No dog in this race, and I won't be buying one of these as I have enough batteries to last me through the apocalypse. However since I work with batteries I figured I should comment:
- The cheapest you'll get a halfway decent 2400mAh pack for (unsubsidized) is $30 or so: ~$24 for the batteries plus a few bucks for the enclosure/circuitry. I assume this uses 8x decent Samsung cells, around $3 each at large volumes.
- Even if the true capacity is 24,000 mAh (which I believe this is), it'll only recharge your devices to 19,000 mAh or so due to charging losses - about 10% upon stepping up to 5V and then 10% again when you step down from 5V. Every charger you can buy today has this same 'problem', of course, and there's no solution unless you want to start your own phone manufacturing company.
- Worse/cheaper batteries will not only have lower capacity, but their lifetime may be shorter. This pack will probably have a life around 400 cycles and a very cheap pack might have a lifetime of 100-200 cycles. Anything 'middle of the road' will be around 300 cycles.
- Samsung is one of the world's largest battery manufacturers and produces an absolutely ridiculous quantity of batteries per year. Statistically, they are one of the safest battery manufacturers by almost all metrics. Assuming they really do use Samsung cells in this pack, this would be one of the safer powerbanks you can buy. Additionally, the batteries in the 'exploding batteries' case were completely different and untested. I am almost certain that these Samsung 18650s are of a type that has been used for several years now with no problems - furthermore, unless you're Amish, you either have some Samsung cells in your home or interact with devices powered on Samsung cells in your daily life.
TL;DR it won't explode, the price is decent (assuming the cells are legit), cycles # is probably inflated but still decent, and you'll 'only' get ~19,000 mAh out of this because of physics.

Well, it's definitely a powerbank. It will definitely charge your phone. Seems kinda overpriced - Amazon had it for about $30 - but maybe the design is cool to some people. I can't find any specs whatsoever on the actual battery, and their "tech specs" page is completely useless, so I can't really say much about it.
When you buy batteries, you're either in camp A (you've got money to spend and you want something with High Quality Cells that'll last you many cycles) or in camp B (you don't care). Maybe you're in camp C (safety is critical) in which case you'll want to buy something expensive with cells that are actually proven to be safe.
The reality, however, is that unless you go for the _absolute_ bottom of the barrel (and I mean absolute bottom, for example the sketchiest seller you can find on Alibaba) you're almost certain to get something that is kinda close to its rated capacity and is completely safe. Cell lifetime is generally a factor of the price you pay however, so if you care about getting 400 vs 200 cycles out of a pack you should check the cells (and completely ignore all specs about cell lifetime given by the manufacturer.)
On an unrelated note, worrying about phone battery safety is hilarious to me. The most catastrophic event in consumer li-ion batteries was of course the Note 7, but even though that was incredibly catastrophic only 70 events were reported, the majority of which were fake. (This was out of 2,500,000 Note 7s produced.) Worrying about li-ion batteries exploding is like worrying about bird attacks: yes, they do happen, but they will almost certainly not be a real problem for you.
By the way, if anyone is worried about fire, there are far more dangerous things to tackle first. Do you own a washing machine or dryer, or live near someone that does? Defects in washers/dryers cause sixteen thousand eight hundred home fires per year, and between 15-51 deaths depending how you tally it. If you still have an irrational fear, that's fine: just buy a $9 ammo box, put your battery in that, and you'll be perfectly safe.

owenversteegThat's what I said to myself, there is no way this holds 24Ah of energy unless they figured out some new way of producing LiPo batteries with 4x more energy density than currently on the market with specs they provided. It would be nice if someone experienced could drain it and charge it back up properly and measure the capacity. 7-10Ah would be more reasonable and expected figure in my opinion.

clowndocI have the 20100 and love it. I also highly recommend anker's powerline+ cables. I've had great luck with most of their products.

Tech stuff isn't really in my wheelhouse, but I saw this drop, read the description and thought I'd do a bit more research ...
The $50 price with free shipping to CONUS seems like a solid deal for this battery. The best price I could find was about $63. For the extra $13 you're buying speedier shipping but that's about it.
The reviews on Amazon seem to be glowing (no pun intended) with the emphasis being that this really holds its charge - enough to overpower (again, no pun intended) the competition. Also, I assume this has overcharge protection, etc.
As the Massdrop description seemed to be a bit lacking, I've included a link to the Amazon page. Again, if you want it yesterday and have access to Amazon, they seem ready and willing. But if you can wait a little longer, money is money and the $60 price hasn't even been offered for a while on Amazon. At the moment, the savings would be $13 for a little patience.
I've also included a link to the manufacturer's info page FWIW. However, the new Massdrop web-design will not cleanly separate two links. They're there, you just have to look for the http:// for each.
I hope this helps anyone considering the purchase.

Even my Dell Venue Pro 8, which charges on 5V/2.1A, won't charge from any of my battery banks, even two that I have with specific tablet ports rated for 2.1A.
My Dell VP8 will charge from any 5V/2.1A USB supply hooked up to AC though. I really don't understand that.
Frankly, the Dell VP8 has been very finicky and also a bit of a lemon, so I'm not buying another tablet from Dell. They are part of the PC "race to the bottom" where low price, frequent sales, and coupon codes seem to trump customer experience.

ManMcManUnfortunately it wont. All the restrictions on hazmat materials like big batteries are only getting tighter and more expensive. This product actually can not ship in a single shipment on an airplane as it is above 300 watt hours. It is completely restricted. Batteries that are not restricted the shipping price has pretty much tripped in price. So even the Powerbanks that we could ship would not be worth it as you could source something locally much, much cheaper. Sorry Dude.

Thanks for the thorough response at least. Always nice to get some info on these kinds of things, as I was completely unaware of the situation before.
Happy New Year

Disappointed. Cheaply built - button, charging lights, and "led flashlight" are all really janky. The microusb port to charge the battery is sunken inside the case and almost no cables will fit. Edges are sharp.

Woulda loved this if at least the input was type-C. I hate carrying Micro-USB cables around.
