Elecom Co., Ltd. (Headquarters: Chuo-ku, Osaka City; President and CEO: Koichi Ishimi) will launch the 'Safe Charging-Only Cable (USB Type-C™)' in late July 2026, designed to protect users from risks associated with charging via USB ports in public locations such as cafes, airports, and hotels.

Ahead of the launch, a survey on awareness and behavior regarding public USB charging revealed that approximately 60% of users charge their devices while feeling concerned about security. Additionally, 93.5% responded that 'countermeasures are necessary' against 'juice jacking'—a cyberattack that exploits public USB ports. The results highlight the urgent need to prevent data theft and malware infections.

What is Juice Jacking?

Juice jacking is a cyberattack where hackers use public USB ports to secretly steal data from or install malware (viruses) onto connected devices such as smartphones and tablets, disguised as charging. As this can occur in everyday locations like cafes, airports, and hotels, preventive measures during charging are essential.

Survey Summary

The survey revealed that about 60% of those who have used public USB ports charge while feeling insecure, while approximately 40% were unaware of 'juice jacking' as a cyberattack method.

The most common response to this anxiety was 'avoiding charging when possible' (46.2%), while only about 30% of all users reported using proper countermeasure tools.

While public USB ports are commonly found in cafes, airports, and hotels, the results highlight that many users feel uneasy due to insufficient protection.

Four Key Insights from the Survey

[Point 01] About 60% Charge While Feeling Anxious

When 353 respondents who had used public USB charging ports were asked about their sense of anxiety, 60.1%—comprising 17.3% who felt 'very anxious' and 42.8% who felt 'somewhat anxious'—reported charging while feeling insecure about safety.

In contrast, only 6.2% answered that they 'felt no anxiety at all,' clearly indicating that most users are aware of potential risks.

Notably, 73.8% of respondents in their 30s and 68.1% in their 20s reported feeling anxious, while only 32.6% of those in their 50s felt anxious—the lowest among all age groups—revealing a significant generational gap in risk awareness.

[Point 02] 'Wanting to Charge but Holding Back'—Most Common Response to Anxiety is 'Giving Up Charging'

When 212 respondents who felt anxious were asked about their countermeasures, 46.2% said they 'avoid charging as much as possible.' This indicates that the most common response to anxiety is not using protective tools, but simply giving up on charging altogether.

While 47.2% of those feeling anxious reported using data blockers or charging-only cables, this figure applies only to the anxious group. Among all users, only about 30% actually use such protective tools. Given that 38.5% were unaware of the term 'juice jacking,' the real issue may not be unwillingness to act, but a lack of awareness about available solutions.

[Point 03] Only About 60% Are Aware of the Cyberattack Risk

When asked whether they knew about 'juice jacking' or 'choice jacking' cyberattacks, 61.4% answered 'well aware' or 'somewhat aware'—nearly matching the 60.1% who felt anxious when charging. This suggests that awareness of risks correlates with heightened anxiety and preventive intentions.

When awareness of the term 'juice jacking' was analyzed by age group, 73.0% of respondents in their 50s answered 'not aware (heard it for the first time).' This is significantly higher than the 19.3% among 20-year-olds and 21.6% among 30-year-olds. Coupled with the fact that only 32.6% of 50-year-olds felt anxious—the lowest rate—this raises concerns that older users may be unknowingly exposed to risks.

[Point 04] After Risk Explanation, 93.5% Responded 'Countermeasures Are Necessary'

After reading an explanation of juice jacking, 93.5% of respondents—49.9% saying 'strongly necessary' and 43.6% saying 'somewhat necessary'—felt that preventive measures during charging were needed.

Moreover, while 50.8% of those who 'well knew' about juice jacking answered 'very anxious,' none in the 'unaware' group gave the same response. This shows that awareness of the risk is a key driver in raising preventive awareness.

Introducing a USB Type-C Cable for Safe Charging Anytime, Anywhere

The survey revealed that many users feel anxious when charging at public USB ports in cafes, airports, and hotels, and that a large number recognize the need for countermeasures. In response, Elecom has developed the 'Safe Charging-Only Cable (USB Type-C™),' featuring a 'Data Blocker' that physically blocks unintended data communication to prevent unauthorized data theft and protect against charging-related risks.

A Convenient and Flexible USB Cable

Supports charging via USB Power Delivery, compatible with smartphones, tablets, and notebook computers.

Printed markings on the connector indicate product specifications.

Uses flame-retardant materials to enhance safety.

Features gold-plated pins that resist corrosion and minimize signal degradation.

An eco-friendly product compliant with the EU's RoHS Directive (10 substances), restricting specific hazardous materials in electrical and electronic equipment.

Choose Power Output (Wattage) and Cable Features Based on Usage

Two power output options: 60W (20V/3A) and 240W (48V/5A), both enabling fast charging.

In addition to the standard model, users can choose between the 'High-Durability Model,' featuring three enhancements—high-density wiring structure for improved bend resistance, nylon mesh material to prevent surface scratches, and a long bush structure to reduce stress on plug areas—and the 'Smooth Model,' which uses soft, smooth silicone material that resists tangling and is easy to handle.
