Test of Brunton 2 solar panel - English verson
Kindly translated by www.butlerweb.dk
Eventyrsport (Adventuresport) in Hillerød asked me in relation to the upcoming tours during the summer, if I would test their solar panel / solar charger e.g. for my smart phone and camera.
I have adit with me for the last 4 months using it frequently and with great satisfaction! A great function is that it is not just a solar panel. You can charge it prior to your adventures, having a fully chharged battery pack, that doesn't need recharging from the sun at first. Like having a spare container of gas in your back pocket. Charging it fully from a wall plug takes about 2 hrs.
Charging it only based on the sun differs: It is dependant on the amount of sun it can receive. So it depends on the season, drifting clouds/shade etc. I tried having it on my garden table and a full charging took about a day (app. 10 hrs). It can even charge if you put it inside the apsis/outer tent, which to me was a surprise!
The charged power can be transferrred to your smart phone/camera/PC etc. via a mini USB plug with 1000mA and 5V.
BUNTON claims that charging your cell phone with the fully charged Brunton panel is as quick as charging the same phone in a wall plug. I tried 3 times and timed it. It's true within a margin of less than 5 minutes. Impressive!
The solar panel is water repellent, not waterproof, which means you cannot charge it on the deck of your kayak. Unless you have it in a transperant waterproof bag. But I only used it on land.
When the dew sets in at night, or the constant moist that is inevitable when on a kayaking tour doesn't affect the panel at all. And the summer of 2011 in Denmark has been the most rainy within living meory!

If one needs charging of a smartphone or other electrical equipment when on an adventure, or just a small weekend trip, then I will surely recommend the Brunton 2 Solar panel. . It doesn't need as much sun light as anticipated. Works even in a tent, and fully charged it is coparable with the charging time of a wall plug. And teh fact that it is water repellent fits like hand in glove for us: the kayakers!
