Ok not entirely sure who this is on, but the AA drill will recharge from a TE Flux Capacitor that is in my hotbar but the AA magnet does not. I provided the RedstoneFlux version just in case that is helpful.

Actually Additions: 1.12-r115
Thermal Expansion: 1.12-5.3.2.10
Redstone Flux: 1.12-2.0.1.2

This is on Thermal's end, last I checked they were not properly looking for the Forge Energy item capability. It also has the effect that the Energetic Infuser will not charge AA (or any FE-based) Items.

Paging @KingLemming about this

I've mentioned this to KL before about the infuser, but I hadn't mentioned the Flux Capacitor, as I am actually using one right now with no issues... (in atc)

@Shadows-of-Fire - you are only somewhat correct there. The code is in the infuser and we ARE supporting Forge Energy.

The issue was that the Infuser didn't accept non-RF stuff in the GUI. It could be inserted via automation though. But that's been fixed.

I think the issue here may be simply that the capacitor doesn't charge things "in the hotbar," only held and worn items, and it sounds like the item isn't being held.

Closing this for now as it seems like user error.
