the way, this is a very recommendable powerbank.
Here is all the information: Input: micro USB: DC 5 V/ max. 2,000 mA; USB type C: DC 5 V/ 2,400 mA, 9 V/ 2,000 mA (PD 18W); Lightning: DC 5 V/ 1,500 mA | output: USB 2x: DC 5 V/ 3,000 mA, 9 V/ 2,000 mA, 12 V/ 1,500; type C: PD 5 V/ 2,400 mA, 9 V/ 2,000 mA, PD 1,500 mA
almost always cable included, no charging plug.
device supports fast charging function. which fast charging plug exactly supports this is not described. i suspect something with 15, 18 or 20 watt, the specification of the fast charging function is important.
