KV-20SM solar charging unit is a perfect solution for those who like to spend time outdoors not parting with their favorite gadgets, but have a limited budget. These units will easily charge the majority of mobile phones, smartphones, MP3-players, iPod, iPhone, Blackberry, AA-, AAA-, CR123R batteries (which can then be used to power GPS, sonars, flashlights, mini-cameras) even in cloudy weather. These charging units have enough output to be able to charge accumulators for SLR cameras, video cameras, tablets and netbooks. Using these units it becomes possible to charge laptops.

Included into the set charge controller is designed to convert and control solar module output voltage (up to three nominal values – 5 V, 5.7 V (via USB) and 12 V (when charging via car cigarette lighter)). It also provides the ability of visual control of irradiance level and connection of an external energy storage unit (12 V AGM or Li-pol battery) with capacity up to 18Ah. For each accumulator type we have developed individual charge characteristics that guarantee their durability and high-performance service life.

Maximum load current under condition of battery supply is 2.5 A (when charging via car cigarette lighter) and 1.5 A (when charging via USB). We have also protected the User against emergency conditions: after an accidental short circuit or controller output circuits overload current flow will be stopped automatically and subsystems will remain undamaged.

In the folded state KV-20SM is almost similar to a case for 15” laptop, that in combination with its light weight gives us confidence that users will not have any problems with transportation of our devices.

In case in a walking tour your electronic companion doesn’t require more energy than a mobile phone, we advise you to pay attention to solar charging units of KV-3.5 series.  But if you need significant amount of energy under bad light conditions it is better to switch to the description of devices belonging to the higher output class (KV-40М and higher). And for the most extreme conditions but the same output we offer a frame-based solar charging unit KV-25TM .

* equivalent to power generated within a full sunny summer day under standard conditions (t=25 °C, irradiance 1000 W/m², light incidence angle 90°).
