Found that we needed a PD (power delivery - 20W) charging port for Ipad to keep up with the power draw running Navionics. Fortunately there are 2 unused rocker switches on our 2021 R27. We replaced the lower rocker switch with this unit from Amazon. The swap out was easy and Ipad now stays charged.

Does anybody know approximately how long a 100% charged iPad 8 will run Navionics without a charger. (Use airplane mode and 50% screen brightness)
Why not just plug a PD charger into 12v outlet at helm instead of a rocker switch?

The standard USB outlet at the helm will output 12 watts, which is insufficient to charge an iPad.
 
I have a 2017 R29. It has no USB. It has a 12v outlet. It is a "cigarette" style.
As far as I know, the max watts output is fuse amps x 12V. Am I thinking right?

They don't do the cigarette lighter outlets there anymore. Only one installed is in the cave on the R27-OB to run like an air pump for inflatables or something.
The helm, v-berth and port side outlets are USB charging ports. USB-A usually. 12 watt ports.

Martin:

Do you know the capacity of the 12v cigarette lighter style of outlets?
 
The best way I've found to charge all our devices on the boat, iPad's, phones, laptops, is not by upgrading the USB port outlets on the boat. I leave those just so they can charge my phone, and that's all I expect out of them.

We picked up a couple of bricks. Anker 737 Power Banks. They are 24,000 mAh. They are capable of being charged at 140 watts, so they recharge fast. We pass them around all over the boat. They are portable USB ports wherever we are in the boat. They pair nicely with an Anker 6 in 1 charging station that is capable of charging them at 140 watts.

Our MacBook pro's draw 60 watts when plugged in. Ipad's are 20watts. IPhones are 12 or 18 watts, depending.
Each Anker 737 will recharge our laptop battery once. It'll do an iPad multiple times. It'll charge an iPhone 5 times.

This is what they look like.
 
I use an AC plug and 6 ft cable under the table in our R29 when underway.
 
Usually less than 10 amps at 12volts.
The key word here is “less”!

On a recent trip home we connected our Jackery power station to a 12v cigarette port (10 amp rating) with the supplied cable for charging underway. Upon arriving at or home portfor fuel we smelled burnt plastic! Upon inspection the port was very hot and melting! I replaced both the receptacle and plug and no longer use cigarette plugs for charging high current devices. We now use our 35 amp Scotty down-rigger plugs for charging the power station.

PSA: The 12v cigarette connector can easily become loose with vibration underway resulting in a poor connection. While rated for this current this connector is subject to poor connection due vibration. I would not recommend using this connection underway for charging at this rate.
