Power bank Crowdfunding Campaign Video - (Campaign Link in the description)

[@kralyn3d]

Hello, the designer of the PolyCharge Power bank here. I wish you enjoyed this video showcasing this awesome idea. Please check out the Campaign Preview link: www.indiegogo.com/project/preview/0923bfd5 Website Link: www.kralyn.com Campaign Link: igg.me/at/polycharge

[@0ctober31st]

When are you starting the campaign on indiegogo?

[@jaxonsandwith502]

will the dc cord coming with the early bird bundle have a hot swappable tip/ connector

[@MojoPapiFPV]

I want you and this project to succeed but the pricing seems a bit steep even for early bird. You can get 25-27k mAh 100W PD packs for around $75. The Anker Powerhouse 200, 213Wh/57600mAh is $180 which is just $30 over the Poly std price. If you can get this between $80-$100 I think the campaign will do really well but for $130 it should probably include the AC adapter, obviously, I'm hoping you can still make a good profit and and recoup your investment at that price point as well.

[@Raress96]

@@MojoPapiFPV PowerHouse 200 is 260$, where did you get your pricing from?Also, that thing is huge, not targeted to the same audience. And this is not just a PD pack, it has the DC in/out port which honestly is the best thing about this, and not many other power banks have that. I agree that it should come with the AC adapter though, on the site it says 149$ for the power bank + AC, but on Indiego it's 129$ early bird for just the power bank, and the AC module is 35$, so that's 164$, which doesn't seem quite right. Probably the pricing on the site is wrong or something, I'm sure it's going to be updated after the campaign starts. Yeah, the price is high for the DIY community, but compared to commercial products at 200+$, I think the price is perfectly fine. The plans will also be released after the campaign ends, so you can build your own if you want to.

[@Tollyman69]

How does the expandable battery pack work when your main unit is dead and the expandable unit is charged. Does it charge the battery in the main unit or only power the USB? Also It appears that all the expansion modules are 3D printed enclosures, 3D printing at quantity scale is very time consuming. How do you plan to overcome this. What are your plans when you have to delever thousands of units? Do you have experience in global logistics/shipping to make sure there isn't any major delays?

[@caserolooo7917]

Duuuuuuuuuude, huge congrats This really was something the world needed I wish you the best luck on your campaign

[@Heidegaff]

This is the shit I like to see. Someone building his own stuff the way he wants it to be, taking his functioning prototype and mass producing it because it's good. Congrats lad.

[@adrianbonpin]

LETS GOOOO!! Advanced Congrats on the upcoming crowdfunding!

[@Raress96]

YES!Finally!Been waiting for this, can't wait to support you :)

[@eric8737]

This is a phenomenal idea. I do a lot of austere medical work in developing countries, and this hits all the right note for me for power in those types of areas. I just started following your channel (upsidedown 3d printer), and seeing the quality of your engineering design skill made it an easy decision to back the project (I got the optional modules as well). Can't wait to get it!

[@pherd-0884]

Hell Yes! I can't wait for the link to go live. I've been following this project since I first stumbled upon your channel. Lets do this!

[@cnckilla]

Dude, kickass design! I just finished up your first power bank video uploaded over a year ago. It's amazing to see how much progress you've made in that time. Keep it up!

[@tinkuzen]

My man finally , was waiting for it so long :) awesome

[@Mainlidar]

I have love your videos since you started your channel...wish you success

[@krismate4654]

Good to see you taking this to the next level man. Well done.

[@88NA]

finally the product is out

[@arnold19921]

Amazing. Congratulations to you 👏🏾👏🏾

[@ANBHK]

From building a DIY bottle sized multi charging device to this!! HUGE SUCCESS!! Being an enthusiast in electronics, I salute your hardwork and success. Keep this good work!!

[@socatekun]

Congrats for the campaign, since your previous video and talk regarding this powerbank I still haven't decide what to use for USB PD IC's microcontroller and battery's. Hope I can support your effort for this campaign.

