I recieved my 20w unit nice looking piece of kit. Seems to charge when cloudy, slow but it does charge. BEWARE the battery packs are the inferior "lithium polymer" these will catch fire if over charged or damaged slightly , recharge cycles are half of lithium ion. These packs are hard to find as manufacturers have gone with the safer and longer lasting lithium ion. If it had said lithium polymer in the description I don't think I would have purchased.

Yes, same battery tech unfortunately. Sunjack still lists Lithium Polymer as the tech for the power banks that come with the solar panel kits in the current generation products they sell, but they definitely show a 10,000mAh for the 14W.

I did not go on their site. When I recieved mine there was a tag that said congratulations your batteries have been upgraded to 10,000mah I thought that was strange as the drop did say 10,000mah. I'm selling my batteries and buying Li-ion. Want to buy them lol
I have a solar charger in the closet. I found that a solar charger doesn't really work very well while strapped to your pack and on the move. It works fine if you set it up stationary and wait for it to charge. On the trail the sun is broken up by canopy and turns. We pretty much hike from dawn to dusk so solar just wasn't the answer. We wound up getting a little bigger battery and just charging it before hand. It weighs much less than a panel and a smaller battery.

Totally agree with this approach based on my experience. Solar chargers are only useful if you are going to have a “base camp” where it can sit stationary in the sun (ideally rotated as the sun moves across the sky, especially during any season but mid summer).
If you think of a battery pack as a 5 gallon jug and the panel as an MSR pump filter, it helps. The problem is that without a very big, heavy panel, the rate at which the jug refills is very slow; 10,000 mah is a pretty big “jug”. It will take alll day or even multiple days if the sun is not full brightness to refill completely
I would love to order, but why no International shipping?
BE WARNED: " SunJack Solar Charger + Powerbank" This is a blatant lie. This drop does NOT include a powerbank at the $29.99 level.
FWIW, I use a Goal Zero Nomad 7 (2-panel 7 watt) charger on hunting and backpacking trips. I pair it with a Belkin 6,600 Mah battery pack and combined they weigh 718g or with the GoalZero Guide 10 pack and combined they weigh 600g . That is only slightly less than the 14w panel and 10,000 Mah battery in this drop, which represents a significant boost in both charging speed and capacity (if the specs are to be believed). If I didn’t have the Goal Zero already I’d be seriously considering this 14w bundle. Very handy for recharging headlamp, Earthmate, and smartphone while on trips lasting more than a couple days. One nice thing about the "Guide 10" battery pack/charger versus a typical "battery pack" like the ones on this drop is that it holds 4 AAA or AA batteries (3,200 mah or 8,000 mah respectively). The Guide 10 can then be used as a traditional "juice pack" like the ones included in this drop (albeit with less capacity), OR you can pull the batteries out to power a device such as a flashlight or headlamp and then pop another set of batteries in to be charged while you're away from base camp.
ONE IMPORTANT THING TO NOTE: Everyone gets hung up on charge times with solar panels. One disadvantage of these Sunjack solar panels is that the charging output is limited to a pair of USB ports. By design, USB ports are limited to 5 volts and ~2 amps each (max output ~10 watts). This means that if you are using the 20w panel to charge a single device, you have more panel than you need, since the total panel output is ~20w, but you are limited to using ~10w of that output. Obviously having a 20w panel will ensure that you're getting 10w of output in less than ideal conditions (assuming that the panels are all feeding the charge controller rather than 1/2 of them being wired separately to each of the USB ports). Charging a phone directly from a solar panel often doesn't work well because if the phone detects a voltage or current fluctuation outside a pre-determined range, it will shut off charging. I experienced this recently with my iPhone Xs and a solar panel. Solar panels are usually better used to charge an auxiliary battery, which is then used to power devices.
Interestingly, the battery pack(s) included in the 14w and 20w panels are compatible with QC3.0 charging, which charges at higher voltages and therefore charge much more quickly. However the solar panels don't support QC3.0 output, and no QC3.0 charger is included, so unless you have one, you'll be limited to old-school 5vx2.4a charging from a wall mount USB charger. Assuming 70% efficiency, that will mean about 6-7 hours to fully charge one of these from completely empty to completely full. With the 20w solar panel, you're probably looking at >a full day to charge from completely empty unless you are in the Arizona desert in mid-summer. :-)
Why no Intl. Shipping?
I have yet to use mine, and have it stored away for some future trip or disaster prep. Anyone who really knows batteries have recommendations for proper long-term storage? Do the batteries need to be charged on occasion? Also, once it has been used the first time, does that change anything as far as requiring a certain charge level to be maintained?
Why no postage to Australia ????????????
i love the idea and i continue to love massdrop, but the 20W is a few bucks cheaper with amazon prime.
exitjones
I was just looking at Amazon, and theirs is for the panels ONLY for $99. I don’t have prime so I’m just going off regular price. It looks better here.
FireMike
@FireMike good point and i stand corrected. this is a pretty good deal after all.
"Hey why no international shipping" etc etc. Come on folks, lose the powerbank and throw your international customers a bone.
This is the Third time I have seen this item on Massdrop. Every time including this time the largest solar charger is sold out by the time I see it. If each time you post this drop you run out of the 20W units maybe you should arrange for more of those or just have a drop for the 20W units.

