Solar energy has been around for a while, if we take into account the development period of solar panels. However, due to the fact that large panel arrays are needed in order to produce a reasonable amount of energy, until recently no compact devices were released for the SOHO segment.
The expression "Until recently" says it all because in the latest two years solar panels have become more and more effective and, as a result, compact solar chargers started to replace standard ones. And that's exactly the case of the Solar Port 4.4 with BattJack Battery Charger, presented by the people over at Brunton since the first half of 2006, which is in fact one of the most efficient devices of its type. When it comes to solar panel efficiency, the result is measured in the total wattage obtained from a given surface. And if you take this reasoning and apply it to the Solar Port, the result won't be at all disappointing.
The vendor doesn't specify the exact wattage output, but we believe it to be pretty high, given the surface of the active solar panel. That statement is based on the fact that with the help of this solar panel it is possible to charge 4 AA batteries in a matter of hours. Obviously, this process is achieved with the help of a charging unit that is included in the Brunton Solar Port 4.4 with BattJack Battery Charger package.
When charging NiMh/NiCd units, one has to take into account two things. The time it takes to charge the batteries depends directly on the power of the sun, and for this reason you will be able to use the device for 6-14 hours depending on your location. Moreover, different rechargeable batteries have different capacities, so it's normal for a 2500mAh unit to charge slower than a 1200mAh one.
