A new ultra-thin power bank measuring just 6mm thickness is now available at €60, making it thinner than any current smartphone on the market. The device comes in Glacier Silver, Graphite Black, with a Radiant Orange option at €65. For travelers and professionals who refuse to carry extra bulk, this is a significant achievement in portable charging design.

Power banks have gotten slimmer over years as battery density improved and charging circuits became more efficient. But 6mm is remarkable. Most phones are 8-10mm thick. A power bank thinner than your phone is genuinely innovative. The tradeoff is obviously capacity—this won’t charge your phone fully multiple times. It’s for emergency top-ups.

Practical Limitations

At 6mm, this power bank probably holds 3,000-5,000 mAh. Modern phones have 4,000-5,000 mAh batteries. So this bank gives you one full charge, not more. That’s still useful. Carry it in a shirt pocket and you’re covered for a full day without finding an outlet. The tradeoff between thinness and capacity is a real choice users have to make.

The €60 price is reasonable for a designer object. You’re paying for form factor, not capacity. A regular power bank with double the capacity costs less. But a 6mm bank fits places other banks can’t. It slips into a wallet. It tucks into a jacket pocket. For some people, the form factor justifies the price.

Material and Design

A 6mm power bank requires premium materials to maintain structural rigidity. Standard plastic would flex and crack. The device probably uses aluminum frames and precision engineering. That adds to manufacturing cost. The color options (Glacier Silver, Graphite Black, Radiant Orange) suggest the design is intentional and aesthetic, not purely functional.

USB-C support is standard on devices this new. Fast charging probably maxes out at 18-20W given the size. That’s slower than modern phone chargers, but perfectly adequate for portable banks. The real selling point is not speed but form factor.

Market and Competitors

Anker and other battery companies already make compact power banks. But none are 6mm thin. This design is genuinely novel. Competitors will copy it eventually. Once they do, prices will drop and the market will normalize. Until then, this is a premium product for people who refuse compromise on thinness.

The 6mm power bank proves that industrial design still matters in tech. It’s not the fastest charger, not the highest capacity, not the cheapest option. But it’s the thinnest, and for some people, that’s everything.
