I have these with the Kyosho brand for Mini-Z and they are really spectacular.
The problem is that Kyosho charges $30 for one of these!

Super small, great app.

This charger is really, really small. It can only charge, but that's completely okay for my use-case. The app works well, the light-indicators are useful.
