Voltaic SystemsArc 10 Watt USB Solar Charger | Powers Phones, Tablets, & More | Charges Your Device as Fast as at Home

I bought this after a friend brought it to the beach with us one afternoon. My portable speakers were dead (i forgot to charge them before hand), but I plugged them into the Voltaic solar panel and the JamBox came to life. This panel is great because you can charge to a battery pack for later but you do not need to. My speakers ran off the power from the sun all afternoon. Not only was the power enough to produce sound but it also charged my speakers. I returned home with nearly a full charge after playing music for roughly 5 or 6 hours. That was a very sunny day but i was charging my phone last weekend through my apartment window on a cloudy day. The panel is light weight and takes up almost no room. I wont be leaving home with out this next time I'm going to the beach, park, hike, camp etc.

it's too bad, it's lightweight, looks durable. the corners doesn't have grommets as described in the photos. but the panel does not work. it will connect and disconnect almost immediately from the device charging despite being in full sun. I have to disconnect the cord completely to attempt starting the connection again.

I travel annually, often out of the country to places where electricity is not as reliable. I bought the Arc Solar Charger to charge my Nook tablet, which I use to keep a journal when traveling.But first, I wanted to make sure that it did the job. The instructions say that you CANNOT charge the Arc Solar Charger through a window. So I tested it by connecting it to my tablet and setting it on my front porch in direct sun. The tablet did not register any incoming charge (charger was not powering the tablet). I read my tablet owner's manual and realized that the output of the Arc Solar Charger is too low for the Nook tablet.I considered sending it back, but then had another thought: could I use the Arc Solar Charger to charge a battery pack? I researched various models and found one that had an input strength equal to that of the Arc Solar Charger's output, the Anker PowerCore. I went with the 10000 model. Back to the porch, with the Arc Solar Charger and the battery pack. Success! The PowerCore immediately began drawing power from the Arc Solar Charger! I left both units out for the afternoon, with the PowerCore charged to about 25% (one of the four indicator lights solid) by sundown.I was able to take both the Arc Solar Charger and the Anker PowerCore on my next trip. When I ran low, I tried charging, but on a day that was a little overcast. The Arc Solar Charger was only able to charge the PowerCore to less than 25% from morning to evening.In conclusion, the Arc Solar Charger works, but I cannot give it the highest marks. It may work better for cell phones than it did for either my Nook tablet or my Anker PowerCore. Perhaps in a locale or on a day with brilliant sun, it would charge faster than it did for me. On the plus side, it makes a handy protective cover for my Nook while traveling!

A little pricey compared to some of the other top notch brands, however, it appears to be pretty solid. It uses SunPower panels which are simply the best out there. Works really well so far. I am not totally sure as of yet but I do think the quality of your usb cable makes a difference. I use top notch Anker cables and it would indicate it is charging on my iPhone and using another cable in same situation, it would not show a charge. I will update this review if I find any info to indicate otherwise.

This works alright. It’s not the strongest and it isn’t the weakest...as long as you’re fully aware of the possible limitations compared to what you want to charge, it is fairly sturdy and it does charge phones and such. It feels like it is made of some pretty good solar cells and covered in a sort of epoxy to keep them durable. The USB (USB-A) port on the back is helpful as you can plug it into a power bank or directly into a cell phone. The advantage of charging a power bank is that power will be available even when its cloudy instead of just sunny (if you use this to directly charge a phone or whatever). This is one of the more portable solar cells that I’ve had as it folds like a sort of heavy paper folder from back in school. This feels like it is water resistant and it should be able to take a fair beating without issue. Overall, I can’t complain; I just wish the value was a bit better.Pros:Seems to be made wellEasy to usePuts out a pretty good charge for its sizePortableSeemingly water resistantDoes a good job charging my phone and power bankCons:Doesn’t have USB-C port on backIsn’t cheapTakes a bit to charge a phone in fullOverall, if you love solar or need one that feels more durable and don’t mind it costing a bit of a premium, this could be ideal. I’d rate it 3.5 stars if I could

Just finished a 7-day hike in the Pacific Northwest with this. It was able to to keep my devices charged (with the help of a portable battery pack) through the entire journey. It works better than my other Goal Zero panel and weighs less as well.

Took me 9 hrs just to get 20% of battery in my phone. I attempted to use it multiple times and then I gave it away because it was not useful at all and it was expensive for no reason.

It's a nice design, compact, but not very useful since it often stops charging. This requires unplugging and replugging the USB cable to restart the charging, which doesn't work very well if it's on the back of one's backpack.
