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

Was happy when the backpack first arrived, but soon experienced issues regarding the solar panel and then the battery. A representative from the company contacted me requesting feedback for the product, and I mentioned how the solar panel wasn't efficiently charging my battery. He provided excellent customer service and was prompt with his reply. He suggested it may be because the solar panel itself, and sent a more powerful panel which I was able to use to power the battery a total of two times, and then my battery broke. The metal portion of the charge outlet on the battery fell into the battery itself, and now I can't charge the battery at all. The charger does not fit correctly into the batter since it is missing the metal portion to hold it snugly in place.I was happy with the product, but I feel that the quality is lacking. Maybe I just had bad luck with it, but when I contacted the representative again asking to either replace or fix the battery, I did not receive a response. Now I feel as though I've just bought an overpriced backpack, not a solar backpack since I cannot utilize its solar power capabilities.

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.

This backpack is not built well. I bought this in April of 2015 and 4 months later it has failed spectacularly.1. The female end of the battery broke within a month. Amazon was nice enough to refund me enough to buy a new battery pack.2. The divider between the two sections now has a huge hole in the top.3. The solar panel has failed. It will not charge anything. It did work for a few months, but even then, it never really charged very well.This was from light (laptop + notebook), city use.I wish I could return it, but apparently, I'm outside the window :/

I have been using the ECEEN backpack for a month and I am happy with it.  A few minor cons but that's it.The ProsIt comes with a 1.8L Bladder bag and 7 Watts Solar Powered Panel to charge your devices. I am a fan of slim fitted backpacks in general so this was a plus for me.  I like how easy it is to fill by just simply twisting the cap unlike my CamelBak where I have to use a bit of force to twist the cap. Another plus is the extra storage compartments inside the bag, Especially inside the pouch area. I like storing extra things. The overall design of the backpack catches people's eye everywhere I go. From the slim fitting city sleek style to the in-season dark red color. This backpack also makes a good bag to wear at conventions such as Comic-con because you are able to hydrate and charge your devices in direct natural lighting. I like that you can detach the Solar Panel to give the bag a different personality.The ConsThe tiny flaps that holds the Solar Panels seems to be poorly made. It tears up quicker for some reason. I wish the Solar Panel came with a battery pack because that would make things much easier in terms of charging. If you want to charge your devices, you have to stand in one place to charge. If you like fashion, tech, and fitness, ECEEN's Solar Panel Hydration Backpack is worth investing in. You will certainly grab people's attention by just wearing it. I know I have.

Backpack is fine & solar panel works great. The USB port is difficult to plug into with the way it is attached to the solar panel, but I just got one of those short USB extender wires to make it easier. I also like the zip compartment to hold your charging item against the panel so it doesn't disconnect - but beware the solar panel and the spot behind it can get very hot if it's a hot sunny day, but on a cool sunny day it's fine.But the power bank is TERRIBLE!!! I have cheap under $10 ones that are so much more reliable. From the start it seemed glitchy, but then it would seem like maybe it would work, but then it wouldn't again. Total crap. Can go from fully charged to dead in minutes. Plus the power "button" isn't really a button, and I find it unresponsive rather often even when the charger still has a charge left. I keep trying to use it because it's a slimmer design than my best charger, but I keep getting screwed thinking I have a freshly charged charger that ends up being a total dud at least half the time I need it....
