How is this different from a regular lithium-ion power bank?
Traditional Lithium ion batteries push charge through a flammable liquid. We’ve swapped almost all of that liquid for a solid oxide layer—about 97.5% solid, 2.5 % liquid, so there’s far less to leak or ignite. Paired with advanced cathode and anode materials, the pack stores roughly twice the energy of typical safer chemistries while staying cool even if punctured or crushed.

So is it solid-state or semi-solid?
Technically it’s semi-solid: the electrolyte is mostly solid oxide with a tiny amount of liquid still inside. Because that liquid fraction is so small, the cell delivers the key solid-state safety benefit, heat can’t spread and ignite, while still charging and discharging quickly.

Why isn’t this chemistry inside everyday smartphones yet?
Phones have far less room for protective layers, and their batteries are produced at enormous scale. The precise tolerances and extra cost of semi-solid cells make them better suited to power banks first, where there’s more space and volume is lower. As production techniques mature, you’ll see the tech migrate into thinner devices.

Can you explain, without the jargon, how your solid-state batteries work
Picture a layered sandwich: • Cathode (NMC sulfide) on one side stores energy. • Anode (nanoporous silicon-carbide) on the other stores more energy. • A solid oxide electrolyte sits between them and lets lithium ions shuttle back and forth during charge and discharge. Because the electrolyte is nearly solid, even if the pack is punctured the heat can’t pool enough to ignite, yet the ions still move fast enough for stable 2 C charging and discharging.

Does it support Qi2 wireless charging?
We’re building the power bank to meet the full Qi2 15 W magnetic charging spec. Our hardware already hits those electrical requirements, but the official Qi2 certification process is still underway. Until that paperwork is complete, you’ll see us describe the feature as 15 W magnetic wireless charging. Barring any last-minute hiccups in testing, the units that ship to backers will carry the Qi2 logo.

Which certifications are you securing, and when will they be finished?
UN 38.3, IEC 62133-2 / CB, Qi2, FCC Part 15, CE, UKCA, UL 2054 & 62368-1, 3C, and RCM are all in testing now and will be fully certified before the first production units leave the factory.

Can I fly with it?
Yes. Both the 5 K and 10 K packs are well under the 100 Wh limit that airlines allow in carry-on bags. We’re finishing UN 38.3 testing now and will add the report to our press folder once the lab signs off. Aviation safety committees are actively evaluating solid-state cells like ours as a lower-risk alternative to conventional lithium-ion, so you’ll likely see this chemistry welcomed on flights for years to come.

Does it support pass-through charging (charge the pack and a phone at the same time)?
Yes. Both USB-C and magnetic wireless outputs remain active while the pack itself is being recharged.

How long will the battery last before capacity drops?
Our latest cycle-life tests show the pack holds 80 % of its original capacity after about 1 000 full charge cycles, roughly three years of daily use

How many full phone charges will I get?
Final numbers depend on the model you choose (5 K or 10 K). We’ll share exact runtimes once testing and firmware are finalized.

Why do some of the GIFs show a pixel-style display instead of the color screen?
Those shots use early pre-production shells. The engineering samples only had a simple segmented display so we could validate charging logic. Final production units will ship with the full-color LCD that shows remaining capacity, live wattage in/out, and charging status.

Does the magnetic wireless charger work with non-iPhones (Android/Pixel, etc.)?
Yes. Any phone that supports Qi or Qi2 and can hold a MagSafe-style ring will attach and charge.

What is Kickstarter?
Kickstarter is a launchpad for creators to raise funds for the initial production of their invention. Backers (that’s you!) can support the creator by pre-ordering the product at a discounted price.

What does it mean to back a project (pledge)?
When you back a project, you’re pre-ordering the product. That means you’ll get it once it’s produced. Besides getting the product itself, you’re also joining a community. Follow along the production process, take part in important surveys and give the creator valuable feedback.

How do I pledge?
In order to pledge, click that green button that says “Back this project”. You’ll get to select your shipping country and choose your desired pledge level and reward.

When is my money collected?
Your money will be collected only after the project ends on DAY, MONTH DAYOFMONTH, 2025. If the project is cancelled for any reason, you won’t be charged.

What payment methods can I use?
You can use any debit or credit card associated with Visa, Mastercard or American Express, as well as Discover and JCB cards. Kickstarter does not accept payments with PayPal.

When will I get my pre-order?
The SolidSafe Lineup is expected to ship in September. Depending on your location, you’ll get them sometime between September - Early October. Please note that this is an estimate, as you’re pre-ordering the product and production delays could arise.

What is BackerKit?
BackerKit is a service that crowdfunded project creators use to keep track of hundreds to tens of thousands of backers—from shipping details, pledge levels, preferences and quantities, whether they have paid or had their card declined, special notes, and everything in between!
The BackerKit software and support team is independent from the campaign’s project team—BackerKit does not handle the actual reward shipping. For more information about the preparation or delivery status of your rewards, please check the project's updates page.
How does BackerKit work?
After the campaign ends, the project creator will send you an email with a unique link to your survey. You can check out a walkthrough of the process here.
I never received my invitation. How do I complete the survey?
The most common reasons for not receiving a survey email is that you may be checking an email inbox different from the email address you used to sign up with Kickstarter, Indiegogo or Tilt Pro account, or it may be caught in your spam filter.
Confirm that the email address you are searching matches the email address tied to your Kickstarter, Indiegogo, or Tilt Pro account. If that doesn’t work, then try checking your spam, junk or promotions folders. You can also search for "backerkit” in your inbox.
To resend the survey to yourself, visit the project page and input the email address associated with your Kickstarter, Indiegogo or Tilt Pro account.
How do I update my shipping address?
BackerKit allows you to update your shipping address until the shipping addresses are locked by the project creator. To update your address, go back to your BackerKit survey by inputting your email here.
When will my order be shipped, charged or locked?
That is handled directly by the project creator. BackerKit functions independently of the project itself, so we do not have control of their physical shipping timeline. If you want to check on the project’s status, we recommend reading over the project's updates page.
I completed the survey, but haven't received my rewards yet. When will they arrive?
As BackerKit does not actually handle any rewards or shipping, the best way to stay updated on the shipping timeline would be to check out the project's updates page.
