Hands International (Yokohama, Kanagawa) will begin selling the 28W foldable solar booster from Xtorm, a mobile battery brand from the Netherlands, on Friday, May 29, 2026. Xtorm is a Dutch mobile charging solutions brand that develops high-performance, environmentally friendly products, gathering support in 63 countries worldwide, primarily in Europe.

By using it in combination with a mobile battery, you can generate and store electricity yourself. This provides a secure power solution that allows you to generate power with solar energy, store it in a battery, and charge devices repeatedly even during power outages.

Product Details

High-Efficiency Solar Charging

With up to 24% conversion efficiency due to monocrystalline cells, stable power generation is possible even in environments with weak sunlight. It supports small devices such as smartphones, cameras, drones, and tablets. Monocrystalline cells have a uniform crystal structure that allows electrons to flow smoothly, enabling efficient, waste-free power generation. This solar panel is also reliable with long life, remaining stable even in low light or high temperatures.

Waterproof and Lightweight Design

It features a foldable design for excellent storage and is lightweight at 910g. With IPX4 life-waterproof specifications, it can handle light rain and splashes, allowing for peace of mind during disasters or outdoor activities. It also comes with overcharge, short circuit, and overheat protection functions. Since it does not contain a battery, there is little risk of heat generation or ignition, making it safe to use.

Simultaneous Charging & Output Display

Equipped with two ports, USB-C (15W) and USB-A (15W), it can charge two devices simultaneously, such as a smartphone and earphones. You can check the power generation amount and optimal angle in real-time on the LCD screen.

A New Disaster Preparedness Strategy: Equipping an 'Environment Where You Can Charge'

After disasters like earthquakes or typhoons, power restoration is estimated to take about 72 hours, but if power outages are prolonged, mobile batteries will eventually run out. Therefore, what becomes important is not just 'storing' power, but being prepared to 'generate' it. As it can be stored compactly and spread out only when needed, it is perfect for disaster bags or in-car storage. It is useful for outdoor activities and camping, serving not just for 'in case' scenarios, but for daily use as well.
