Reddit reviews Anker Powerhouse, Compact 400Wh / 120000mAh Portable Outlet, Generator Alternative Rechargeable Power Source with Silent DC/AC Inverter, 12V Car/AC/USB Outputs for Camping, CPAP or Emergency Backup

It's on Amazon for $499 but its currently unavailable.

Then you should see the 120k mAh Anker PowerHouse.

Remember folks, the battery is literally the stomach of your moeblob. Battery stress will be directly voiced as stomach problems, so avoid stressing your moeblob with deep charge cycles and rapid charging; carelessly crashing below 30% is just really rude anyway. Make sure she's relaxed and cool before and during charging. If she's a brainy one, ensure she's not overthinking anything as that alone will heat her up.

Use a high-quality charger and/or cable with a good powerline filter/power surge protector. I like to use ones from Anker. If you have to feed her on the go, I recommend this right here. This will provide her with tons of clean, tasty power.

When it comes time to replace her battery, ensure you can get a replacement from her manufacturer, or an OE equivalent from a reputable company such as LG, Panasonic, Sanyo, or Duracell. You might also want to look into Li-Fe batteries as the lithium-iron phosphate chemical is a lot more stable and has 4x the number of charge cycles. Unfortunately, the Li-Fe batteries aren't as compact and don't have the same voltage as Li-On batteries, so I can only run these in my two larger moeblobs that can compensate for the voltage. They tell me all sorts of good things though, especially that they aren't exhausted and as ravenously hungry, even when being feisty at 20%.

I hope I helped someone. All of these tips will prevent your precious moeblob from being BURNED ALIVE IN A MOLTEN BALL OF LITHIUM ION FIRE

Usually they'll have one of those small honda generators. They're really quiet. You're not supposed to have generators in GA, IIRC, but lol rules. They're hot items for theft too, so be careful.

Alternatively, I've seen people use the power packs like for car emergencies that have the regular plug outlets. They'll die pretty quickly with continuous use, so sometimes people bring a fee, but they're easily $100 each(example: https://www.amazon.com/dp/B07FYJVFNK/ref=cm_sw_r_cp_apa_i_LemSCb8F83D33) . They take forever to recharge, so it's not likely you'll be able to do it at the park. Or you can get this beast: https://www.amazon.com/dp/B0196GQAKM/ref=cm_sw_r_cp_apa_i_1bmSCbK96YA6M

The real LPT is engineering a deep cycle battery into a custom made box. Like this: https://www.arkportablepower.com/blogs/news/48712645-cool-diy-battery-box-on-reddit

Most these crews have this stuff laying around from hunting/camping/fishing/etc. So the investment curve is steep for strictly festivals.

Yes, When I had my EV I would drive under 50 miles almost every day.

Regarding the product i couldn't find a data sheet or specifications on your website.

That said from photos, and comments here, it appears to be a 5kWh external battery pack, able to be charged from a standard wall outlet (using a tiny wall wart), and with an integrated inverter powerful enough to run a factory volt EVSE (I assume something like 15A at 110V?)

Your website shows a slim female carrying the device with one hand, and you advertise the price as USD999. You state on reddit the current charge time from a wall outlet is 6 hours.

There are a few technical issues with the above that you really should look into.

Weight As an example, the chevy bolt battery pack holds 60kWh, and weights 440kg. Your pack is to be 12 times smaller, so weight will be at least 37 kg (prob more as packaging in a smaller pack will be less efficient. A 2kW inverter will be 5 - 8 kg, therefore your minimum weight will be 42 - 45kg's. No way your slim female is carrying that with one hand wearing heels.

Cost A 6.4kWh powerwall runs as USD3000. Your price is under a third of that, and you need to include an inverter & charger that will run to hundreds of dollars...

Wall Wart To charge in 6 hours, you will need to charge at 830Watts. I don't think any wall wart goes that high.

-------------------------------------------------

Take a look at what is already on the market:

0.4kWh, 300W output battery bank for USD390, 12.36 pounds

Anker 0.4kWh, USD500, 9.36 pounds

1.1kWh, 1100W output, USD1,749, 20 pounds

You specs require something about 10 to 12 times the capacity / inverter power as the first two items, and about 5 times the capacity / inverter power of the last one.

As such I would expect you would need to price your device at around USD 6000, and expect it to weigh 100pounds (roughly 50kg).

With those numbers the proposal is a lot less attractive. 50kg's is very hard to move by hand, and $6000 is a lot of money to tie up in a battery bank. (I wouldn't want to leave that unattended as I charged during the day). Also that money would go a long way in terms of just buying a longer range EV in the first place (Price jump from a 30kWh Leaf to a 60kWh Chevy Bolt in the USA is $6000) and that buys you a 6x the additional range of your 5kWh power pack, with convenance to boot... (no charging car and power pack each night (just charge car), no lugging around heavy power pack. no need to change except at night (every second night) for your 40/ 50 mile days)...

This is one of the larger sizes that Anker makes.

Seems really damn solid and reliable. However, I haven't used it before. Expensive too. About 15 laptop charges, might be overkill for you if it's only for the weekend.

This is not the cheapest option, just the best known one.

