The BMX SolidSafe 10K has many advantages over traditional power banks. However, there are also a couple of issues.

I've fallen in love with BMX power banks powered by solid-state batteries. These banks do away with older lithium-ion batteries that include the flammable liquid electrolyte and instead use a solid-state battery that's a lot safer (I know, I've put a screwdriver through a fully-charged one and nothing happened).  The BMX SolidSafe 10K is another in the company's series that doesn't disappoint, and it's the bigger — and in my opinion, better — brother of the SolidSafe 5K.  The SolidSafe 10K is a 10,000mAh power bank built to reduce the risk of fire and explosions by eliminating the flammable electrolyte in the battery.  So, why do I like solid-state batteries so much?

The main reason is that they're safer. A lot safer. Like, you can rupture a fully charged battery pack, and all you get is a whiff of smoke. No fires. No plumes of smoke. No dramas.  But solid-state batteries have a couple of other benefits. The first is lifespan. While a standard lithium-ion battery is good for around 500 recharge cycles, a solid-state battery is good for at least 1,000 before the capacity drops to the point the battery is considered end-of-life.  It is a substantial power bank, but the magnets do a good job of keeping it in place.  Another thing I like about solid-state batteries is that they work much better in colder temperatures than regular lithium-ion batteries.

On top of that, they can be recharged at a lower temperature, which is an advantage when you're off-grid and there's no heat. If you had traditional power banks, you'd have to put them inside your clothes to warm them up for charging.   The BMX SolidSafe 10K is a 10,000mAh/38Wh portable power bank that measures 4.0 x 2.7 x 0.6 inches and weighs 7.4 ounces. Those measurements are definitely on the hefty side for a magnetic power bank (it's a couple of ounces heavier than a standard power bank).

However, some of that heft is due to the bank's beautifully anodized aluminum and polymer shell. The device features a Qi2 wireless charging pad that can deliver up to 15W of power to a compatible handset. The magnets are strong and can hold the power bank in place, no matter how rough and tumble your life gets, even if your phone is in a thick case like mine. The SolidSafe 10K also has two USB-C ports (the 5K model had one), and it supports pass-through charging.

The ports support a maximum of 30W output and 27W input. The dual-port setup is a boost because I can travel with a small single-port charging block. Then, at the end of the day, I can plug the charger into the wall and use it to charge the power bank while simultaneously wirelessly charging my iPhone and another device via the second USB-C port.  There's a button on the power bank to turn it on, and there's a color display on the front that shows power levels and charging/discharging power.

The display is crisp and clear, and shows all the basic information. The SolidSafe 10K also comes with a lanyard that's actually a small USB-C-to-USB-C cable. This feature is a nice touch because it means there's a good chance that I'll have a cable when I need it.  The retaining clip that holds the cable in place is pretty ingenious. The clip has resisted all my fidgeting — and it hasn't broken or given way, sending the power bank hurling through the air.  The power banks come in four finishes — black, blue, orange, and silver — and you can pick one up for $79.99 (which is $20 off the full price).

For that money, the BMX SolidSafe 10K is a fantastic power bank. Yes, this bank is pricier than many other MagSafe power banks. However, the device has two USB-C outputs (a rare feature).  It's also a sturdy power bank that really delivers on what it promises, and the solid-state battery offers a safer experience, a longer lifespan, and better cold-weather performance (if that's important to you).
