Solar Backpack 7W Solar Panel Charge for Cell Phones and 5V Device Power Supply

I use this backpack constantly. It looks good, it's lightweight, and has impressive features. I haven't used the solar panel/battery pack as much as the camelback but it seems to work well. The camelback feature is fantastic, the mouthpiece never leaks and the hose doesn't get in my way when I'm riding. From the beginning I noticed a very small leak at the joint where the water pack meets the hose and that is a little disappointing. It's not big enough to cause any problems though. Also ECEEN seems to care a lot about their product and their customer satisfaction, which is awesome. They personally emailed me after the backpack had been quickly shipped and let me know about the product's 12 month warranty and that I was welcome to contact them with questions or concerns. For an item with a price tag exceeding $100, it is comforting to know the company backs up their product, even after the transaction is complete. Only complaints would be that tiny leak, pretty weak mesh pocket on the back of the solar panel, and a pretty much useless pocket on the right waist strap. I was initially really excited to see this pocket because i thought i could use it without taking off the pack–this was not the case. For reducing weight, listening to music, charging on-the-go, and looking fresh I definitely do not regret this purchase at all. But, like with most products, there are a few things I would change :/

Shipped this as a wedding gift for a friend who uses it constantly. I've the smaller 1L version. Have to say that with a flexible solar panel and a 10,000mAH ruggedized LiIon power bank behind it, works very well. I've replaced it with a RAV power bank (Amazon), 20,000mAH. There are two side pockets, deep zippered slits. When one power bank is fully charged, I replace it with either the Eceen or the RAV. So does my friend. The solar panel is held in place by a thin snap on lanyard and is easily removed if you want to place the solar panel in say, some tree branches. The power cable in the back is sufficiently long enough for that. This has a 2L bite lock collapsible hydration pack while mine has the 1L. Both are easily accessible and washable. Behind the hydration pack is a large pouch, large enough for a 10" iPad or a larger Android tablet. Inside top flap where the solar panel attaches to on the outside, sports a zippered pouch. I stuff mine with cables, adapters, and chocolate snacks. There's two side pouches as well. I keep a smaller solar power bank in one and a collapsible Platypus hydration flask (REI, Amazon) in the other. Overall, well constructed, comes in a variety of colors. Sturdy zippers, doesn't jam. Solar panel generates 7W power, same as the Goal Zero, Wagan, Bushnell but this one is detachable! RECOMMEND: Buy two (ordering my 2nd one).

I've had the backpack for a few weeks now and I've only used it to charge a phone once, and then just to make sure it worked as advertised. It seems functional in that respect but the bag has an overall flimsy feel to it. It's not very durable and the zippers are cheesy and low grade. This bag may be ok for hiking in an airport or along a highway but I have my doubts about it in the great outdoors. I don't think it would survive a briar patch or thick scrub very well.Priced fairly, given how much everything else costs these days.

Had one of the backpacks that was purchased for me as a gift last year. After almost daily use the backpack needed to be replaced. The battery pack and solar panel were still working just fine which is why I purchased the same backpack.When I received the backpack i immediately opened it and pulled out the solar panel and went looking for the battery pack which was no where to be found. Came back on Amazon where i found a video review which shows it comes with a battery back. Looking further at the page showed a question someone asked about if it came with the battery. The company replied stating for 2018 it did not. I then went to the product information section and found that buried in there was information saying that it didn't come with the battery.The battery along with the solar panel were a big factor when deciding to buy the product again so i will be returning the product.

Bought this for my spring break trip in Florida! The bag as a whole is great, and it's awesome that it comes with a huge battery pack to boot.Things I like:- Solar charger section has its own pocket.- The bag itself is quite spacious. There are also two exit points for nozzles on the shoulder, so you can pick either (or both!)- I really dig the color.Some things to improve:- The straps have no padding. It's not a huge deal, but they're very thin and can slide off the shoulders easily.- There is no place to store the nozzle when not in use, which is a bummer since I'll be having this on the beach.I would definitely recommend this bag. It provides the ease of mind regarding battery life, and the hydration pack is a huge plus. Just a couple of small things here and there and it would be perfect!

This thing is awesome. It will charge your phone ANYWHERE as long as its in the sunlight.

You gotta get this! Especially if you like to ride your bike everywhere or go hiking, the battery pack can charge my galaxy s5 from 20% to 100% once. Which isn't too shabby, i usually have a second smaller one inside when i carry this around). The water pouch is usable, but do yourself a favor get a nice one from sports authority or dicks, or even Walmart(one with a cap on the mouth piece, i find mine hitting the dirt during a hike when i sit down for a rest or the floor when i set it on the ground). The bag itself has plenty of room, enough for me to pack a netbook, the charger, a small pouch of cords, the battery pack, a smaller battery pack, my go pro, and 2 granola bars on the side pocket with a pen and a knife. all fitting comfortably on my back.
