I bought a spare battery for my Trend Airshield Pro, and I got a Tenergy charger and built a simple wooden charging base like the one Mike Peace shows in this video so I could always have a charged battery ready to go:

But my charging base didn't work terribly well (unreliable contact with battery terminals) and looked awful, so I asked my son if he could make something better. He's been designing various 3D-printed mounts and attachments for his school robotics team and is getting pretty good at CAD modeling. This is what he whipped up for me in an afternoon. It works perfectly, and looks a lot better than the one I glued together from scrap wood!
