FAQ
Is the SolidSafe™ Air power bank allowed on airplanes?
Yes. Every SolidSafe™ power bank meets TSA power bank regulations and is airline-approved for carry-on travel. Each model is rated below the 100 Wh limit, making it safe to bring on domestic and international flights. Always check with your individual airline since power bank travel rules can vary as policies evolve. The solid-state battery designadds extra safety and stability compared to traditional lithium-ion packs, making SolidSafe™ one of the safest power banks for air travel.
How is the solid-state design of SolidSafe™ Air different from traditional lithium-ion power banks?
Most power banks today use lithium-ion or lithium-polymer battery cells filled with a flammable liquid electrolyte. When those cells overheat or get damaged, that liquid can react under pressure and cause fires or explosions.
SolidSafe™ uses a semi-solid-state cell, not a traditional liquid one. The liquid content is reduced to about 2.5%, replaced with a gel-like electrolyte that stays cool and stable. This chemistry resists heat and impact, greatly lowering the risk of cell fires while improving long-term performance. It’s been tested against drills, nails, and cuts that would destroy a normal pack.
The result is a safer, cooler, and more reliable solid-state power bank that delivers consistent power without the dangers of older lithium design
Does the SolidSafe™ Air support wireless charging, MagSafe, or Qi2?
Yes. SolidSafe is built on the Qi2 magnetic wireless standard, delivering up to 15W fast wireless charging for MagSafe-compatible iPhones and Qi2 Android devices like the Google Pixel 9 Pro and Samsung Galaxy S25. The magnets align precisely for a perfect snap and an efficient, stable charge every time.
It’s a wireless portable charger that works across both ecosystems, letting you power your iPhone, Android, or wireless earbuds without cables. Whether you’re at your desk, on a flight, or traveling abroad, SolidSafe is the go-to Qi2 magnetic power bank for anyone who needs a compact, reliable, and fast wireless power bank.
What devices can I charge with the SolidSafe™ 10K?
SolidSafe 5K charges phones, tablets, cameras, and earbuds via Qi2 magnetic wireless charging up to 15 W and USB-C Power Delivery up to 20W. It wirelessly charges MagSafe iPhones and Qi2 Androids like Google Pixel 9 Pro and Samsung Galaxy S25, and it charges AirPods and Galaxy Buds. The USB-C port delivers 20 W fast charging for iPhone 17, iPhone 16, iPad, and most Android phones and tablets that support PD 20 W.
Does the SolidSafe™ Air support pass-through charging?
Yes. SolidSafe Air 5K supports pass-through charging, letting you charge the power bank and your device at the same time through USB-C Power Delivery. You can plug in your phone, tablet, or earbuds while the SolidSafe recharges. The solid-state battery is built for safe, efficient charging, making it a dependable portable power bank for travel and everyday use.
Can I use any charger or cable with SolidSafe?
Yes. SolidSafe Air 5K includes a 60 W USB-C cable, which is the best way to recharge it quickly and safely. You can also use most USB-C cables and wall chargers that support Power Delivery (PD) above 20 W. The SolidSafe Air 5K accepts up to 15 W PD input, so any PD-rated charger from 20 W – 65 W will work perfectly.
Avoid very low-power USB-A or non-PD chargers, as they’ll charge slowly. For best results, use a USB-C PD wall charger (30 W or higher) with a certified USB-C to USB-C cable.
How long does it take to recharge the SolidSafe™ 5K?
SolidSafe 5K recharges through its15W USB-C PD input. Using the included 60 W USB-C cable and a PD wall charger rated 20 W or higher, it reaches about 80% charge in roughly one hour and a full charge soon after. The higher-rated charger doesn’t overcharge the battery, it simply provides stable 15W delivery for faster, consistent charging
Where do you ship and how long does it take?
We currently ship SolidSafe products within the United States with free standard shipping on all orders. Most orders are processed within two business days, and delivery times vary by location. Once your order ships, you’ll receive a tracking link so you can follow it all the way to your door.
What’s the warranty on SolidSafe Air?
SolidSafe products are covered by a 2-year limited warranty that protects against manufacturing defects and performance issues under normal use. If something goes wrong within that period, our support team will help repair or replace your unit. Full warranty terms are included with every product and available upon request.
I hear a buzzing noise when wireless charging. Is that normal?
That's the charging coil at work. All wireless chargers produce a faint hum when transferring energy magnetically. It can be more noticeable when your battery is low (the coil works harder to deliver power) and when the charger is this thin (less material between the coil and your ears). It fades as your phone fills up. Totally normal, and it has zero effect on charging speed, battery health, or safety.
