    Usage Note: The amount of charging current depends on the strength of the sunlight on the panel and may at times be very low. When presented with a low charging current, some devices may display an error message indicating that "Charging is not supported with this accessory". For best results, use these solar panels to charge a Power Bank, then use the Power Bank to charge your mobile devices.

    How can a device with maximum voltage and current ratings of 5 Volts and 2100 mA be rated at a maximum output power of 15 Watts when Power = Voltage x Current and max power should only be 10.5 Watts, if the voltage and current specs are correct?
    Daniel G on May 12, 2017
    BEST ANSWER: Thank you for your inquiry. The maximum Output Voltage and current rating via the USB-A Female port is 5V/2.1A which does equal 10.5 Watts of power. This 15W Solar Charger provides the ability to charge 2 devices at one time, and across these 2 ports, the Panel offers a peak power of 15W.
    How durable is this?
    An S on Jan 22, 2017
    BEST ANSWER: It feels quite rugged. The exterior material is stiffer than typical canvas. I would not hesitate to attach to a backpack or leave on a rock or ledge. That said, these are solar panels and none are indestructible. You don't have to baby it, but don't toss it around too much, either. Should last for years.
    Can you use it on a wireless charger, my charger function isn't working and this would help?
    Bob C on May 12, 2017
    BEST ANSWER: Assuming you are referring to a wireless charging pad: If your wireless charger utilizes a transformer at the other end of the cable (a little box that plugs into the wall), AND that cable can be disconnected from the transformer, then you should be able to plug the large USB end of the cable into this solar charger to power your wireless charging pad (and charge your electronic device).

    If the transformer, cable and pad are all one unit then you will not be able to use this to power your wireless charging pad.
    Can you daisy chain two or more of these together?
    Taylor M on Apr 5, 2017
    BEST ANSWER: There is no way to do that, at least as it is designed and outfitted. There is a input jack for higher voltages along with a corded plug and the adapters to match almost anything at the other end of the provided cable. And there is a standard USB jack for 5v.
    Do these have a charge controller/regulator built in?
    Karen H on Mar 19, 2017
    BEST ANSWER: Thank you for your question. This solar charger will have a charge controller built in. It would be located in one of the flaps and will allow you to connect via USB. I hope this helps.

    Excellent product!!!
    I've never owned any solar-charging product before this, and I didn't want to set my expectations too high as far as how fast it would charge. I decided to test it this morning on my Samsung Galaxy 6 smartphone, which was down to 4% power. I turned the phone off, plugged it into the solar charger, which I placed in direct sunlight on my deck railing (late morning, end of September in New Jersey). I came back an hour and twenty minutes later, thinking if it went up 15-20% I'd be happy, but it was up to 84%!! Couldn't believe it! Got to 100% charge in an hour and forty minutes from when I plugged it in. This product FAR exceeds my expectations. Great job, Monoprice!

    PROS: VERY fast charging, and seems like it's well-made with good materials. I'm extremely happy with this product.

    CONS: Have found none yet.

    Works great - good price
    This item works as advertised. Placed it in the sun - used a DROK meter to determine power being provided (over 1.5 amps at 5V) and it was almost the same as a wall charger when I plugged in a phone or tablet. Would have no problem charging a phone, tablet (I tried a 10" samsung), or battery power banks. Much cheaper than the other ones available on Amazon. Make sure to keep the items you are charging out of the sun but keep all three panels in full sun - covering up one of the panels with my hand significantly dropped the amps.

    PROS: strong power output
    cheaper price

    CONS: cant think of any

    Solar panel charger
    First time to use it today. Charging up storage battery. Battery was down to one bar. It's been about 2 1/2 hours charging in some sun but mostly overcast and its up to 3 bars out of 4. Shouldn't be long now until it's fully charged. Faster than I expected especially with it being mostly overcast today. Very happy with its performance.

    PROS: Works well even on a semi overcast day.

    CONS: None

    Good solar charger
    Works like a charm, even on cloudy days. Charges large backup batteries fast I use for my iPad and phone when outdoors. I will order two more this week.

    PROS: Easy to lay out, connect the cables to the two on-board USB and just "let it alone"

    CONS: The pocket for the cable is way too small and not rain water tight... that needs improvement.

    Works as Advertised
    I am very pleased with this product. The first time I tried it was a little early in the morning so it didn't work too well. About an hour later the sun was high enough in the sky that it worked great. Obviously this item works best when the sun is highest in the sky, and charges my cell phone as fast (if not faster) than a wall charger. It even works well on the dash of my car while I am driving.

    PROS: Well made and works fastest at high noon.

    CONS: A little expensive but the price of everything solar is going down these days

    Bought 2 more after trying the first one
    3 solar panels work great under sunny day, and still able to charge under cloudy day

    PROS: great for outdoor, camping and off-roading. Now my kids won't use up all my power to charge their ipads

    CONS: None

    Good Solar Charger
    I used this charger on a cross country trip. It works best in direct sunlight for charging small electronics. I paired it with a back up battery from monoprice that I could charge during the day while doing my activities. It did take all day to charge but did the job. On a hike in Big Horn National Park, the sun was out and I was able to strap it to my backpack and charge my phone while hiking. It didn't charge it much during the hike due to being in and out of the sun, but the charge percentage did go up rather than down during the 2 hour hike.

    PROS: Small and foldable with loops for affixing it to a pack or other object.

    CONS: loops can come loose and I had to re-sew one that came undone.

    Portable yet Powerful
    This thing is fantastic! I purchased it to charge a power bank while we were away on a kayaking trip. Although it wasn't in full sunlight, it still was enough in partial shade to charge both our phones. It will definitely be a key part of our camping gear this season.

    PROS: Folds up small
    Solid construction
    Pouch for cables
    Loops that you can use to clip to backpacks

    Great charger - Free energy!
    This is a great charger. It's great to be able to charge those devices for free! I have used it to charge a Monoprice 8000mAh battery both inside in a window and outside. (I use this battery to charge either my iPhone or my iPad.)
    When using inside in a cloudy day, a high pitch wining can be heard, but the device slowly charges.
    When using outside in the same conditions, there is no noise and the charging proceeds well.
    I am quite satisfied with this product at this point and would recommend it to others.

    PROS: Free energy
    Easy to use, just unfold in a bright day, connect, and charge
    Easy to carry
    Provides power without having to connect to the grid

    CONS: Works better outside than inside on cloudy days
    Nothing indicates that the device is water proof, so need to be careful when leaving something outside to charge

    Works great - nice self contained case with small pocket for cables.
