Looking for a low noise 12v USB charger

[Paul L]

I'm looking to install some bulkhead mounted USB chargers, like the Blueseas one below. Some of the reviews of it complain about RFI on SSB frequencies. I don't want to add anymore RFI to the boat. Anyone know of a good low RFI charger?

I am not trying to be cute, but install a cigarette lighter receptacle and then plug in a dual USB charger, unplugged of course it won't be noisy. You can then use it for other things like charging a handheld or whatever else uses a cigarette lighter plug.

I already have a number of them. They all end up dying after awhile or end up making poor connections to the cig lighter. Its less of a mess if there was a built in outlet.

We have a blue sea cig plug in dual USB charger and have been using it for a couple of years. no SSB interference at all. Never had any issues with it becoming loose or breaking the connection with the cig lighter receptacle

I did see a combo 110v wall outlet that contained two USB plugs. Google Hubble USB receptacle. These replace the normal wall receptacle but then you have to have 110v running to it. I like the 12v solution as I don't need the inventor to be on.

I have 5 lighter receptacles, one in the bow and one in cockpit, one at the Nav desk and I have installed two in the fwd Stateroom to run our CPAP machines.
The one in the bow and cockpit I think were factory installs, if so that makes them 30 yrs old and they work.
Lighter receptacles are bad about what you plug into them not keeping a good contact, and contrary to what you would think, I don't think you can pull significant amps through them, things like portable coolers are better off using a "real" plug etc. But for USB chargers I have found them to work fine, the one beside the chart table I have a four USB charger plugged into it most of the time, and when we are away from the boat I plug in an air Purifier, something that I feel I may have wasted money on, I don't think it does much really
