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

When are you starting the campaign on indiegogo?

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

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.

@@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.

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?

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.

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.

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.

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)

@@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.

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

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.

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.

It is likely going to be 25000mAh also, if there is cost issues, I might have to use lower capacity batteries.

92.5Wh, so just under the 100Wh limit imposed by most airlines 5 x 3.7V 5Ah batteries in series 👍

Probably 21700 format cell like the Samsung 50E which has a 5000mAh rating
