ALLPOWERS 16W Solar Panel Charger with iSolar Technology for Cell Phone, iphone, ipad, Samsung and Other Smartphones and Tablets

So far it's good. In the weak New England December sun it charged my LG smart phone 13% in 19 minutes. Despite being at 11:30 am the sun was low in the sky. Charged the phone from 65% to 95% fast via hanging the panel on the mini van's hood. Added some charge to my Goal Zero Guide plus AA battery pack however the panel's electronics did make a slight buzzing sound during that process but not when charging my phone. Maybe it's an issue of the higher draw. For example the Goal 10 plus does the same thing when charging an Azus 10.1 inch tablet but it's silent when charging my cell phone. In any case I don't think the buzzing harms anything plus it's not all that loud.Was unable to charge both the LG and Goal Zero guide 10 plus AA charger at the same time in the drying 3 pm December sun but frankly was surprised it could add charge to either singularly given the weak sun which it did. The produce feels and looks well made. Both USB ports and red charging indicator LED works. The included USB cord is long enough for it's intended purpose. It came with two aluminum clips for attachment to a pack or in my case the windshield wiper.Also the price seems good for this item. So why no 5 stars? I simply don't have enough long term experience with this product to say it's worthy of 5 stars. If you're reading this review months or years from now and I have not added comments on any failure then assume this is a 5 star product. If something goes wrong I will let the community know. As of right now I consider this a good buy for those wishing to charge small electronics, rechargable batteries etc etc etc.edit. I am pushing up my rating by one star to 5 stars. Testing shows this to be a good product. Unless something changes it will remain 5 stars. Also company has great customer service so I purchased another panel and will do a review of that as well. In good sun this can add charge to both a Guide 10 plus and my cell phone at the same time. Once had it charging 6 AA at the same time (4xAA charger and 2XAA charger) but that needs strong sun. Still it preforms great.

I think when reviewing products its always important to factor in price. Yes it does not put out as much power as a Ravpower or Anker solar panel, so it won't charge your devices as quickly. But they are rated at a higher wattage and costs 3 times as much. This product works well. I think I paid about $20, and for the money its a great buy. In good sunlight it will easily output 1A or higher. In overcast conditions i think anywhere from 200-500ma. You might think that is not enough and it will take all day to charge a phone. You would be right. But if you use it to charge a usb battery pack then you can leave it charging all day. I bought this for camping trips. The idea is to connect 1 or 2 battery packs and charge them all day, and use the battery packs at night to charge the phones or other devices. Even just pulling 200mA on an overcast day could give you 1600-2000mA, thats enough to get most cellphones a 70-100% charge. On a good day you could potentially get 8000-10000mA. More than enough to charge a couple phones a day. If you are also wanting it for camping than you probably will take a couple portable battery packs that are maybe 4000-6000ma that are charged up beforehand. Without recharging them they would last a couple days by themselves if you had a couple devices. Now top up those same packs with this solar panel everyday and you really should have plenty of juice for a couple cell phones and maybe an iPad and USB rechargeable speakers. I have had the panels for a few months and will update my review if anything changes, but so far I am impressed with the performance and the build quality. I think its important to remember that if you just want something to give you 1 or 2 charges while you happen to be caught without a charger for 24-48 hours then you are better of with a battery pack. These panels are for extended stays away from power outlets, where you can set these up to charge all day.

Just got mine in the mail today. It does charge my battery bank very well but learned it is no good for charging my iPhone. I kept getting "accessory may not be supported" every time a cloud flew over the panels. Now if the sky is clear then wow this little sucker will charge it up like no ones business. For the most part this thing is awesome, but please use this setup to charge up a battery power bank then use said power bank to charge up your devices. Power banks are not as finicky and don't care if the charge is crappy or not. I may buy the higher panels next time though.Update 1 june 2015This will charge your Iphone 6 + albeit slowly but i got 6 percent in slight overcast skies during my lunch break.Update 14 feb 2016This thing just outlived my power bank and is still going strong. I charge my iPhone 6plus directly to it and noticed something. My phone used cut connection to the panels when it did not get sufficient juice but now it reconnects when it has enough again. I guess apple pushed an update to compensate for spotty connections. Good thing now is I can leave it locked in my car and set the panels on my roof and let it do its magic and come back 1 hour later to a full battery. From 35% in airplane mode of course. Meaning a battery bank is not really necessary anymore but I still would like one anyway. I am going to order a new battery from Aukey to really push its charging potential. The input on that battery goes up to 2.1 amps I have a monitor and I will put it to the test to see how much real power the panels can pump out . Also if you angle the panels toward the sun instead of laying them flat increases input quite a bit. My phone got 1.6 amps while it was charging doing that which was really impressive. So this is me almost a year in still loving this all powers solar charger. :)

Estoy tratando de cambiar a energias renovables, y he probado varios productos solares y muchos han sido un verdadero fiasco. Pero este producto puede cargar un iPad un poco lento pero si carga, Obviamente depende de la cantidad de sol, yo vivo en un mega desierto sin contaminación ni lluvias asi que aqui funciona de maravillla.

I like it.

No he tenido la oportunidad de probarlo pero los materiales da la impresion de gran calidad, costo adecuado para lo que promete
