Xtorm’s 6-Stage Safety Check

Especially regarding safety, Xtorm products are equipped with a 6-stage safety mechanism, providing peace of mind during use.

Temperature Control: All Xtorm chargers feature a temperature control chip to prevent overheating.
Overcharge Protection: Protects both the internal battery and connected devices from overcharging.
Safe Power Management: Only the highest quality battery cells are used, providing necessary rapid charging and meeting all safety standards.
Short-Circuit Protection: Automatically cuts off the circuit if overcurrent is detected, protecting both the Xtorm charger and the connected device from damage.
A-Class Battery Cells: Automatically selects the optimal charging speed for the connected device and efficiently distributes power.
High Efficiency: Delivers power to devices as efficiently as possible, minimizing energy loss during charging.

Xtorm’s Role in Disaster Preparedness

The probability of a Nankai Trough earthquake occurring within the next 30 years is estimated to be 70-80%, and with the risk of Mount Fuji erupting and an unstable global situation, more individuals are becoming conscious of “preparedness.” However, household storage batteries exceeding 100,000 yen are not easily accessible for casual purchase, while small smartphone batteries are insufficient for maintaining power and communication during several days of outage.

Xtorm proposes a power solution that can be used daily for camping or business trips, and then become a primary item in a disaster preparedness bag when needed. This approach aims to prevent batteries from simply being bought and left unused on a shelf.
