Helmet-mounted fan "My Fan Plus Helmet Mounting Kit" It allows for airflow and heat dissipation inside the helmet, as well as airflow to the neck area. This product is designed for heat prevention for field workers, warehouse workers, delivery personnel, factory workers, security guards, etc. It is considered effective for heatstroke prevention to "cool the back of the neck." Developed as a helmet-mounted fan, this product enhances heat prevention measures for each worker at job sites under the blazing sun. Despite being a compact fan, it provides strong airflow, effectively reducing temperature rise at the back of the neck and inside the helmet during outdoor activities. Additionally, it can be securely fixed to the helmet with dedicated bands and clips, ensuring safety. ■ The Ministry of Health, Labour and Welfare recommends wearing "fan-equipped helmets" ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ In March of this year, the Ministry of Health, Labour and Welfare announced the "STOP! Heatstroke Cool Work Campaign," urging businesses to thoroughly implement heatstroke prevention measures in the workplace. As part of this campaign, they began recommending the use of "fan-equipped helmets," which has garnered significant attention.

The battery charger UC6.0 is now on sale. - Compatible with automotive, ISS vehicles, HV auxiliary equipment, and motorcycle LiFePO4 batteries - Charges vehicle batteries while they are still installed in the vehicle - Selectable triple output charging for different purposes: 1A, 4A, and 6A - Power supply function - Battery recovery (sulfation removal) function It features a 6A output for fast charging, a 4A output for battery-friendly regular charging, and a 1A output for periodic maintenance charging. It accommodates a wide range of battery sizes, from large batteries in regular cars to those in light vehicles and small capacity batteries (such as for motorcycles and special small vehicles). For vehicles that are used infrequently, it can serve as a maintenance charger that is always connected, allowing for safe trickle charging, which alleviates concerns about restarting after long periods of non-use. Additionally, it prevents frequent battery replacements due to over-discharge, making it economical!

【Battery Tester Catalog 2023 Renewal】 DHC-DS brand products are officially adopted by major battery manufacturers and automotive manufacturers both domestically and internationally, who highly value their accuracy, functionality, and design. Thanks to the world-renowned patented technology SLDR, batteries can be diagnosed quickly and accurately without putting any strain on them. The DHC-DS battery tester conducts diagnostics using the patented technology SLDR. SLDR (Single Load Dynamic Resistance) is a technology that measures the internal state of the battery by briefly applying a high-voltage current, simulating the starting voltage when the car engine is turned on. Measurements using SLDR can accurately assess the internal state of the battery without being misled by surface charge, residual charge, or contact impedance, allowing for more precise measurement of battery capacity and diagnostic results. Since there is no thermal influence, it enables quick, accurate, and repeatable testing without burdening the battery. - US Patent: US6,369,577 B1 - European Patent: 1314990 - Taiwan Patent: 165571 - China Patent: 200810006984.9
