The total surface area of the solar panels is 231 cm² (2x 115 cm²) for a total weight (including casing) of 848 g. We carried out our output tests in optimal conditions (i.e. bright sunlight). Here are the results obtained from the two different ports:
20V (max.) power port
Running a device directly from the solar panel
Powering a product with no intermediary battery depends whether or not the given device will accept power from the solar panel directly. Ideally, the device you want to run shouldn't require more than 5 Volts and 600 mAh if you're using the USB port, or 11 to 19 Volts and 450 mA for the other power connection. As with the powermonkey, you'll also need very bright sunlight, otherwise power could cut out any time a cloud comes along. In other words, you'll need to keep a battery close at hand to keep the device powered up until bright sunlight returns.
- Up to 3 W at 5 V via USB output
- Up to 7 W at 17 V via other output
- 3.7 times more powerful than the powermonkey at 5 V
- Supplied with case
- Three times heavier than the powermonkey-eXplorer
- No battery supplied
The solargorilla charges a 5 V battery three times faster than the smaller model, the powermonkey-eXplorer. It is, however, also three times heavier. Is it worth investing in a heavier and more expensive charger to ensure better performances? Yes if your luggage is in the car, but think twice if you're on foot.
