Arun 40W

Portable Solar Charger with SUNPOWER + ETFE Technology

Tested and Certified



  • VOLTAGE REGULATOR | Detect your device automatically, and offer a best charging current intelligently, achieve fast charging and prolong your device lifespan. Equipped with Voltage Regulator to ensure stability. The only minus of free sunlight is not stable, solar panel powered by unstable sunlight leads to untable current and voltage, which will shorten device’s life or even damage it. Litionite solar panel with Voltage Regulator keeps our device getting stable current and prolong its life.
  • SUNPOWER CELL | Litionite use top brand Sunpower high efficiency solar panel from USA, with top quality and efficiency, offers 22%-25% efficiency. Compared to normal monocrystalline silicon panel with about 17% energy transfer rate, “Sunpower” High Efficiency solar panel from USA is over 25% energy transfer rate reaches WORLD TOP level, in this way, your charging process is faster and more convenient. So it also benefits from the size of the panel, more power in less solar surface.
  • ULTRA LIGHT, COMPACT DESIGN | Unfold to 874 x 299mm while folded only 292 x 299mm, you can folded into a handbag with a handle and carry it easily.
  • DUAL OUTPUT | 1x 20V/2A DC output port with large power compatible to battery charges of your Litionite Power Generator or Power Bank, laptops, and most of your 20V devices. 1x 5V/2A USB output port compatible your cellphone including iphone and android phones, and competible to most of your 5V devices like cameras, PSP, MP4 etc. + Litionite Power Banks.
  • TOUGH IN THE SUN – HIGH QUALITY, TESTED MATERIALS | The waterproof, UV, and scratch-resistant coating is built to last and go wherever you go. The 40 watts folding panel uses ETFE Laminate coating instead of PET to last outside at least 3x longer than competitors’ products. | Four rivet attachment system to easily attach to backpacks, bicycles, and other travel gear.
  • PERFORMANCE WINTER | Even when it’s cloudy outside, your solar panels will still produce electricity. As long as there is light, your system will convert it into clean energy. If you choose our SunPower solar panels over other conventional panels, you’ll have a system that is proven to hold efficiency much better in low-light conditions. On cloudy days, light is diffused and scattered in all directions. We use high-quality anti-reflective glass that traps incoming light from all angles, capturing more sun than conventional panels.
  • COMPATIBILITY | Designed and recommended for the following our Power Bank Series: Dragon, Tanker, Wolf, Hurakan, Raiden, Vulcan.

ETFE is a fluoropolymer, or a polymer (a macromolecule made up of a chain of the same molecules) that contains fluorine atoms. The molecules that composes the polymer are chemically very stable and therefore can withstand high levels of thermal stress and chemical aggression, much more than PET can do. Another fundamental feature of ETFE, which makes it an excellent polymer for this field of application, is its total UV permeability: numerous tests carried out also on outdated samples (to prove the durability of this feature) show a permeability of 95 % (Compared to an average of 80% of PET). Not only is ETFE a durable and "UV-friendly" material, but is also "intelligent": thanks to the chemical properties of its molecules, ETFE is a self-cleaning material that maintains its transparency for its whole life cycle, which in optimal conditions can reach even 20 years (Hightex data). Another sign of its "intelligence" lies in the environmental sustainability of this polymer: in fact it is 100% recyclable.

SunPower Cell

High-efficiency SunPower has reached a production average cell conversion efficiency of 25%, the highest in the industry.
Sunpower Cells use back-contact conductivity, eliminating unsightly metal gridlines, and enabling them to absorb more sunlight.
It is designed and tested to stand up to some of the harshest conditions: temperature swings, battering winds, humidity, hail and more. In fact, it will have a useful life of more than 40 years.
Conventional solar cells lose power over time because of corrosion and breakage. But the unique design of SunPower solar cells eliminates 85% of the reasons conventional cells fail.
