A great deal, similar to but cheaper than this one.
Now $15.19 using the 50% click-to-apply coupon (will be applied at checkout) and stacked with the 10% promo code U8AQQBGV
CamelCamelCamel.
I tihnk you might need to click redeem on the product page under the 50% coupon (worked on mobile)
Possibly targeted or Prime accounts only?
On my desktop browser it shows the 10% code directly underneath the check-to-apply 50% discount
Not the biggest capacity you can get these days but good bang for your buck. The fact that it's airline approved made it appealing to me. Got one at the deal price.
Worth note: LiPo not LiIon.
They still work fine, just be aware when storing/carrying it and such. LiPo is more volatile than LiIon, and places like hot cars or backpacks in the sun, are not a good idea.
INIU it
wow that's a big deal….all the Lipo batteries I used in the past swell up like crazy after a year or so..I'd rather not burn my house down
it's a great deal if you want to 'Lipo' your house …
wait - I recently bought a cheap 10000mAh 37Wh battery in Japan from like a DAISO - for around AU$13 - this model - https://www.amazon.co.jp/-/en/HIDISC-HD-MB10000TAWH-PP-Compa… - which I've just read is LiPo (Lithium-ion polymer)
I do seem to recall some warm feelings down there while walking around during recent travels. Do I need to worry - or just take care to keep it out of hot places - is it likely to explode if I carry in it my pocket cabled to/recharging my iPhone ?

Never knew the difference but read this?
Seems to indicate the opposite or have I misread this?
The phrasing is poor.
Cylindrical Lithium Ion Cells might explode then catch on fire as their failure mode. However flat lithium polymer cells will instead burst into flames.
They'll both catch on fire.
Lithium Ion cells are more naturally stable in what's being discussed regarding heat in that they won't spontaneously catch on fire.
You can think back to the note 8 incident as an example.
Most lithium polymer batteries are fine, but they really don't do well with heat and cheaper ones start to degrade and swell very easily, and eventually if you keep using swollen batteries they can burn up and self ignite.
Also worth knowing there's a lot of info that's straight up wrong on the site. Info about density, about price, about efficiency, about charging capacity and life, and a lot of things. Some of it might be poor phrasing but it's certainly misleading.
It matters what you compare to, but when comparing the best of each category a majority of this site is wrong.
Yup this is accurate. The best way to identify whether a bank is using lipo or liion cells are by how thick it is.
The two most commonly used Li ion cells are 18650 and 21700. Meaning any unit thinner than 20mm is pretty likely to be using those pillow cells.
If you live in hotter areas, leave your bank in the car or anywhere where it could get warm, it's worth noting that these will perform worse due to them trying to manage their thermals so they're not very usable in the heat, internally they degrade faster, and subsequently there are at risk of puffing into pillows and catching on fire.
Generally the most durable, long lasting and efficient banks will be the thicker ones (assuming we are talking 10-15k mAh), but because these are lower power they tend to last a bit longer than the higher power variants depending on your use.
But if you're buying these, don't expect them to last longer than 12m without issues or them dying.
Unfortunately you get what you pay for with cheaper banks and these are fine for a small set of use cases and if you really can't get much better.
Nah, LiIon pouch packs exist commonly too. They dont have to be cylindrical cells.
Yes they do, they're never used in battery banks.
I have never come across one in over 350 banks.
@SmoothCactus: I own 2. One puchased from kmart and one from target. Both their "store brands".
I was glad they were LiIon, i checked the specs before buyng them back in 2017 :)
Lipo pouch packs use the same chemistryas their 18650 counterparts, Lithium Cobalt Oxide. All that varies is the form factor. 18650s are more modular and can be used more widely, Pouch packs tend to be application specific.
You mean LiIon pouch cells, right?
Lipo 18650's do exist, but are uncommon.
Both use same chemistry, just different form factor. The pouch packs just make more efficient use of available space. There are tweaked versions in the form of LiHV which allow slightly higher voltage but they also come in cylindrical cells (18650 etc) and pouch packs. Whether they're cylindrical or pouch packs make no difference, both equally as volatile.
The only other variant I'm aware of is LiFePO4 which are suppose to be slightly safer, higher longevity at the cost of energy density.
I bought one of these when it was $18.
Its not appearing with the 50% coupon sadly. Possibly if you have bought it before it wont let you get another for 50%
I bought one at $18.99 a few weeks ago and I'm seeing both the 50% and 10% discounts now.
Edit: Looks like it's expired now
Possibly targeted? Only a 10% voucher listed for me and code doesn’t work at checkout
Doesn't work
I am seeing 10% discount only and that too with coupon code. Not seeing check-to-apply anywhere on whole checkout page!
Working
$19 now with 40% coupon and 10% coupon stacked on top.
When I entered "U8AQQBGV" as the promotion code, I got the following error:
