CONCLUSION

   To test the Outdoor Solar Powerbank 24000 by Sandberg we used every smartphone, tablet, portable speaker and audio player we have in the lab (also a couple of USB capacity measurement tools) and after over 40 days and dozens of recharges the maximum we managed to pull from it was just over 16500mAh (between 16000mAh and 17000mAh) a number which is actually very good for an 24000mAh advertised model. Measuring the effective/real capacity of this model was not all we did however since we also wanted to thoroughly test the solar panel and see just how long it would take for a full charge. Unfortunately, although we do have sunny days here even during the winter it's far from what we get during the summer so it took a total of 8 days under direct sunlight for a full charge. That being said if the sun is out this can be a very useful feature and should provide enough battery juice per day for a single charge of any current smartphone (that of course depends largely on the intensity of the sun where you're at).

   Just like with most products by Sandberg the Outdoor Solar Powerbank 24000 model is not available in the USA but can be currently found for 120.12Euros inside the EU (Amazon.de) a price tag which is quite heftier than expected. This of course is due to massive competition in that segment of the market which basically means that you can find similar products for less. Still Sandberg does make it up (at least partially) with their 5-year warranty and excellent support and that combined with all its features and massive battery capacity are enough for us to give it our Golden Award.