[@fast-yi9js]

This is awesome, I'll make sure to share it around plenty on the 22rd. Its a shame you cant make kits yourself, but with a bit of luck there will be voron style kits before long, theres hoping at least xD

[@TRMrStone]

I wish the best and hope that this will be a success! :D

[@34Gw]

Omg You really succeed! Congratulations))

[@keatodylan]

Should see if Dave from EEVBlog will take a look at it!

[@fmgomez518]

Congratulations, been a fan since the first power bank. This is truly awesome. Again congratulations!

[@zonetwelve5881]

I miss the campaign, but I still will wait for this can be shop. hope you can keep doing that.

[@Moose254]

We have been supporting you from the beginning and you haven't let any of us down... Great Job man 💯 🔥

[@-indeed8285]

Go Ahead. Thank you so much for making it open source. 🇧🇩

[@tonieronvaldez]

Dream comes true your invented your own creation dude try keep up

[@DavidRodriguez-df4gt]

Sweet commercial! I hope this project font the success it deserves

[@3DPrismaPrint]

You did, congratulations bro ❤ 🎉 👍🏼

[@MrNoipe]

I would love to know how durable the product is from drops and splashes, and if the lithium batteries inside are replaceable. Good work on launching!

[@angst_]

It's "open source", but I too would like to know if it's easily opened and serviced. My last power bank had a single cell fail and I had to destroy it to open it.

[@Botio]

YES!!! took the fancy light out!! good move! Love this and I want to have one of this to review on my channel

[@AlexHuebi]

Its been quite some time, and I am sad that it didn’t get funded. But are you still planning to release the schematics?

[@CraftClone1]

Congrats! I was hyped before the video and now I cant wait to buy it!! Best of luck :)

[@Dashrendar2507]

That sounds absolutely awesome. Congrats on the design!

[@engineer0239]

I'm wondering how the battery module works... For me the swappable Lithium ion battery pack was always the best feature of your Powerbanks. Can you attach a battery module and keep charging, even if the battery in the main housing is empty?

[@maxleon1721]

Man, I did not get a notification for this video. I would have jump on that campain without a second thought.

[@Divyesh_Sinha]

Your website says it can charge a Macbook pro 4.5 Times Your Powerbank is 92.5Whr Considering its 95% Efficiency Usable capacity is 87.8whr at the 100W PD port A Macbook battery is of 57.1whr(5152mah X 11.1v, from your website example) so 87.8/57.1= 1.5 Times Which wayyy far from the 4.5 times claim So.....can you explain this? What I am Assuming you did is Took 25000mah multiplied it 93% efficiency 25000mah X 0.93 = 23,250mah 23250/5152 = 4.5 Times But you missed that the laptop has 3 of 5152mah cells That makes it a 15456mah battery

[@abidhussain9229]

This is the amazing power bank i have ever seen. Good job. 👍

[@Scott_C]

Seems magical!

[@julians.3995]

holy shit the video looks way better than i expected, well done. just one question will the pcb scematics be released like your previous powerbank or do i have to buy one wait 1.5 years and then take i apart, since all i want is the pcb you designed to build my own powerbank?

[@kralyn3d]

PCB schematics will be released when the production run is finished, since changes might have to be made based on Chip availability (there is a global chip shortage) functions will be the same though.

[@Ohlookitsajosh]

Congratulations my friend!! Best of luck to you! I think I may still build one of your older models and make my own custom power bank 😋

[@docgriff86]

Yo! Where can I buy one of these?!? I missed the campaign by a year, but would love to give you my money for one!!

[@강강우쨧떼]

His indiegogo campaign did not reached its goal. He said he might release the design in future, but it's been a year and I don't think it's going happen any time soon. Such a shame that we won't be able to buy this wonderful powerbank.

