Voltaic Systems Converter Solar Backpack Charger - Includes a Battery Pack - Powers Phones Including iPhone, Tablets, & USB Devices

After researching WUSH bag requirements, I chose the Voltaic Systems Backpack because of its solar backpack charger and removable battery pack. Upon receipt, I found the bag exceptionally designed and smartly executed, with ample storage compartments in a compact size. I highly recommend this bag for those interested in packing for an immediate emergency evacuation lasting 2-3 days. If you need a Go Bag, seek something larger.

I bought this for my daughters travels in the US and abroad. We have used it as a carry on, and it saved us soooo many times we needed a phone or computer charge. Went through security with no problems. A great purchase.

One of my best purchases ever, love it!, I travel a lot and this backpack is always with me. The charging process is a charm and it manage to charge my Galaxy Note & my cell phone in a blast, it also works with small cameras. Be aware that eventually battery will need to be replaced though and it's certantly not enough to charge a laptop. Also the backpack is very confortable to use, it distribute the weight in an excellent way (i has some problem at my lower back after an accident so i can tell the difference with other backpacks inmediately) Also, an defenitely a plus, the fabric of this small wonder is waterproof and made with recycled soda bottles.

This is an awesome backpack. It fits all my paperwork and it also is perfect for carrying my MacBook to and from work without getting damaged. Even though I live in Cleveland Ohio, which happens to be 5th cloudiest city in the USA, it charged the power cell in no time. It is a great added benefit when you realize that you forgot to charge your phone and your backpack is also ready to go as a phone charger. This backpack would be great as a backpack alone for $99 but the added solar charger makes it worth way more.Voltaic Systems - Converter 5 Watt Solar Panel Backpack with Backup Battery Pack - Matte Black | Powers Phones, USB Devices, & More | Charge Your Device as Fast as at Home

update: the zippers really suck. they dont unzip/zip easily and over time did not loosen up. the laptop compartment zipper pull broke on me it was so tight. the rest of the bag seems to hold up well. hopefully newer models use better zippersI picked this up after using a much lower-cost solar bag for the last few years. I got it for next to nothing on sale, and it was ok. the straps weren't the strongest, and the solar panel was rated at 3watts, but it DID work, until i slammed it in the trunk and caught one of the straps and broke the plastic ...retainer(?). I'm fairly certain any bag would have broken. but... time for a new one, so I ordered the Voltaic Converter. Its certainly heavier than my old one, but in a good way. one that conveys some quality. its more comfortable to wear as well.Things I'm not crazy about:- The zippers. They don't open /close the smoothest.- the angled microusb plug. I swapped in my own battery pack because its bigger and has two ports, but the way it plugs in now blocks a port... my old bag had a usb plug and from there i'd plug in my own cable to either a device or battery. here I'm stuck with this angled microusb plug. I'd rather have my 15600mah battery pack vs the 4000mah one that comes with it.- its kind of front heavy. as in, i put it on the ground and it falls forward. I guess if I had a heavy laptop in the back it'd balance out, but I have a tablet and kindle there, that's it.- The water bottle holder is REALLY tight. I use a kleen kanteen type water bottle and have to really try to jam it in.These are really all nitpicks though...Things I like:- higher wattage solar panel compared to my old bag. I plugged in my battery pack indoors near a window and it lit up, starting to charge. My old bag needed more direct light.- bottle holder is nice and tall, there's no way its falling out- straps are comfy- bag feels well made overall- looks professionalThings I wish for in future versions:Ditch the angled plug or let us use our own?put a rubber grommet inside the top pouch so I can throw my phone in there and charge it, instead of trying to cram it on the side pocket with the battery packpad the laptop area divider with what i presume is for a tablet or something?the zippers do suck...Overall, these are all nitpicks and I don't think you could go wrong with the bag, especially compared to a lot of the other 'solar backpacks' out there.

I just started using my Voltaic bag today. I received it in the mail yesterday, at the minimum arrival date (the 16th), which was cool because I was worried it would show up late (the 19th). The bag has been working perfectly. The solar panel is really rugged. I like the front pocket for storing electronics, however it lacks security. I may consider adding a padlock to that compartment. Overall I was impressed with this bag, but for the price it could have been a little nicer.

Bulkier than I expected and the solar power doesn't charge that great. In fact it takes a while just to charge up when it's plugged in.

great backpack! Zippers are ok. Perfect for solar sales!
