When you go to camp, a hike of several days, where any other reason that we deprive several days of electricity, we can ask the question of how to charge its small electronic devices, whether phone, Tablet, GPS, cameras or other devices. For that, we can carry spare batteries, but they also have a limit and if it takes several, it becomes fast heavy in the bag, especially if you have to walk and space is limited. There is another alternative, a source of energy that available in 99% of cases, there is solar energy. For this reason I decided to test the solar charger 10W with USB of ECEEN output.
Content of the box and technical features:
- 1 x solar charger ECEEN 10 W
- 4 x carabiners
- 1 x cable micro USB 40 cm
- 1 x instruction manual
- Power: 10W
- USB output: 5V / 1500 my (max)
- Solar energy conversion rate: 22%
- Folded size: 28 x 15 x 1.3 cm
- Weight: 800g
- Color: black
The test
The solar charger is in the form of a black fabric pouch that closes with a zipper. Once unfolded, there are 2 solar panels that provide power 10W. Before continuing, to be clear, it is not a battery, there is no way to accumulate energy, it's only a charger! However you can use it to charge a backup battery to have electricity in dark weather or at night also when traveling. 
There are hooks unfolded all around the object for the fixed to his backpack for hiking, for example, in all 14 areas of hangs there and 4 carabiners are provided in order to hang it on a bag backpack, in the position you want. Inside, it has a USB port hidden in a little pouch that protects with a zipper. This pouch is 12.7 x 20.3 cm. It is large enough to slide a small USB battery or a phone for example. 
In optimal conditions, the charger can deliver 1.5 has 5V output to charge devices. The charger adapts to your devices, IE the USB ports will deliver the maximum intensity that can support your device, no need to pay attention to this detail so. The load is possible from the moment where it picks up a good light, that is to say a clear and clear time is sufficient, not necessarily need to be in full sun. 
Load speed is however naturally proportional to the light power received by the solar panels. It's pretty handy, because suddenly we can use it everywhere outdoors, even if we are not in full sun, on the picnic table, or the beach back car for example. In case of rain or wet areas, signs solar themselves are water resistant but not the rest of the electrical part the USB connector or devices that will put you in charge. So be careful and avoided in the left alone in the middle of nature is in charge if you are not on time.
Conclusion
This solar charger is ideal for holiday in nature, hiking trips or camping, the adventurers so an external battery is not sufficient for your devices. It is both small and light, and can therefore be easily slide into her bag. It inspires confidence and seems to be of good quality with a good finish.
