TESSAN AERO 5000 - A Titanium MagSafe Power Bank as Thin as 3 Credit Cards

Power banks always come down to "how thin and light can it get," so the TESSAN AERO 5000 caught my eye immediately — it's 6.9mm thick, about the same as three stacked credit cards. What really got me was the combination: an iPhone-grade titanium unibody paired with a semi-solid-state battery cell.

Placed next to an iPhone to compare side profiles — it really is about as thin as three cards

Attached to an iPhone. The topographic-pattern finish is simple but still has a distinct visual flair

Compact enough to fit neatly in one hand — feels like you could carry it around like a card wallet

🔍 Why I'm Interested

The thickness genuinely rivals three cards

The biggest reason I stop carrying a power bank is that it's too thick and heavy — but at 6.9mm, this could slide into a wallet or card case without adding any real bulk. Even attached to an iPhone, the case-plus-battery combo shouldn't feel much thicker than usual.

Titanium unibody + semi-solid-state battery combo

It's not just built thin for the sake of it — the iPhone-grade titanium construction adds durability, and the semi-solid-state battery cell itself is reportedly safer than a conventional lithium-polymer cell. The impression is "thin, but not flimsy."

Real-world charging speed is clearly disclosed

There's a concrete figure — 25% charge in 42 minutes on an iPhone 16 Pro — which gives you a solid sense of how much charge you'd actually get from a quick top-up in a pinch. Supporting both 15W magnetic and 20W wired charging is a practical bonus too.

🤔 Things That Give Me Pause

5,000mAh is roughly one full charge

To hit that ultra-slim profile, capacity had to be sacrificed — this is basically enough for one full iPhone charge and not much more. That could fall short if you need multiple top-ups throughout a full day out.

Still in the pre-order stage

This is a pre-order price ($69) ahead of official launch, so the actual retail price and domestic availability remain to be seen. Shipping is reportedly slated for October, so a hands-on review is still a ways off.

Semi-solid-state battery is still an early technology in real-world use

Semi-solid-state batteries are getting attention for their safety profile, but since they haven't been in consumer products for very long, long-term durability is something we'll only really know with time.

🎯 Final Verdict

A power bank always comes down to a trade-off between "how thin and light" versus "how safe and sturdy," and the TESSAN AERO 5000's attempt to nail both at once is impressive. Packing a titanium unibody and a semi-solid-state battery into a 6.9mm body isn't a combination you see often.

The 5,000mAh capacity itself isn't huge, but for the "carry it like a wallet, pull it out when you need a quick top-up" use case, the form factor fits perfectly. It's still at the pre-order stage, so a hands-on verification is needed, but if you're after a slim MagSafe power bank, this one is worth keeping an eye on after launch.
