BigBlue Solar Charging
This portable solar charger is user-friendly, and compatible with all USB rechargeable devices. This inexpensive charger operates on sun energy so produces 100% green power and has amazing 21.5% to 23.5% solar efficiency.
Unfold the charger panels and place the BigBlue 5V 28W unit wherever you can access direct sunlight and the portable solar charger panels get to work. It even charges your device in partly cloudy conditions. You can relax, admiring the panorama as you charge your cell phone, tablet, GoPro, GPS or camera.
Built-in Ammeter and Pocket with Zip
The BigBlue 5V 28W folding panel package includes 4 clip hooks, which allows you to hook your solar panel everywhere convenient to get solar access (trees, backpacks, vehicle, etc.) It is bulky when it is unfolded, and with all its features it is slightly heavier than less powerful units in the portable range, albeit there is no inside solar battery for storage included in that weight.
The panels are rated as waterproof but this is rating is for splashed water and intermittent rain showers. An internal chip ensures that when the panel loses contact with sunlight for a period of time (walking through dense forest, rain cloud shadow, intermittent shadow from placing it on a moving backpack), it will stop charging until he comes back into contact with the sun's rays, without damaging your connected device.
The built-in ammeter and the pocket with a zip will keep your devices safe and clean while they are being charged. Remember that Apple devices have a chip that closes the phone down and stops the phone charging whenever its inner temperature get too hot.
An overheating situation may occur, even when it's inside the BigBlue's zip cover if you have the solar panels together with the charging phone out in full sun. You might save the phone from overheating by using a longer USB cable and keeping the phone in shade, either a ventilated area or insulated inside a backpack. You need to place the solar charger's panels in full sunlight, without shade and obstacles that may cause an intermittent shadow.
Most customers gave the device a good rating. The rating was 4.2 out of 5 stars.
