Just remember, you'll have a hard time peaking at 120w without popping the cigarette lighter fuse in your car, let alone 300w.

If you need that much power, hook it to the battery. Way too many BS cigarette lighter inverters out there pretending they can magically defy Ohm's law.

Picked up the 300W...can't beat $13. May come in handy.

A perhaps stupid question, but is there such a thing as a USB inverter, i.e. one that runs off of a 5V USB input instead of a 12v cigarette lighter jack one? With all these high-capacity USB power banks these days, it seems like an obvious next step, so long as you don't connect anything that draws too much power to it. E.g. LED lamps & small radios as opposed to a toaster or large fan. But with some power banks putting out 3A @5V, that's 15W, more than enough for light use.
I won't say they don't exist, but they'll be more expensive than most people will accept. Doubtful that they'll ever see common production because people are dumb and will wonder why their laptop isn't charging from the USB port in their car.

Regardless, anything that runs off of that little power will often have a USB variant available anyway. Skip the converter and just get a USB powered lamp or radio.

EDIT: as for the 60w/9w equivalent, look for 800 lumens. 9w is still a lot to be pulling from USB, so there aren't going to be many that plug directly into USB, but it's a good place to start looking.

FWIW, my 2016 Accord has a 7.5A fuse for the front accessory socket, so 90W max, but the rear socket, inside the console, has a 20A fuse so 240W Max. I'm going with the 300 and will keep some extra 20A fuses in my car.

Dang, not bad. Definitely YMMV based on the car itself.
Still, it's always funny to see people try to run a microwave off of their Cigarette lighter.

I believe you have to wire right into the 12V lead of your car to get 300W on these things.

Pure sine wave inverter?

Thanks, that what I assumed, just wanted to make sure. And as you say it makes more sense to stick with USB all the way. Cheaper, simpler, and you avoid the efficiency losses from upconverting to 120AC than downconverting to low-volt DC.

But I'm still not sure what kind of LED light source to look for. Ideally it would look like a traditional light bulb for esthetics and simplicity, but mostly I'm looking for something that will approximate the light output, in intensity, color and coverage, of a standard 60W equivalent daylight LED bulb, and work off a 2.1~2.4A 5v USB output, so it could be powered from a USB power bank or adapter.

I'm sure there's a gazillion of these out there, but I don't know where to look or what to look for. Or, if I built one myself, what kinds of LEDs, circuit board and other accessories I'd need. I'm handy enough with circuitry at this point to build one myself. Might even add dimming, smart switching, WiFi or RF to make it fancy.

LED lamps & small radios as opposed to a toaster or large fan. But with some power banks putting out 3A @5V, that's 15W, more than enough for light use.

I'm sure that it CAN be done. The real question is whether it's worth making one given the relatively little power they could put out. My main reason for asking is because I have a 10-12W solar panel and I'm curious to see if it can power a small lamp I have that has a 60W equivalent 9W LED bulb in it, via a power bank that's charged up during the day by the panel.

Alternatively, I could power LEDs that put out an equivalent amount of light directly, without the complexity, cost and efficiency loss of first upconverting to AC, only to have it downconverted back to DC. But I'm not sure what kinds of LEDs can put out an amount of light comparable to a 60W equivalent LED bulb. Any clues? If I could put together such a lamp that had a USB input, this would obviate the need for the USB inverter.
For a 60w equivalent you need around 800 lumens. I have a USB light bar that draws 1w and it says it puts out 20lumens but I feel it's much brighter then that.

Grabbed the small one for travel. I've converted everything I could to charge off USB, but I use a Dell tablet to facilitate photo backups, and it has no straight DC charging option available.

Is that a 4 cylinder variant?
