Product Details

The SmartPlug B50ASSY 50 Amp Inlet Connector Combo Kit provides everything needed to upgrade your boat's shore power connection with superior overheat protection and reliability. This complete kit includes both the boat inlet and boatside connector, allowing you to replace the boat end of your existing shore power cable with SmartPlug's innovative design that eliminates the common failure points of traditional NEMA twist-lock connectors.

Complete Kit Includes:

  • SmartPlug 50A Boatside Connector with blue LED power indicator
  • Stainless Steel 50A Boat Inlet
  • Rear Mounting Gasket for weatherproof installation
  • Cable Strain Relief
  • Hex Key for installation
  • Complete installation instructions

Key Features and Benefits:

  • Enhanced electrical contact: Straight nickel-plated brass pins provide 20 times more surface area than curved NEMA pins, dramatically reducing resistance and heat buildup
  • No twisting required: Unique plug body shape ensures correct alignment every time—simply push straight in until spring-loaded side clips lock automatically
  • Superior materials: All external metals are marine-grade 316 stainless steel for maximum corrosion resistance
  • Secure connection: Sleeve design fits snugly within the inlet, eliminating movement and tension on electrical contacts
  • Weatherproof construction: TPE Dyna-flex cord seal provides reliable protection against moisture intrusion
  • Integrated locking: Inlet cover snaps securely onto connector sides and top—no plastic locking rings to strip or crack
  • Visual power confirmation: Blue LED indicator light on connector top glows when shore power is connected
  • Easy retrofit installation: Mounts using industry-standard hole pattern compatible with Hubbell, Marinco, and other leading brands

The SmartPlug system addresses the fundamental design flaws of traditional twist-lock connectors by eliminating curved pins, reducing connection movement, and providing foolproof installation. Ideal for sailboats, powerboats, fishing boats, and yachts requiring reliable 50-amp shore power connectivity.

Item in-stock and shipped fast. Will definitely buy again from seller.

ordered 4 cans to prime/paint/clear coat some rims. paint came in 2-3 days (incredibly fast). They forgot a can, i emailed and got a reply within 20 minutes, and the can was on my doorstep the next day. im very impressed

Fantastic prices + free shipping! What more could one ask for? Looking forward to my new coilover kit! Cheers!

Fast service

Ordered some parts the other day and was impressed, will see if it was a fluke.

20.00 bucks cheaper than summit and ebay on my k&n pod filters for my bike. Ordered on thursday night and product shipped monday. Otherwise great deal.

So far, so good!

Exceeded my expectations searching and ordering

Ordering was easy and hoping it ships as fast. Price was great.

Easy

Very easy to use

well so far

excellent company with great prices and even better customer service. my order arrived, and too my surprise i found that it was not the product i had ordered. the customer service was prompt and i was informed that unknown to autoplicity, the product i ordered was discontinued by the manufacturer and what i recieved was their replacement. this was all unknown to autoplicity and they apoligized sincerely and have rectified the issue very much to my satifaction. the product itself arrived in perfect condition and meets or exceeds my expectations. i will look forward to shopping with autoplicity again due to their great prices and excellent customer service.

I ordered a rear sway bar for my MINI Cooper on Sunday and it was at my door on Wednesday! Autoplicity had the absolute cheapest price for this bar and I was very impressed with the shipping speed. I would definitely recommend them to my friends!
