Just an update to my situation. As a recap: I contacted cloupor, they told me to send them a video showing that my cloupor is not firing properly.
Well, I did so weeks ago and never heard back. So I'm chalking this up as a loss. Maybe Chinese new year has something to do with their lack of response, but I dunno. Maybe I will hear from them at some point but I do not expect any kind of resolution at all.
I hear that the
ipv Mini 30W also has this issue where using as passthrough and charging the battery internally fries the circuit board. I have an
ipv mini 30W and never used it as passthrough or charged internally and so far so good. In fact, I love my IPV mini much more than the cloupor, even though it's not nearly as small and hardly "mini", at least by today's standards.
My suggestion to any cloupor mini owners would be not not use passthrough or charge battery internally.