Thank you MD for listing this again so soon. I was able to get the 20W option this time. For those who missed out, hang in there! Maybe MD will list it again not too far out.
Somehow i doubt it would charge enough to make anyone a happy camper, especially hiker. A gimmick to me unless someone can prove otherwise.
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!

I 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...

Keep 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.
Funny thing is, they do have an option for just the panel, just it's the 5W related to the base price. However, it's a bit misleading that the title of the drop says ..."Charger + Powerbank" with a base price of $29.99 but the base item doesn't include a charger.
NOT AGAIN MASSDROP!!! Please add option to choose only the solar panel (without battery) next time.
just wanna make a suggestion in the next drop... there should be an option to choose the solar panel only (without the battery) so that all members here on any country can join this drop
The 20w is $170 on Amazon and only $95 through this drop. Seems to good to be true, what am I missing here?
Thenw84
If you look at just the panel, the Amazon price for 14W is cheaper. 14W on Amazon is $64.95, 20W is $99.95.
Can't ship to the philippines? what's d reason?

I can only surmise that is the manufacturer not the distributor that determines what is for sale. Hence, MD is only allowed to offer what is available because Sunjack doesn’t want to sale the panels (14w,20w) by themselves. In my personal research, I have read it is better to use the panels charge a battery and then use the battery to charge the device. This way heat (iPhone in the sun) or intermittent sunlight doesn’t become a problem. I am curious on what more seasoned users/askers of the panels w/o the battery bank have in mind for powering their electronics.
TRexSr
i understand what you mean but they should allow the panel only so it can be ship worldwide. almost all of us have the powerbank already don't you my friend?
Will you be able ship outside US?
Does the powerbank support passthrough charging? "A mobile device can be charged simultaneously while the device is being charged" sounds like it, but could also mean that I can connect a device to the second USB output of the solar panel to charge it at the same time as the powerbank.
Harachteh
I own this panel and can confirm that both USB outputs from the solar panel can be used at the same time. One for the powerbank and one for another device, or two devices or two powerbanks, etc. Just be aware that using both outputs will slow down your charge time for both connected devices.
Do the 14W & 20W bundles come with the SUNJACK Qualcomm 3.0 Quick Charge Battery Packs (with USB C) as described on their website? or are they older battery models?
MochiKrunch
Just received my bundle and it did come with 2 - 10,000 mAh Qualcomm 3.0 Quick Charge Battery Packs with a USB Type-C port. The box it came in, lists the specs as 8k mAh batteries but upon opening, there was a note that says the batteries were upgraded to 10k mAh batteries
Can you charge a smart phone with the 5V option?
Please ship outside US
Disregard my last comment. The box the product came in read that two 8,000 mAh  batteries were included. When I checked the back of the included batteries they were 10,000 mAh rated. Perhaps this was just shipped in an older package for savings.
I also received two 8,000 mAh batteries instead of two 10,000 mAh batteries in my 20 watt kit.
Did anyone else get two 8,000 mAh power banks instead of 10,000 mAh with the 20 watt kit?
nastynate13
My package read two 8K mAh batteries were included. When I checked the back of the batteries they were listed as 10K mAh. Could be an older printed package that Sunjack was  trying to use up.  Check the print on the included batteries just to be sure. Hope this helps.
I received this in an email today
"Due to an unexpected delay, these orders may ship later than the original estimated ship date. Our apologies for any inconvenience. If we find that the drop is going to be delayed by more than 30 days, we will let you know.If you would prefer to cancel your order, please contact Community Support using the “Contact Support” button on your transactions page and our Community Support Team will be able to help cancel your order up until it is ready for shipment. "
So estimated ship date was Oct 20th. It is now Oct 25th and we have received no update. Can you please tell us what is going on with the drop?
So does the 5 watt model come with a battery? Cause under the "Included" it only lists a USB cable, manual, and warranty. But under "Included" for 14 and 20 watt models it lists one battery for 14 watt and two batteries for 20 watt. So please straighten this out
vikesguy62
Hey vikesguy62 the 5 watt model comes with integrated 10,000 mAh battery.
Can these be daisy chained together? Hello!?
@Tyler this drop is misleading and presents the full size panels with only 1 small shitty picture of the actual 5W panel.