[@Creative_Electronics]

This is insane 👍🏻👍🏻

[@hugo-4715]

It's cool but a bit expensive for a power bank. I'm waiting for a smaller and cheaper one but it's reallly cool looking!

[@mohdrizuan8478]

congratulation broo..... great to see from various prototype to an actual product... wish u a great future ahead...

[@nikolasedlar7777]

I would love to have a diy version so I can make it myself :) Do you plan relasing schematics and other materials as opensource when your campaign ends ?

[@Raress96]

It is stated on the Indigogo page that they plans will be shared after campaign end. He didn't share them before so other companies don't copy the idea.

[@makory5675]

Hello @Kralyn3d Glad your powerbank project culminating to this! I was wondering if you later on could consider offering a Pcb only for the person who own 3d printer as it would lower the cost and shipping! Regards

[@keepsonic5759]

I'm very Sorry for the campaign... Did you plan to create another one or you put this project open source like the previous one? I'm very sad... I would like to build this and I don't want see this project forget because it has a lot of potential!

[@TurboSqu1d]

YEEEEEEESSSSS! Finally!

[@freshios4873]

I hate how there are sooo many power banks out there yet this is the most efficient one I've ever seen, and people think the ones they have are good enough.. I think this one should be the industry standard. A Little too expensive for me but I'd still recommend it

[@Raress96]

Yeah, seems expensive compared to DIY stuff, but compared to what is on the market, it's actually a really good value and offers features that other don't have.

[@jacobkaltz1958]

This is going to be sooooo sick!!👏

[@pdadey]

Congratulations on the launch! Can the led be programmed to display the day/time?

[@DArkwIng2]

the campain is closed. are you able to open it again at some point? would love to see this on the market

[@teddysibuyi4148]

congrats man. lots of success to you.

[@peppelorum]

Wow! Well done! Of course I will back it!

[@idzhoni]

Я бы купил себе такой, когда увидел в видео тему про модуля - подумал, было бы неплохо модуль с солнечной батарей. А потом увидел что можно подключать так. Очень удобно, мне бы модель с розеткой в 220 вольт

[@MasterOfGigs]

Will it be available for sale again? The Crowdfunding campaign has unfortunately already ended

[@Mallampati4]

Hey, I just got a refund from Indiegogo for the power bank - is the campaign cancelled? Would be really bummed if that's the case!

[@LastNameInTown]

Wow such a great update! The name is great and a really nice and very professional Campaign vid, I am very interested. Photographers and Videographers will love the AC adaptor. 1 question, will the AC be available for Aus/NZ 240v?

[@jaxonsandwith502]

the eu model ac adapter is universal with all 220 volt plugs also i am also from aus

[@burnzy56469]

I really want to buy one and put my own 18650 batteries in it. Thanks for all the hard work

[@kostyp5489]

Finally a good power bank!!! Take my money, I want one!

[@lightning7546]

Nice, good luck with the campaign, because i would buy one, but i don't have money : )

[@chetanshintre7355]

I think there is some mistake in calculating power bank capacity. As batteries are connected in series the capacity does not increase and remains the same that is 5000mah. So, the total power bank capacity is 5000mah and not 20,000mah.

[@engineer0239]

It would be 25000mah if it was only 1S. Even if thats not true every commercial smartphone or Powerbank is specified that way for easier comparison (although Wh would work fine as well)

[@chetanshintre7355]

@@engineer0239 As you said it would be 25000mah if it was only 1S but in this case they are connected 5s1p configuration. And speaking of other power bank with less or no fast charging facility, the power bank batteries are connected in parallel to achieve that capacity.

[@dennisolsson3119]

Would be interesting with a version sans batteries... For ease of shipping, toll and if someone would like to tweak the capacity from the beginning.

[@tdg9281]

Hey ! would it be possible to make an european plug module instead of the american one ? Thanks !