Apparently you can charge it with a 120 w solar panel (16-17 volt, 8 Amp). See the questions at: https://www.amazon.com/Anker-Powerhouse-120000mAh-Alternative-Rechargeable/dp/B0196GQAKM

I just got a Anker Powerhouse (https://www.amazon.com/Anker-PowerHouse-Generator-Alternative-Rechargeable/dp/B0196GQAKM/ref=sr_1_2?ie=UTF8&qid=1493417945&sr=8-2&keywords=anker+powerhouse). It is expensive but good for all sorts of emergency power. I can run a full night with the humidifier on, or multiple nights without. I was considering the deep cycle marine battery and all in the DYI ideas, but chose something more expensive, but more flexible.

Someone above posted about the goal zero, its a great product! for the budget savy person, i went with a cheaper route that i keep in my van that keeps me running smoothly on my weekend shoots granted i shoot motorsports, but it keep my laptop charged, battery packs, audio equipment, phone and gimbals all charged up. its the Anker powerhouse, decent price and its on sale, lightweight enough to take with me if needed, and its dead quiet check it out. https://www.amazon.com/Anker-PowerHouse-Generator-Alternative-Rechargeable/dp/B0196GQAKM

I've been intrigued by the goal zero generators for a while, but then I found this. Seems to be significantly more powerful for the same price, still has solar inputs. I do lots of car camping and am really considering something like this eventually.

not sure what the recharge rate is but i would imagine unless your directly tethering to the terminals then you would be limited to the fuse amperage, typically like 15 amps on a cigarette plug i think?


back on the main topic, maybe something in this article might help? https://teslatap.com/articles/12-volt-battery-compendium/ they dont mention exact rates that i saw but it says "

>The Gen 2 DC-DC converter in the refreshed Model S accepts 220 to 430 VDC at 15 amps, and outputs 9 to 16 VDC. When outputting 12 VDC, it can deliver about 200 amps.
>
>The Model 3 integrates the charger and the DC-DC converter into a single package, the PCS (Power Conversion System)

​

IMHO i would just invest in one of those Portable power stations from the likes of Jackery, Anker or Goal Zero especially seeing as how the replacement battery is going for about $500 on Amazon.

Enjoy

Not cheap but should meet your needs. Option 1 Option 2

Probably the easiest way to quickly get going is to get something like this: https://www.amazon.com/Anker-PowerHouse-Generator-Alternative-Rechargeable/dp/B0196GQAKM

I know it costs a lot.. but if you can get paid 50usd/second for the timelapses, it is probably easiest way ! Probably runs a D700 for at least a week. This is of course if you cannot get an extension cord there. With an extension cord or even the Anker PowerHouse, you could use something like this too: http://www.ebay.com/itm/AC-power-adapter-f-Nikon-D90-D300-D700-D3000-D5000-as-EH-5-EH-5A-EP-5-coupler-/180952806542

50Ah is old hat nowadays. Even Anker themselves sells a 120Ah powerbank these days, and that's on the low end of the scale.

https://www.amazon.com/Anker-PowerHouse-Generator-Alternative-Rechargeable/dp/B0196GQAKM

This may do the trick......... :D

Well I hate to burst your bubble but I live in the most expensive neighborhood in the city limits (Old West Austin - 78703) and we haven't had power for about 27 hours as well. God bless Anker

That can easily be solved with duct tape and a 120000 mah battery.

The gopro becomes slightly more unwieldy if you wanted to carry it in your bike helmet.

Not much different from https://www.amazon.com/Anker-PowerHouse-Generator-Alternative-Rechargeable/dp/B0196GQAKM though, and it's actually smaller for a higher price.

I suggest the Anker Powerhouse. It should suit all your needs because its made for outdoor camping or as an emergency portable power bank.

https://www.amazon.com/Anker-PowerHouse-120000mAh-Alternative-Rechargeable/dp/B0196GQAKM

Get this instead. haha https://smile.amazon.com/Anker-PowerHouse-Generator-Alternative-Rechargeable/dp/B0196GQAKM?sa-no-redirect=1

Something like this?

https://www.amazon.com/Anker-Powerhouse-120000mAh-Alternative-Rechargeable/dp/B0196GQAKM

This might be more in your range. I caught it for $180 on sale. Normal price is ~$220. It can run my laptop for a total of 20-25 hours. Granted, my laptop draws 9W from its internal battery under max load. I purchased it specifically for its low power consumption. If your laptop is running anything serious, you'd be looking at quite a bit less on-time.

When I first got it, I used it Saturday through Wednesday after work as my laptop's only power source until it died, running off my laptop's AC adapter. I'd probably get more out of it with a DC-DC car charger instead.

There's also this guy for $170, but it's half the capacity of the Suaoki.

You might also want to consider other things, like portable phone power banks. Ravpower's 34WH banks are $15 on sale and $20 full price. If you picked up 2-3 of those, a cheap usb powered tablet, and some usb string lights, you'd still come out under $150 if you picked up the tablet used from eBay.

And for $500, there's also the 400WH Anker PowerHouse.

You can charge it with this USB power bank that came out in May:

I would have made use of this battery.

Use only portable electronics when absolutely necessary.
