Unsure if this is what you're looking for. To convert DC to AC you need an inverter.

u/dread_pirate_bobert · 5 pointsr/BuyItForLife

I've got a good one for you.

My wife and I work from home and we recently set off to travel the country and work from a trailer. You are in luck because I did a ton of research on making sure my laptop had juice.

Also if you decide if you do not like this stuff, you may want to change up your search terms because you don't want a generator. Search instead for a power bank

Here is the one that I purchased

It has worked really well for me and I used it daily. The downside is it is a 15 volt charge. This means it is suited to be charged by solar and is slow to charge. So make sure to charge it daily when you get home.

If you want to learn a bit more, there's some technical stuff below.

Another bit of warning to you. Any battery/powerbank is going to run off of DC current. Your laptop also runs off DC current. However, plugs to your house are AC current. So you have a power cord that converts AC into DC for your laptop to run. Everytime you convert from AC to DC you lose energy. So when you have a DC power bank, you have to convert to AC, then your charger converts it back from AC to DC. So you get WAY less battery life.

Because of this I also purchased a DC charger for my computer. It upped the power bank from one full charge to 3 full charges.

This is the DC charger I purchased. Make sure you look up how many watts your laptop needs to run.

Other power bank info

Try not to completely discharge the battery. Let it get to %25 then turn it off and recharge. It doesn't destroy the battery if you totally juice it, but it will lower its life expectancy every time.

Make sure to charge it if you don't expect to use it for a while

Don't drop it

Don't get it wet.

**Ninja edit - this is not a buy it for life...No battery storage system will ever be a buy it for life. At least not one that exists today. Batteries have an expected cycle limit. If you treat your batteries bad the cycle limit will be 200. If you treat it well it can be as high as 500.

Earwigs would be absolutely ideal, but sadly the production (an indie short) is overbudget and can't cough up the ~$250/day to compensate me for the rental of a basestation and an earpiece.

A portable battery with AC is an excellent idea! Fairly sure Electric had you use something like this, which I'm all but certain this barebones outfit won't have, but I'll check. Not sure how they'll power their lights. I might buy a cheapo Amazon battery and pair it with a speaker. Hopefully it'll suffice since the car playback scenes are short.

u/Boostforlife97 · 2 pointsr/boostedboards

i got it for 140, it looks the same as this one. Kind of pricey but still cheaper than an XR and versatile for other uses.

u/stonewall1979 · 2 pointsr/SleepApnea

I don't use one. I camp with powered tent sites. I almost went this route last year but the site next to me let me run a line to my tent from their site. This was my back up plan if I hadn't been able to use their power. I had looked at a cpap battery back up a couple years ago and it was $500, the battery and inverter would have been $150. I know prices have come down since then and I was going to buy a battery bank as a CPAP backup, like this power bank but haven't needed to buy it. I liked the idea power inverter since it was multifunctional, but don't know how long it'll run my CPAP. I need to see how much my CPAP draws and run the calc to figure it all out.

u/Chaotic__Buddhist · 2 pointsr/mac

I've been using this:


Not to power a Mini, although I'm stealing that now. I use it to power radios in locations without A/C during emergencies.

You may want something larger, something different, but what you want exists. :)

Personally I think it is worth it, especially if you do what I did. I bought mine off ebay from bestbuy as an openbox, cost me 850ish dollars plus tax and an upgrade to next day shipping, which brought the total up to about $950.

mine came in perfect condition. You might not like this option, but it is a way to get it much cheaper. The sale price seems to change every so often

But despite the openbox, I was able to get the full premium plus warranty from dell for it for roughly 4 years (3 years 7 months or so, due to the fact it was openbox i believe.)


I think the ram should be upgraded however, and they do offer a 16gb ram openbox and new option from the bestbuy ebay store, and I am sure if you hunt around you will find an openbox at the bestbuy stores if you look.

If anything my ram was the only down side to this buy. But I intended to upgrade this anyhow and will be using crucial's compatibility guarantee program to make my purchase of 32gb of ram. This ram issue might not be a problem for you, however I run VM's for work and genuinely need the extra ram for things to actually run or the VM's have a high likelihood of not running or crashing.

I also dropped a 2 TB seagate firecuda hard-drive (SSHD) in my laptop with no problem ( I disabled UEFI secure boot and made sure the bios was up to date, and it worked perfectly on the first try). 96$ from amazon. I got probably 1tb worth of games on it already :P.

