Mac charger overheat while on shore power

[Freedom32]

Not sure how this works. UGH. I need to work from my boat so I need to charge the Iphone and Macbook Pro.

Hooked up to shore power to outlet (grounded 3 prong adapter hooked to marinco 30 amp service at marina) I plugged my MacBook pro charger in. Should be getting 110 out of the outlets. My charger got really hot after about 15 minutes.

I haven't had any other issues with charging heat on VHF handheld or any other thing that I have plugged in.

Am I doing something wrong here? Need a converter? Some obscure issue with current.

Help!

They normally get can get very hot but if they are getting very very hot its possible that two of the pins are not making good contact. Clean the ends of the plug using alcohol.

First thing I would do is go plug it into an AC outlet somewhere else and confirm it’s getting hotter on your boat. It may be normal and you’re just paranoid (no wait, vigilant!).

If it’s not normal then strikes me that Zboss is right. Assuming the boat is new to you I would replace the receptacle (they’re cheap) as the contacts might be corroded. When you do give the wires a close inspection for blackening or other evidence of heat. If you find anything I’d go over the AC on the whole boat, change the receptacles. I’d also add a GFCI to the first receptacle in the circuit if you don’t have one already.

I’d also check your shorepower socket at the boat.
