I've seen alot of docks that have power to them - I got a second small one at a yard sale and made sure it worked. Usually have it in a box with a few rolls of bags in the trunk when going on trips like that.
You need the vacuum sealer that is D/C and also A/C,like us real fishermen have,lol.J/K,I have the regular FoodSaver,the other one is on my Wishlist,hate to buy something when the one I have works just fine.
I need to get some more bags before season starts. Someone said to head to one of the Dollar stores, they are cheap there.
I can't see spending $$ on another one either Salty while this one works, and my Mom has one she wants to give me.