Going with an 8gb model gave me a few advantages as well, for example this laptop seems to come with dual sticks of ram no matter if you buy the 16gb or 8gb model. IF you want to upgrade to 32gb of ram, expect to throw away the old ram. Also the 8gb version came with a 256gb ssd, which is not a bad size and one less thing I have to worry about upgrading. Consider that I have used 98gb on my installation already...

So overall for my particular case, if I went with the 16gb version, in the matter of a month or two the following things would of happened.

I would of thrown out the ram, as I need the 32gb of ram and cannot reuse the old sticks in this particular latptop after an upgrade.

I would of thrown out the SSD, because just my base install I have done now would of ate all of the storage space. For reference I am using 98gb of ssd space, and have only 1 game installed on the ssd (csgo)

And I would of thrown out the HDD, because my base install has already used the entire storage space that drive would of provided. For reference I used about 1tb of storage already but I do have like most of my games installed (something like 47 games). I did that because I can lol, The other 1tb is dedicated to VM's and production related stuff.

Your end result might not be the same, if you are not intending to use it for the type of work like I do, and so you might have an advantage going with the 16GB model instead. Each person's usage and goals will differ.


There are some things to consider however

This thing does not have the ultimate battery life of like 10 hours you can find on other laptops.

I find that it lasts anywhere from 3~4 or so.

You cannot play games while on battery, at least not on anything close to high or medium settings without huge frame rate drops. And expect gaming to eat battery life much quicker.

I am saying this because, if you have never had a gaming laptop, you should be informed to expect this. My alienware had the same issue on both performance and battery life.

I did find a way to cheat this, by buying one of these.

it gave me at least an hour maybe hour and a half of gaming time, and I suspect it will give 4~8 more hours of normal web browsing usage but I haven't tried it fully yet. It can be very useful if you are mobile and need to use your laptop for production. However I don't think you can bring it on carry-on at an airport due to the restrictions of battery sizes by TSA, you should be able to put it in checked luggage however.

Other than the battery life, I personally cannot find too many cons about this laptop. It seems to be a solid performer overall, and has all the modern features you need like the fancy new thunderbolt connection (40Gbps), and support for NVME high speed drives as well as a regular 2.5" drive (as long as its 7mm or less in thickness) . And the build quality seems very good.

Its not very flashy and the cost to performance ratio is way up there. It has the amazing 10 series nvidia graphics card and ddr4 ram and the latest generation intel processor with an insane 12 cores and even turbo boosts on 6 cores up to something like 3.9 ghz which is pretty fast.

My only gripe would be with the battery life. however most laptops I have owned, especially gaming ones never had anything near 4 hours. It should be considered that I haven't purchased a laptop in about 2 years, so this point probably counts for nothing as I havent done all the research I can into battery life in newer laptops gaming or non gaming.


On a side note, here are a few few recommended accessories to protect your laptop no matter what you buy, its not a bad idea to get something like the following

Hardened glass screen protector


Water and dust Resistant keyboard cover to give me an extra step against a drop of water penetrating the keyboard and ruining the motherboard underneath.


It should be noted that I do not get paid for any of these items, you'll notice none of them are links to a compensated account somewhere.

I just like dell products and have had good experiences with them. This is just another case of a product that I think is great and worth the money.




u/grlonfire93 · 1 pointr/Survival

I was looking at this one. It's 3.3lbs, but like I said it's expensive

u/EliteAlmondMilk · 1 pointr/vandwellers

So what's the problem that I'll run into with a not-smart isolator just that it won't top off? I did read the alt+solar link but still trying to understand. Also is this one smart? Ty.

I don't have a roof rack so I'll probably just start with alt only and hope to add solar in the future. Also looking at getting this battery pack:

u/Noodle_Long_And_Soft · 1 pointr/WindowsMR

For a 22v(ish) lipo stepped down to 12V (for use with a laptop car charger), you would at minimum just have to buy a pack of automotive crimp connectors and a pre-soldered XT60 connnector, then just crimp on the 2+2 input+output wires on the buck converter. A low voltage buzzer would be good too.

(The reason it would probably be easiest to run 22V->12V->19V instead of just 22V->19V would just be for added protection from chinesium buck converters, swappable batteries, and not having to muck with charger-sensing circuitry with makes like Lenovo)

Although one of those laptop power banks or AC power banks would do the job just fine with a compatible lappy as well.