[@trolynut]

Can't wait

[@radekt.7843]

I looked at your channel once every month or soo to see if you posted update for your promissed powerbank.. and I guess I missed it by a month :c im mad ta myself for that... :c

[@kelvinadams1749]

Pls can u make video on how to build it And leave a link for us to buy the powerbank board

[@ZipZash]

Looks fantastic!

[@ahmadmahmoodi2124]

very good Like the previous versions, is not open source ?. I want to make it myself and enjoy the montage

[@unsopken0623]

Finally Congratulations

[@randominternetdude6]

What is the highest voltage the adjustable DC port can output ?

[@angst_]

Myself 1000 lumen handheld flashlight gets pretty hot on max brightness. I could imagine a 5000 lumen 25w light might be 5 times worse. What are some of the things you're doing to address overheating? Is the light 100% duty cycle? ("up to 10 hours" ) Or will it overheat and turn off? Thanks!

[@ngwai3723]

Great work bro Big fan

[@dr_epic_gusta5714]

Finaly!!!!

[@imtryingmusic3509]

So excited for this

[@Mainlidar]

Hey kralyn you haven't posted the campaign it's in draft mode so we can't see it when we click on the link you provided..

[@kralyn3d]

Use the preview link

[@WaschyNumber1]

Cool 👍🖖

[@szeligus]

Looks good. I think I'm gonna buy one

[@F76986jhg]

Very nice bro❤️🇧🇷!

[@iblackfeathers]

00:29 i just noticed that on your indiegogo photo of the ac plug accessory and on this video that the ac plug has the bigger blade/prong on the right instead of on the left. why is that? first i thought it was a mirror image, but it appears consistent on the video. the smaller plug is typically on the right prong not left.

[@jaysonhernandez6728]

Congrats! Is this still a 3d printed or it will be an injection molded plastic?

[@sheedyaja6465]

Should be injected mold, 3d printed will be hard to qc and produce

[@jasper5945]

Will the final case be 3d printed? or injection molded? anyway great stuff!!!

[@kralyn3d]

The main power bank will be injection molded, but the modules will be 3D printer(low volume)

[@ValFPV]

How much current does the DC output support? Enough for 19V 7A (133W)?

[@beingspectator3764]

Congratulations 🥳🥳

[@Natorsigth]

The only thing I can think it lacks of is the ability to start cars like jumpers, maybe with a module you can do that

[@leaaron9901]

Yeah 😉😉😉

[@lifeai1889]

where can i get details about how to build it like code and 3d file, part list i checked all links in the discryption but still cant find it

Hey man its nearly a year since it started there is no update on its progress Can u just give us an update

[@mlgoverrated745]

I really hope to buy one!

[@Raress96]

Hm, the campaign seems to be going really slowly, maybe more marketing is needed. I really hope that the goal is reached since I am excited to try this.

Sir make a video on making of voltage and amperage meter

[@Mainlidar]

Hope this won't affect the open source diy projects videos you make... because i love watching diy projects from you

As this unfortunately didn't make it to the market, can you publish the designs somewhere?

[@hfhfdjsk]

Consider a scroll wheel interface like ISDT chargers!

[@dengdeng2760]

Great Video,I have new design VRURC fast charging 20000mah power bank built in multi cables ,could you help do a video?

[@gnorbsl4194]

Your website says 20k mAh and 25k mAh, the campaign says 25k mAh, which one is it? and do you have plans to offer EU sockets?

[@kralyn3d]

If that is the case, I will fix the mistake, it is 25K mAh. I do offer EU AC modules.

[@Raress96]

Is the pass through charging limited to 60W also?For example, I am using the DC output port to output 100W, will I be able to charge through USBC only at 60W?

[@kralyn3d]

The battery can be safely charged at 60W so the pass through charging is limited at this. I might able to increase the pass through charging current via software, but I have not tested this yet.

[@Raress96]

Will there be a way to limit the charging current ourselves, to prolong battery life if for example we don't need the fast charging every time?

[@kralyn3d]

@@Raress96 I am certain this feature can be added in firmware, Ill note this down.
