SunJack Solar Charger + Powerbank

Ok so I've read some older comments and I'm going to summarize my question as this: 14W with 1 quick charge battery or 20W with 2 quick charge batteries, all with pass through charging and in a nifty designed case that is the solar panels. Is this really worth the money for the complete package? It seems so to me but I'm still new to this type of innovation. I'm slowly but surely moving into rechargeable batteries and I am meeting a solar power company rep in 2 days to see if I can afford to get into solar powered energy (despite Nev. Energy having a nasty monopoly on energy here in Vegas). I have a charger I bought from IKEA that's just under 11,000mah but it's slooooow (I expected it but didnt realize just how slow since it's been some time since I used a battery to charge a device)). The IKEA battery was around $15 and I figure it's good enough to power up a device overnight (namely my son's ipad) or as a real emergency need BUT I have wanted to upgrade my older solar panel battery kit which is probably circa 2014 and I haven't even used it yet; it's an emergency use situation. LOL...So what is the consensus on this drop or at the very least, the company and items? Thanks!

TRexSrGenerally speaking, how long would the 5W version take to charge up the average smartphone?
Also, does anyone know of a good AA battery charger that would work with this? I have Eneloop batteries, but have one Li AA battery that came with a compact flashlight, and am interested in moving to all Li for flashlights. But I would need some kind of USB charger for them. I think MD recently offered a torch that had a micro or mini USB charging port. Perhaps they should offer it again.

TRexSrWell I searched a bit and damn there is a huge savings here on MD for the 14W and 20W with battery(s). I compared against the Sunjack website and Amazon and MD wins hands down. I now have to decide which option to go for, I'll probably go looking for a way to charge some Eneloops too.

TRexSrI got the 5v one on the last drop. My impression is that it's lucky it has a wall plug because it sat in the Texas sun for two days and didn't fully charge. It's too big to strap to backpacks and only has one loop anyway. I would advise buying a lighter battery charger that charges by plugging in.

TRexSrI must add to my earlier respones-
I believe the 14 and 20v charge faster than the 5v. I wish I had upgraded for this reason but it's still a pretty cool little device.

WonkwonkI recall some saying they got a bad panel pk so I would hope a decent warranty remedies that situation. All of them have the same output more or less but it does seem the 14 and 20W versions harnesses more light which should translate to more efficient/rapid charging. It is somewhat ambiguous that the 14W is rated to charge their 10k mah battery in and around 5hrs but the 20W says "2 batteries" around 5 hours. Can’t be sure of that because 6W differemcee doesn’t seem like a lot to have 1 panel charge 2 batteries in the same time that a 14W panel does for 1 battery. I bet you can charge a battery and device at the same time efficiently if you want to go that route. Still, if you get a good panel, MD seems like a sweet price compared to Amazon and more so from the manufacturer‘s sight. I want to get in on this but current budget needs are slapping me straight. Ugh...

TRexSrKeep in mind that the 20 watt panels are a little bigger than the panels of the 14 watt models. I’m not an engineer, but it may help charge the second power cell in the same amount of time as the 14 watt model.
