Solar charging unit of KV-3.5M series is a miniature source of electricity created to be a reliable and convenient companion for backpackers, hunters and fishermen.

Due to its small size when folded it can be easily placed into a backpack pocket and its weight is 5 times less than the weight of AA batteries with the capacity equivalent to the one that solar charging unit can generate within one full sunny summer day. This solar charging unit allows direct charge of the majority of mobile phones, smartphones, MP3-players, iPods, iPhone3 even when the weather is cloudy. AA, AAA and CR123R batteries (which can then be applied to power GPS, sonars, flashights, cameras) are charged via additional adapters. In case of using an external storage device capabilities of these devices expand and they are able to work with SLR cameras and video cameras. Charging time of compatible devices is comparable with charging time from the power grid (under standard conditions).

iPhone4 and Blackberry are charged only under direct sunlight. Solar charging units are made in the form of a portable folding case which contains solar cells and electronic stabilizer.

To avoid mechanical damage solar cells’ front side is securely covered with fiberglass substrate and polycarbonate based composite film. The device is assembled and embedded in a case made of wear-proof and moisture-resistant fabrics.

The distinctive feature of KV-3.5BM devices is availability of suitable eyelets, designed for secure fastening of opened charging unit to a backpack, tent, etc. In KV-3.5CM model the stabilizer is located in a separate unit and is connected by means of long cable. Due to this the device thickness was reduced and it is possible to use it even when it rains (after placing the stabilizer in a dry place).

In case it is necessary to charge high capacity batteries or batteries with nominal voltage of more than 5V, charging units of the present class are ineffective here. Thus, we recommend you to pay attention to charging units of higher power class (KV-10 and others).

* equivalent to power generated within a full sunny summer day under standard conditions (t = 20 °C, irradiance 1000 W/m², light incidence angle 90°).
