Hi all,
I have been creating my own charging station using a mix of Opus BT-C3100, pictures below.
I have 4 Opus and 1 Liitokala, all needing 12V, 2A - 3A. I want to power them using a computer PSU.
Since I am notusing the supplied adapters I cut the individual power supplies, connected all the positives and then all the negatives together. I soldered them to a switch (rated for 240 or 120V, since I couldn't find for 12V).
I am getting strange results with my setup. The Opus are causing a short when plugged in and they trip the power supply. When I measure connectivity between the -ve and +ve going to the Opus, I get a closed circuit for an initial ~5seconds which then clears. When I plug them in, they computer PSU justtrips.
When I connect only 1, it works fine and if I plug in the other 3 without (using the jack at the top of the OPus), they are all registerfine and they can be used. However, when I switch off using my switch, the PSU trips again.
Have anyone experienced this issue?
The TP4056 are working fine with no issues.
Any help will be appreciated
