Torras MiniMag Pro promises cooler charging with semi‑solid‑state battery

At a glance:

• Torras introduces the MiniMag Pro, a magnetic power bank that stays around 98°F (37°C) during sustained fast charging.
• The charger uses a semi‑solid‑state battery architecture, a technology more common in EVs than in consumer accessories.
• Two capacities are offered: 5000 mAh at 8.5 mm thickness and 10000 mAh at 14 mm thickness, both with PPS support.

What torras is targeting

Fast‑charging has become a double‑edged sword for modern smartphones. Users love the speed, but the heat generated can make a phone uncomfortable to hold, slow down charging through thermal throttling, and, over time, degrade lithium‑ion cells. Torras argues that the market has been fixated on raw capacity—mAh numbers, thinner casings, and higher wattage—while ignoring the thermal side‑effects that matter to everyday users.

The company’s new MiniMag Pro is positioned as a response to this gap. By emphasizing “cooler charging” as a premium feature, Torras hopes to shift consumer expectations from “more power” to “smarter power,” especially for people who keep their phones attached to a magnetic charger while navigating, video‑calling, or gaming on the go.

How the miniMag pro works

At the heart of the MiniMag Pro is a semi‑solid‑state battery architecture. Traditional lithium‑ion cells rely on liquid electrolytes that can heat up quickly under high current. Torras replaces part of that liquid with a gel‑like electrolyte, which offers better thermal stability and reduces the internal resistance that typically creates heat.

In plain English, the semi‑solid‑state design means the charger can sustain high‑speed charging without the temperature spikes that plague conventional power banks. Torras claims the surface temperature stays near 98°F (37°C) even during prolonged, heavy‑load sessions—a figure that is roughly the same as a comfortable room temperature and well below the 120°F+ levels seen in many competing magnetic chargers.

Why semi‑solid‑state matters

Semi‑solid‑state batteries have been a buzzword in the electric‑vehicle (EV) sector for years, praised for safety, energy density, and longevity. Torras is among the first accessory makers to bring that technology to a consumer‑grade power bank. The benefit is twofold: lower heat generation improves user comfort, and the more stable chemistry reduces the risk of swelling or thermal runaway, a concern that becomes more pronounced as devices get thinner and charging speeds increase.

The move also hints at a broader trend where high‑performance battery chemistries migrate from niche industrial applications into everyday gadgets. If the MiniMag Pro’s architecture proves reliable at scale, we could see a new generation of accessories—headphones, wearables, even laptops—adopting semi‑solid‑state cells to balance power and safety.

Design and specs

Torras has managed to keep the MiniMag Pro remarkably thin despite the added thermal‑management layers. The 5000 mAh version measures just 8.5 mm in thickness, while the larger 10000 mAh model is only 14 mm thick. Both variants support Programmable Power Supply (PPS), allowing compatible phones to negotiate optimal voltage and current for faster yet controlled charging.

The magnetic alignment system is engineered for secure attachment during movement, so users can type, film, or navigate with one hand while the charger stays firmly in place. The slim profile and magnetic snap‑on design align with the “invisible tech” philosophy that modern consumers favor—accessories that blend into daily routines rather than standing out as bulky add‑ons.

Safety testing and consumer impact

Torras says the MiniMag Pro underwent puncture testing and extreme pressure testing to validate its structural integrity under stress. While most buyers won’t watch the test footage, the results translate into tangible benefits: a charger that feels cooler in a backpack, maintains consistent output while traveling, and is less likely to contribute to long‑term battery wear on the attached phone.

As smartphones continue to pack more AI‑driven features, higher‑resolution video capture, and always‑on connectivity, thermal management is becoming a decisive factor in purchase decisions. Torras is betting that safety and temperature control will soon be as marketable as raw capacity, nudging the premium accessory segment toward smarter, not just bigger, power solutions.

What this could mean for the market

If the MiniMag Pro gains traction, it could set a new benchmark for portable chargers. Competitors may be forced to explore alternative chemistries or add active cooling solutions to keep up. The shift could also accelerate the adoption of semi‑solid‑state batteries across a wider range of consumer electronics, narrowing the gap between EV‑grade energy storage and everyday gadgets.

Ultimately, the MiniMag Pro exemplifies a broader industry pivot: moving away from spec‑sheet races toward real‑world performance metrics like temperature stability, longevity, and user comfort. Whether this translates into higher sales for Torras remains to be seen, but the conversation around “cooler charging” is now firmly on the table.
