Have you put an accumulator into it? The backpack's just the frame, you need to install an accumulator via the workbench for it to function.

I can reproduce it in 1.21

I have the same problem in 1.21.1
I placed an accumulator inside of the backpack, and it does not charge.
I need to charge the accumulator outside and then add it to the backpack.
