I use this one on my acoustic:

I also have the one @Bricksnbeatles points out which is really low profile. I use that on electric if I'm not plugged into the pedalboard. Here you can see my G-string is way flat.
Neither of these are rechargeable but batteries have lasted a very long time for them.
