Have you shopped inverters? There are quite a number like this one which have regular outlets for plugging in your laptop charger, and also USB ports for charging your phone, etc.
The most common ones top out at 300W because that is the current limit of the cigarette lighter fuse. Ones with higher output need to be wired directly to the 12V battery, not plugged in to the lighter.
Do tell us what kind you get!
You would want an auto inverter. Something like this.
That is great! I have not tested this using a cigarette lighter as the power source, and each car is different. I would hope it would work, my only concern is the cigarette plug on your car. otherwise if it doesn't, maybe you could run a positive wire direct to the battery along with a automotive inline fuse, and then connect the negative wire to the body/frame (Seat bolt makes a good negative connection on a car). And here is a link decent little inverter that should do the trick and leave some extra power for powering other devices too. Just remember to turn off the inverter if your car is off because then you are stranded! https://www.amazon.com/BESTEK-300Watt-Power-Inverter-Adapter/dp/B07KQ4Q2L5/
As someone who got into sine inverters 8 years ago, I'll never go back. Now efficient power handling gives you more bang for your buck in what you can run. They're also better for your expensive electronics.
Here's the little travel I use in rental cars for charging my laptop
I have a much bigger one in my truck and run a freezer and air fryer, etc on it.
Can you look on the pump and see how much wattage it uses? Should say somewhere. I picked one at random, might work, but if the wattage is higher than that one I'm sure you can get a little power inverter that can handle more wattage and might work for you. Again, picked one at random, can probably get what you need between $20-50, but will depend on if you need 150, 300, 500 watts etc. If you have amazon prime, free returns if it doesn't work.
I would also recommend getting an inverter and using it with your current AC adapter, then it would be pretty much the same as having it plugged into the wall.
If possible, I'd recommend a true or pure sinewave inverter, such as the BESTEK 300Watt Pure Sine Wave Power Inverter Car Adapter which is the pure sinewave version that's been recommended earlier. https://www.amazon.com/dp/B07KQ4Q2L5/
It does cost a little bit more, but the "cleaner" power means that it should have no problems powering even the most sensitive devices that you have.
If you use the adapter you are talking about, then it will probably end up running flat out, which will tend to result in it running hot, and well that's usually not a good/great thing.
It should help extend battery life as long as the laptop's power management system allows for it to do so. If the laptop is "off" then it also should charge the battery, but it probably will take longer than it usually does when used with it's AC adapter.
But you really won't know what will happen, until you hook it up and give it a try/test.
Also make sure that the connector is the right size and polarity, because it either won't fit or in the case of polarity, bad things tend to happen.
I'd probably go no smaller than a 300 watt inverter, because the AC adapter sounds like it's a 200 watt unit. It's always best to have a little extra overhead, that way you can plug a second or more items in, and the unit should run relatively cool or cooler than it would, if it was a 200 watt unit, it would probably be maxed out, and that's something that should be avoided if possible.
Best wishes and good luck!
Gaming laptops use a lot of wattage. You need an inverter that plugs into the 12v charger. A 400w inverter should work to charge the laptop. You can try playing games with it plugged in like that, but it might not give you enough juice. I'm a truck driver and I've used those inverters with older gaming laptops and they always blow out. However, it should be fine just to charge your Helios.
The power rating is never what the inverter actually puts out. They are not expensive and worth a try. You can find them at most truck stops or travel centers. Amazon has them too. Look for a pure sine wave inverter like this
https://www.amazon.com/dp/B07KQ4Q2L5/ref=cm_sw_r_cp_apa_i_d6UIFb11YYERJ
I've read that pure sine wave puts out cleaner power and it might work to actually power your laptop and let you game plugged in. I mentioned a 400w earlier because that was the most powerful inverter that you could plug into the 12v plug. If you go bigger, then you have to connect the inverter directly to the truck battery.
Sorry for the long post. Hope this helps.
Honestly the easiest way is to get a small 12V inverter to 120 volts out. Very slightly less efficient but quick and easy. I recommend finding a sine wave inverter.
Here is one under $50, and the benefit is that you can use it for other things as well.
I haven't done this, but I happened to be googling this very thing last night and apparently people have had up to 1000w inverters installed and used them to power household devices during hurricanes. That was described as the upper limit.
