Easy to install after cutting holes to the template you need to download/print the .pdf installation instructions from the etrailer.com webpage. I did not expect the screws which come with it to secure in the steel bumper. Purchased screws and lock nuts to secure. Now I do not have an ugly plug hanging down!

Already had somebody notice it today after wondering what it was when looking at my steel bumper at a local store.

Supposed to get down below 32 degrees tonight so I will use it for the first time to keep my diesel engine warm.

Used multiple times over the winter. Worked great. Still get jealous looks questions about it.

by: Perfect 05/13/2019 One Year Later

I used this on my dump trailer so I could easily charge my battery without opening my lock box exposing the battery and hydraulic pump. Works great!! The adapter will receive a large plug end. See photos.

Was looking for a two way plug to serve as a shore tie port so that it wouldn't be necessary to cut off the plug end of my new onboard battery charger and then hard wire. This product achieved that objective, albeit with a short pigtail, which also allows plugging something else to the shore tie port. Straightforward installation.

Just what I needed for our lithium battery golf cart conversion. Fits into the the location where the club car charger used to plug in.

by: Ronald 04/15/2019

It is made well and is exactly what I was looking for. It is installed on my 2017 Nissan Titan XD Diesel 4x4 pickup truck now for the diesel engine block heater power supply. I just have to take an extension cord and plug into the truck in when needed.

I used my ac plug port for the onboard charger on my golf cart. It works great, and looks clean. The only reason this is not a five star rating is because etrailer had a bit of trouble getting this product to me.

Very good product. Easy installation. Works great. Use in my 5x8 enclosed trailer with a power strip inside which includes USB ports for phone and such. Mounted under trailer and up front. Didn’t want to drill into the side however it comes with very robust weather proof gaskets so won’t be a problem for someone who needs on the side.

by: Darren 02/01/2018

Definitely beats having your block heater cord hanging out of the bumper or grille. Part was initially on back order which I discovered after placing my order. The 5 star rating is more towards the company than the product. George J was very prompt on informing me of the situation and expected ship date. Its almost unheard of in the age of texhnology to actually receive a phone call to let me know. Keep up the good work guys! You have earned my business on customer service alone.

works good

Very good deal on an AC port plug. I installed this on my enclosed trailer to run battery chargers while I'm not using it. The quality exceeded my expectations and installation was very easy.

by: Matt 02/06/2019

Excellent product at a great price,easily installed.great way to have power inside my snowmobile trailer rather than running extension cord between ramps or side door

by: Sandy McDonald 04/29/2024

The electric port itself is fine, however, the three screws which are supposed to hold in place needs work. IVe had an electric cart now for almost a yr. The original same port was there. The problem is that those three screws vibrate out and get loose causing the port to be loose and when trying to remove the electric cord from charging causes the wiggle struggle. The ground on the port itself broke off, thus the reason for my order for a new one. I have replaced the screws with small bolts the same size and included washer and nut to firmly hold in place.

Maybe you all could examine for further use? Just a suggestion. Thanks

easy install, weathertight, holding up well after several months.
i use if for trickle charger on motorcycle in enclosed trailer.

by: Rhys 02/11/2025

Honestly, I expected the sealing cap to be some kind of plastic that I foresaw breaking in extreme cold. Having this in my hands exceeds my expectations as the quality looks to be very well made and the plug is of a rubber that I think could be very durable in the long run.

Great external 110V port for my boat, internal female 3 prong plug connects to my boat battery charger!

Recommended SAE and 110V Connectors for an RV
Hey Domingo, thanks for reaching out to us! We don't have a setup with both of those ports combined, but I do have separate ports for each type of connection you're looking for: - SAE # GP49QR - 110V # 329-GCP1 Both of these come with plug to protect them from the elements when you aren't using them.

Battery Charger for 4 Batteries In Parallel on Kenworth Truck
Hi Joe; the CTEK you're referring to has been discontinued. For the 4 batteries I recommend the NOCO GENPRO On-Board Battery Charger # NOC84FR. This is designed to charge/maintain 4 12V batteries simultaneously up to 230 amp-hours. This uses your standard AC plug and can be used with the NOCO AC Port Plug # 329-GCP1 if you want to make it easy to run an extension cord. If you're trying to charge them while driving you would need the Redarc In-Vehicle BCDC Battery Charger # 331-BCDC1225D...

Does the Warranty of the NOCO AC Port Plug Cover the Ground Pin Breaking Off
I have not personally heard of that being an issue with the NOCO AC Port Plug # 329-GCP1. But, I did reach out to the manufacturer about if it would be covered. They said that as long as this happened within the 1-year warranty period, we would be able to cover it under warranty.

Recommendations for Charging Small Trailer Battery with DC and AC power
I have two components that will work together to do what you're hoping, but there isn't an all in one option that pulls power from your truck and also plugs into shore power. For the DC I recommend the BC-DC Charger # RED96FR which is good for a battery less than 75 amp hours like it sounds yours is. This will tie into the 12v power from your truck and keep your battery completely charged while not overcharging. You'll also need two # RED76FR and some wire you'll need to pick up locally...

Charger Capable of Charging a 48 Volt Golf Cart
Yes, we have the NOCO Genius UltraSafe Industrial Battery Charger # 329-GX4820 for 48 volt applications. This is a 20 amp charger with 6 charging profiles that is safe for lead acid, AGM and Lithium batteries. A NOCO AC Port Plug # 329-GCP1 can be added if you want to mount the charger on the golf cart and run an extension cord to the cart when you need to charge.

Parts Needed To Recharge An Enclosed Trailer Battery With Shore Power
You'll need to start by installing a power inlet like the NOCO AC Port Plug # 329-GCP1 to get your shore power connection. From there you can install a battery charger like the NOCO Genius # 329-GENIUS10 to keep the batteries charged while at the job site.

Does NOCO AC Port Plug with Extension Cord # 329-GCP1 Have 14 Gauge Wire
Yes the NOCO AC Port Plug with Extension Cord # 329-GCP1 does use 14 gauge wire and is also rated for 15 amps.

Can NOCO 329-GCP1 Be Directly Wired to Oulet
The female end of the # 329-GCP1 could be removed and directly connected to an outlet if you wish, although the product wasn't designed for use in that manner.

Recommended Chargers for 4 Battery and 2 Battery Banks on 2004 Discovery 39 Class A Diesel
To charge the 4 battery bank on your 2004 Discovery 39 I recommend using the NOCO GENPRO On-Board Battery Charger - AC to DC - Waterproof - 4 Bank - 12V - 40 Amp # NOC84FR, which will charge batteries rated for up to 230 amp hours. You can also add the NOCO AC Port Plug with Extension Cord - 16" Long # 329-GCP1 to this setup to allow you to plug an extension directly into the coach since this setup will likely be stored in a cargo hold, out of the elements. For your engine batteries,...
