Quick answers

Questions, answered quickly.

The practical stuff: daily capacity, flying, device fit, safety, and charging.

Nine answers, from real charge and phone fit to warmth, controls, and travel.

Is 5,000mAh enough for daily carry?

Yes. Air 5K is the daily top-up version: enough backup power for the phone-first day while staying thin enough to carry without thinking about it.

Can I fly with SolidSafe Air 5K?

Yes. At 19.25Wh, SolidSafe Air 5K is below the 100Wh carry-on battery limit. Carry power banks in your carry-on, not checked luggage, and always follow your airline rules.

How is Air 5K different from the regular SolidSafe 5K?

Air 5K is the ultra-thin, pocket-first version. It trades the LCD display and built-in lanyard cable for a 6.8mm titanium form factor with LED dot indicators and a single USB-C port.

What does semi-solid-state mean here?

It means the cell uses significantly less liquid electrolyte than a conventional lithium-ion design. That helps reduce battery risk while keeping the power bank compact enough for daily use.

What devices can it charge?

It charges MagSafe-compatible iPhones, Qi2-compatible phones, USB-C phones, earbuds, cameras, and other small USB-C devices. Wireless charging reaches up to 15W where supported, and USB-C output reaches up to 20W.

Can it charge two devices at once?

Yes. SolidSafe Air 5K can charge one device wirelessly and one device through USB-C at the same time. If one device is already charging and you connect a second, press the power button once to activate the additional output.

Can I recharge Air 5K from my laptop's USB-C port?

Recharge it from a USB wall charger or a USB-A port with the included cable; it refills at up to 15W. It won't reliably recharge from a laptop's USB-C port. That port and the Air's USB-C are both two-way, so they can't agree on which one charges the other, and the lights stay lit without cycling. This isn't a defect. Use a wall charger instead.

I hear a faint buzzing or high-pitched sound when it's charging. Is that normal?

Yes. That's the charging coil at work. The components that move power quickly can give off a faint hum, wired or wireless. It's easiest to hear when the battery is low (the coil works harder), when the room is quiet, or because the Air is thin enough that there's less material between the coil and your ears. It fades as charging finishes and doesn't affect charging speed, battery health, or safety.

Why does the Air 5K get warm while charging?

That warmth is the titanium shell doing its job. Charging always creates some heat, and wireless charging a bit more than a cable. Rather than trapping that heat inside, the metal body carries it to the surface and lets it disperse, which is exactly why you feel it in your hand. It's most noticeable when charging wirelessly or topping up a large phone. Warm is normal. But if it ever gets too hot to hold comfortably, stop using it, unplug it, and let it cool, then contact our support team so we can help, it's covered by the 2-year warranty.

What comes in the box?

SolidSafe Air 5K and a USB-C charging cable.

Customer video review of SolidSafe™ Air 5K Solid-State Qi2 Power Bank w/Titanium Enclosure

I have 6 of the 5,000 milliamp hour slim batteries which are way Slimmer than one of the other competitors if I can figure out how to add a second picture to this review I would do it they're really nice Chargers I bought the gold tone one just so it wouldn't blend into furniture when I lay it down. The connection is very strong and it's nice to have a strong mag back style battery so tiny and this one works better than the other brands 5K one with way less heat. I plan to give the other brand away. Also Samsung's qy2 charging system doesn't seem to be quite as good as Apple my wife has the Apple but the other brands 5K and even 10K batteries don't normally charge my phone all the way back to the top these ones do. I also have the 10K ones, and the charger that I bought for them is really nice customer service says that they are come out with a charger for the slim 5K wins I anxiously wait that because the charging case is really nice.

I was on the fence about buying this, because I really wanted the semi-solid-state and the titanium casing and sleek design, but I also wanted more juice. I waffled back and forth a while and finally pulled the trigger on this, because the convenience of having something so slim really outweighed any concerns I had about capacity. And so far this little thing is amazing.

Its slow to charge my iPhone and it gets quite warm

Jeffrey H. 2/5 Verified

SolidSafe™ Air 5K Solid-State Qi2 Power Bank w/Titanium Enclosure

Store owner replied: Hi Jeffrey, thanks for flagging this. Wireless charging is slower and runs warmer than USB-C, and the titanium housing can make that warmth more noticeable. For the fastest, most efficient charge, please try the included USB-C cable. If the warmth seems excessive, email support@heybmx.com with your iPhone model, case, charger, and order number so we can check your setup and unit. If it becomes too hot to hold, swells, smells unusual, or shows damage, please stop using it.

Love the design and love the thought. The magnet which connects to the case doesn't align it directly with the charging so it takes a lot of fidgeting and micro movements to try and get it set perfectly to charge. The charging is also a little slower than I expected but worked well with my sister-in-law's iPhone. Not sure if it's just that this was not designed for a pixel. For reference, pixel 9 pro with a d brand case.

I really like the SolidSafe™ Air 5K Solid-State Qi2 Power Bank. It's small, lightweight, and easy to use. I especially like the fact that it's a solid state power bank and not a completely lithium power bank. I trust I can bring it with me hassle-free the next time I travel by air.
