I had originally posted the first version of this model based on a ravpower battery that was recommended in a YouTube video as a good companion battery for the Steam Deck.  I made the model and posted it prior to realizing that it would only work as a slow charge battery.  I didn't realize it at the time so I have since pulled that down and updated the model to be based on a fast charge model listed below.  This new holder works the same as the previous one, but this time I've confirmed the battery works as a fast charge.

The link to the battery I purchased is the first one below.  However, I just realized when comparing the packaging to the battery I ordered that the details are different.  In the first link below you will see a 10,000 mAh battery.  The one I received looked just like it but was a 15,000 mAh battery.  I'm not sure if that listing is wrong or if I was sent the wrong battery model.

This second link is one I didn't order but is a 15,000 mAh battery that looks just like it.  I'm guessing I was sent the wrong one in my initial order but I'm not entirely sure.  I wanted to provide this one since it seems like it may have actually been the one I was sent.  I tried to check the dimensions listed on Amazon to see if that would tell me which one it was but the dimensions for both are way off what I can measure with my calipers.
