Observing Tip:

If you're using this with a mount that draws significant power—like a CEM40 or larger—consider carrying two power banks to swap between sessions, or keep the charger connected at a star party with AC access. For smaller mounts or visual use, one charge will often get you through an entire evening without a hitch.
