Fast charging has a heat problem. You’ve felt it before: your phone gets hot while driving, your MagSafe battery pack turns into a hand warmer during a Zoom call, or charging slows due to thermal throttling. As smartphones become more powerful, portable chargers struggle to keep up.
That’s where the MiniMag Pro from TORRAS comes in, offering a magnetic power bank with a unique focus: cooler charging.
Portable chargers have hit a wall. For years, the competition centered around capacity—more mAh won. But modern smartphones demand more power than ever, leading to increased heat generation during fast charging. This is not just uncomfortable; it’s detrimental to lithium battery health.
Most accessory brands accept this as a trade-off, but TORRAS does not.
The MiniMag Pro utilizes a semi-solid-state battery architecture to maintain a surface temperature around 98°F (37°C) during prolonged charging sessions, even under heavy loads. This is significant because magnetic wireless charging often leads to excessive heat buildup.
Wait, semi-solid-state? In a power bank? Traditional lithium-ion batteries use liquid electrolytes, but semi-solid-state batteries replace part of this with a more stable gel-like material. This results in:
- Less heat: Improved thermal stability and reduced internal risks.
- Better stability: Enhanced overall performance under stress.
- Denser packaging: Thinner designs without sacrificing capacity.
The 5000mAh version of the MiniMag Pro is just 8.5mm thick, while the larger 10000mAh model offers faster charging speeds and PPS support despite its 14mm thickness.
This isn’t merely about faster charging; it’s about smarter charging. The real innovation here signals a shift in mobile power technology.
