The other thing to consider is that your trickle-charger might not have been engineered for long-term continuous use.
I'll double that.

You can, nevertheless, build your own heavier duty supply if you're a bit familiar in DIY electronics...

I did that myself for when my boat is ashore for maintenance and it is yet to let me down...
