Features

  • WORLD'S THINNEST SEMI-SOLID-STATE 5,000MAH: At just 6.8mm at its thinnest point, the Air is the slimmest semi-solid-state Qi2 power bank you can buy the semi-solid-state design supports this slim form factor while helping the cells stay stable and reducing fire risk. It sits flush against your iPhone and slips into a pocket, slim bag or clutch. TechRadar Pro CES 2026 Picks Award Winner.
  • SEMI-SOLID-STATE SAFETY, BUILT FOR TRAVEL: Unlike conventional lithium-ion banks with a flammable liquid electrolyte, SolidSafe Air's semi-solid-state cells sharply cut the liquid component lowering risk at the cell level and staying stable under heat, stress and impact. It's not a circuit-only fix but a fundamental change in chemistry. At 18.5Wh, it's airline carry-on ready.
  • 15W QI2 MAGNETIC + 20W USB-C: Qi2-certified, MagSafe-compatible magnetic charging snaps onto iPhone 17, 16, 15, 14, 13 and 12 with precise, secure alignment, while the USB-C port delivers up to 20W when you're in a hurry. The 5,000mAh cell gives a modern iPhone roughly one full top-up, and you can charge wired and wireless at the same time.
  • TITANIUM SHELL, BUILT TO LAST: A titanium-reinforced shell resists dents and drops, and titanium's high thermal conductivity helps draw heat away from the cells and dissipate it at the surface during charging. It's premium protection that keeps the Air tough and travel-ready in a remarkably slim form.
  • CCC CERTIFIED FOR TRAVEL: CCC certified for battery compliance and travel in China, with FCC, CE and UKCA listings for other regions. Built-in circuit safeguards cover overcharge, over-discharge, overcurrent and short circuits. Magnetic charging suits MagSafe iPhones or a thin compatible case; for Pixel and other Android phones, use a magnetic case or the 20W USB-C port.

Description

In 2025, over 1.6 million power banks were recalled for fire hazards. The problem isn't one brand—it's the chemistry. Lithium-ion batteries contain flammable liquid electrolyte. SolidSafe eliminates the root cause with solid-state technology—designed to reduce fire risk at the cell level. Every product, every detail, every decision — sweated over. Whether you’re using it, sharing it, or building it with us, you’re part of something we put everything into. We know trust isn’t given. We’re here to earn it. That’s what BMX stands for: Better Mobile Xperience. Three letters shaped into a mark, built to carry everything we believe.

  • Great product
Color: Silver
I really like this power bank. It’s surprisingly thin, so it doesn’t make my phone feel bulky, and the magnetic connection is solid. It charges quickly, fits easily in my pocket, and has been great to have when I’m out for the day. Definitely a purchase I’m happy with.

  • Thin enough to actually keep on your phone
I love how slim it is. With the pack attached my phone still fits in my front pocket without feeling like a brick, which is more than I can say for other magnetic packs I've tried. Magnets are strong, it doesn't slide around or pop off in my pocket. Wireless charging is faster than I expected and it tops my phone up quickly when I need it. Light enough that I forget it's there. Looks good too, it's a clean design that doesn't stick out on the back of the phone. No complaints so far. Would buy again. ... show more

  • Very slim, powerful. Can get hot while in use.
Color: Gold
Gift for my wife. She likes it because it is so thin it will slide into her smallest purse almost like a credit card which none of the others will do. In fact, she can use her table top phone holder with it attached. Very powerful wireless charger, but also gets hot if she uses her iphone while charging. That is probably a down side for being so small - less area to cool while being used. Don't forget to turn on... unlike many chargers, it doesn't come on by itself (I don't know about most wireless chargers, I only know about wired ones). Much higher capacity than the ones that plug in at the bottom of the phone, and more convenient. We both appreciate the greater safety as a result of being a solid/semi-solid state battery. ... show more

  • Best quality power bank I’ve had
I got this for my wife because her phone is constantly running out of battery, and we love it! Super sleek looking! You can tell it’s high quality. And most importantly, it works great! We love it. This is the second one we get. They changed the design, so it’s slimmer. Normally we don’t do reviews, but this one impressed me. Since it’s so slim, and light I can just take it everywhere in my pocket. Great price for the quality. Thanks guys! I’ll order more for Christmas gifts 😄 ... show more

  • Thin, good build, but no cigar!
Color: Gold
This unit was really slim and had a high quality build, in my own use, it wasn't able to charge my Pixel 10 pro XL enough to have been 5k mwh. Recharging rate was only 18w. If you're tight on space and want just an emergency power pack, this would be a good fit. Not otherwise.

  • Poor Quality, noisy, hot.
Color: Gold
First battery pack I’ve ever had that emits a high pitched whining noise, logo is printed crooked, gets very hot, overall pretty bad, just skip it I’m sure you can find similar items on the internet for less money.

  • This is my second BMX battery and it won't be my last
There are several things to understand about this battery. First, it is thin, and I mean this is the thinnest battery I've ever seen. It is less than half the thickness of my Mophie battery even when taking the Mophie's stand out of the equation. Second. Because of how thin it is, it feels great on the phone, almost invisible. Third, Despite how thin it is, it feels incredibly robust. Way more solid than I expected. Fourth, I am a fan of BMX batteries because they are solid state batteries, which means they charge and recharge faster and aren't prone to fires or overheating when old or damaged like standard lithium batteries. I bought this one because I already own a BMX 10,000mAh battery which I picked up from their CES booth earlier this year that I've used a ton. That said, I think this is my new favorite battery and it's going with me everywhere. ... show more

  • Practical and Useful!
I’ve tried a few magnetic power banks before, and while they all worked fine, they usually made my phone so bulky that I ended up taking them off and leaving them at home. That’s what stood out to me about this one. The biggest advantage is how thin it is. I can leave it attached to my phone and still slip everything into my pocket comfortably, which means I actually carry it with me instead of only using it when I know I’ll need extra power. Charging performance has been exactly what I’d expect, and the build quality feels solid and premium. I also like that it uses semi-solid-state battery technology. I’ve been reading more about that recently, and it was one of the reasons I decided to give this one a try. It gives me a little more confidence carrying a battery pack with me every day. Overall, it’s the first magnetic power bank I’ve owned that feels practical enough to stay on my phone when I need it, instead of becoming something I take off after a few minutes. ... show more
