I blew the fuse for the lighter socket for the second time

I'm totally to blame. I run too many accessories at the same time. This time it was the vibrating seat cushion that broke the camel's back. I decided to use a 20 amp breaker in place of the 15 amp fuse. Since I don't bend that way, I took it to a local repair shop, where they installed it for free. The mechanic advised against it, but I said I was doing it anyway. I have no problem at all driving 20 amps through that circuit.

I run several chargers, a cellphone booster, a dashcam, a radar detector, and the back massager. Now, if it blows again, I'll know when to disconnect some of them, but I won't have to replace a fuse.

 

I learned about the limits of the lighter socket in my Gen 3 from a close call. That one is protected by a 10 amp fuse, and I may have upgraded the fuse; I don't recall.

But when I plugged in my truckers oven (heated lunchbox) I smelled hot plastic, so I unplugged it right away. No apparent harm to it anyhow. I installed a socket directly off the battery, with a long extension cable instead. I'm sure it was fused at 20 amps. No problem with that setup at all.

 

Of course I knew. But I feel confident in my choice.
I knew someone would be eager to criticize my decision.