I would do more research before buying, but I did want to comment that at 300W you ought to get a pure sine wave model instead, especially if using on sensitive electronics.
E.g.
BESTEK 300Watt Pure Sine Wave Power Inverter Car Adapter DC 12V to AC 110V with 4.2A Dual Smart USB Ports https://www.amazon.com/dp/B07KQ4Q2L5/ref=cm_sw_r_cp_api_i_VvXWCb74HFNZZ Pure sine is always the better option IMO. I ordered this one. It had great reviews online and it didn’t require a direct connection to my battery. There’s a power outlet in the cargo area so it’s perfect what I’m doing.
I believe that the bit you need for this is an inverter, this is a gadget that turns the DC (battery type) power of the battery, into AC (wall outlet type) power so you can simply plug it in. there are ones of all sizes, the main spec is the wattage,
from what Google says, an inverter like this:
https://www.amazon.com/BESTEK-300Watt-Power-Inverter-Adapter/dp/B07KQ4Q2L5/
would probably be plenty for this sort of thing , and with a hefty battery to hook it to, anything else I would think that was needed would be basic stuff for making a box to hold the battery and inverter for it to be easier and safer to carry or whatever.
some of the time those inverters come with clamps that can be used to hook it straight to a battery. this specific one comes with the cigarette lighter adapter. but he should be able to make it work.
Something like this one is all you can run off the, um, powerpoint aka lighter. The lighter has a fuse that will blow above that amount of drain. (n.b. the fuses are found in a box under the hood and if you're going to fool with this stuff you might carry spare fuses and know how to change them.)
What you want is something like this one which needs to be connected directly to the 12V battery. That lives in the back, you know where? Any auto-electric outfit that does stereo installations and such, should be able to do a neat job of connecting it. You'd want to find a way to stabilize it so it doesn't ramble around the trunk when you hit the brakes. Velcro, duct tape, something.
And yes, the Prius 12V battery is a pitiful little thing that won't stand putting out 1000W for very long, unless the vehicle is in "run" mode, then it gets charged continually.
I found the same looking this year for a replacement TV. LG, Samsung and Sony all had TVs with external power bricks ~5 years ago. I can't find any today. This inverter has worked for me, but I'm not trying to also power a DVD player.
I suggest you look at ripping your DVD collection with Handbrake. Install LibreELEC on a Raspberry Pi. Get a large microSD card or USB drive. Depending on how highly you compress your movies, a 512GB drive can hold up to 500 movies. Costco has 400GB microSD cards for $50. Much more convenient than carrying around a huge DVD collection.
Litter won't work for moisture. I used a cracked window, battery operated fan and damp rid in my small RV. When I had power, I used a small dehumidifier. I suppose if you have a converter like this you can order one of these (probably cheaper on Amazon). These are the dehumidifiers I used in the RV. One would be good for a car.
this is what i use, havent had any problems so far (2weeks)
I put one of these in the cig lighter (enough for work laptop and monitor - but can't handle my gaming laptop): https://www.amazon.com/gp/product/B07KQ4Q2L5/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1
I bought a pure sine wave power inverter
BESTEK 300Watt Pure Sine Wave Power Inverter Car Adapter DC 12V to AC 110V with 4.2A Dual Smart USB Ports https://www.amazon.com/dp/B07KQ4Q2L5/ref=cm_sw_r_cp_api_i_PVqIFbNJFQHB5
I was thinking of getting a power inverter LIKE THIS ONE and just using the charger that comes with the Air2.
You're very welcome! I'm using this as a secondary inverter when we don't need the victron 800. https://www.amazon.com/dp/B07KQ4Q2L5/ref=cm_sw_r_cp_apa_i_MwdyFbWP9S9V3
Yes it hooks up to your car battery. Your fridge/freezer mostly likely pulls 800+ watts, a direct 12v inverter will be necessary. This wiring kit comes to set that up to the inverter. They were really popular during hurricane season. https://www.evextend.com/Emergency-Power-Kit.php Bit of a sticker shock on the price, but in my experience with car stereos which require a similar set up, it is not outlandishly expensive.
Cigarette lighter circuit for sure won’t be able to power any fridge greater than a mini fridge, which this inverter can do if you’re interested. https://www.amazon.com/dp/B07KQ4Q2L5/ref=cm_sw_r_cp_api_i_IzVUDb0KCHHK8.
