Specifications Item No. : Infinity SL-01 Main material: Upper case is ABS + CIGS solar soft board + EVA soft bottom case Capacity: 26L Weight: 2.2kg Size: 53 * 30 * 18cm Wattage: 10W / 12W Volt: 5.0V Current: 1.6A / 2.4A Features: Waterproof, colorful enclosure, USB external port Description The solar panel uses a thin-film solar soft board. The soft board is light and easy to carry and has bending flexibility, which is better than the general polycrystalline silicon solar hard board sold in the market.
Although monocrystalline silicon and polycrystalline silicon solar panels have slightly higher charging efficiency than the thin film process, they have the disadvantages of heavy weight and fragility, and are not suitable for outdoor travelers.
The upper case of the photovoltaic backpack is an ABS ultra-tough and ultra-thin shell, which has sufficient rigidity to protect the surface of the solar panel and the contents of the backpack. The inner lining is mainly high-density twill nylon fabric.
The lower case of the photovoltaic backpack is a soft EVA shell, which can cushion the weight of the human body.
The photovoltaic backpack lies flat facing the full daylight (no cloud cover or other shade), which can increase the charge of the mobile phone( under 2000ma battery capacity ）by 30% in one hour. If it is midday or summer sunshine, the charging efficiency will be higher.
