FlexSolar 2-Pack 6W Portable Solar Charger Panel, Shockproof Mobile Power Charger，Solar USB 5V Regulated Output for Smart Phone,Power Bank and GPS Units.

Solar panels work as expected, some direct UV rays and you got yourself a very green/eco charger. These will NOT instantly charge your phone ultra fast, it is a trickle charge but it works great in my case. Only downside is the product photos are misleading. It appears that the two panels can work in tandem but in reality they each have a separate USB output. Unless an additional device/dongle/splitter is purchased these are two separate solar panels.

Took this solar panel hiking in Texas backcountry, I had an iPhone for pictures and emergencies. It recharged my phone quickly and perfectly in sunny and cloudy days, exceeds my expectations. There are two packs, flexible to share with your friend or use both. Easy to hook with your backpack. Almost half price with most of its competitors but good quality. Fashionable and lightweight design. I'd recommend this charger without hesitation, especially as a perfect family emergency recharge device when out of electricity.

Reasonable price and lightweight for portable applications, but actual peak power output is much lower than advertised. Closer to 3.5 watts, with peak amperage at 0.7amps. See attached photo of voltage and amperage test.

These are pretty good really durable don't give much power output at all though.

I bought these as a power source for my security cameras. They dont put out enough power as stated to charge the batteries. Tried with my cell phone and said slow power charge. These are nice quality but the overall performance is still week.

Awesome design

Very well constructed and perfect for my custom esp8266 moisture sensors for my garden. This keeps the 18650 battery fully charge with no problems. Will be purchasing many more as my outdoor sensors expand.

I always love the solar energy idea! The one is a great addition for outdoor lovers. Will try it when we go to camping. Also recommended it to my friends.
