This is a solar charger which can charge most portable electronics, including smartphones from Apple, Samsung etc, battery packs from PortaPow and other manufacturers. It features a powerful 7 Watt solar panel, more powerful than typical mains chargers. This is enough to charge as fast as a wall charger in optimal sunlight, and provide a useful charge in slightly cloudy conditions. The panel can charge your devices directly without needing to first charge a built in battery as with rival designs. This is more efficient, lighter, and smaller. The panel includes a pocket on the back to keep your device safely stored during charging and folds in half when not in use.
It is flexible, and covered in a tough water resistant fabric to withstand the light rain and the occasional splash and knock.
A voltage controller is built in, so you can charge your devices directly from the panel without a first having to charge up a battery pack as with rival designs. You can also use a battery pack you already have or purchase one of ours if you want to store power and later charge your gadgets.
We have just released a model with more than double the power output, this will charge your gadgets faster in less than ideal conditions making it useful all year round. Click here to view.
Which devices does it charge?
Since the the panel features a USB socket, it can charge the thousands of devices which charge over USB. It also has a cable which is compatible with our interchangeable tips to extend the range of devices even further, allowing you to power all current phones and smartphones as well as thousands of PDAs, digital cameras, GPS navigators and mp3/video players. Micro USB, Mini USB, Nokia, and an Apple connector are provided as standard to cover the majority of devices, others are available here. Apple iPhones/iPads do not support trickle charging so will not work well in cloudy weather. We would recommend using the solar panel to charge a battery pack and later using the pack to charge Apple products if the weather is not sunny.
How powerful is the solar panel?
The charger uses a large 7 Watt (5V x 1400mA) monocrystalline panel. This is the most energy dense form of panel, and gives more power for the same area compared to poly/multi crystalline panels. This means it can charge your devices 5-10x faster than rival portable solar chargers. Note, solar panels will only achieve the stated power in ideal circumstances, and will only output a fraction of the power if it is cloudy, the panel is inside a window, or if the panel is not directly facing the Sun. This panel is powerful enough that even in these conditions it will still slowly charge your devices.
We recommend you buy the panel together with our USB Power Monitor so you can see exactly how much power the panel is outputting and angle it exactly to increase the amount of sunlight captured.
The power of a panel is measured in Watts, if you're comparing a rival product that does not state the wattage, this is calculated by Voltage x Current, eg 5V x 1400mA = 7000 milliWatts, which is 7 Watts. Remember to look at the power of the panel, not the battery pack supplied with the panel which is usually more powerful.

Been chasing the sunny spots around,so far intermittent success,thinking about getting the 15 W version to allow for the UK's spring weather, can see the potential though for if really sunny weather.
Excellent bit of kit

Bought this as a backup for a camping trip. Charged my smartphone in about two hours of decent, direct sunshine. Even when cloudy and raining the panel still works to trickle charge whatever it's connected to. Only problem we have had is with my wife's iphone5, it seems to charge slower than everything else and we have had to disconnect and reconnect because the iphone doesn't recognise the charger as a power source. I think the fault is with the iphone as we have used the panel successfully on about eight or ten different appliances

Really well constructed in a tough nylon case. Folds in half to protect the solar panels whilst carrying. A useful pocket on the back which carries the Premium USB battery pack that I also purchased. In good sunlight the panel charges my smart phone very quickly and even continued to charge when the sun dropped behind the trees. A single wire direct from the solar panel is all that is needed to charge either the battery pack or mobile device. Plenty of loops on the case to hang on a rucksack and easily stands on the ground whilst in camp. Overall, really impressed.
really necessary :-)

I bought with confidence with PortaPow because I previously bought their premium USB battery pack (6600mAh) and it was of excellent quality. Likewise, this solar panel has the following pros:
1. Folds in half, saving space when unused.
2. The panels are protected from all sides, so it is easier to carry and store than a "bare" type of panels sold on eBay.
3. Comes with a voltage regulator, so as not to risk damaging expensive gadgets with variable voltage.
What are the cons? Hmmm, I have another similar solar panel (also 5V/1A with USB output) which has the compartment for inserting 4 rechargeable AA batteries which are used as a "backup" and I find this feature very convenient. I.e. the AA batteries are in the circuit to compensate for the current drop when the sun is behind the clouds and also they are recharged "in the background" from the excess current when available. It would be nice if PortaPow considered this improvement.
