Is a 20amp dock outlet enough to power the battery charger and outlets on a C32

[DMC3]

I am currently upgrading from a 2012 R25 to 2022 C32. I have a standard 20amp outlet on my dock. With the R25 that was enough to power the battery charger and the outlets to run a dehumidifier. I know this is not enough amps to run high amp equipment like the air conditioner.
Will the 20amp curcuit be enough power to run the battery charger and a dehumidifier on a C32?

Very likely that's enough, how many watts is your dehumidifier and how many amps is your battery charger?

With 20 amps you have 2400W of power, probably want to keep it around 2250W so you aren't at 100% load. Your dehumidifier probably also doesn't have soft start, so that is going to spike power draw while turning on the compressor.

However assuming the average dehumidifier is 1000W, and even if you have a really big 50amp 12V battery charger (50*12V*1.1(inefficiency factor)=660W) You're still well within the limits at 1660W.

To my understanding on our 2023 R27, everything runs off the inverter/house batteries. I believe all the shore power does is charge the batteries. Given that there is no changeover switch, and the A/C and 110 outlets will all work without shore power.
I mostly just use a 10 gauge extension cord and plug into the 20 amp to keep the batteries charged. Now, I haven't tested it to know if the 20 amps will keep up with the draw of the A/C or dehumidifier. But, it does charge batteries fairly quickly. My guess is that it would. I would give it a test for a couple hours and see what your battery draw is.

The dehumidifier is a table top model and only draws 65w so, it sounds like I am good from that standpoint. From my understanding the Cutwater 32 has an inverter/charger. It can only function in one mode at a time. If it plugged into shore power it is charging and cannot function as an inverter. The outlets are powered by the shore power not the batteries.
Based on the comments I should be able to get by the 20amp circuit. That will save me having to run a 30amp circuit to the dock. The quote was $2500.
Thanks for the help.

Until I rewired my dock, I was using a 20-amp GFCI circuit to operate the inverter and dehumidifiers for 3 years.

I was on a 20amp circuit for a year with my 32CB, until Hurricane Helene flooded the dock and they upgraded to modern code. I had two little solid state dehumidifiers and the battery charger on with no problem. Even got one of the AC units to run sometimes.
