SECURITY REDEFINED!

SEMI-SOLID-STATE

The new generation of powerbanks impresses with state-of-the-art SEMI-SOLID-STATE technology that stands for particularly high safety, long service life and reliable performance. Unlike conventional Li polymer cells, SEMI-SOLID-STATE technology uses a partially solid electrolyte that is significantly less flammable and offers a more stable, safer structure. This new technology also enables higher energy density, excellent thermal management and high resistance to shocks and temperature fluctuations. It delivers significantly more charge cycles and a consistently stable output over its entire lifetime.

More bang for your brand, not for your battery:
SEMI-SOLID-STATE!

Even in the event of severe external impact that would damage the battery pack, the SEMI-SOLID electrolyte would significantly reduce the risk of fire and explosion, as well as swelling and overheating. The innovative SEMI-SOLID-STATE technology therefore delivers a substantially higher level of safety than conventional lithium-ion batteries. At the same time, it offers greater performance with the same battery pack size — for powerful, reliable energy in everyday use.

Customization options:

The new power banks equipped with SEMI-SOLID-STATE technology offer generous, highly visible branding areas that are ideal for effective brand presentation. Depending on the model, laser engraving, pad printing, and brilliant UV digital printing are available, making it possible to create both subtle, elegant brand appearances and eye-catching, full-surface designs. This turns the power banks into high-quality brand ambassadors for everyday use.

Good to know

Conventional powerbanks (Li polymer)

  • Liquid electrolyte, more easily flammable
  • Higher risk of overheating and thermal instability
  • Greater likelihood of deformation (“swelling”)
  • Sensitive to ambient temperatures
  • Relatively low number of charge cycles
  • Noticeable performance loss over time
  • More susceptible to damage (e.g. pressure, puncturing)

Powerbanks with SEMI-SOLID-STATE technology

  • SEMI-SOLID electrolyte, significantly lower risk of fire
  • Better thermal management, reduced risk of overheating
  • Dimensionally stable, hardly any swelling
  • Significantly higher number of charge cycles, usable for longer
  • More stable performance over the entire lifetime
  • Exceptionally robust, remains functional even under “stress tests”

Häufig gestellte Fragen

Why is a SEMI-SOLID-STATE power bank safer than a conventional power bank?
In a SEMI-SOLID-STATE battery, the electrolyte is bound in a semi-solid form. Even under severe mechanical stress that would damage the battery pack, the risks of fire, explosion, swelling, and overheating can be significantly reduced. In addition, multi-level protection circuits are used, for example against overcharging, short circuits, and overcurrent.
Does a SEMI-SOLID-STATE power bank deliver the same performance as a regular power bank?
Yes. SEMI-SOLID-STATE power banks provide a stable and powerful energy supply — their performance is even higher than that of conventional lithium-ion power banks. Depending on the model, various capacities and outputs are available, such as USB-A, USB-C, and fast-charging functions, so that smartphones, tablets, and other devices can be charged quickly and reliably.
Does a SEMI-SOLID-STATE power bank last longer than conventional models?
SEMI-SOLID-STATE batteries are designed for high cycle stability. This means they can generally be charged and discharged more often before their capacity noticeably declines. Thanks to the more stable cell chemistry, this can have a positive effect on the service life of the power bank — provided it is used and stored properly.
Is it possible to order power banks in a custom color?
Yes, custom-made versions in your individual brand color are generally possible. In most cases, we can realize such projects starting from a minimum order quantity of around 3,000 units. Depending on your requirements, such as special colors, additional details, or custom packaging, extra costs may apply. Simply tell us what you have in mind — we will check feasibility, color specifications such as Pantone, delivery times, and prepare a tailored quote for you.
