Hello forum, one quick question. Should I keep the engine running or turn it off when I want you use the electricity accessory sockets? For example to use the air pump, which takes 30A.

Also when using my car to give someone else a jump start from my battery. Is it better to keep the engine running? or better turn it off?

Thanks

Are the 'power points' (formerly known as Lighter Sockets) fused for 30 amps? Somewhere ISTR they were fused for 10A.

I'd run the engine for the air pump.

If anything you are going to do will draw significant current from the vehicle then start the engine first, because you do not want 10+ amp continuous drains on your battery. Jump starting a car, or running a high current (greater than 5 amps) accessory therefore .... best practice is to do so with the engine running.

Note: accessory 12v sockets in Hondas are spec limited for 10 amps I believe. If you want to do true high current 12v power delivery to something like a compressor or other high current device... you will need a special wiring connection and high amp fusing to protect both the vehicle and the wiring FIRST.

If by Compressor the OP means a 12V tire/air mattress inflator, I just looked up this one. It draws 10 Amps, and that would be fine to use on the cigarette lighter.

Thanks for the comments. Yes, by air pump, I mean an small electric compressor used to pump up tires.

The accessory sockets in my 2008 CR-V are fused to 15A. I have three accessory sockets, one in the front, one in the center console and one in the rear cargo area. The compressor I'm using is a compressor that I got from an Audi Q5 and it actually doesn't say the current it takes. I don't know where I got the 30A figure from, but I guess it was a confusion.

In the past, I blew two of those 15A accessory sockets fuses, and as I couldn't find the 15A fuses, I replaced them with 20A fuses. Should I put on the right fuses? Or 5A difference won't burn my wires?

Cigarette lighter will be fine. Use with engine on. My friends did the same with a aircompressor, but with the battery off. They needed a jump start after. :ROFLMAO:

When it comes to fuses you should replace with same amp rating. Otherwise it could cause damage to the circuit and may cause a fire. In a pinch, I've replaced fuses with a higher amp rating (temporarily)same as you. I wouldn't tempt fate any longer than I have to.

A tire inflator should be no issue as they are designed to be used with 12v accessory sockets and I doubt very much they draw more than a few amps.

There should be a fuse somewhere on the compressor, and that fuse value will give you an idea of the maximum current draw of the compressor. So if you can find that, or look up the owners manual online, you can determine the power requirements of that old Audi inflator.

While Honda is conservative on how is specs things, and as such a slightly larger fuse (15 rather than 10) probably will cause no issue, it is always prudent to stay inside Honda specifications. So if it were me, I would replace those improper 15A fuses with the fuse spec from Honda.

If this is not proof enough NOT to use that air pump with your cigarettes lighter plug I don't know what is.

buying a pump that doesn't uses that much current is a better option though

using a higher rated fuse will increase the chances if not to cause permanent damage to the wiring. There is a reason those fuses keep blowing up. Not to mention what ever else gets destroyed by that melt down of wiring.

If you feel like using that air pump, best advice I can offer is to cut the ends of the wires and install an inline fuse holder and also use clamps designed for battery terminals. Like those of jumper cables(smaller pieces are sold).
Yes this means plugging it to the battery terminals instead of the comfort of the CL plug,
But at least you know nothing else will be damaged in the process.

Pick the one you like the most.

I try to never attach anything to my car's electrical system that didn't come with the car. Computers and voltage spikes don't get along well.
That's why I use a self-powered air pump. Charge it at home and it can pump up a dozen tires.
I would never jump anyone from my car, but I do carry a lithium jump starter in case I encounter someone needing a jump.
I note the Hybrid's manual talks about jumping TO the hybrid, but is silent about jumping FROM it.

Thanks guys. I'll try to be more conservative in the future I guess.
