I bought this specifically because it's touted as being able to charge an iPad. I've tested it now for over 6 months with iPhone, iPad, and (with adapter) AA camera batteries at several latitudes (Phoenix to Seattle) and over several seasons (summer-winter). It's performance far surpasses that of a MUCH more expensive 10w B*u*t*n model purchased at REI a year or 2 ago that I returned due to worthlessness.
As you'd expect, it works better in the summer in AZ and at higher altitude than in the fall & winter in WA & OR. Solar cells need strong sun to work well, period. It easy charges an iPhone about as fast as wall outlet in strong sun (45-80 min.). iPad performance is OK, not stellar, it does work but plan to set aside most of the afternoon (4-5+ hours in strong sun). I've really never achieved a full, 100% iPad charge but it did keep me going for extended Kindle reading at remote campsites. I have had success charging on the car dash as well.
Chinese solar cells have come a long way in price & performance in the last year or so. BTW, this model has increased 20% in price in the last few months, and I would still give it 4 stars at the higher price. It's a bit too heavy for extended backpacking (maybe on an overnighter it'd be OK, but I'd think twice before humping this brick on a long trail). The sleeve has a very handy pocket for the battery, cables and adapters, and the loops make it a cinch to hang from a tree, etc.
Summary: Well worth the purchase price, I'll give a solar panel 5 stars when it works as well as an outlet.The solar panel is impressive and the battery is effective. However, the battery is described as 5600mAh when it is really 5200mAh, a different product. The battery's output is 1amp which is not effective for charging an iPad 3 or 4. The panel will charge the iPad 3 directly, however, in direct sun. When charging an iPad 3 directly, if a cloud passes by, the charging will be interrupted. Instapark sells a 6000mAh, 2amp battery.I needed this for PCI (Personal Continuity Initiative).
I got this item specifically because it can power an iPad. The idea is to get electronic versions of all of the survival manuals and keep them on my iPad in my bug out bag. So after the SHTF, even if all the batteries fail (including the one in the iPad), I will still have enough jooce to figure out how to survive!
This is awesome! Now I just need to get thirteen more of these for all the USB stuff I have! A cell, a navvy, a tablet, a water purifier, radios, netbook, batteries and my desktop warfare USB cannon. And for my electric blanket, of course.I bought this product last December and I can't tell you how much I'm satisfied. It helps me stay in touch with my family while I'm right now in a remote area in Haiti where only the sun provides in energy. Some neighbours also benefit from it, because of its 2 USB ports.Cool to have got it!
