Hallo!
I have a question.
I built a power supply without batteries.
Therefore I downloaded the 3D-file for the Batterie pack and fixed 2 contacts and a USB-A link into it.
The energy comes from a usual Mobile charger (5V).
I tried several chargers (0,2A; 0,5A; 1A; 2A), even a cheap solar power bank! For normal use 0,2A are enough, even the card reader worked fine! But when I try to use the wand, even 2A are to less! Although the wand was detected in Cat 2, it does not read!
As soon as I insert the serial battery pack the wand worked fine and read the lines.
Is there anyone who can explain why the wand doesn't work with my self made powersupply? How high must (may) the Ampere be for the wand? I don't want to grill the motherboard with a too high stream! Is there a sensor in the wand or in the 41 that distinguish between my powersupply an the battery pack?
Thanks for help!
Andreas
