Anker 8 watts Solar Charger with PowerIQ Technology
Tap into the sun’s radiance and power up with freedom.
Brilliant power supply.
When you’re out enjoying the great outdoors, enjoy yet another perk: free limitless power. Well-placed eyeholes enable easy attachment to your pack, tent or even trees.
Roughly the size of an iPad Air and weighing less than a pound, the 8W Solar Charger adds minimal bulk to your backpack.
Industry grade PET panels are bound together with heavy-duty polyester canvas, equipping this solar array with ultimate weather-resistant durability.
For Optimal Use:
- Minimize exposure to water to protect electrical components.
- Use your device’s original cable or a third-party certified one (such as MFI).
- Compatible with Apple and Android smartphones, tablets (including the Nexus 7) and other USB-charged devices except for the iPod nano, iPod Classic, HP TouchPad, Dell Venue 11 Pro and Asus tablets.
PowerIQ: Detects your device. Delivers the fastest charge.
Not all charging ports are created equal. Standard ports only charge some devices at full speed and others often really slowly. But with PowerIQ technology, each port intelligently identifies your device to deliver its fastest possible charge speed. So you save hours of time (weather permitting).

Tap into the sun's radiance and power up your gadgets with freedom.
Brilliant power supply.
When you're out enjoying the great outdoors, enjoy yet another perk: free limitless power. Simply spread out the solar panels or attach to your pack to start repowering your gadgets. 8 watts provides enough power to charge one device at a time.
PowerIQ: Compatibility maximized.
Not all charging ports are created equal. Standard ports only communicate effectively with particular devices, like Apple OR Android, often limiting their recharge rate. But with PowerIQ technology, each port intelligently identifies your device to speak its unique charging language. So plug in any brand or model and enjoy compatibility that doesn't limit your charging speed (although the weather still might).
Folding down into an easily–stowable paper–sized package and weighing in at less than a pound, the solar charger adds minimal bulk to your backpack. Well–placed eyeholes enable easy attachment to your pack, tent or even trees.
The panels are faced with industrial–grade PET plastic and bound together using heavy–duty polyester canvas, equipping this solar array with ultimate weather–resistant durability. Premium materials and circuitry ensure lifetime reliability.
For optimal use.
• Minimize exposure to water to protect electrical components.
• Compatible with ALL USB–charged devices (except the Asus Transformer and iPod Classic).
• To ensure complete safety and best performance, we strongly recommend using your device's original cable or a third–party certified one (such as MFI).

I recommend that you review the accompanying video first. I purchased the Anker PowerPort 21 watt and Aukey 20 watt portable solar chargers within the last week. Neither was provided in consideration for this review.
The test was accomplished on a sunny nearly cloud free afternoon at about 1:30 p.m. Both three panel fold outs were arranged in nearly identical positions on a small table in my back yard. An inexpensive Drok LED USB tester was employed to measure output from both products.
Both products utilize SunPower solar panels, reputed to support conversion efficiency up to 23.5%. Both also include controllers to allow for the fastest possible charging speed up to 2.4 amps to each of two USB ports. Both employ canvas fabric and Pet polymer faced panels with a water resistant design; water resistance was not tested on either unit.
The 1 amp USB port was used on both products. Switching the meter to the other port did not produce additional power. The USB charging cable provided with the Anker product was used on both; a cable was not provided with the Aukey unit.
As shown in the video, the Aukey 20 watt product produced 5.15 volts at 0.51 amps for a total of 2.6265 watts. Power, measured in watts, is equal to voltage multiplied by amperage. While the output from one USB port should be substantially less than that from both combined, the substantially lower realized output is instructive. Both units consistently produced sufficient power to cause my 5 inch Android phone to reflect charging.
The Anker 21 watt product produced 5.11 volts at 0.52 amps for a total of 2.6572 watts. Despite being rated at 21 versus 20 watts, both chargers supplied about the same power to the Smart phone. I strongly suspect that both the Anker and Aukey solar chargers would have charged at a much higher rate had something more than a 5" Smart phone been used. In this regard, the same Smart phone only charged at 4.93 volts at 0.47 amps using the same Drok meter with a regulated power supply running at 13.8 volts into a vehicle USB charging port. That both the solar chargers charged the Smart phone at a greater rate than the regulated power supply would tend to validate the claim of both manufacturers that their solar chargers would charge at the fastest rate safely possible for a given device.
PHYSICAL PRODUCT COMPARISON & CONCLUSION
Both products include metal clips and or fabric loops to allow easy attachment to backpacks or other objects. The Anker uses four metal eye holes whereas the Aukey has four fabric loops and a single metal eye hole. Both have comparably sized storage compartments and use Velcro to secure the foldout panels. Anker includes a red LED between the USB ports to signify charging. The Aukey additionally includes an attached rigid panel sized board for positioning of the panels.
The power output is sufficiently close to nullify that as a serious consideration. Construction and components are also essentially the same. Both appear to be of Chinese design and manufacture.
I believe both were worth more than what I paid for them, although the Aukey cost me $5 less. I did a fair amount of research prior to buying these products and believe both are deserving of excellent ratings. My technical video reviews routinely require at least a couple of hours to produce and I would appreciate a helpful rating if you found it so.
Since some of you might be interested in seeing how the Anker Solar Charger did under a greater load, I placed the panels on the same table about 1:15 p.m., again with a nearly cloudless sky; the temperature was again about 50 degrees. This time, I added a 20 amp NewNow S25 USB storage device to the 5" Android phone. The storage unit is rated at 5 volts at 1.5 Amps input.
With the panels laying flat on the table, the Drok meter registered 4.64 volts at 1.28 amps (5.9392 watts). By lifting the panels more toward the sun, the voltage rose to 4.98 volts and 2.19 amps (10.9062 watts). Only one of the USB ports on the charger was used. The Aukey charger was not tested, but since it employs the same brand, quantity and size panels, I have no reason to believe the results under a greater load would have been substantially different.
POSTSCRIPT - STATING THE OBVIOUS
While there is no simple answer to realized solar panel efficiency, suffice to say that you are much more likely to achieve good results in Arizona than in New England. That is, panels located closer to the equator on a sunny day have far greater potential for producing solar electricity than the same ones closer to the poles. This is a function of radiance, the single most important determinant in panel efficiency. Obviously, radiance is much better on a cloud free day than an overcast one. Just as obvious, panels are also much more efficient if pointed at the sun,
For a much better understanding of solar panels, I suggest you consult UGov.Net, American Home Disaster Preparedness. Understandably, I'm not paid to do this and the site is clearly a work in progress.
Either turn off your phone before charging or use it to charge a powerbank then use that to charge your phone.
With that aside, I've never seen a 1amp coming out of this 8W solar panel.
I suggest using a 3 panel solar charger, much more reliable and doesn't get phone into charge/discharge cycles as often.
