Many of us carry power banks out of necessity, but dread their bulk. Old models felt like bricks, destined for forgotten cupboard corners rather than accompanying us on adventures. But battery technology is evolving, and a new breed of power bank is emerging – one that prioritizes portability without sacrificing performance.
The key lies in advancements beyond traditional lithium-ion batteries. Engineers are now utilizing semi-solid-state electrolytes, reducing the amount of flammable liquid and creating designs that are smaller, safer, and more efficient. These innovations are shrinking power banks to unprecedented sizes, offering a welcome relief for those constantly on the move.
Better Mobile Xperience (BMX) recently unveiled a power bank aiming to redefine “portable”: the SolidSafe Air 5K. While maintaining a typical length and width for magnetic wireless power banks, its depth is remarkably thin – a mere 0.27 inches (6.8mm). To put that in perspective, it’s even slimmer than the iPhone Air itself.
But thinness isn’t the only advantage. Weight is equally crucial. The SolidSafe Air tips the scales at 4.1oz (116g), making it barely noticeable in a pocket or bag. While not the absolute lightest on the market, the difference of a fraction of an ounce is unlikely to be felt by most users.
The design itself is thoughtfully executed. The magnetic coil is subtly raised to accommodate the slim profile, and the power bank is available in a range of stylish titanium finishes. A standard four-LED indicator displays remaining power, offering clear visibility at a glance.
Beyond aesthetics, the SolidSafe Air boasts impressive performance. Utilizing Qi2 magnetic charging, it delivers up to 15W of wireless power. Testing revealed an 89% recharge rate for an iPhone, placing it among the top performers in its class. A USB-C port allows for 20W wired charging, and simultaneous wired and wireless charging can deliver a combined 22W.
The 5000mAh battery provides ample power for a full iPhone recharge. The semi-solid-state technology also promises increased safety and longevity, reducing the risk of overheating and extending the battery’s lifespan through more charge cycles.
While the SolidSafe Air charges at a relatively slow 15W, a full recharge takes approximately two hours – perfectly acceptable for overnight charging. It’s a small trade-off for a power bank that truly disappears in your pocket.
The BMX SolidSafe Air 5K isn’t just a power bank; it’s a testament to how far battery technology has come. It’s a sleek, lightweight, and powerful companion for anyone who values portability and peace of mind. For those seeking the slimmest possible solution, the SolidSafe Air sets a new standard.
